CNC machine tool point inspection, is to carry out the state monitoring and fault diagnosis of the base, mainly including the following content:

(1) fixed point. First of all, to determine how many maintenance points a CNC machine tool, scientific analysis of this equipment, identify the possible failure of the location. As long as these maintenance points "watch", there is a fault will be found in time.

(2) the calibration. The maintenance points of the boat one by one to formulate standards, such as clearance, temperature, pressure, flow, tightness, etc., there should be clear quantity standards, as long as it does not exceed the specified standard is not fault.

(3) on a regular basis. How often to check, to determine the inspection cycle. Some points may be zhouban to check the children, some points may be a month or check once, according to the specific situation.

(4) items. There should also be clear rules on what items to check at each maintenance point. Boat point may check one item, may also check child item.

(5) a person. Who carries out the inspection, is the operator, maintenance personnel or technical personnel, should be based on the nc machine tool inspection parts and technical accuracy requirements, to implement the people.

6. Be a law. How to check also should have provisions, is artificial observation or instrument measurement, is to use ordinary instruments or precision instruments.

All landowners. The environment and procedure of inspection should be stipulated, such as inspection in production operation or shutdown inspection, disassembly inspection or non-disassembly inspection.

Was recorded. The inspection should be recorded in detail and clearly filled in according to the specified format. To fill in the inspection data and the difference between the specified standard, judgment impression, treatment opinion, the inspector should sign and indicate the inspection time.

Pet-name ruby processing. Check intermediate processing and v adjustment to timely processing and adjustment, and processing results recorded in the processing record. If there is no ability or condition to handle it, it shall promptly report to the relevant personnel and arrange for handling. But anyone, at any time to deal with must fill in processing record.

Attending analysis. Nc machining inspection records and processing records should be systematically analyzed regularly to find out the weak "maintenance points". That is, the point of high failure rate or the link of large loss, put forward suggestions, to improve the design of the designer. Nc machine tool point inspection can be divided into daily point inspection and full-time point inspection two levels. The daily spot inspection is responsible for the spot inspection, treatment and inspection of the general parts of the machine tool. Full-time spot inspection is responsible for key spot inspection and equipment status monitoring and fault diagnosis of key parts and important components of machine tools periodically, making spot inspection plans, making diagnosis records, analyzing maintenance results and putting forward suggestions for improving equipment maintenance and management, which is carried out by full-time maintenance personnel. As a working system, the point inspection of CNC machine tools must be carried out seriously and persevered to ensure the normal operation of machine tools.
