Clamping and clamping, modification and monitoring of the machine tool, ensuring basic safety, adjustment and maintenance of the machine tool, installation of the machine tool, including the installation of the sleeves and pads on the auxiliary parts, leveling and modification of the nuts, etc. 5.1 The exposed teeth, pulleys and other parts on the machine tool that may cause personal injury and extreme damage must be equipped with safety protection devices. 5.2 When the machine tool is working, the parts where the cutting wave is flying must be equipped with reliable anti-shovel devices. 5.3 The horizontal guide rail of the machine tool should be equipped with protective devices. 5.4 The indexing worm and the tool holder worm should be equipped with viewing windows and position indicators. 5.51. After the worktable is stopped in an emergency, it shall not automatically resume function after the radial dynamic rapid movement and the rotation of the axis. 5.6 The worktable is equipped with a maximum travel limit device for the quick movement seat. The machine tool shall not make any unusual screams or impact sounds when the machine tool is running at low, medium and high speeds.8u0--1250

Section 1 Machine Tool Idle Running Test
JB/T8361.2—96
7.【The machine tool idle running test is to run the main motion mechanism at a speed from low to high speed for many times. The running time of each speed level shall not be less than 1h, and the speed increase rate shall not be less than 2 times. The main shaft shall be transported to a stable temperature, and the bearing temperature shall be measured at the position near the main shaft bearing. The value shall not exceed the provisions of Table 7.
Bearing type
Sliding shaft
Rolling technology is the most important
. 2. The hydraulic system should be operated in reverse under the designed working pressure, and the humidity should reach the fixed value. The temperature rise should not exceed 20%. 3. Inspection of radial motion and radial feed motionWww.bzxZ.net
Inspect the actual deviation of the shaft rotation and radial feed. They should not exceed ± % and 10% of the indicated value on the label respectively. 7.4 Action test
Start and stop the shaft in forward and reverse directions continuously for 10 times at medium speed to test the slowness and possible action of the movement. 7.5 Idle running power test (spot check)
After the main pump of the lathe runs idle at the stage speed until the power is stable, check the idle power of the main transmission system (referring to the no-load power of the motor), which shall not exceed the design requirements.
7.6 Light machine reverse idle running test
Simulate the working state under the function of the machine. The idle running test shall be carried out successively. The running time shall be at least ten days. No technical failure shall occur during the operation of the whole machine.
8 Machine tool precision inspection
8.1 The machine tool shall be carried out in accordance with FB/T8361.1
8.2 The precision inspection of the machine tool shall be carried out once and passed. The maximum allowable tooth surface roughness R of the test piece after precision flow is 1.2iur)9 Machine tool working test
According to the agreement between the manufacturer and the user, the same cutting specifications and methods for processing different types of test pieces shall be adopted. Additional Notes:
