This standard is based on the technical requirements for the manufacture and acceptance of modular machine tools in ZB158008-88. This standard is a concretization and supplement to GBT9061-1988 "General Technical Conditions for Metal Cutting Machine Tools" and other standards. This standard is consistent with the technical content of ZBJ58008-88, and only the relevant provisions have been re-edited. This standard will replace ZBm58008-88 from the date of implementation. This standard is proposed by the Jin Guo Metal Cutting Machine Tool Standardization Technical Committee. This standard is under the jurisdiction of the modular machine tool branch of the National Metal Cutting Machine Standardization Technical Committee, and the responsible drafting unit of this standard is Dalian Modular Machine Tool Research Institute. This standard was first issued in 1988.

4,! In order to ensure the basic performance of the machine slide, the variable gear should be provided according to the user's requirements: 4.3 The manufacturer should provide the required seals, and the number of accessories is twice the number of the slide used. 4.3 The finished parts must be equipped with the tightening screws and positioning pins for the specified installation. Comments: The corresponding marks or specifications of the random coordinates are not included. 5 Manufacturing qualitywwW.bzxz.Net
5.1 General requirements
Approved by the State Machinery Industry Bureau on May 20, 1999 and implemented on January 1, 2000
JB9888-1999
5.! .! The connection size of the machine table should meet the requirements of the relevant documents: 5.1.2 The technical conditions of the iron parts should meet the requirements of JDT3997 5.1 The performance of the coated material or plastic parts of the slide rail should meet the requirements of JB357B, and the performance and requirements of the coated guide rail must meet the requirements of JDB/T3579
5.3 The straightness of the plane on the slide rail in the vertical plane is not concave, 5.4 When using trapezoidal screw and nut, the small precision single should meet the requirements of the torque standard: When using rolling screw and cold cutting, the beat should meet the requirements of GDT17587.3.
5.5 The coated guide and the matching guide rail are connected evenly, and the inspection method is the same as that of JBT9876. The indicators are not less than those in the table. The table
bone platform system identification
full-level mechanics
sugar sieve short [7 test kidney white

only when the length of the key is fully connected to the required length, this night is used as the length calculation position. The guide surface of the matching guide machine is inspected according to the inspection indicators 2
3 and the layer guide rail is called a matching guide rail, and the surface of the guide can be used for the navigation of the coating. In addition to the comprehensive inspection and monitoring, a 0.4mm cold ruler is also used for inspection; the depth of the wide ruler inserted between the guide rail, the fuel bar, and the moving surface of the five-plate end shall not exceed 20mm:
6 Idle operation test
1 Place the submersible on the corresponding test bench and conduct an idle operation test for at least 2 hours. During this period, the specified working cycle must be achieved, the action must be smooth and reliable, the various action conversions must be correct and smooth, there must be no obvious impact, and the slide in-situ switch must not fail. 6.2 The maximum stroke length of the slide, the fast moving speed, the fast return speed and the working feed speed range shall all comply with the requirements of the slide design. Within the working feed speed range, the slide moves smoothly without any abnormal phenomenon: 6.3 The electromagnetic coupling of the actuator shall not make any sound or obvious swimming phenomenon. 7.1 Carry out a load test according to the specified feed force to test the stability of the feed force. As shown in Figure 1, use a load cylinder and a force measuring device to test the load of the slide at the height of the work surface (or the width of the slide saddle) at the center of the front end of the slide. .2 Adjust the slide to the maximum force and feed the slide at the minimum feed speed. After the batch is started, the slide is operated again, and the feed force is adjusted. The change range of the feed force shall not exceed 15% of the specified maximum feed force. The test must be accurate. 7.3 The maximum feed force specified by the slide plus 15% can be used as the maximum load. Perform a load test at an appropriate feed speed. This should be normal for all slides.
Comment: High-end microcomputers are not tested in this way. 7, 4 in the city with a small feed rate, the speed change of the machine when it is no-load under the maximum feed rate is tested, and its efficiency is [rotten! "1] No flow exceeds 5%, and the test is continued for no less than 10 times in 10 correct loops. a = Sn-x1n19%
Where: 5
Feed speed change rate:
Normal feed speed without load, mmm; limit feed speed under specified load, mmmin. S
7.5 When the slide is fed directly at the minimum feed under the above specified load, there is no creeping phenomenon. Use a dial indicator to touch the front end of the slide saddle. Check the movement of the slide. The needle should be 7 stable and the jump should not exceed 0.01mm. It can be measured with a detection effect not less than that of a dial indicator and other instruments. 8 Accuracy inspection
The accuracy of the machine plate slide should be inspected according to B9889, and the inspection results should be recorded in the product certificate.
