SMW Autoblok introduces the hybrid COMOT-AZ quick change collet chuck featuring industry standard diameter capacities of 42 mm, 65 mm, and 100 mm to accommodate a large variety of workpiece sizes. Ideal for bar and tubular stock machining that requires multiple changeovers daily, COMOT-AZ can be used in three ways: for OD machining using standard collets, for greater accuracy utilizing high precision collets with COMOT-AZ/PA or, transform COMOT-AZ quickly into an expanding mandrel for ID clamping using the EMX series.

Effectively used for hard turning, gear grinding, drilling, milling and more, COMOT-AZ provides low deformation clamping of thin-walled workpieces and offers a large selection of standard collets available in round, square, hexagonal, and special configurations when needed for virtually all sizes of spindles.

The optional COMOT-AZ/PA enables users to change from a standard collet to a high precision collet for holding workpieces from 3 mm to 100 mm with superior accuracy and repeatability. The EMX series extension mandrel is also available for internal workpiece fixturing.

For automated loading, COMOT-AZ also provides air sensing to ensure that the part is seated properly before the machine cycle starts. Other advantages include radial fine adjustment and a case-hardened body and internal parts for high resistance and longer life.
