Tips On CNC Lathe Machining

Tips On CNC Lathe Machining

Repetitive production parts machinined by CNC lathes: The process preparation time using CNC grinders accounts for a high proportion.

Tips On CNC Lathe MachiningFor example, process analysis preparation, programming, part first part adjustment trial cutting, etc., the total of these comprehensive man-hours is often several tens to hundreds of times the number of man-hours for the cnc machining of a single piece of a part, but these CNC lathes can be saved and used repeatedly, so When a part is trial-produced successfully on a CNC grinder and then repeatedly put into production, the production cycle is greatly reduced, the cost is also small, and better economic benefits can be obtained.
    It is required to focus on the key parts of medium and small batches that can guarantee the machining quality and can be efficiently produced: CNC grinding machines can realize high-precision, high-quality, and efficient grinding machining under the control of computers. Compared with the special grinding machine, it can save many special process equipment, has strong flexible manufacturing capacity and obtain better economic benefits. Compared with ordinary grinders, it can eliminate many artificial interference factors in the long process flow of complex machining, has good consistency and interchangeability of processed parts, and high machining efficiency.
    The parts processed by the CNC lathe should meet the technical characteristics of the multi-process centralized machining of the CNC grinder. When the CNC grinder processes the part, the condition of the workpiece cut by the grinding wheel is exactly the same as that of the corresponding non-NC grinder, but it can perform some machining accuracy requirements For complex machining, for example, in the area of grinding, ordinary grinders are mainly used for grinding cylindrical surfaces, circular CNC lathes, tapered surfaces, or end faces of stepped shoulders. Torus, and the complex combination of the above various forms.
    The machining batch size of the aluminium parts should be larger than that of ordinary CNC lathes and batches of CNC lathes in the machining of non-NC grinders for small and medium batches. Due to various reasons, the pure cutting time only accounts for 10% -30% of the actual working hours. When machining on a CNC grinder with a multi-process concentration such as a grinding machining center, this proportion may rise to 70% to 80%, but it is often much longer to adjust the adjustment time, so the number of parts will be too small to become uneconomic.
    Considering the machining of some special parts of CNC lathes, although some parts are processed in small batches, ordinary lathes have complex shapes and high quality, and require good interchangeability. This cannot be achieved on non-NC grinders and can only be arranged to Machining on CNC grinders, such as parabola, cycloid cam, and special mirror surface.
