DIY vacuum table. Vacuum table made of MDF. Types of vacuum tables for CNC
Nowadays, you can see products everywhere that are made using technology vacuum forming. This approach allows you to quickly produce plastic dishes, packaging, mannequins, paving slabs and much more. To do vacuum forming at home, you will need special machine. Such devices are expensive, and they are too bulky. This article will look at an example of creating simple machine vacuum forming, which uses only a vacuum cleaner and an oven.
Of course, the power of such a machine will be small, so it will not be possible to produce bulky objects or simply make a large number of products in a short time. But for the sake of interest and small household needs, such a machine is quite enough. In addition, with the help of such a machine you can perfectly make cases for various models, be it ships, planes or cars. You can also make elements for various homemade products. This device is a kind of original analogue of a “3D printer”.
Materials and tools for homemade work:
- vacuum cleaner (the more powerful, the better);
- oven (needed to heat the plastic);
- wooden blocks;
- drill;
- self-tapping screws;
- screwdriver or screwdriver;
- plywood or chipboard (thickness 16 mm);
- silicone (as a sealant);
- Fiberboard for the working surface (plywood is also suitable);
- aluminum tape;
- wood, plaster (or other materials to create a form).
Machine manufacturing process:
Step one. Vacuum machine dimensions
The main element of a vacuum machine can be considered a frame on which the plastic is heated, as well as a vacuum chamber. The dimensions of the frame should be such that it fits in the oven. You also need to take into account the size of the plastic sheets from which future products will be created. The frame is made of wooden blocks.
Step two. Making a vacuum chamber
The vacuum chamber is needed to “suction” the plastic, which, in turn, will envelop the mold underneath. To make a vacuum chamber you will need a 16 mm thick chipboard sheet or plywood. Technically, a vacuum frame is a box; its dimensions must correspond to the dimensions of the frame that will rest on it.
First, a frame is made from timber, and then plywood is screwed to its bottom. Since the chamber must be sealed, all seams must be coated with sealant during assembly.
The vacuum chamber also has work surface, that is, the place where the formation of products occurs. It is a sheet with evenly drilled holes. Fiberboard works well for these purposes, but plywood can also be used. It is important to understand that the working surface should not sag, so a spacer is installed in the center.
Step three. Connecting the vacuum cleaner
To conveniently connect the vacuum cleaner to the vacuum chamber, the author used a vacuum cleaner attachment. It needs to be screwed to the vacuum chamber, having previously made a hole in it to pump out air. The nozzle is attached using self-tapping screws; it must first also be lubricated with silicone or other sealant.
If there are doubts about the tightness of the structure, it can be glued on top aluminum tape or other adhesive tape.
Step four. DIY molds. Product creation process
To create a form you can use various materials, for example, gypsum, wood and others. If the forms do not have to be perfectly smooth, then polyurethane is ideal for these purposes, since it can be easily processed with a stationery knife.
If there are concave places on the form, then you need to drill holes here so that the plastic can be “sucked” into these recesses. A drill with a diameter of 0.1 - 0.5 mm is suitable.
Once the mold is made, you can proceed directly to the molding process. The work will be carried out in the kitchen, as access to the oven is required.
First you need to connect the vacuum cleaner to the vacuum chamber and place the mold in the center of the working surface. At the bottom of the mold you need to place spacers 1 mm thick; coins will do. This is done so that the plastic fits the shape at the bottom better.
Then you need to cut a sheet of plastic around the perimeter of the frame; PVC, PET and other types are suitable. Due to the fact that the vacuum cleaner does not create a very high vacuum, it will not be possible to use thick plastics. The thickness of the plastic for this homemade product should be in the range from 0.1 to 0.4 mm.
The sheet of plastic must be nailed with staples, maintaining a distance of at least 2 cm between them. There is no need to spare the staples, since heated plastic can easily break out of its fastenings.
Now you can place the plastic in an oven heated to 190 degrees (for each type of plastic there is optimal temperature softening). After some time, the plastic will heat up and begin to sag in the frame. Now it needs to be removed and installed on a vacuum machine. Subsequently, the vacuum cleaner turns on and the plastic begins to envelop the mold. When working, you need to use gloves, as the frame will be quite hot.
The vacuum cleaner needs to run for about 20 seconds, then the frame can be removed to remove the product. If in some places the plastic does not adhere well to the mold, you can use construction hairdryer.
That's all, now the product can be processed at your discretion and painted in required colors. According to the author, such a homemade product can work without problems with a type of plastic such as polyethylene terephthalate, which is what bottles are made from. Well, what to do depends on the personal needs and fantasies of each homemaker.
The vacuum table makes installation on the table much easier and faster. milling machine CNC sheet materials. These can be sheets of MDF or acrylic... Moreover, if the sheet is curved, then vacuum fastening allows it to be leveled during operation.
If MDF is regularly processed on the machine, then the machine is probably equipped with a powerful exhaust hood (vacuum cleaner for collecting chips and wood dust - see photo below). Such an extractor with a power of 2.2 kW is capable of not only removing sawdust from the cutting zone, but also ensuring the operation of a vacuum table.
ATTENTION! Operational safety is guaranteed only under certain conditions: the size of the cutters must be no more than the permissible clamping force of the workpiece, the cutting mode must only be tested with the existing vacuum table. Otherwise, the workpiece may be torn off during processing, which can result in serious injuries or even death.
The vacuum table is made of two layers of MDF 20mm thick. Upper layer- front - needed for suction of sheets of the processed material. The channels on it are divided into six zones (see photo below), which, if necessary, can be drowned out one at a time, depending on the size and configuration of the workpiece being processed. The cross-section of the channels is chosen so that, if necessary, each zone can be sealed along the contour using a household rubber sealing tape with a D-shaped section (tape for sealing windows and doors). The tape is equipped with a self-adhesive layer and is well fixed in the channels. The depth of the channels is selected so that when the vacuum table is turned on, the workpiece lies on the table surface, pressing the sealing tape.
The bottom layer of the vacuum table serves to supply vacuum separately to each zone of the top layer of the table.
The channels of the upper layer have vertical holes to bypass the vacuum from the channels of the lower layer to the channels of the upper layer. There are 4 such holes. for each zone. However, the greater their number, the better.
The easiest way to connect a vacuum table to a vacuum cleaner is using a ubiquitous pipeline, such as a sewer line (see photo below). It is both cheaper and more technologically advanced. The photo shows that a pipe was used to supply vacuum to the machine sewer diameter 110 mm. The vacuum is supplied directly to the machine by six corrugated hoses with a diameter of 50 mm. Each corrugated hose is docked to the vacuum table using a fitting screwed into the table.
All connections are hermetically sealed either with standard seals or clamps (preferably using sealant).
Before assembling the table, all its channels should be treated with PVA glue or primer to ensure that the MDF is impermeable to air (MDF does have good air permeability).
The top layer of the vacuum table is screwed to the bottom layer with self-tapping screws. To prevent the screw heads from interfering with working with the table, there are holes in its surface into which the heads are recessed.
After assembling the table, its surface should be processed with a milling cutter to ensure a flat surface.
Summary
As can be seen from the photo, a vacuum cleaner with a power of 2200 W is used in this design. This vacuum cleaner has a tee at the inlet for connecting three air ducts with a diameter of 100 mm. During all the work, one hole of the tee was occupied by a vacuum table, the second - exhaust system with an inlet hole of 50 mm. The third hole was half-opened to avoid overheating of the vacuum cleaner due to low air flow, because. the vacuum table does not provide air flow at all, the hood has an inlet opening of only 50 mm, i.e. the cross-section of the inlet hole would be only 50 mm instead of 3 holes with a diameter of 100 mm. With this connection, the power of the vacuum cleaner was sufficient to operate the vacuum table and the system for suctioning chips from the cutting zone.
The clamping force of the workpiece on the table depends greatly on the clamping area. An MDF workpiece measuring 600x900 mm can be processed with a cutter with a diameter of 6 mm with the entire diameter to a depth of 6 mm in one pass at a feed speed of 2000 mm/min. In this mode, such a vacuum table is capable of holding the workpiece.
For greater reliability, we can recommend using stops along the edges of the workpiece so that the workpiece cannot be moved during processing. Such a solution will be useful, for example, in the event of a vacuum table failure during operation or in the event of an unauthorized excess of the cutting force. At the same time, the complexity of installing the workpiece on the machine table will not change, and perhaps will decrease (the stops will allow you to place the workpieces in the same place).
In addition, it should be borne in mind that the workpiece on the vacuum table can easily be torn off by vertical force. When planning processing, this should be taken into account and not use cutters that create a lifting force during operation.

Design of vacuum tables
The top part of the table is made of durable aluminum alloy 3mm thick. Usage epoxy resin in design, provides good protection from dents and bends.
The base of the vacuum table has a “honeycomb” structure and is made of a material that reduces the effect of temperature differences on the unevenness of the table surface. The honeycomb design ensures uniform air flow across the entire surface of the table.
The “collector” measuring 25x25mm is located around the honeycomb base, due to which the best possible distribution of vacuum is achieved between all the holes in the table.
Hole size
IN standard version The holes in the table have a diameter of 1.6mm, and are spaced at 12.5mm intervals, which is optimal for most jobs.
Materials such as 127µm thick polycarbonate or vinyl will not deform against 1.58mm holes under the full force of a standard vacuum pump (see specifications).
Optionally, the holes can be custom-sized (minimum 0.79mm). The 0.79mm holes are countersunk on the underside for minimal air flow loss.
Fastening
All tables have a 9.5mm flange around the perimeter for mounting. If the fitting for connecting the vacuum pump is located not at the bottom, but at the side, then there will be no flange on this side. If necessary, mounting holes will be drilled in the flange in accordance with the customer's drawing.

Q: How can I secure the vacuum table?
A: The table has a 9.5mm bottom and top flange around the perimeter. You can use them for clamps or drill holes for fastening.
Q: Is it possible to use threaded connection for vacuum liner?
Oh yeah. Please indicate the required size.
Q: I already have a vacuum pump. Will it work with your vacuum table?
A: Most likely it will work. In any case, you can order the pump later. If you decide to use your own pump, you can immediately order an adapter/adapter. When ordering, please indicate dimensions.
Q: I work with materials that can be scratched. Is it possible to avoid them when working on a vacuum table?
A: Yes, you can use the switch valve to blow air out of the table. This will have the effect air cushion. Optionally, you can adjust the amount of incoming air. To control the valve you need compressed air pressure min. 4.2 bar.
Q: How flat is the surface of the vacuum table?
A: Tolerance no worse than ± 25µm/sq.ft.
Q: How should I secure the table to prevent bending?
A: As a rule, Bottom part The (surface) of the table is flat and parallel to the top, therefore, the table can be mounted on the base of the machine.
When installing the table on a surface, pay attention to the absence of gaps that indicate unevenness of the surface. Use shims to eliminate table wobble due to gaps. Check parallelism. If necessary, use additional spacers to eliminate the possibility of table bending under pressure and disruption of the plane of the working surface of the vacuum table.
Q: Is there a way to place items on the table in exactly the same place?
A: Yes, it is possible. An optional stop system for product positioning can be ordered. As a rule, these are three steel pins that are “pushed out” from the table while the product is being placed and “recessed” into the table as soon as the vacuum is turned on. It is possible to place more than three pins.

The manufacture of a vacuum table is the most critical stage in the design of a thermostat. vacuum press with your own hands. At the design stage, it is necessary to determine the dimensions of the table, select the material for its manufacture, and think over ways to fix and seal detachable elements to maintain internal negative pressure (vacuum). The vacuum table is made with the same basic set of tools as.
Further in the text, we will call a vacuum bath a part of a vacuum table - a steel container, inside of which the workpieces to be coated are located, and from which air is pumped out. By working dimensions (dimensions) of a vacuum bath we mean it useful volume, measured by internal dimensions. We will agree to call the vacuum table the entire structure as a whole, consisting of a vacuum bath, an upper (movable) pressure frame, clamps and other smaller elements.
External and working dimensions of the vacuum bath.
Let's consider general principles choosing the size of the vacuum bath, we will designate specific numbers for our press.
The longer the vacuum bath, the more workpieces can be placed in it, or a larger workpiece can be veneered. On the other hand, the longer the bath, the more film has to be consumed in one working cycle, the larger the dimensions of the machine, which entails a greater consumption of room space. Need to find optimal size. As experience has shown, the optimal working length of a vacuum bath intended for the manufacture of standard furniture facades and decorative door trims, we can consider the value to be from 2.4 to 2.6 m. We will make a vacuum bath 2500 mm long, the working length of which will be 2500 - 40 x 2 = 2420 mm (40 mm is the width of the short wall profile pipe).
The width of the bath is directly related to the width of the PVC film used. Depending on the film manufacturer, there may be different meanings width, the most common is 1.4 m, which is what we will focus on. Let's choose the width of the bathtub to be 1400 mm, the working width will be 1400 - 40 x 2 = 1320 mm. When facing tall workpieces, for example, for curved (radius) facades, the width of the bathtub must be reduced (made smaller than the width of the film), but to work with such workpieces a press of a different design is needed, so these issues will not be considered.
The working height of the bath should be calculated based on the requirement that there be a small free space between the upper surface of the facades and the covering film. In other words, the film stretched over the workpieces should not touch them before air is pumped out. The calculation is as follows. First, the vacuum (breathable) table top that will be placed first on the vacuum table will be made of MDF boards 10 mm thick. Secondly, the linings for the facade blanks will be small pieces of MDF board 16 mm thick (this is the simplest, most common and best option linings). Thirdly, the thickness of the veneered blanks will range from 8-10 mm (door linings) to 16-32 mm (facades and other furniture elements). Fourthly, the sealing rubber will add about 2 mm to the depth of the bath. Eventually, maximum height the total “pie” inside the bathtub will be equal to: 10 + 16 + 32 = 58 mm. To make a vacuum bath, we will use a profile pipe with a cross-section of 60x40 mm, placing it on the short side. At the same time, the height of the free space will be no less than: 60 + 2 - 58 = 4 mm, which is quite enough.
Making a vacuum table.
Vacuum bath.
The bottom of the vacuum bath will be a sheet of steel 2 mm thick. To minimize sheet deflections under the influence of negative internal pressure, and giving the table surface an even shape (close to an ideal plane), it is necessary to make a rigid frame. To make the frame we will use the same profile pipe 60x40x2. The pre-cut pipe, in accordance with the design, is laid on the slipway, rigidly fixed with clamps, and all connections are welded. After making the stiffening frame, a steel sheet is welded on top of it. This is the most critical stage welding work, it requires a continuous weld to be hermetically sealed (double penetration is recommended).
To avoid warping of the sheet under the influence of prolonged high temperatures, you can use the following alternative method welding the sheet to the stiffening frame. Before installation steel sheet on the stiffening frame, along its perimeter, it is necessary to apply a sealing compound that can withstand high temperatures(for example, silicone high-temperature sealant), and welding is carried out not with a continuous seam, but with small regular fixing tacks with a pitch of about 50 mm. This method It is designed that short-term, local effects of welding will not be able to damage (burn out) the entire sealant, but only a small part of it in the immediate vicinity of the tacks, while most of the sealant after curing will perform its direct function.
Vacuum table dimensions.
Detailing of the stiffening frame and the procedure for assembling the vacuum bath: the stiffening frame is welded, a steel sheet is welded to it, a stationary (lower) frame with a part of the hinge joint for attaching the lifting (upper) frame is hermetically welded along the perimeter of the steel sheet.
Photo of the vacuum table from below.
The stiffening frame is made partly from an angle profile.
Lifting (pressing,top)frame.
Frame material - profile pipe 60x40x2 mm. The dimensions of the pressure frame must be exactly the same as those of the vacuum bath. If it was not possible to find a sufficiently even (not bent, not twisted) profile, then it is necessary to pre-select in pairs several of the smoothest rods from which the parts of the vacuum table will be made tightly adjacent to each other.
The clamp frame will rise thanks to adjustable hinge joints. The adjustment of the hinges is carried out after gluing the seal - strips of sheet rubber of medium hardness, about 2 mm thick.
Welded washers are needed to increase the friction area. The hinge pin is a D12 steel rod with threaded ends.
To hold the clamping frame in a raised state, gas lifts can be used. For safety reasons, it is recommended to install four gas lifts (two per side) and ensure that any three of them can support the frame. If the opening angle of the frame (45°) turns out to be insufficient, the frame will cause significant inconvenience in operation; it can be raised as high as possible at an angle of slightly more than 90°, using the thermal module parked behind as a support (gas lifts are not used).
Clamps.
To securely and tightly hold the film during vacuum pressing, it is necessary to firmly and evenly press the upper frame to the perimeter of the vacuum bath, achieving an overall fit rubber seal. For these purposes, you can use various ready-made clamps, or make them yourself.
For the manufacture of homemade clamps working on the eccentric principle, you will need the following rolled steel: half a meter of DN50 pipe (external diameter about 60 mm), two meters of rod with a diameter of 10 mm, and approximately the same amount of profile pipe with a cross-section of 20x20x2 mm.
Firstly, the DN50 pipe is cut into 8 equal 60 mm sections. Each pipe section is finished with a semicircular central cutout having a width of 10-11 mm and an arc length equal to 3/4 of the length of the outer circumference of the pipe. We get 8 pieces of eccentric rotary cylinders, to which we need to weld a handle 220 mm long from a square profile 20x20 mm.
Secondly, the steel rod is cut into 16 pieces: 8 pieces 190 mm long (for studs) and 8 pieces 55 mm long (for king pins). An M12 nut (or M10 with a drilled thread) must be welded to one end of the stud so that it can rotate freely on the pivot, and an M10x50 thread must be cut at the other end.
Thirdly, to complete the manufacture of the clamp, we weld the ends of the pin (with a nut with a welded pin pre-attached to it) to inner surface eccentric rotary cylinders.
To install the clamps on the vacuum table of the press, at eight points of the table, according to the design, through holes with a diameter of 10 mm are drilled. After which, the upper holes are enlarged, giving them an oblong shape. The clamps are adjusted by installing combination nuts in Right place threads of the stud, followed by fixation with locknuts. This operation is performed on last stage manufacturing a vacuum table, after gluing the rubber seal.
Elements and dimensions of the hinge clamp.
The hooks for the clamps are made from 50x50x3 angle steel.
If it was not possible to achieve a flat table surface.
If during the welding process the sheet has undergone significant deformations beyond the limits acceptable values, then pick up a grinder and cut welds, there is no need to redo everything again. You can ensure a perfectly flat plane of the vacuum table additional measures, namely through the use of epoxy leveling compounds, which are used in the manufacture of poured floors. To do this, the vacuum table is set strictly according to the level, the required volume of the filling mass is determined (for example, by test filling with water), the bottom of the vacuum bath is cleaned of rust, and it is primed. Fill with the prepared epoxy mixture according to the manufacturer's instructions. For reasons of economy, the mixture can be diluted with some cheap filler, for example, quartz sand. To speed up the curing of the mixture after pouring, the table can be controlled from above with heat from the thermal module. It makes sense to carry out this filling leveling operation after the vacuum press is fully ready, test samples of products have been manufactured, and a decision has been made about the need to improve the geometry of the working surface.

Upon completion of the main scope of work, the vacuum table is installed on the frame (on specially provided supports) and fixed in the corners with four bolts, as shown in the figure, after which they move on to minor work: installing and adjusting the clamps, adjusting the lifting frame hinge, gluing the seal.
The metal structure is beginning to take shape as a future thermal vacuum press, but it still lacks many elements: vacuum system, thermal module, electrical control unit - which will be discussed in the following articles.
Company SOMMTEC has developed a line of perforated vacuum tables. A special feature of these tables are holes located at a distance of 10 mm over the entire area of the plate, which allows us to carry out processing at any point on the vacuum table. Open area the slabs must be covered with a continuous polymer mat to avoid loss of vacuum.
Perforated vacuum tables are manufactured in various designs. Modular tables allow you to create large area fastening.
The main advantage of perforated vacuum tables is the ability to secure workpieces complex shape without additional reconfiguration.
SOMMTEC presents to your attention five series of perforated tables. Tables are used for processing metals, wood products, plastics, glass, film, foil, and engraving work.
All tables are made of high quality aluminum, the vacuum plate design ensures high performance characteristics, as well as excellent geometric stability during long-term use, can work in wet environments when machining with coolant. The tables cannot be bent and have no internal tension, thanks to the developed channel system it is possible to limit the working surface of the table. All perforated tables are equipped with perforated mats, which allows for through processing, as well as processing parts with existing technological windows and holes.
