Vertical Machining Center VMC1260
The base parts are made of high-strength cast iron and aged to ensure the stability of accuracy; X, Y, Z three direction feed using large pitch, high precision and high strength ball screw, feed speed is high; The servo motor is directly connected with the lead screw using the elastic coupling to ensure the positioning accuracy of the machine. The lead screw is pre-drawn structure, which greatly reduces the influence of thermal deformation on the positioning accuracy;
While selecting a reasonable cutting amount, try to choose a dense tooth cutter (23 teeth per inch diameter of the tool) to increase the feed rate per tooth, improve productivity and tool life. Experimental studies have shown that when the linear speed is 165m/min and the feed rate per tooth is 0.04mm, the feed rate is 341m/min and the tool life is 30 pieces. If the cutting speed is increased to 350m/min and the feed rate per tooth is 0.18mm, the feed rate will reach 2785m/min, which is 817% of the original machining efficiency, and the tool life will be increased to 117 pieces. mouth
