Description

KA series high-precise motorized linear stages Description: 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 1 m closed-cycle resolution. The other key specifications of this series are also same or similar as those best ones worldwide. Main characteristics: Fine machining for U-type aluminum alloy base plates, which are treated as black anodic-oxidation. High rigidity and nice appearance. External imported grating ruler to ensure 1 m 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 Naming rules:
