Centerless Grinding Wheel

Features:

Centerless grinding wheel process is essentially continuous, it has efficient batch external grinding, high roundness and cylindricity of workpiece and good consistency of dimension, good surface finish after fine grinding, used for rough grinding, semi-fine grinding and fine grinding.

Application:

Mainly used for grinding carbide rod, ceramics material, magnetic material, stainless

steel bar, PCD and PCBN, etc.

Industrial applications of centerless grinding for surface finishing are listed below:

• Automotive industry: piston pins, drive shafts, wheel hubs, gear shafts, steering columns, engine valve parts.
  

• Aerospace industry: fasteners, hydraulic components, wing blades, fuel components, compressor disks, etc.

• Medical devices: implantable rods, stents, tubing, surgical pins, orthopedic pins, bone screws, etc.
  

• Manufacturing and metal fabrication: spindles, tool holders, rollers, cutting tools, conveyor rollers, locating pins, etc.
