Advanced Features, Effortless Operation

The design philosophy behind our CNC Cylindrical Grinder is to integrate advanced, high-performance capabilities with a highly rigid and precision-engineered machine structure, delivering high efficiency, easy operation, and automated performance.

Advanced Features, Effortless Operation

Smart Operation

Robust and stable machine structure ensures excellent machining stability.

The grinding wheel spindle adopts a combination of hydrostatic and hydrodynamic bearings,providing enhanced rigidity and low vibration.

The worktable features hydrodynamic guideways for smooth and stable movement.

The X and Z axes are driven by servo motors, with the X-axis equipped with a full closed-loop optical linear encoder.

Both straight-infeed and angular-infeed models are available.

A variety of optional automation equipment is available to meet customer requirements and achieve automated grinding operations.

Smart Operation

High-Rigidity Workhead: Equipped with 10 precision angular-contact ball bearings, providing excellent resistance to heavy axial and radial loads.

Tailstock: Constructed from high-grade Meehanite cast iron, featuring a robust structure with high rigidity and stability.

Tailstock Quill: Manufactured from alloy steel and hardened for superior wear resistance and durability.

Grinding Wheel Spindle: Features a combination of hydrostatic and hydrodynamic bearings.

The bearings are supported by a high-pressure oil film, eliminating metal-to-metal contact and friction. This unique spindle design provides not only high rigidity but also excellent vibration resistance.
