CL CNC Series Lathe

Please call for a quote


The ‘CL’ series range of lathes are our Premium range of lathes made from the highest quality castings which are stabilised and stress relieved. The bedways are hardened to minimum HS-70 and we include Turcite B coating between the bed and carriage. The machines are extremely quite with extremely low vibration even at high speed due to the wide bed ways. The machines are fitted with Heidehain DRO system as standard and are available with optional variable speed and optional constant surface speed.
