Successful production of broaching mandrels is based on experience in tool design and calculation, selection of suitable cutting material, heat treatment and precision grinding of teeth and profile. We manufacture and sharpen mandrels up to a length of approx. 800 mm (1,200 in) and can be rotary, flat or profile. We also perform sharpening of rotary and flat mandrels, regrinding or resharpening to a different profile. We grind on a CNC grinder with cooling and precise measurement of pitches and diameters.
We produce stretching and extrusion mandrels:
for fine grooving
for pen grooves

On the basis of your request, we will design, offer and manufacture a suitable tool, which we will also sharpen after wear.
