Six main characteristics of CNC lathe are high precision motorized spindle. The bearing of CNC lathe is matched with high speed bearing before and after. It has high speed, high rigidity, low noise, durable precision, and the spindle runs less than 3um. CNC lathe bed structure, CNC wire and rail lathe using high rigidity nano-cast iron, resin sand molding process, the foot of the bed and the overall structure of the bed with fluent chip removal, compact structure, beautiful shape and so on. The row cutter holder and the novel row cutter holder make the error of repetitive tool change to be minimum (+1um). The tool change speed is high and accurate, and the processing time can be greatly saved. High precision feeding, full servo drive of feeding axes, using Taiwan linear guide rail, ensures the accuracy of CNC lathe processing and long-term accuracy, and repetitive positioning accuracy of feeding axes < 1 um. The maximum speed of spindle of NC lathe with high efficiency is 5000 rpm, X-axis can move 16 m/min, Z-axis can move 20 m/min, high precision hydraulic rotary cylinder and precision elastic chuck. The high rigidity and precision power chuck configuration improves the cutting ability of tough materials and strong cutting. Powerful cooling high-power cooling pump, greatly improved the cutting of parts, according to customer requirements can be installed 1-4 cooling pipes, cooling performance is good.
