BK Cup Polishing Wheel for Glass Edging and Double-Edging Machines

Quick answer: BK cup polishing wheels are used on straight-line edging and double-edging machines to refine marks left by preceding diamond grinding wheels. They provide an intermediate polishing action that prepares a smoother glass edge for the following fine-polishing stage. Confirm the machine position, wheel size, bore, grit and cooling-water direction before quotation.

What this product is used for

Intermediate glass-edge polishing on straight-line edging and double-edging machines to refine diamond-wheel marks and prepare the edge for final polishing.

Cooling-water checks for stable BK wheel polishing

A newly installed BK wheel can still leave severe edge defects when the wheel specification and machine parameters are correct. If the wheel becomes unusually hot, inspect the cooling system before changing pressure or feed. In one troubleshooting case, the water pipe had been knocked out of position during wheel replacement, so the water no longer reached the polishing surface.

Insufficient water can overheat a BK wheel within a short time. The polishing surface may burn, cutting action can fall sharply, and the heated glass edge becomes more vulnerable to deep marks and chipping. This is a process and cooling problem rather than evidence that the wheel hardness or grit is necessarily incorrect.

After restoring the water pipe and confirming an even flow across the wheel, the edge defects disappeared and wheel temperature returned to normal. Before restarting production, verify water direction, flow, wheel rotation, spindle condition and the complete grinding and polishing sequence.

Frequently Asked Questions

What is a BK polishing wheel used for?

A BK cup polishing wheel is used after diamond-wheel grinding on straight-line and double-edging machines. It refines remaining grinding marks and prepares the glass edge for the final fine-polishing stage.

Why does a BK polishing wheel need cooling water?

Cooling water controls heat, carries away grinding debris and supports stable contact. A misdirected or insufficient water supply can overheat and burn the wheel, reduce polishing action and damage the glass edge.

What grit should I choose for a BK glass polishing wheel?

Common references include 46, 60 and 80 grit. Select the grit from the depth of the preceding diamond-wheel marks, glass thickness, machine position and required finish rather than choosing grit alone.

How can I reduce marks after glass edge grinding?

Check the preceding diamond wheel, BK wheel condition, water direction and flow, spindle runout, pressure and feed. Deep marks must be corrected at the stage where they are created before final polishing.
