Main features
High-Rigidity Mechanical Structure
Structure integrated with bed & leg enables hard roughing operation. A wide, precisely polished guide way and unique bed design translate to excellent vibration absorption and ensure surface smoothness and high precision during hard roughing.
High-Performance Tailstock
It delivers precision machining through stable support of long-shaft workpiece.
