The Precision Internal Diameter Punch Grinder is a compact and high-accuracy grinding machine designed for internal diameter grinding, punch pin grinding, small hole grinding, mold component grinding, precision pin processing, and tool room applications. It is suitable for small precision workpieces that require stable clamping, high-speed spindle grinding, accurate feed control, and consistent inner diameter machining quality.

This ID punch grinder is widely used for processing punch pins, ejector pins, mold inserts, precision sleeves, small shafts, round tooling parts, and small cylindrical components. With multiple model options including GD-002A, GD-002K, GD-002S, and GD-002T, users can select the suitable configuration according to workpiece clamping diameter, inner diameter processing range, spindle speed, working head speed, machine size, and production requirements.

The machine supports a high-speed spindle range of 0-20000 rpm, making it suitable for precision internal grinding and fine hole finishing. The front and rear handwheel feed is 0.005 mm/div, allowing operators to control grinding depth accurately during fine machining. The grating ruler accuracy reaches 0.001 mm, supporting stable precision grinding and repeatable machining results.

Depending on the model, the working head speed ranges from 0-180 rpm to 0-500 rpm, providing flexible speed adjustment for different workpiece materials and grinding conditions. The working head rotation angle supports angular grinding, improving process flexibility for various punch, pin, and mold component applications.
