High Precision Horizontal CNC Internal Grinding Machine with Max.ID 500mm

● Grinding Diameter Range:6-320mm
● Grinding Accuracy:Ra 0.32µm

Product advantages

This machine is a two-axis CNC internal grinding machine designed for precision grinding of inner diameters, step holes, internal end faces, and external end faces. The grinding cycle is fully automated, integrating feed, withdrawal, rough grinding, and fine grinding into a continuous process.

The system supports automatic grinding wheel dressing and real-time compensation, ensuring consistent machining accuracy and stable surface quality throughout operation.

The machine structure features a fixed workpiece headstock with a reciprocating worktable. The grinding wheel head performs longitudinal feed motion. Both the worktable and grinding wheel movements are driven by servo motors through precision ball screws and guided by linear guideways, delivering high positioning accuracy and smooth motion control.

The rotational speeds of the workpiece spindle and grinding wheel spindle are controlled by frequency converters, enabling stepless speed regulation to match different machining requirements.

The machine is equipped with a front-mounted movable control panel and an independent electrical cabinet. The enclosure structure is available in enclosed configurations to support safe and stable operation.
