Precision Outer Diameter Punch Grinder for Punch Pins and Small Shaft Grinding
The Precision Outer Diameter Punch Grinder is a compact and accurate grinding machine designed for punch pin grinding, outer diameter grinding, small shaft grinding, precision mold component grinding, cylindrical part finishing, and tool room applications. It is suitable for processing small round workpieces that require stable rotation, accurate feed control, smooth surface quality, and reliable dimensional consistency.
This outer diameter punch grinder is widely used for grinding punch pins, ejector pins, small shafts, mold inserts, precision pins, round tooling parts, and small cylindrical components. With multiple model options including GD-001A, GD-001K, GD-001S, and GD-001T, users can select suitable configurations according to workpiece diameter, machining range, table stroke, spindle speed, and production requirements.
The machine provides precise front and rear handwheel feed with 0.005 mm/div, helping operators control grinding depth accurately during fine finishing. The grating ruler accuracy reaches 0.001 mm, supporting high-precision grinding and repeatable machining results.
Depending on the model, the working head speed ranges from fixed-speed operation to variable-speed control, allowing flexible adaptation to different workpiece materials and grinding conditions. The working head rotation angle supports angled grinding, making the machine suitable for various punch and pin grinding tasks.
