Centerless grinding is a precision machining process that removes material from a workpiece without using centers or chucks to hold it. Instead, the workpiece is supported by a work rest blade and rotated between a grinding wheel and a regulating wheel.
Here are some essential centerless grinder accessories and components:
1. Grinding Wheels
– Abrasive Type: Aluminum oxide, silicon carbide, CBN (cubic boron nitride), or diamond.
– Grit Size & Bond: Varies based on material (e.g., fine grit for finishing, coarse for roughing).
– Dressing Tools: Used to true and shape the grinding wheel.
2. Regulating (Control) Wheels
– Made of rubber-bonded abrasives or vitrified materials.
– Controls workpiece rotation speed and feed rate.
– Different hardness grades available for optimal performance.

3. Work Rest Blades
– Supports the workpiece during grinding.
– Materials: High-speed steel (HSS), tungsten carbide, or ceramic.
– Must be properly aligned to prevent taper or chatter.
4. Coolant Systems & Nozzles
– Essential for heat dissipation and lubrication.
– Prevents thermal damage to workpieces and wheels.
5. Dressing Tools & Dressers
– Single-point diamond dressers or rotary diamond dressers.
– Used to maintain wheel shape and sharpness.
6. Feed Systems (For Through-Feed & In-Feed Grinding)
– Automatic feeders for consistent part feeding in through-feed grinding.
– End stops and guides for in-feed grinding of tapered parts.
7. Gauging Systems (For Precision Control)
– In-process gauges monitor workpiece diameter in real-time.
– Post-process gauges verify final dimensions.
8. Wheel Adapters & Flanges
– Securely mount grinding and regulating wheels to spindles.
9. Workpiece Guides & Steadies
– Ensures proper alignment in through-feed operations.
10. Machine Guards & Safety Accessories
– Protects operators from debris and coolant splash.
