The Airlox®TM M-3 is a precision built, light production tool, operated by a special air cylinder. Remarkable air economy is obtained by limiting the maximum air travel to one inch. An easily accessible adjustment screw enables the operator to set the maximum jaw opening of two inches. Many users synchronize the vise jaw movement with operation of machine tools. This can be achieved with any three-way valve; either manual hand or foot valve, or an electric valve triggered by “M” code in CNC Machine. The vise is regularly supplied with #0 Brown & Sharpe jaw hole spacing and soft jaw faces. It can also be supplied with undrilled jaw castings for fitting to other jig faces. The Model M-3 provides a gripping force of 5 times line pressure. Airlox®TM vises—with their quick positive action and high reliability—are very well suited for todays unattended operation of “pick and place” robots.
