When accepting machine tools according to this standard, the remaining acceptance items in GB9061, ZBnJ50008.1, ZBnJ50008.3 and other standards that are not specified in this standard must be inspected at the same time. 4 Accessories and tools
4.1 A set of anchor screws should be supplied randomly.
4.2 Special accessories and tools (such as automatic tool holders) can be supplied according to the agreement. 5 Safety and Health
5.1 The machine tool should have a reliable overload protection device. 5.2 The noise of the machine tool shall be tested in accordance with the provisions of ZBJ50004. The noise measurement of the machine tool shall be carried out in the idle operation at three speeds of high, medium and low. During the measurement, all moving parts must move. The noise sound pressure level index shall not exceed 83dB (A). 5.3 When accepting the machine tool according to this standard, the remaining acceptance items in JB4139 that are not concretized in this standard, as well as the relevant safety items specified in standards such as GB/5226.1 and ZBJ50016, shall be inspected at the same time. Processing and assembly quality
6.1 The bed, tailstock, main slide plate and auxiliary slide plate are important parts and should be aged after rough processing. Approved by the Ministry of Machinery Industry on November 7, 1996
Implemented on January 1, 1997
