The processing accuracy and processing speed of CNC grinding machines are the highest among all grinding machines, and are suitable for processing complex and special-shaped parts. This equipment can realize computer system control, eliminate human factor deviation, and improve the precision of machine equipment processing. Operators can also complete the compensation and optimization control of system accuracy through computer technology, so as to better control system production. The operator should switch the tool setting function according to his own judgment, reduce the clamping frequency and improve the machining accuracy.
Six basic machining knowledge of CNC grinding machine:
1. Parts with repeatable production are more economically beneficial
The preparation time for the process of using CNC grinding machines occupies a relatively high proportion. For example, the preparation of process planning in advance, program editing, and trial cutting of the first sample of parts. Special-purpose general lathe fixtures, process specifications, program flow, etc.) can be saved and reused. Therefore, when a part is successfully trial-produced on a CNC grinding machine and put into production repeatedly, the production time is greatly reduced and the cost is relatively small. Stronger economic benefits.
2. The key is to ensure the processing quality and high-efficiency manufacturing process, and to produce important parts in small batches
CNC grinding machines can complete high-precision, high-quality, and more efficient grinding processes under the control of computer systems. Compared with special-purpose grinding machine processing, it can save a lot of special-purpose mechanical assembly, has a strong flexible manufacturing system capability and better economic benefits. Compared with ordinary grinding machines, it can eliminate many human uncontrollable factors in the complicated and long production process, the precision of the processed parts is good, the exchangeability is good, and the processing efficiency is high.
3. The large batch of parts processed should be larger than the large batch of general grinding machines
When CNC grinding machines are used to process parts in small and medium batches, due to various reasons, the pure drilling time only accounts for 10%-30% of the specific construction time. When processing on a multi-process-intensive CNC grinding machine such as the grinding core, this ratio may rise to 70%-80%, but the preparation and adjustment construction time is usually much longer, so the large batch of parts takes too long It will also become uneconomical.
4. The processed parts must conform to the process principle that can make full use of the multi-process centralized processing of CNC grinding machines
When the CNC grinding machine is processing parts, the grinding wheel drilling workpiece is exactly the same as the corresponding non-NC grinding machine, but it can perform some compound processing with processing accuracy requirements. If it is in the grinding category, the general grinding machine is mainly used for grinding Grinding of circular, spherical or stepped shaft shoulder ports with general grinding machines. In addition to the inner hole grinding machine of CNC machine tools, it can also grind circular surfaces (including convex and concave surfaces), as well as various forms of complicated matching surface.
5. The balance of the comprehensive processing level of parts
As each CNC grinding machine, it is difficult to complete all the processing details of a part, and it needs to be connected and coordinated with the processing procedures of another machine, so there are requirements for production cycle and workshop production balance. Therefore, to understand and fully utilize the processing characteristics of CNC grinding machines, CNC grinding machines must scientifically allocate supporting facilities and balance processes among other processing equipment.
6. Processing considerations for some special parts
Although some parts are processed in small batches, ordinary lathes have complicated shapes, high quality, and good interchangeability. This cannot meet the above requirements on non-NC grinding machines. They can only be processed on CNC grinding machines, such as hyperbolas and rotary wheels. Linear camshaft and its unique profile mirror mirror glass and so on.
The types of CNC grinding machines can basically be divided into high-end, popular and economical and practical. High-end CNC lathes refer to CNC machines that process complex shapes, can realize process centralization, and have a high degree of automation. The universal CNC lathe has the function of man-machine exchange, and is a kind of grinding machine widely used in today’s society. The structure of economical and practical CNC lathe is relatively simple, the precision is medium level, and the price is low, which is suitable for the application of some small and medium-sized manufacturers. Although this product can only be processed with general precision standards, it has a group of customers from small and medium-sized manufacturers.
