The 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 carry out pre-acceptance only after the machine tool passes the normal running test cutting and the production of qualified machining parts is inspected.
2. Final acceptance
According to the acceptance criteria, determine the technical indicators provided on the certificate, the acceptance work is divided into the following steps:
(1) Unpacking inspection;
(2) Visual inspection;
(3) Acceptance of machine tool performance and numerical control functions;
(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 once after the machine fine-tuning, and it is not allowed to adjust one inspection item. The position accuracy inspection shall be carried out in accordance with the corresponding accuracy acceptance standards. 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, the ambient temperature, the tool performance, and the 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.
