CNC lathe CKA series

horizontal2-axisflatbed

Product Presentation:
The CKA series CNC lathes are horizontal CNC lathes with a flat bed controlled by both longitudinal (Z) and transverse (X) axes.

Capabilities:

• Automatic cutting operations on various shaft and disc parts including internal and external cylindrical surfaces, conical surfaces, arc surfaces, end faces, grooving, and chamfering.
• Turning operations on metric straight threads, end face threads, and imperial straight and tapered threads.
• Suitable for diverse, small-batch production; superior performance on complex, high-precision parts.

Machining Range:
Bed rotation diameter from 400mm to 800mm; workpiece length from 750mm to 5000mm, with custom length options available.
