New Linear Axis LIRAX-M With Direct Linear Actuation
Description
SCHUNK introduces a new series linear axis, LIRAX-M LD, designed for assembly automation and for handling weights up to 20kg (45 lb.). The LIRAX-M-LD is constructed out of a drown drawn aluminum profile that has integrated roller guides and is actuated by an efficient linear motor. The lightweight profile gives the LIRAX-M-LD a standard stroke length of up to 2,000mm.
The LIRAX-M-LD axis modules are available in two different designs. The user can choose between a signal-drive slide with feed forces of 50 N (11 lbf) to 300 N (68 lbf), or a twin-drive slide which will double the feed force to 100 N (22 lbf) and 600 N (136 lbf) correspondingly. With the linear motor and roller guides, the LIRAX-M-LD provides for impressive acceleration of 70 m/s2 (230 ft/s2) which is seven times the acceleration of gravity and speeds of up to 5 m/s (16 ft/s). With this high acceleration and speed, the LIRAX-M-LD axis is able to hold a repeat accuracy of £ 0.01mm (.0004”).
Many applications formerly actuated by a rotating cam are now being designed and equipped with the superior technology of the linear motor like that in the LIRAX-M-LD modules. With the high speeds and accelerations of the LIRAX-M-LD has almost no wear, resulting in the longest possible service life.
