Biesse Woodworking CNC Machine Spare Parts Vacuum Suction Cup 13x75x48mm Grey

Need a 132 x 75 x 48 mm vacuum suction cup for a Biesse woodworking CNC machine? This is that cup: 132 x 75 mm top face, 48 mm height, grey, moulded in Bakelite rather than rubber, so it keeps a flat face under clamping load instead of taking a set. It is the pod the panel sits on, holding the board by vacuum with no clamps. The same series runs nine sizes on a 132 mm common width, in 29 / 48 / 74 mm heights. Customization to drawing is available.

A nesting table that loses hold mid-cut gives no warning. The panel creeps a fraction of a millimetre, the tool follows the program instead of the part, and the piece is scrap before anyone hears the change. On a Biesse machining centre the part doing that holding is the vacuum suction cup the board rests on.

This is that cup at 132*75*48 mm: 132 mm across the top face, 75 mm deep, 48 mm tall, in grey. The 132 x 75 mm top is the sealing area the panel presses on, and 48 mm is the height the board rides above the table. Both are measured on the cup.

The body is Bakelite, a thermoset phenolic plastic, not a soft elastomer: it holds its shape under clamping load and does not take a permanent set, so the face stays flat in service. The series is built on one common 132 mm width with three lengths and three heights — 146 / 75 / 54 mm by 29 / 48 / 74 mm — nine sizes, so mixed-height tables come from one range.

Fit is decided by three numbers plus the pod the cup sits on: measure the old one and compare. Customization is available where a machine has been modified. Cups are listed for Biesse woodworking CNC machines and priced on request.

What the three dimensions and the material actually control on a table:

• 132 x 75 mm top face — the sealing area the panel presses on; a cup that has spread past 75 mm depth will not sit a board flat.
• 48 mm height — sets how high the panel rides above the table, and it has to match the pod the cup seats on.
• Bakelite body — thermoset phenolic plastic; keeps a flat face through repeated clamping instead of taking a set like rubber.
• Grey moulding — this SKU ships grey; the same cup is also listed in brown for shops standardising on colour.
• Nine sizes on one width — 146 / 75 / 54 mm tops in 29 / 48 / 74 mm heights, all at 132 mm across.
• No clamps, no fixtures — the panel is held by vacuum alone, so a cut runs without clamp moves or fixture swaps at the table.
• Swap as a unit — one cup per grid position; a cracked or flattened cup is lifted off and replaced without opening the vacuum circuit.
• Customization available — length, width and height are the fields that change when a drawing differs from the stock size.
• Three-number check — length, width and height off the old cup is all that has to be measured before ordering.

What a cup that matches the pod adds to a table that has been losing grip:

• The panel stays where the program put it. A 48 mm cup standing square carries the board at one height for the whole cycle, so the tool follows the part instead of the creep.
• Scrap is caught before the cut, not after it. Checking 132 x 75 mm against a worn cup takes a caliper and a minute; a slipped panel costs the whole piece.
• One series covers a mixed table. Nine sizes on a common 132 mm width means a table with 29 / 48 / 74 mm pods is matched from one supplier rather than three.
• Thermoset, not rubber. A Bakelite face that stays flat holds vacuum across the full 132 x 75 mm area, so the pump works less for the same hold.
• No fixture change at the table. The cup seats where the old one sat, so the grid layout and the machining program stay exactly as they were.
• Repair instead of rebuild. One cup per position, swapped as a unit: the vacuum circuit, the pod and the grid are untouched by the replacement.
• Fit settled on three numbers. Length, width and height off the old cup is enough to order the right size, with no part number needed on the drawing.

It fits if the old cup measures 132 mm across the top, 75 mm deep and 48 mm tall. Measure the one on the pod and compare those three numbers; send the machine model with the enquiry and it can be confirmed before the order goes in.

Bakelite, a thermoset phenolic plastic. That is a harder material than a rubber cup: it holds its face flat under clamping load instead of taking a permanent set, and it is the reason the cup is checked on dimensions rather than on softness.

Because 48 mm is what sets how high the panel rides above the table. A cup of the wrong height lifts the board to a different reference and the whole program runs against it, even though the cup itself looks correct on the pod.

Yes — the height in the part size has to match the pod. The same series covers 29 / 48 / 74 mm heights on the 132 mm width, so a table mixing pod heights is ordered from one range rather than from different suppliers.

Yes. Customization is available on this cup, and the range is listed in both grey and brown. A change of length, width or height is made to a drawing, so send the finished dimensions rather than a name.

No — the listing is the vacuum cup itself. Sealing covers and gaskets for Biesse vacuum blocks are separate items in the same catalogue, so a pod that has lost vacuum is rebuilt from those parts plus the cup.

One per grid position you actually use. Count the populated positions on the table rather than the total on the grid: unused holes stay empty, and a spare of the same 132 x 75 x 48 mm size is the usual second line.

On request — there is no fixed list price for this size. Send the quantity, the three measurements off the old cup and the machine model, and the current price comes back with the lead time for that quantity.
