Precision Internal Diameter Punch Grinder for Mold Components and
Small Hole Grinding
Product Overview
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.
