The bed is designed with double“V” slideways for increased turning accuracy and straightness. In addition to the highly rigid bed structure, the foundation bolts are also strengthened making the bed more stable during turning operations.
With the special enhancement on the tailstock brake, the entire stability is increased when performing machining on an extra large shaft. MT5 or MT6 is optioned for tailstock quill taper application.
All models of the CHK series can be equipped with an optional high torque motor in combination with the highly rigid bed, fully exhibiting extra powerful heavy cutting capacity.
All models of the CHK series are in compliance with TS Mark in Taiwan,providing the operator with increased safety protection in machine operation.
The headstock employs a cam type speed change mechanism for reducing running noise. To use Japanese / European / American brand high quality bearings in the headstock provides a reduction of vibration during running.
