The newly improved Star SR-10J model has enhanced secondary machining capability and operability with C-axis control on both the main and sub spindles. This high performance machine was designed with advanced features for machining small parts with its high spindle speed (15,000 RPM) and rapid traverse with 3-spindle drilling unit for secondary machining. The dynamic and efficient design of this machine allows for close cutting position to the guide bush which achieves accuracy for small parts machining.
