The small punch grinder can be used for grinding extremely small punch needles from as small as 00.5K10L, suitable for grinding up to a maximum diameter of 100. For workpieces with diameters above, PGA is more suitable.

When the outer diameter of the punch is small, appropriate pressure adjustment must be made on the pressure adjustment screw on the pressure arm to prevent deformation of the punch.

This tool has an accuracy within 0.003mm.
