This standard is for the requirements and inspection methods of the working accuracy of each lathe before setting the adjustment of the rolling mill. This standard is applicable to the measurement of 439~200cm of the two pieces of bad fire, and the total length of the pieces is 10,000 a. 2. Reference standards: The standard clauses in a list of standards are referenced in this standard and become the clauses of this standard. When the standard is published, the following clauses are still subject to change: The parties to the standard should explore the possibility of using the following standards: E/T1182-1596 Position tolerance and position tolerance rules. Complete symbol diagram method B267062 General requirements for precision inspection of cutting machine tools 3. According to B26702.1 Adjust the water level. Place the plate on the guide rail of the bed, and adjust the guide rail slightly at both ends of the machine tool. The horizontal direction is 0.06/1C. 3.2 The top adjustment test can be carried out in the table. The load test and re-inspection are not required. 3.3 During the inspection, the tools and inspection force can be connected. The inspection items are required to be inspected on the same day. Arrange the original inspection order. 3.+1. During this inspection, the inspection should be carried out according to the car. 3.5 When the actual length is different from the length specified in this standard, the length specified in JB2570822.3.1.1 should be calculated according to the length specified in JB2570822.3.1.1.
3.6 The parallel bed is called the level room, and the vertical bed is called the picking room. National Machinery Industry High 1998--17 approved
