Acceptance is generally carried out in two stages.
1. pre-validate
The purpose is to check and verify whether the machine tool can meet the user's processing quality and productivity, and to check the information and spare parts provided by the supplier. The supplier can only carry out pre-acceptance after the machine tool has passed the normal operation trial cutting and has been inspected to produce qualified workpieces.
2. Final acceptance
According to the acceptance criteria, the technical indicators provided on the certificate are determined, and the acceptance work is divided into the following steps:
(1) Unpacking inspection;
(2) Visual inspection;
(3) Acceptance of machine tool performance and CNC function;
(4) Acceptance of CNC machine tool accuracy (including position accuracy and working accuracy).
When accepting the geometric accuracy of the machine tool, it should be completed at one time after the fine adjustment of the machine tool, and one item of inspection is not allowed to be adjusted. The position accuracy inspection shall be carried out according to the corresponding accuracy acceptance criteria. The working accuracy of a machine tool is a comprehensive accuracy, which not only reflects the geometric accuracy and position accuracy of the machine tool, but also includes errors caused by various factors such as the material of the test piece, ambient temperature, tool performance and cutting conditions.
In the acceptance of CNC machine tools, strengthening the inspection of the above aspects is very beneficial to equipment management and can reduce unnecessary losses.
