CNC Centerless Grinders
CNC centerless grinders are used for external cylindrical grinding of rotating parts without center support. The relative movement of the guide wheel and the grinding wheel is controlled by the CNC system to achieve geometric correction of the outer diameter of workpieces with different size ranges.

Features
Machine Coverage Expansion
The width of the grinding wheel/guide wheel has been expanded from 200 mm to 500 mm, combined with a 200 mm center height structure, extending the machining diameter range from 5–100 mm to 5–200 mm.
Micron-Level Feed
The minimum unit for guide wheel feed and grinding wheel dressing is 0.001 mm. A lead screw structure converts material removal into quantifiable micro-step control.
Geometric Error Convergence
The workpiece is not clamped or positioned. Supported by the grinding wheel, guide wheel, and support, the roundness and cylindricity results are primarily determined by the consistency between the dressing trajectory and the guide wheel movement.
Applications
Automotive Parts Machining: Used for continuous grinding of the outer diameters of cylindrical parts such as drive shafts, valve stems, and fuel injector needles, to achieve consistent outer diameter geometry in mass production.
Bearing Manufacturing: Used for machining the outer diameters of rollers and bearing rings, reducing the impact of clamping and positioning chains on cylindricity results through a clamp-free support method.
Hydraulic System Parts Machining: Used for machining the outer diameters of piston rods and valve cores, to reduce the impact of clamping deformation on the outer diameter shape in the machining of workpieces with a length-to-diameter ratio.
Precision Mechanical Parts Machining: Used for machining the outer diameters of guide pillars and optical shafts, to form stable linear motion mating contact surfaces.
