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.
1A1 400 Ceramic Centreless grinding wheel
Model：1A1
Workpiece material: grinding of shafts, rods, bearing rings, bars, ceramic materials, PCD/PCBN.
Features: Large single depth of cut, single feed of rough grinding centreless grinding wheel up to 0.2mm.
High material removal efficiency.
Good shape retention of the grinding wheel.
1A1 type grinding wheel has good shape retention and high self-sharpening. Reduced dressing.
Good machining quality - bars up to Ra0.03 and bar polishing with high precision and quality.
Specification size: 1A1 400X200X228.6X13 D140/170 V200
The coreless grinding process is basically continuous, with high productivity, good roundness and cylindricity, good uniformity in the shape of the processed workpieces, good surface degree, and is suitable for rough grinding, semi-finish grinding, finish grinding and polishing of the workpiece materials.
