Do you know something about CNC grinding machine?The grinding methods can be divided into cylindrical grinding, internal grinding of CNC lathes, centerless grinding, surface grinding, forming grinding, gear grinding, thread grinding, tool grinding, and ordinary lathe surface grinding. Corresponding NC grinding methods have become more and more important in the grinding process with the development of NC technology. CNC grinders are capable of processing some special parts that cannot be machined on ordinary grinders (such as shaft parts with special curves, special-shaped parts with more than three coordinate requirements, molds, etc.), so it can be used to process a wide range of parts. In order to make the most of the economic benefits of CNC grinding machines, the following processing objects can be given priority consideration.
The preparation man-hours of processes using CNC grinders occupy a high proportion. For example, process analysis preparation, programming, part first part adjustment and 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 processing of a single part of a part. Process files, programs, etc.) can be saved and used repeatedly, so when a part is successfully trial-produced on a CNC grinder and then put into production again, the production cycle is greatly reduced, the cost is also small, and better economic benefits can be achieved.
CNC grinding machine can realize high-precision, high-quality, and efficient grinding processing under the control of computer. 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 processing, has good consistency and interchangeability of processed parts, and high processing efficiency.
When CNC lathes are processing non-NC grinding machines for small and medium batch parts, due to various reasons, the pure cutting time only accounts for 10% -30% of the actual man-hour. When processing on a CNC grinding machine such as a grinding machining center with multiple processes, this ratio may rise to 70% -80%, but the adjustment of man-hours tends to be much longer, so if the batch of parts is too small, it will become uneconomic.
When a CNC grinding machine processes apart, the condition of the workpiece being cut by the grinding wheel is exactly the same as that of the corresponding non-NC grinding machine, but it can perform some composite machining with processing accuracy requirements. For example, in the area of grinding, ordinary grinding machines are mainly used for grinding cylinders. Surface, circular CNC lathe tapered surface or stepped shoulder ordinary lathe grinding, in addition to CNC cylindrical grinding machine, in addition to grinding circular surfaces (including convex and concave surfaces), as well as the above various forms of complex Combination surface.
Although some parts have small processing batches and ordinary lathes, they have complex shapes and high quality and require good interchangeability. This cannot meet the above requirements on non-NC grinders. They can only be processed on CNC grinders, such as a parabola, cycloid cam As well as mirrors with special profiles.
