China Heavy Duty Large Diameter Horizontal Lathe Machine

Heavy Duty Large Diameter Horizontal Lathe Machine
Features:
1. These lathes are suitable for turning cast iron and steel workpiece, turning of nonferrous metal parts of big or medium sizes.
2. It can do external cylindrical surface turning, inner hole and end face turning.
3. It can also turn various internal and external metric, inch, module and diametrical pitch threads, the top slide can be used independently for turning of short taper.
4. These lathes are of high power, high rigidity and wide rotating speed range, so it can be used for high speed and strong force turning.
5. Bed with high rigidity
Casted in whole piece, box type internal structure, of high rigidity, with hardened guideway, TSF coated carriage to minimize the possibility of low speed stick-slip.
6. Main spindle with high rigidity and high accuracy
Spindle comes with bearing of famous brand, spindle-box of heat-symmetrical structure to avoid spindle axis drifting, oil lubricating to minimize heat distortion.
Spindle comes with three support structure to secure accuracy and increase rigidity, all gears quenched and tooth-ground to secure precise transmission and low noise, so the spindle is of low temperature rise, minimized heat distortion, and long-term steady high accuracy.
Optional accessaries:
Big center rest; Big centering bracket; Motor Driven Tailstock and Tailstock with totarg guill; Chuck guard, tool post shield, cable carring chain.
