Embedded compact design
Integrated rail-and-screw body minimises mounting footprint, saving 30%+ envelope space versus external-guide designs.
KCH Series Embedded Screw Drive Actuator
Compact High-Precision Screw-Driven Slide
A high-precision aluminum embedded-rail slide with five body widths (KCH4 / KCH5 / KCH8 / KCH12 / KCH15), all built on a 7075-T6 aerospace-grade body. The embedded rail-and-screw design reduces mounting footprint while delivering ISO-grade positioning stability for semiconductor, optical, and inspection applications.
