150*55*20mm Cotton Polishing Wheels For Biesse Edgebanding Machine Buffing Wheel

The buffing wheel is the last thing that touches an edge before it leaves the machine, so a glazed cotton wheel is why a clean cut still looks dull. The BW004 is a 150 mm diameter cotton cloth polishing wheel, 55 mm bore, 20 mm wide, in white cotton, for CNC edge banding machines. Cotton builds a polish instead of cutting, which is what a buffing station is for.

An edge that has been trimmed and scraped is not finished. It still carries the fine scratches the trimming blades leave, and on a dark or high-gloss banding those show as a dull grey line under a light. The buffing station is where that line comes out, and the cotton wheel is the part doing the work.

The BW004 is that wheel: 150 mm outside diameter, 55 mm bore, 20 mm wide, in white cotton cloth, for CNC edge banding machines. The 150 mm diameter sets the surface speed at the edge, the 20 mm face is the contact width, and the 55 mm bore mounts on the buffing spindle on your machine.

Cotton rather than a harder compound is the point. Cotton holds compound in its fibres and releases it slowly while the wheel turns, so the edge is polished rather than cut. That is also why the wheel wears to a shape: the working face becomes the profile of the edge, which is the condition that makes a buffing station work.

Two things decide fit: the 55 mm bore and the 20 mm width. Other sizes and other inner-hole shapes can be supplied, so a machine that runs a different spindle diameter is not locked out of this grade of wheel. Send the bore, the diameter and the width you measure off the old wheel.

What the three dimensions and the cotton build do at the buffing station:

• Cotton cloth face — the fibres hold polishing compound and release it as the wheel turns, so the edge is polished rather than cut.
• 150 mm diameter — sets the surface speed at the edge; it is the number that has to match the spindle speed your machine runs.
• 55 mm bore — mounts on the buffing spindle; the bore, not the diameter, is the number that decides whether the wheel fits at all.
• 20 mm face width — the contact width against the banding, which is what defines the polish zone along the edge.
• White cotton — shows compound loading and metal pick-up, so a wheel that is past its working life is visible.
• Wears to the edge profile — the face takes the shape of the edge it polishes, which is what a buffing station relies on.
• CNC edge banding machine fit — listed for CNC edge banding machines, mounted on the buffing spindle.
• Other sizes and bore shapes — available on request when the measured wheel is not 150 x 55 x 20 mm.

What a fresh cotton wheel does that compound alone cannot:

• The dull line comes out. Trimming leaves fine scratches on the edge; a 150 mm cotton wheel loaded with compound polishes them out instead of leaving a grey line along every panel.
• Polish, not removal. Cotton holds compound and releases it slowly, so the wheel levels the surface without taking material off the banding the way an abrasive would.
• Contact width stays known. A 20 mm face gives a defined polish zone; a narrower wheel polishes part of the edge and leaves the rest dull.
• Visible wear. White cotton shows loading and metal pick-up, so a wheel that has stopped cutting is replaced before it starts marking edges.
• Bore before diameter. 55 mm is the number that decides fit on the spindle; check it first and the rest of the wheel can be matched afterwards.
• Non-standard spindles covered. Other diameters, widths and inner-hole shapes can be supplied, so a machine with an odd spindle does not need a second supplier.
• Last station, not first. A 150 mm cotton wheel runs against an edge that has already been cut and scraped, so it polishes what is there rather than correcting a bad trim upstream.

Check the bore first: 55 mm. Then the diameter (150 mm) and width (20 mm). The bore is what decides whether the wheel mounts on your buffing spindle at all.

At a buffing station the edge has already been cut; the job is to polish, not to remove material. Cotton holds compound and releases it slowly, which polishes without changing the edge profile.

The white face loads up with compound and metal, the edge stops coming up glossy, and the wheel stops holding its shape against the edge.

The listing is for the cotton polishing wheel. Compound is a separate consumable and is applied at the station.

Other sizes and other inner-hole shapes can be supplied. Send the bore, diameter and width measured off the old wheel.

The wheel is listed for CNC edge banding machines and the fit is decided by bore, diameter and width, so the same size can be used wherever those three numbers match.

One wheel per spindle. Stations that run two spindles take two, usually as a pair, because they wear at the same rate.
