• Thread-cutting gearbox: Gears are compact and coordinated. It connects the gearbox with two sets of change gears.
• Gearbox: Gearbox and headstock adopt fission structure. Convenient inspection and maintenance . Gears processed by grinding have excellent precision. Equipped with the oil filters and gear lubrication pump.
• Headstock: Spindle speed up to 2000 rpm. It connects the guideway in “Vee”shaped way, which ensures the stability and stiffness. In addition, radial vibration decreased.
• Bed: Reasonable structure with accurate finite element analysis and internal tendons form with rational layout ensures its high overall rigidity. Easy removal of chips.
• Carriage and Saddle: Scraped surfaces of saddle and guideway. Over stroke limitation resulting good safety protection.
• Apron: Handwheel located on the right hand side of the operator, directional lever situated on the left hand side. Easy operation and high safety.
• Tailstock: Scale shown on the sleeve and handwheel of the tailstock, which is easy to adjust. Its shape is in perfect harmony with the machine as a whole.
• The cooling equipment consists of centrifugal pump, a coolant tank, and a outlet pipe. The used coolant flows through a filter back into the tank situated on the floor
• High-power 7.5kw, 1400rpm.; Small vibration and low noise; durable design
