Frequently asked questions
Soft monolithic jaws Ø 160 mm — when are they used instead of hardened jaws?
Soft jaws (made of unhardened mild steel) are used when the workpiece cannot be scratched or deformed by the jaw — finished surfaces, soft materials (aluminum, copper, plastic), thin-walled workpieces. Before use, soft jaws must be turned (bored) in situ on the chuck to compensate for mounting tolerances and obtain maximum concentricity — a soft jaw turned in situ surpasses any standard hardened jaw in precision.
Are these Ø 160 mm jaws compatible with my chuck?
PS3/PS4 jaws are designed for 3 or 4-jaw chucks with PS type mounting — verify compatibility with your chuck before purchase. The Ø 160 mm diameter indicates the chuck size for which the jaws are designed. Also, check the number of mounting bolts on your chuck.
Can monolithic jaws be reversed for external gripping?
No — monolithic jaws are not reversible. For external gripping (clamping from the outside of the workpiece), reversible top jaws from the TJ or DTJ series are needed. Monolithic jaws only exist in versions for internal gripping or only for external gripping — verify the type before purchase.
