Notes: i) The figures in the above chart are given as a range, for example 0.15 - 0.20 mm
For mechanical machines choose the smaller die clearance of the range For hydraulic machines choose the larger die clearance of the range ii) For Galvatite and Zintec materials, use Mild Steel as a guide iii) The figures above are a guideline only.
