Main Application Scope
Diamond centerless grinding wheels fit non-ferrous hard brittle materials: ceramic, tungsten carbide, sapphire.
CBN centerless grinding wheels are ideal for ferrous hard alloy workpieces: high-speed steel, bearing steel, heat-treated alloy steel.
Widely applied industries: precision ceramic, LED substrate, PCB micro drill bits, superhard cutting tools, medical pin shafts, mold round bars.
Core Product Feature
- High precision, high efficiency & high-volume mass production for cylindrical bars
Stable geometric tolerance during continuous high-speed grinding, consistent surface roughness, greatly improving daily output for automatic centerless grinders. - Two optional bond systems for different materials
Metal bond: For magnetic iron oxide material centerless grinding, strong grit retention, ultra-long service life.
Resin bond: For precision ceramic, high-speed steel, TC tungsten carbide, good self-sharpening, low workpiece burn risk.
- Complete standard size series & customizable thickness
Standard outer diameters: 12”(300mm),14”(350mm),16”(400mm),18”(450mm),20”(500mm),24”. Wheel thickness can be customized as customer’s machining requirements. - Matched rubber control wheel available
Can be used together with rubber regulating wheel to optimize roundness, straightness and dimensional stability of finished bars.

Product Value & Custom Service
Anchor diamond & CBN centerless grinding wheels solve three core pain points of bar manufacturers: frequent wheel replacement, unstable dimensional tolerance and low surface finish. Long abrasive service life cuts consumable cost, while consistent grinding performance reduces defective rate for mass production.
We support full customization of outer diameter, thickness, bore, grit, abrasive layer thickness and profile shape. Contact our sales team for drawings and quotation for special centerless grinder models.
