Horizontal Lathe （Flat Bed CNC Type）
Product Presentation:
The CKA series CNC lathes are horizontal CNC lathes with a flat bed controlled by both longitudinal (Z) and transverse (X) axes.
They can automatically complete cutting operations on various shaft and disc parts, including internal and external cylindrical surfaces, conical surfaces, arc surfaces, end faces, grooving, and chamfering.
They can also perform turning operations on metric straight threads, end face threads, and imperial straight and tapered threads. Suitable for the production of diverse, small-batch products, they demonstrate 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.
