This standard is a supplement to the specific specifications of G906126.J50008.1, ZErJ>VU08. When accepting the acceptance method of this standard, it is necessary to conduct control inspection on the remaining rectification items specified in this standard. 4 Accessories and tools
4.1 The machine bed and electric feet should be supplied with a set of screws and pads for installation (the electric feet need to be nailed and screwed). 4.2 Special accessories can be supplied according to the agreement.
5 Full sanitation
5.1 The workbench! The lower die > forward or reverse movement, limit position or prevent the replacement of the insurance device 5.2 The machine must be equipped with a positive plate to prevent the coolant from flying Yao, the bed guide wheel and other parts that are easily damaged by dust or material, and there is no active stomach.
5.3 The following parts of the machine tool should have a safety interlock device: The door (or cover) of the machine tool electrical box is not closed. The machine will start the machine. Apply oil to the inner surface of the door (or cover) and check the outer surface of the door (ton benefit) in Figure 2-- of B2894. A warning sign; b. The dynamic smoothness of the moving parts The sequence of the system, the sequence of the system after the opening and closing, all have safety interlock devices; when the system power is not in the palace or a fault occurs, a warning signal or an emergency stop button should be issued, the port system of the old environment energy device, a force should be released or cut off the storage device for rest! : Power adjustment: d.www.bzxz.net

The workpiece is not moving in the three working cycles of the machine. E
5.4 According to the provisions of ZBJ50F4, the machine tool noise is inspected. The sound test of the machine should be carried out under the condition of the working cycle. The sound pressure level of the whole machine shall not exceed 8 (A),
5. The operating force of this series of machine tools is subject to the "not often used" requirement assessment 5.6 When accepting the machine tool according to this standard, it is necessary to simultaneously inspect the JI41 89 The remaining acceptance items that have not been fully integrated in this standard shall be inspected according to the acceptance items specified in standards such as GE5226 and 2ZBJ51016. 6 Machining and assembly
6.1 The machine tool bed, worktable, worktable bearing, oiled cylinder body, pressurized cylinder body and lower flange as the main castings shall be aged after roughing. The welded machine tool bed must be aged after welding. .2 The guide rails or slide bars between the machine tool bed and the worktable and the sliding pairs composed of them shall be wear-resistant. The eccentric wheel, oiled support and upper and lower plane cams shall be pre-grinded. 6.3 The following joints shall be assessed according to the requirements of the fixed joint surface: 8: The joint surface between the working part and the working self-supporting standard, b, the joint surface between the front column and the bed
The joint surface between the front column and the shaft body. e
6.4 The guide surfaces of the guide pairs of machine tools are assessed according to the requirements of the "Transfer Guide Model": 6.5 The clearance of the handle of the gear wheel with scale is not more than 1/2r6. Check the cleanliness of the machine tool according to the provisions of ZB.50003. Generally, it is checked by hand feeling method. The state of the oil in the oil tank (or oil tank) should not exceed 15C by using the quantitative method. m name/L. Machine tool idle running test
7.I Single action test
Single effect test should test the following moving parts. Each action should meet the delay requirements, H,
Workbench forward:
Die down,
Workbench backward:
Die up:
Machine tool workbench has some forward (backward) action, and it is also necessary to test the workbench point forward (backward) action. 2 Working cycle test
The working cycle test is carried out according to the requirements of Table 1 (cooling oil may not be injected). At the beginning of the test, all mechanisms of the machine tool should be completed. Table 1
When injecting oil
The amount of injection
The number of cycles (times)
8 Machine tool load test
8.1 This series of machines should be subjected to load test. The recommended commissioning number is shown in Table 8.2 The load test should be carried out continuously for 1 time
