Carr Lane’s air rest buttons enable the use of pneumatic position control to detect proper workpiece loading in a machining fixture. These modular units consist of a threaded body installed in a fixture, which holds a precision floating plunger. The plunger has a reamed hole available in a choice of three diameters, which accepts any height of Carr Lane’s standard press-fit type rest buttons. Proper placement of a workpiece on the air rest button assembly causes the plunger to fully retract into the body. This seals off air flow, which increases the overall pressure of the system. This pressure value can be read using an analog or digital pressure sensor which can then be tied into a PLC or control system.

    A non-woven porous material with a special coating enables vacuum chucks and tables to hold sheets of metal and other materials more effectively on CNC routing machines. The material, called Vilmill, is used as a substrate between the sheet or plate material to be machined and a suitable vacuum table or vacuum chuck where it is held securely in place by the vacuum.
