Maprox AIR is fully automation system compatible. A rotary pneumatic feed supports flexible mounting options and adjustable clamping force. With 8 mm of jaw travel, the chuck opens pneumatically against spring force. The spring on the top cover can be pre-tensioned to match application requirements. Repeatable inner or outer clamping can be achieved with changeover times of less than 1 minute.

At 160 mm diameter and with an ultra-low chuck body height of just 60 mm, the chuck occupies minimal space within any automation or robot-loading system. Maprox AIR has a flexible clamping range with the top jaw or pin jaw to suit the application. Interface compatibility is supported with shanks, intermediate plates or adapters. Further sizes will be available in the near future

“Jaws for this new chuck can be made of steel, coated or plain aluminium, plastic and so on, to match the component being held,” states Leader Chuck International’s managing director Mark Jones.

Designed to keep weight to a minimum, the ER collet holders are manufactured from ALTEF-coated aluminium and weigh less than 1 kg. In application, the user can choose to pneumatically control the ER collet holder laterally or from below. The central rotary feed-through on the bottom supports full rotation of, for example, turntables or indexing units.

Clamping pressure applied to the low-height ER16 or ER20 collets is pneumatically adjustable, while the specialised coating provided a hard surface that is abrasion and scratch resistant.
