PML line of high precision pneumatic chucks for the metal machining industry, for which it currently provides R&D, worldwide marketing and repair services. The PML chucks are considered, to date, as auxiliary equipment designed to solve technical gripping problems rather than being an ordinary attachment to a metal working machine. These chucks are most helpful while chucking non-standard and complicated precise work pieces, as well as for second operation of mass production and fine finishing cut-operations. These chucks are suitable for high speed turning, accurate milling, precise grindings, special models for rotary tables, measuring and quality control chucks and many more applications.

Advantages of the PML Air Chucks
• Universality
• Repeatability
• Interchangeability
• High accuracy and non-deforming
• Reliability that saves production
• Ability to chuck non-round components 
• High pressure center cooling possible
• Versatility for clamping jaws
• Lifetime reliability
• Compact structures
• Economical application to increase machine tool
