Polishing Buffing Wheel 4-005-15-0187 120mm White Cotton 19mm Hex Bore

Yes - this is the buffer ring that takes out the hazy line an edgebander leaves after the trimming station. The 4-005-15-0187 (BW005) polishing buffing wheel is 120 mm outside diameter, 10 mm thick, with a 19 mm hexagon bore that keys onto the hex drive shaft with no adapter. White cotton cloth face, iron hex centre. It is the buffing wheel for Homag edge banding machines and Brandt edgebanders. One ring per buffing spindle. MOQ 100 pcs, lead time 5-8 working days.

A dull, grey edge coming off the buffing station usually traces back to the same three things: the cotton wheel has worn flat and barely touches the banding, the bore has rounded so the ring wobbles on the shaft, and the spare on the shelf does not match the machine's bore. This ring is built against all three.

The 4-005-15-0187, model BW005, is a 120 mm cotton buffing wheel for edgebanders: 120 mm outside diameter, 19 mm hexagon bore, 10 mm face width. The 19 mm hex bore, not the diameter, is what decides fit. It keys straight onto the hex drive shaft of a Homag or Brandt buffing spindle - no adapter, no key, no grub screw.

The face is layered white cotton cloth, which holds compound in the fibres and releases it against the edge as the ring turns. The centre is an iron hex hub, pressed in, so the bore keeps its six flats instead of rounding out under load. Cotton polishes; the iron hub carries the drive.

Three numbers to check before ordering: 120 mm diameter, 19 mm hex bore, 10 mm thickness. Other diameters and other inner-hole shapes can be supplied - measure the bore shape, bore size, diameter and thickness off the old wheel and send them. MOQ 100 pcs, 5-8 working days, T/T, cardboard box.

What the hex bore, the cotton face and the three dimensions do at the station:

• Hex bore, not a round bore - a 19 mm hexagon seats on the hex drive shaft, so torque goes through six flats, not a friction fit.
• 120 mm outside diameter - the working face diameter; it sets surface speed at the edge against the spindle speed your machine runs.
• 10 mm face width - a narrow contact band, so the polish zone stays on the banding edge instead of spreading onto the panel face.
• Layered cotton cloth - the fibres hold polishing compound and release it slowly, so the banding is polished rather than cut.
• Iron hex centre - a pressed metal hub keeps the six flats square; a cotton-only bore would round out and the ring would spin on the shaft.
• White cloth - loading and metal pick-up show up on the face, so a wheel past its working life is visible before it marks edges.
• Homag and Brandt fit - listed as the buffing wheel / buffing ring for Homag edge banding machines and for Brandt edgebanders.
• Consumable, changed in minutes - one ring per buffing spindle; swap it when the face glazes and goes hard.
• Other sizes and bore shapes - supplied on request when the measured wheel is not 120 x HEX19 x 10 mm.

The choice at the buffing station is normally a part that fits, or a part that is nearly right and marks 10 mm of every edge until it is thrown away:

• A wobbling ring is usually a rounded bore. Once a cotton bore rounds out, the ring sits off-centre and lays a wavy polish line along the banding. A 19 mm iron hex centre keeps it square on the shaft.
• Polish, not removal. Cotton plus compound levels the fine scratches the trimming blades leave without taking banding material off, so the 10 mm face does not thin a 0.4 mm edge band.
• One part number, two machine brands. Homag edge banding machines and Brandt edgebanders share the hex drive, so one 120 mm ring covers both a Homag line and a Brandt cell on the same floor.
• No adapter to lose. The hex bore keys directly onto the spindle: no key, no grub screw, no bushing, and nothing to fall out during a change.
• End of life is visible. White cotton shows loading and metal pick-up, so the ring is replaced at the 10 mm face, not after it has burnt the edge.
• A machine with an odd spindle is not locked out. Other diameters and other inner-hole shapes are supplied on request; send the four measurements off the old wheel and the ring is matched to them.

Check the bore first: 19 mm hexagon. Then 120 mm diameter and 10 mm thickness. The hex bore is what decides whether the ring mounts on your buffing spindle at all.

It is the bore: a 19 mm hexagon, measured across the flats. The bore has six flats, not a round hole, so it keys onto a hex drive shaft.

Yes. The wheel is listed for Homag edge banding machines and Brandt edgebanders, and the fit is decided by the 19 mm hex bore, the 120 mm diameter and the 10 mm width.

Cotton is the finishing grade: it holds compound in the fibres and polishes the edge, where sisal is coarser and used further upstream. On a 10 mm face the cotton ring is the last thing that touches the banding.

The white face glazes, goes hard to the touch, and the edge stops coming up glossy. That is the point to change it, before the flat spot starts marking edges.

Yes. Other diameters and other inner-hole shapes can be supplied on request. Send the bore shape, bore size, diameter and thickness measured off the old wheel.

One ring per spindle. A station that runs two spindles takes two, usually ordered as a pair because they wear at the same rate.

MOQ 100 pcs, lead time 5-8 working days, payment T/T, packed in a cardboard box.

The four numbers off the old wheel - bore shape, bore size, outside diameter and thickness - plus the machine make and model so the ring can be checked against it.
