Resin Bond Diamond Cup Grinding Wheels for Carbide Tools

Products / Diamond & CBN Tools / Diamond Grinding Wheels

Product Overview

The cup profile provides a recessed metal body and a continuous diamond rim for face, edge and tool-grinding access. The listed configurations use a resin-bond sintered diamond layer. Final grit, concentration, bond specification, dimensional tolerance, balance and maximum operating speed must be confirmed for the workpiece, spindle and grinding process before production.

Typical Applications

Safety and selection note: do not install this wheel on a handheld grinder or any other machine until the final wheel specification, mounting interface and maximum operating speed have been confirmed for that machine. Diamond is normally selected for carbide and other suitable hard non-ferrous materials; use CBN for hardened ferrous materials unless the application has been specifically reviewed.

How to Select Resin Bond Diamond Cup Grinding Wheels

Select the wheel from the workpiece, grinding operation and machine—not diameter alone. Confirm the approved drawing and maximum operating speed before production or installation.

Decision factor	Selection guidance
Workpiece material	Use diamond for cemented carbide and suitable hard, brittle non-ferrous materials. For hardened ferrous materials, evaluate CBN instead.
Grinding goal	State whether the priority is stock removal, edge quality, form holding or final surface finish; this determines the grit and bond review.
Wheel geometry	Match D, T, H, W and X to the spindle, guard, tool access and approved machine envelope. Use a straight or dish wheel when the cup profile does not provide suitable access.
Process conditions	Confirm spindle speed, wet or dry operation, coolant, feed, contact area and dressing method before the final specification is released.
Application limit	Do not use an unconfirmed made-to-order wheel on a handheld grinder. Operating speed, mounting interface, balance and runout must match the approved drawing.
