CNC CNC lathe processing repetitive production of parts: the use of CNC grinding machine process preparation time occupies a high proportion. For example Process analysis preparation, programming, adjustment and trial cutting of the first part of the part, the sum of these comprehensive working hours is often dozens to hundreds of times of the working hours of a single part of the part. However, the work contents of these CNC lathes can be saved and reused. Therefore, when a part is successfully trial produced on a CNC grinder and put into production again, the production cycle is greatly reduced, and the cost is also less, which can achieve better results The economic benefits of.
It is required to focus on ensuring the processing quality and producing the key parts in small and medium batches: CNC grinder can realize high precision, high quality and high efficiency grinding under the control of computer. Compared with the special grinding machine processing, it can save a lot of special process equipment, has strong flexible manufacturing ability and obtains better economic benefits. Compared with ordinary grinding machine, it can eliminate many artificial interference factors in the long process of complex machining, and has good precision consistency and interchangeability, and high processing efficiency.
The parts processed by CNC CNC lathe should conform to the process characteristics that can give full play to the multi process centralized processing of CNC grinder. When CNC grinding machine processes parts, the situation of grinding wheel cutting workpiece is exactly the same as that of corresponding non CNC grinder, but it can carry out some complex processing with processing accuracy requirements. For example, in the grinding range, ordinary grinder is mainly used for grinding cylindrical surface and circular CNC lathe In addition, it can also grind toroidal surface and complex combined surface of various forms mentioned above.
The processing batch size of parts should be larger than that of economic batch of parts by ordinary lathe. When NC lathe is used to process medium and small batch parts by non CNC grinder, due to various reasons, the pure cutting time only accounts for 10% – 30% of the actual working hours. When CNC machining is carried out on the CNC grinding machine with multi process concentration, such as grinding center, the proportion may rise to 70% – 80%, but the man hour to be adjusted is often much longer, so it will be uneconomical if the parts batch is too small.
Some special parts processed by CNC lathe are considered to be processed. Although some parts are processed in small batches, ordinary lathes have complex shapes, high quality and good interchangeability, which can not meet the above requirements on non CNC grinding machines. CNC machining can only be arranged on CNC grinding machines, such as parabola, cycloid cam and special surface mirror mirror.
