CNC machining center is a high-precision machine tool that is widely used in various fields in the manufacturing industry. Its main function is to convert parts from raw materials into finished products in a high-precision and efficient manner. However, even the highest-level CNC machining centers will have problems with substandard machining accuracy. This article will discuss the reasons why the machining accuracy of CNC machining centers is unqualified.

1. Machine tool quality issues

CNC machining centers need to have quality requirements such as high efficiency, high precision, and high stability. If there is a problem with the quality of the machine tool, it will affect the processing accuracy and lead to unqualified processing accuracy. Possible reasons for this problem include design and manufacturing defects of the machine tool itself, malfunctions and damage during the use of the machine tool, etc.

2. Tool problem

The cutting tools used in CNC machining centers are one of the key factors in its machining accuracy. If the tool quality is poor or used improperly, the machining accuracy will decrease.

3. Cutting fluid problem

CNC machining centers need to use cutting fluid during the machining process. The performance of cutting fluid directly affects the processing quality. If the cutting fluid is unclean, unclean or inappropriate, it will have an impact on the quality of the parts.

4. Process issues

CNC machining center processing parts requires reasonable processing technology, and any process problems will affect the processing accuracy and quality of the parts. For example, processing time, processing temperature, processing speed, processing sequence, etc. all need to be strictly controlled in accordance with processing requirements.

5. Operator issues

The level of the operator will also directly affect the machining accuracy of the CNC machining center. If the operation is improper, such as setting unreasonable process parameters, reckless operation, etc., the accuracy will be reduced. Therefore, operators need professional training and practice to ensure the normal operation of machine tools.

The reasons for unqualified machining accuracy of CNC machining centers may include machine tool quality problems, tool problems, cutting fluid problems, process problems and operator problems, etc. During routine maintenance, it is necessary to pay attention to these factors that may lead to a decrease in the quality of parts processing to avoid substandard processing accuracy.
