Products Features

1:High Generalization and Modularization:These machines are highly adaptable due to their generalization and modularization, making them suitable for a variety of production requirements.

2:High Rigidity and Precision:The grinding wheel spindle adopts a high-rigidity sleeve-type hydrostatic spindle system, providing excellent rotational accuracy and load capacity. The grinding wheel speed can reach up to 60 m/s (for special orders).

3:Two-Axis Servo Feed:The worktable (Z-axis) and wheelhead (X-axis) are driven by AC servo motors and ball screw systems. The guideways are plastic-coated with a closed multi-point lubrication system, offering excellent vibration absorption, wear resistance, and precision retention.

4:Diamond Dressing and Auto Compensation:Multiple types of diamond dressing devices are available, enabling the precise dressing of complex grinding wheel profiles with automatic compensation features.

5:Closed-Loop Control System:Equipped with an active measurement device, the machine provides full closed-loop control during grinding, ensuring high precision and consistent results.

6:Advanced CNC System:The CNC system offers a user-friendly menu interface and can control up to four axes (X, Z, U, W), meeting the requirements of grinding and dressing cycles.

7:Optional Hydraulic or CNC-Driven Center Rest:Optional CNC or hydraulic-driven automatic tracking center rests are available for processing long, slender shafts, enhancing machine versatility.

Applications

These CNC cylindrical grinding machines are widely used in large-scale production environments, particularly for grinding large shafts and cylindrical parts in industries like automotive, aerospace, energy, and heavy machinery manufacturing. The machines are ideal for high-precision grinding in the mass production of engine shafts, transmission shafts, and other large components requiring exceptional accuracy and surface quality.
