Regrinding

Generally, the units have 2mm allowance for regrinding on dies and punches normally have up to 6mm regrinding allowance. This varies according to the model and material being punched so please refer to the individual model pages

The Models M10, M14, M20, M30, &  M41 utilise a ‘punch head’ design which has been the basis of our product range for four decades.

The Model No in each case represents the maximum diameter available within that unit range.

The maximum shape size available in any Model must be contained by the maximum diameter in that unit - which is the main shaft diameter.

It is a feature of each of these models that the sleeve in which the punch slides acts as the material gripper and strips the metal off the punch as it retracts with the disc spring stripping force.

Sometimes, when punching very thin material - less than 0,7mm thickness - the sleeve is counter bored and fitted with a close fitting insert to suit the punch diameter.

The punch head assembly and punches in the ‘M’ series can be interchanged with other model types of the same ‘M’ series. For example the ‘M10’ punch head also fits Model SM10, and Model M10PF.

The punch heads can also be built into ‘box jigs’ or ‘bridge beams’ for through feeding of material for repeat indexing.
