What problems are prone to occur during CNC processing?

As we all know, the processing technology carried out by CNC processing is now high efficiency and good quality, especially the best accuracy. But we often say that there are pros and cons. If we operate improperly during the CNC processing process, it is easy to cause some unavoidable problems.

According to the experience of Dongguan CNC processing manufacturers , the following problems are common in CNC processing operations:

The first problem: The CNC processing process is too dispersed

The CNC machining process is too dispersed, and the reason is that the processing preparation time is insufficient, the programming is simple, the operation is simple, the use of one knife is easy to adjust, the adjustment of the knife is easy to adjust, and the habit of ordinary processing. This makes it difficult to ensure product quality (position tolerance) and production efficiency cannot be fully utilized.

Therefore, CNC processing technicians and operators should fully understand CNC processing knowledge, make more attempts, master relevant knowledge, and try to use concentrated process methods for processing. Use it a few times more, which will naturally reflect its superiority. The use process is concentrated and the unit processing time is increased. We arranged two equipment face-to-face to realize the operation of one person and two machines, greatly improving production efficiency and well guaranteeing quality.

The second question: The CNC processing order is unreasonable

Some CNC machining operators often arrange the processing order in an extremely unreasonable way considering some issues in processing preparation. CNC machining is generally processed according to the requirements of conventional processing technology, such as coarse first and then thin (changing tool), inside first and then outside, and reasonably selecting cutting parameters, etc., thereby improving processing quality and efficiency.

Careful use of G00 (G26, G27, G29) fast positioning instruction G00 brings great convenience to programming and use. However, if set up and used improperly, it will often cause adverse consequences such as overshoot when returning to zero due to excessive speed setting, reduced accuracy, and strain on the equipment rail surface. If the zero return line is not careful, it is easy to cause safety accidents in collision between workpieces and equipment. Therefore, when using the G00 command, you must consider it carefully and not be arbitrary.

The third question: Strengthening program search and testing issues

In CNC processing, special attention should be paid to strengthening the search and debugging of procedures. When the program enters the control system, the operator should use the SCH key and the ↑, ↓, ←, and → move keys for uncertain search, and modify the program as needed to ensure the accuracy of the program. At the same time, before formally performing program processing, a program trial run (opening) must be carried out to determine whether the processing process complies with the design process.

The above three points are problems that are prone to occur in CNC processing operations. In fact, we will also encounter other small and small problems in actual work. However, as long as we carefully master the relevant knowledge and technology of CNC processing, we will definitely benefit the company. maximize.
