132*146*48mm Vacuum Suction Cup Vacuum Block For Biesse Woodworking CNC Machines

Vacuum blocks are the fixture on a nesting machine: the pod has to hold a panel through a full cut cycle without letting it creep. This block is 132 x 146 x 48 mm, grey, for Biesse woodworking CNC machines. Three dimensions, all measured on the block: 146 mm length, 132 mm width, 48 mm height.

When a pod loses grip mid-cut, the damage is already done. The panel creeps a fraction, the tool follows the program rather than the part, and the piece is scrap. The cause is almost always the block: a sealing face that has taken a set, a block that has been over-tightened, or a pod that no longer stands square to the table.

This is the vacuum block for that position on Biesse woodworking CNC machines. Size is 132 x 146 x 48 mm: 146 mm long, 132 mm wide, 48 mm high, in grey. The footprint decides which grid position it covers and the 48 mm height decides how high the panel is carried above the table.

A block is not a single consumable. It carries the sealing ring and the ball valve, and both of those are what actually seal and release. When a pod fails, the block is often intact and the ring or valve under it is the part that has gone; replacing the block without checking those two wastes the block.

Fit is decided by the three dimensions plus the pod it sits on: measure the old block and compare against 132 x 146 x 48 mm. Sealing rings and ball valves for Biesse pods are available in the same range, so a full pod can be rebuilt in one order rather than three.

What the footprint and the height control on a nesting table:

• 132 x 146 mm footprint — 146 mm length and 132 mm width set which grid position the block covers on the table.
• 48 mm height — the number that decides how high the panel is carried above the table surface.
• Grey block — a used block that has picked up glue and dust is still visually distinct from a new one.
• Biesse CNC fit — listed for Biesse woodworking CNC machines, seated in the vacuum grid.
• Carries the seal and the valve — the block is the body; the sealing ring and the ball valve are the parts that seal and release.
• Replaceable body — a cracked or distorted block is swapped as a unit without touching the vacuum circuit.
• Rebuild in one order — rings and valves for the same pods come from the same range, so a pod is rebuilt rather than half-replaced.
• Three-dimension fit check — length, width and height off the old block; nothing else needs measuring.
• One grid position — 146 x 132 mm matches one position on the vacuum grid; the block is not meant to be trimmed to fit another.

What a correct block adds to a pod that has been losing grip:

• The panel stays where the program put it. A 48 mm block that stands square holds the panel at one height through the cycle, so the tool follows the part rather than the error.
• Right position on the grid. A 132 x 146 mm footprint covers the grid position it was made for; a block that is close but not exact leaves part of the pod unsupported.
• Rebuild instead of replace. Because the block carries the ring and the valve, a pod is normally rebuilt with those two parts rather than having the block thrown away.
• One order, one pod. Rings and valves for the same Biesse pods are supplied from the same range, so a rebuild does not need three purchase orders.
• Visible condition. Grey block against a used one shows distortion and over-tightening marks before they become a vacuum fault.
• Fit checked on three numbers. Length, width and height off the old block is enough to order the right one.
• No fixture change. The block seats where the old one sat, so the grid layout and the machining program stay as they were.

Measure the old block: 146 mm long, 132 mm wide, 48 mm high. If those three match, it seats in the same grid position. Send the machine model if you want it confirmed first.

The listing is the vacuum block. The sealing ring and the ball valve that sit in it are separate items and are available from the same range.

48 mm sets how high the panel rides above the table. If the block is not at that height, the panel is machined at a different reference.

If the block is intact and square, check the sealing ring and the valve first. A block only needs replacing when it is cracked or distorted.

It is listed for Biesse woodworking CNC machines. On another machine, compare the footprint and height against the old block before ordering.

One per grid position in use. Count the positions on the table so the order matches the table.

The listing gives the size and colour for this block; the body material is not specified in the product data. Say so if the material matters for your table and it will be confirmed.
