An upgrade to linear scales eliminated motion errors and improved the accuracy of a vertical machining center at Votaw Precision Technologies. Votaw Precision Technologies in Santa Fe Springs, Calif., ...

Optical or magnetic linear encoders handle high-res needs in dirty jobs. Linear encoders help minimize errors in motion transmission such as backlash, hysteresis, abbe errors, ball-screw thermal ...

A typical linear encoder consists of a scanning unit and a scale. The scale is generally glass and is cemented to a support, usually an aluminum extrusion. The scanning unit contains a light source, ...
