Auto industry manufacturers adopt the advanced method of new product development, virtual manufacturing, the development of advanced technology such as concurrent engineering, it is important that benefit from the equipment for automotive manufacturing equipment suppliers, especially is the equipment supplier provides all kinds of automatic lathe, the automatic lathe processing allows the automobile manufacturing industry manufacturers with the fastest speed to provide products to meet the market demand. 4.0 car manufacturing industry production, new product development cycles are shortened, the cost has been reduced, the data shows, a decade ago need four years of automotive products development cycle; Only need two years can be completed today.

Automatic lathe processing Classification and Features
    There are many automatic lathe processing; from the sub-categories, there are private automatic lathe, with universal automatic lathe processing; processing from the sub-species, there are automatic lathes CNC milling machining housing type, processing center, has a processing shaft automatic lathes, turning center, CNC cam grinder; from the control requirements for automatic lathe of points, there are single-axis CNC CNC belt sander, five linkage CNC gear cutting machines, CNC hob grinding; from sophisticated control of the points, there is a simple numerical control, multi-channel CNC; from the drive way points, a stepping motor with a DC servo motor, AC synchronous servomotors, AC asynchronous servo motors with linear motor; spindle drive on the way from points, DC spindle motors, AC spindle motor, there is an AC spindle; from the position feedback points, closed-loop feedback, there are semi-closed loop feedback, there are open-loop control, and so on.
    Automatic lathe good flexibility, high adjustment, high precision, has long been concerned about the automaker, the 1960s began to enter the production of automotive parts and components manufacturing. Because of its high cost, functionality and efficiency of the system is not ideal, but has not been widely used. In the 1990s, along with market competition; many varieties to maximize production to meet the diverse needs of the market, until automatic lathes to satisfy every user's needs, the automotive industry has become the goal maker to CNC machine tools as the main flexible manufacturing cell, has been widely used. Focus on the development of today's CNC machine tools are two: high-speed automatic lathe, to achieve high efficiency at high speeds. The current international level is the spindle speed ≤25000rpm, add, subtract speed ≤2.5g, fast-moving ≤160m / min, to achieve this new level of CNC machine tools drive, mechanical drive, the mechanical structure, the tool should have a lot of Improve. Machine tool spindle must spindle, main bearings generally use ceramic bearings, difficulty is cooling, lubrication, life in general 20,000h. General linear motor drive plus linear guides (also useful for hydrostatic guideway), 90m / min, 1g machine is also useful dual servomotor large ball screw pitch double pretensioner driven program. Mechanical structure commonly used to frame structure. Tools with high hardness and high heat tool, using HSK shank for shank.
    Automatic lathe processing plane of either dedicated CNC machine tools to solve the contradiction between flexibility and high efficiency. Currently, European and American automobile manufacturers are mostly used by the agile production system consisting of high-speed machining center, such a system can be 100% of the production of flexible mixed varieties, called island by a plurality of flexible processing units, each island by more than one grade The machine tools and robots connected components, the use of the machine with the tray reservoir with electronic exchange of information. It is noteworthy that these equipment suppliers not only mastered the equipment manufacturer's proprietary technology, and attach great importance to the development of automobile manufacturing process, they are able to provide turnkey project to users, have their own system development capabilities. Machine reliability is extremely advanced, single starting rate of 98%. With this production system, automotive industry manufacturers of new product launch cycle shortened industrialization.
    After twenty years of reform and opening up in the domestic automobile manufacturing parts manufacturing, use automatic lathe processing more widely.
