Several reasons for the lack of process caused by CNC machining

Why do not pay attention to CNC Machining will lead to the lack of technology? Because the operator in the processing process of frequent product operation and program instructions. Next, CNC processing plant for you to answer the problem.

1, the cnc processing process is too scattered

The reason for this problem lies in the fear of complexity (referring to the preparation time), simple programming, simplified operation and processing, easy adjustment of tool setting with a knife, and accustomed to ordinary processing. In this way, the product quality (position tolerance) is not easy to guarantee, and the production efficiency can not be played well. Therefore, CNC machining process personnel and operators should be fully familiar with the knowledge of CNC machining, try more to master the relevant knowledge, as far as possible to use the method of process concentration for processing, more than a few times, will naturally reflect its advantages. After the process is centralized, the unit processing time increases. We arrange the two equipment face to face, and realize the operation of two equipment by one person. The efficiency is greatly improved and the quality is also well guaranteed.

2, the cnc processing sequence is unreasonable

Some CNC machining operators take into account some of the problems in preparation, often the processing sequence is very unreasonable. Shenzhen CNC processing plants are usually processed according to the requirements of the general machining process, such as first coarse and then fine (tool change), first inside and outside, reasonable selection of cutting parameters, etc., so that quality and efficiency can be improved.

With caution G00(G26, G27, G29) fast positioning instructions G00 instructions to the programming and use of a great convenience. However, if it is set and used improperly, it will often cause adverse consequences such as zero overshoot due to excessive speed setting, reduced accuracy, and strain on the equipment guide surface. Return to zero route not pay attention to, easy to produce collision workpiece and equipment safety accident. Therefore, when considering the use of the G00 instruction, it should be considered carefully and not arbitrarily.

In particular, attention should be paid to strengthening the retrieval and trial operation of the program in the CNC processing plant. After the program is input into the control system, the operator should use the SCH key and the ↑, ↓, ←, → movement keys to carry out uncertain and definite retrieval, and modify the program if necessary to ensure the accuracy of the program. At the same time, before the formal implementation of the program processing, it must go through the program trial operation (open the power amplifier) to confirm whether the processing route is consistent with the design route.
