PRECI-TURN EN-SERIES Heavy Duty CNC Turning Centres
   
 
   
  Overview
  Preci-Turn NX-Series Heavy Duty Straight Bed CNC Machines are specially designed for long heavy duty shaft type jobs. Heavy duty construction of the machine is the key feature of the machine to turn a job very precisely with shortest machining time for a long period.

Spindle is mounted on Super Precision Angular Contact Bearings at both the ends. Spindle & Headstock assembly is so designed to deliver higher accuracy as well as axial & radial stiffness.

Machine Control Panel (MCP) having all the controls of the machine and fixed to achieve maximum operating convenience.

Tool Turret is available with Live Tool option to facilitate Turning, Milling & Drilling on the same single set up (Optional for higher versions of CNC controllers).
