The operating force of the front bumper of the machine (or the vertical machine) shall meet the design requirements of the platform. 5.6 When accepting the machine tool according to the vehicle standard, the new front plate must be compared with the one in B4139 that has not been tested by this standard. The integrated acceptance items, as well as the acceptance items specified in G52 and 2R50016 standards, have been inspected. 6 Processing and assembly quality 6.1 The main parts such as the worm gear, worktable worm gear, fixed guide (or screw guide) edge block, bed, machine bed, center bed, secondary worktable, spindle, guide parts, etc. must be aged after the application. 6.2 The main thrust, tool shaft sleeve (or rack body), tool holder indexing rod, worktable lever, force cam and radial cam should adopt wear-resistant indexes suitable for the life. 6.3 The fixed guide rail (or guide rail) and the section guide in the small frame are important and basic damage guide pairs, and appropriate measures should be taken. 6.4 The following station joint surfaces should be reported as "important fixed station surfaces"; 8. The joint of the drive box and the bed (or industry column); 2. The joint surface of the gearbox and the bed vertical hanging); 3. The joint surface of the start box and the upper bed (or bed); 4. The joint surface of the tool holder worm body and the opposite frame (or bed); 5. The joint surface of the worktable worm body and the worktable body. 6.5 The following combinations shall be tested according to the requirements of "fixed combination surface": the combination between the column and the bed; b. The combination between the upper bed and the lower bed; The combination between the bed and the bed (or the worktable and the bed) of the machine tool with horizontal tooling, in: For machine tools with heavy structures, only the seat can be excavated in the return shop, (6 The matching surface of the slider in the tool channel and the fixed guide (or the rotating guide) shall be tested according to the requirements of "moving guide": The following guide rails shall be tested according to the requirements of "movable guide shaft*", and the guide surface of the bed and the work base (or vertical): b. The guide surface of the upper bed and the tool holder slide; Machine tools with inclined tool selection , the guide of the vertical sample and the bed (or the workbench and the body). 6.8 The handwheel (head?, handle and idle travel) with a measuring device should not exceed 1 red.

Table 2 |The idle running test of the machine 5[--320 Dyeing large diameter ->320 - 30c >50--125 7.! Test the heat transfer of the motor in Table 3. All motors are working normally. 1250 7.2 Test the bearing strength and temperature rise of the shaft in the high-speed and low-speed operation of the tool. It should meet the requirements of B1. 7.3 Test the reverse idle operation under the conditions of any, medium and high speed of the tool reciprocating motion , when the power is stable, check the idling power of the main motion system, which should comply with the design requirements (drawing). Table 3 Stroke range 7.4 Machine tool action test Average cutting speed At high speed During the test, the feed plate is at F5 and the feed wheel is at a fixed stroke. Operation time (not less than) is: Reverse stroke at an appropriate speed. Start the reciprocating motion of the spindle, test the gear cutter for 1 time, and check the reliability of the action. JB/T 8358-96 b, choose an appropriate circular feed continuous speed, test the start and stop of the tool tooth mesh feed movement 5 times, check the reliability of the circular feed movement, and the reliability of the tooth feeding movement; C. Check the reversible feeding mechanism. Check the column (or worktable) single-direction rapid movement, automatic horizontal feeding and the rapid reverse rotation movement of the worktable: start and stop 5 times in a row to check the reliability and flexibility of the action: 1. For machine tools with upper stop mechanisms, reverse the upper button 5 times and then automatically cycle 5 times to check the reliability of the upper stop mechanism.

No fault should occur. The rest time between each cycle shall not exceed n. 8 Load test of machine tools 8.1 This series of machine tools should be tested by cutting method, so that the machine tool can reach the maximum power (or the maximum power according to the design). When the machine tool of finalized production is accepted, the load-low cutting test shall be carried out according to the design conditions and specifications. 9 Accuracy inspection of machine tools 9.1 The working accuracy and transmission accuracy shall be inspected according to the provisions of GB9059. 9.2 When inspecting the working accuracy, the maximum value shall be 2.5. Also, 93 users can perform the single and double-action movement of the workbench or stand on the body (or the force frame without the bed body) to make the single and double-action movement of the workbench, and the error should not exceed 6, U12mm. During the inspection, the measurement number should not be less than 7 times. The error is calculated by the maximum difference of the indicator number.
