180x6x28mm Woodworking Machinery Part for SCM Machine Vacuum Block Rubber Gasket

Need to re-seal a leaking SCM vacuum pod without buying a whole block? This gasket is the part that wears: 180 mm long, 28 mm wide, 6 mm thick, gray rubber, made for the SCM vacuum block seat. One gasket covers one 180 mm seat, so a flattened lip is replaced on its own. Shops running SCM CNC centres keep two or three in the drawer as wear items. Vacuum cup parts for Homag, Biesse and other machine brands are also supplied on request.

A vacuum pod stops holding a panel for one reason in most cases: the rubber seat has flattened. That single failure creates three problems on the same afternoon — a workpiece that creeps a few tenths under the cutter, a block that has to come off the machine, and a replacement quote that arrives after the part was needed, with the CNC idle in between.

This gasket is the wear part that sits in the SCM vacuum block and forms the sealing face under the panel: 180 mm long, 28 mm wide, 6 mm thick, gray rubber. Because the section touching the board is only 6 mm thick, panel edges, chips and clamp pressure reach the rubber first and the block body second. Renewing it keeps the original pod, hose and valve in service instead of replacing a block to cure a worn lip.

Fitting is a hand job on the block seat: lift out the old gasket, clear the groove of chips and glue, press the new one in along its 180 mm length. The part seats without machining, adhesive or a new clamp plate, so the pod is back on the table the same shift.

What decides whether a replacement gasket keeps a pod sealed, or leaks within a month.

• Seat-sized, not cut-to-fit — each gasket arrives at 180 × 28 × 6 mm, so it goes into the SCM block seat without trimming a strip to length.
• 6 mm section takes the abuse — chips, panel edges and clamp pressure reach the rubber before the block face does.
• One continuous 180 mm seal — no joint, no overlap and no butt gap at the corner where a leak starts.
• Gray rubber shows its age — wear, embedded chips and a flattened lip stay visible against the block without measuring.
• Compression resistance — the rubber grade is chosen for wear, tear and compression, which is the duty a pod seat actually imposes.
• Same size every batch — a 180 × 28 × 6 mm replacement seats like the one it replaces, so no re-shimming is needed.
• Hand installation — pressed into a cleaned seat with no adhesive, no fasteners and no machining.
• One gasket, one seat — each piece covers a single 180 mm seat, so one leaking station is fixed without touching the rest.
• Matched parts on request — vacuum cup accessories for Homag, Biesse and other brands come from the same source.
• A stock item, not a project — small, light and stored flat, two spares fit in a drawer beside the machine.

When a pod loses grip there are two bad options: an outside technician, or panels that move. This part is the third.

• Fix the seat, keep the block. The gasket is the only part that wears against the panel, so a 6 mm rubber strip replaces the cost of a complete vacuum block.
• Back on the table the same shift. A hand-fitted 180 mm gasket needs no machining and no adhesive, so the down time is the fitting, not the wait.
• Panels stay where they are put. A sealing face that is not flattened closes the leak path, so suction holds the sheet through the cut.
• Fewer scrapped sheets. Movement under the cutter turns a good panel into scrap; sealing the seat removes that cause at the source.
• Predictable spares stock. One size — 180 × 28 × 6 mm — covers every pod of this type on the machine, so the shelf holds one bag, not five.
• No adapter, no modification. The gasket sits in the existing seat at the existing depth, so the machine stays as it was built.
• Mixed machine parks, one supplier. With Homag and Biesse vacuum cup parts also supplied, a shop running several brands has one vendor.
• Cheap to hold, expensive to miss. A gasket small enough to store flat is worth keeping in the drawer when a pod fails before a deadline.

Check the seat against 180 × 28 × 6 mm before ordering. If the old gasket measures 180 mm long, 28 mm wide and 6 mm thick, this part replaces it directly; if any one of those numbers is different, send the size and the matching gasket can be quoted.

6 mm is the thickness, 28 mm is the width and 180 mm is the length. The product name reads length × thickness × width, which is why buyers who order from the name alone sometimes receive the wrong section — measure the seat, not the title.

No. This item is the rubber gasket only. The block, hose and valve stay on the machine; the worn seal is lifted out of the seat and the new one is pressed in.

One gasket per 180 mm block seat. Count the stations on the table, add the spare you want in the drawer, and the quantity is settled without measuring anything else.

A lip that looks flat, shiny or cut is finished, even when the part still looks whole. The usual first sign is a panel that shifts during machining or needs more vacuum than it used to.

This size is cut for the SCM vacuum block. For Homag and Biesse vacuum cups the matching parts are supplied on request, so a mixed machine park can be covered from one order.

Gray rubber. The colour is not cosmetic: gray shows embedded chips and a flattened lip against the block, which black rubber hides.

Send the size and the quantity and a quote follows. Price is on request for this item, and those two numbers are what makes an answer accurate rather than a range.
