150x19x20mm Buffing Wheel Polishing Cotton Wheel White 19mm Hex Bore

A replacement buffing wheel for the polishing station of a CNC edgebander comes down to three numbers: 150 mm outside diameter, 19 mm hexagon bore and 20 mm face width. This cotton wheel carries all three. The body is layered white cotton on a metal hub, so it seats on the six flats of the spindle and buffs the trimmed edge line without riding onto the panel faces. Other diameters, face widths and inner-hole shapes are made to order.

A shop running a CNC edgebander meets the same three things on the polishing station. The buffing wheel wears down to a bare hub, so the trimmed edge leaves the line dull and hazy. A replacement bought by diameter alone turns out to have a round bore and will not sit on a hexagon spindle. And a wheel that is too wide rides over the edge line and marks the panel faces either side.

The 150xHEXx19x20 is the part for that station: a layered cotton buffing wheel, white, 150 mm across the outside, 20 mm wide on the face, with a 19 mm hexagon bore cut through a metal hub. Cotton does the buffing; the metal hub keeps the bore six-sided, so the drive is carried on six flats.

It mounts on the polishing spindle of a CNC edgebanding machine, behind the trimming unit. The trimmed edge runs past the white cotton face and comes off with the glue line buffed back and gloss left on the banding. The 20 mm face is narrow enough to work the edge line only, which is why the part is also sold under edge banding machine spare parts and edge banding machine accessories.

Wheels are packed one per carton box and ship from Guangdong, China, so a spare can live on the shelf next to the machine.

What you get, in the three numbers that matter on the spindle:

• 150 mm outside diameter — matches the polishing station of common CNC edgebanders, so a worn original wheel comes off and this one goes on.
• 19 mm hexagon bore — the hole is six-sided and cut through a metal hub, so torque is taken on six flats, not on friction.
• 20 mm face width — narrow enough to work the trimmed edge line only, without riding up onto the panel faces above and below.
• White cotton body — layered cotton cloth in white, the grade used for buffing out a glue line and leaving gloss on the banding.
• Metal hub insert — the bore sits in metal, not cotton, so the six flats stay true and the hole does not wear loose.
• For CNC edgebanding machines — listed as a woodworking machine spare part for the polishing station behind the trimming unit.
• For PVC, ABS and veneer edges — the same 150 mm face buffs the glue line on plastic banding and on veneer.
• Other sizes on request — 150x19x20 mm is the stocked size; other diameters, face widths and inner-hole shapes are made to order.
• Carton box packing — each wheel is boxed, so a spare waits on the shelf with its cotton face clean instead of picking up bench grit.

On most edgebanders the polishing station is treated as an afterthought: any wheel of the right diameter is expected to do. The three numbers on this part say otherwise.

• Fits the bore, not just the diameter. A 19 mm hexagon bore in a metal hub lets the wheel seat on the spindle flats, so the drive does not slip and the bore does not wear round.
• Works the edge line only. The 20 mm face reaches the glue line and the banding and stops short of the panel faces, so a fresh wheel does not mark a surface that is already finished.
• A spare on the shelf, not an order in transit. At 150 mm x 19 mm x 20 mm a second and third wheel sit in their cartons, and a changeover costs one machine stop.
• Same finish from the first panel to the last. One cotton grade and one 150 mm face on every wheel, so the gloss on the edge does not step when a wheel is replaced mid-batch.
• A size change without a supplier change. If your machine takes a wider face or a round bore, the same line covers it: send the diameter, the bore and the width you need.
• Spare-part logic, not consumable guesswork. The part is ordered by size, so the wheel in the next carton matches the wheel on the shelf.

150 mm is the outside diameter, 19 mm is the hexagon bore and 20 mm is the face width. All three have to match the polishing spindle. A wheel that matches the diameter but not the bore will not seat on it.

It fits an edgebander whose polishing spindle takes a 150 mm wheel with a 19 mm hexagon bore and a 20 mm face. Measure the bore of the old wheel with a caliper before ordering, and check that it has six flats, not a round hole.

Hexagon. The bore is 19 mm across the six flats and is cut through a metal hub, so the wheel is driven on the flats of the spindle rather than on friction.

Yes. 150x19x20 mm is the stocked size; other diameters, face widths and inner-hole shapes are made to order. Send the three numbers your machine needs and the quantity.

Cotton cloth with a metal hub, in white. The cotton does the buffing and the metal holds the hexagon bore in shape under drive.

Wood, veneer and plastic edge banding, PVC and ABS included. It is specified as a woodworking machinery tool for the polishing station of an edge banding machine.

Slide it onto the polishing spindle, seat it against the hub, and check that it runs true before a panel is fed. Do not run it against an edge until it is fully seated.

Keep them in the carton box, off the bench, until they are used. Cotton picks up grit and metal swarf, and a contaminated face scratches the edge instead of polishing it.

It is made in Guangdong, China, and packed one wheel per carton box. Send us the quantity you need and we will quote against it.
