EB004 20x12x2mm Scraping Blade Inserts for CEHISA / SCM CNC Edge Banding Machine

Need the glue-line inserts for a CEHISA, SCM or Brandt edge bander? The EB004 is a 20 x 12 x 2 mm scraping blade insert that drops into the scraper seat and takes the glue line off the panel edge. 20 mm long, 12 mm wide, 2 mm thick, 4 mm inner hole. Three radius versions are available: R1.5, R2 and R3. One insert is one scraper position, so the order is a measure-and-count job rather than a part-number hunt.

A scraper station goes off before anyone calls it a fault. The edge starts coming out with a faint glue shadow, then a drag mark, then a burr along the top radius. Most shops then chase the trimming cutters, which are fine, and leave the scraper inserts in place another month, because a used 2 mm insert looks like a sharp one on the bench.

The EB004 is the insert that goes into that seat: a 20 x 12 x 2 mm scraping blade for CEHISA, SCM and Brandt CNC edge banding machines. 20 mm runs the length of the blade, 12 mm is the depth that sits in the holder, and 2 mm is the thickness that forms the scraping edge. The 4 mm inner hole is the locating point, so the insert can only be seated one way.

Three radius versions are available, R1.5, R2 and R3, and that letter decides whether the scraped edge matches the radius already machined on the panel. Ordering the wrong one does not stop the machine; it leaves a step you can feel at the edge.

The insert is a consumable, so one machine carries several and they wear as a set. Measure one used insert, read the radius off it and count the positions in the scraper unit, and the order is settled without a part-number look-up.

What the four dimensions and the radius options settle:

• 20 x 12 x 2 mm body — length, width and thickness are all taken off the insert itself; three numbers describe one part, not a size range.
• 4 mm inner hole — the insert locates on a 4 mm pin, so it seats in one orientation and cannot be fitted reversed.
• R1.5 / R2 / R3 radius — three radius versions of the same 20 x 12 x 2 mm body, matched to the radius already on the panel edge.
• Carbide insert — the scraping edge is carbide, which holds a 2 mm section at scraping contact without folding over.
• Insert, not an assembly — one 20 x 12 x 2 mm piece; holder, clamp and scraper unit stay on the machine.
• CEHISA / SCM / Brandt fit — listed for CNC edge banding machines of these three makes, at the 20 x 12 x 2 mm seat size.
• One insert, one position — a worn insert is replaced on its own without touching the others.
• Seated on the pin — release the clamp, lift the old insert out, drop the replacement on the 4 mm pin, re-clamp; no setting gauge involved.
• Ordered by two numbers — the 20 x 12 x 2 mm size plus one of R1.5, R2 or R3 is the whole specification.

What the right insert set does that a worn set does not:

• The edge stops changing mid-shift. A 2 mm insert past its life rides the glue line instead of cutting it, so the edge goes dull between two panels rather than at the start of the run.
• The radius stays the radius. R1.5, R2 and R3 are separate parts; keeping the matching version on the shelf keeps the scraped profile at the one the panel was machined to.
• No part-number research. 20 x 12 x 2 mm, a 4 mm hole and a radius letter is the complete description, all four readable off the worn insert.
• One small part, three machines. The same 20 x 12 x 2 mm insert is listed for CEHISA, SCM and Brandt banding machines, so a mixed shop stocks one insert, not three.
• Consumable, not a repair. The insert is the wear item; holder, clamp and scraper unit stay on the machine, so replacement is one 20 x 12 x 2 mm piece.
• Fitted by the operator. The 4 mm pin locates the insert and the clamp holds it, so there is no knife grinder, no gauge and no service call.
• Wear you can read. A used insert shows the glue line on its edge face, so the next change can be scheduled off the part instead of off a calendar.

Yes, if the seat takes a 20 x 12 x 2 mm insert. The EB004 is listed for CEHISA, SCM and Brandt CNC edge banding machines at that size, so the check is the old insert: 20 mm long, 12 mm wide, 2 mm thick and a 4 mm inner hole.

Yes, if those three numbers match. A 20 x 12 x 2 mm scraping insert with a 4 mm hole is the EB004; the radius letter is the only thing left to read off the old part.

The one stamped or moulded on your old insert. All three are available in the same 20 x 12 x 2 mm body, and the radius is what puts the scraped edge back on the panel's own profile.

It locates the insert on the holder pin. The hole sets the position, so the insert seats in one orientation only and the cutting edge comes out at the same height each time.

Count the positions in the scraper unit, not the panels you plan to run. Inserts wear as a set on a machine that carries several, and 20 x 12 x 2 mm inserts are consumed one position at a time.

Yes, where the seat is 20 x 12 x 2 mm. The insert is listed for CEHISA, SCM and Brandt CNC edge banding machines, so the 4 mm hole and the radius letter carry across all three.

Release the clamp and lift the old insert off its 4 mm pin. Drop the replacement on the same pin, push it down until it seats flat, and re-clamp; there is no grinding or setting step in the change.

Send the quantity, the radius version and your machine make. Price is quoted on enquiry rather than listed, and the 20 x 12 x 2 mm size plus R1.5 / R2 / R3 is all that is needed to quote.
