Frequently asked questions
Soft monolithic jaws Ø 500 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 machined (bored) in situ on the chuck to compensate for mounting tolerances and achieve maximum concentricity — a soft jaw machined in situ exceeds the precision of any standard hardened jaw.
Are these jaws for Ø 500 mm compatible with my chuck?
PS3/PS4 jaws are designed for 3 or 4-jaw chucks with PS-type mounting — check compatibility with your chuck before purchasing. The diameter Ø 500 mm 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 exist only in versions for internal gripping or only for external gripping — check the type before purchasing.
