For many years now a source for some of the smallest and cheapest home made CNC mechanisms has been the seemingly never-ending supply of surplus CD and DVD-ROM drives. The linear actuator that move… ...

BELT DRIVES Belt-driven actuators, in contrast, are optimized for high speeds. They are limited in length only by the actuator profile itself, or about 3 3 that of equivalent ball-screw actuators.

There is, however, one type of actuator that is vastly underutilized. Linear actuators aren’t ‘maker’ friendly, and building a customized linear actuator is an exercise in pain.

The TRS actuators ensure high accuracy along the length of travel, with a choice of either a roller screw, offering ± 0.0102 mm/300 mm, or a ball screw, providing ± 0.100 mm/300 mm. The linear stages ...

Previously, the realization of ascending and descending stairs and landing pattern modification control by WL-16RII were reported. However, it is difficult to use the landing pattern modification ...

Abstract: In order to improve the current precision of machining, a hydraulic micro-feed actuator for precision turning used in lathe or conventional CNC turning centers is introduced and the design ...
