CL Series - Flat Bed: Large Bore and Long Bed Capacity #
The CL Series flat-bed CNC lathes are KINWA’s answer to large workpieces, long shafts and jobs that require a big spindle bore. The range starts with the CL-650 and extends to the CL-38, CL-58, CL-68 and CL-78, with swing over bed from 660 mm to 1,500 mm and between-centers lengths up to 6,430 mm.
These machines are widely used for oil and gas components, large shafts, rollers, flanges, pipe fittings, energy parts and other heavy or long workpieces. Multiple spindle bore options allow the machine to be matched to bar size and chuck requirements.

The CL-58, for example, can be ordered with spindle bores of 120, 186, 258 or 375 mm and between-centers lengths from 1,115 mm to 6,430 mm. The CL-68 and CL-78 add a larger 1,150/1,500 mm swing and spindle bores up to 530 mm.
Design Focus #
- Large spindle bore options — Up to Ø530 mm on CL-68/CL-78 for large bar and pipe work.
- Long between-centers capacity — Supports long shafts, rollers and pipeline components.
- Heavy-duty bed — Bed width ranges from 400 mm on CL-650 to 1,000 mm on CL-78.
- High-torque spindle — Main motors from 15 HP to 60 HP depending on model.
- CNC control — Programmable turning, threading, boring and facing for repeatable production.
- Tailstock and steady-rest options — Available according to workpiece length and weight.
Typical Applications #
- Oil and gas pipeline components
- Large shafts, rollers and guide rods
- Flanges, rings and pipe fittings
- Energy and power transmission parts
- Heavy machinery components
