CNC lathe processing with good flexibility

- Jun 10, 2018 -

High adjustment, high precision machining, car manufacturers have long been concerned about, 60 years began to enter the field of automobile manufacturing parts and components production. Because of its high cost, system function and efficiency is not ideal, and has not been widely used. Into the nineties of the twentieth century, with the intensification of market competition; multi-species production to meet the needs of the market diversified to meet the needs of every CNC lathe processing users, as the automobile manufacturers to pursue the goal, to CNC machine tools as the main body of the flexible manufacturing unit, is widely used. Today, the focus of the development of CNC machine tools have two directions:
High-speed CNC lathe processing to high speed to achieve high efficiency. The current international level is the spindle speed ≤ 25000rpm, plus, deceleration ≤ 2.5g, fast moving ≤ 160m / min, to achieve this new level, CNC machine tool drive, mechanical transmission, mechanical structure, the tool should have a great Improve. The spindle of the machine tool must use the electric spindle, the main bearing is generally ceramic bearings, the difficulty is cooling, lubrication, the service life is generally 20,000h. Driving generally use linear motor plus linear guide (also used static pressure rail), 90m / min, 1g machine is also useful with large pitch double ball screw pre-tensioning program of dual servo motor drive. Mechanical structure is generally framed box structure. Tool with high hardness and high heat resistance tool, handle with HSK handle.
