SK50E easy-operated  CNC lathe


SK50E CNC lathe

Introduction

SK50E is an easy-operated CNC lathe driven by a 7.5KWmain motor. Outputs 4-step speed hydraulically with infinite variable speed within each step.Either 4-station turret (standard equipment) or 6-stationturret can be equipped for cutting different shapes of work pieces. The lathe has beautiful guard. Its well designed sliding door is easy to use and functions as a protector of operators’ safety.

Features: steady start, quick stop, high output torque.The lathe is suitable for turning shaft type and plate/ring type work pieces.Operations performed on the lathe are ID/OD turning, any taper turning, arc surface turning, facing and metric/inch threading. It is suitable for cutting multi specification work in batches, especially complex and high precision work pieces.

8″/10″ hydraulic power chuck and hydraulic tail stock are available on request.
