High Precision CNC Centerless Grinding Machine

A High Precision CNC Centerless Grinding Machine is a CNC device that achieves clamp-free external cylindrical grinding of workpieces through three-point support of the grinding wheel, guide wheel, and bracket.

Reduced Equipment Redundancy

The same machine tool, with a diameter range of 5–200 mm and a fixed center height structure, allows for the machining of cylindrical parts of different specifications without changing equipment.

Quantifiable Dimensional Adjustment

0.001 mm feed and dressing units correspond to the minimum displacement of the leadscrew, transforming dimensional correction from "trial adjustment" to "input control in micrometers."

Reduced Sources of Machining Errors

Without a chuck or center clamping structure, roundness of 0.001 mm and cylindricity of 0.0018 mm are primarily determined by the dressing trajectory of the grinding wheel and the geometric relationship of the guide wheel's motion.

Automotive Parts Machining: Used for machining the outer diameters of cylindrical parts such as drive shafts, valve stems, and fuel injector needles. In mass production, it reduces the impact of clamping and positioning chains on the outer diameter shape.

Bearing Manufacturing: Used for machining the outer diameters of rollers and bearing rings. In continuous feed conditions, it controls the source of cylindricity errors.

Hydraulic System Parts Machining: Used for machining the outer diameters of piston rods and valve cores. In workpieces with a length-to-diameter ratio, it reduces the impact of clamping deformation on the outer diameter geometry.

Precision Mechanical Parts Machining: Used for machining the outer diameters of guide pillars and optical shafts. In sliding or guiding fits, it forms a consistent outer diameter contact datum surface.
