KA series high-precise motorized linear stages
KA series products are designed as a group of middle-size and middle-travel-range high precise motorized stages.
The base plates in this series employ high-rigidity U-type structure to ensure this series could be suitable for the operations in the circumstances of heavy load, high rigidity and multi-dimension combinations.
A stainless-steel dustproof cover is optional to protect all inner parts of stages from particles and dust in real operation environments, which could guarantee better stability, durability and the capability to keep a long-term accuracy.
KA series products employ precise-grade ball screws, linear-slider guides and high-performance Shaft coupling units.
This kind of design offers good adaptabilities for being used in accurate operation scenarios with relative complex environments.
An external grating ruler is used with Zolix controllers MC600 or TMC-USB to ensure 1μm closed-cycle resolution.
The other key specifications of this series are also same or similar as those best ones worldwide.
Features

- - External imported grating ruler to ensure 1μm closed-cycle resolution
- - Precise-grade linear-slider guides are used to guarantee high load capability and high motion accuracy
- - Stainless steel dustproof covers are optional
- - Two-phase stepping motors standard, servo motors optional
