4.1.4 The surface of the plastic top plate and the bottom plate of the drill bit should be smooth and uniform, and there should be no defects such as lines, bubbles, marks, spots, etc.
4.2 The thickness of the electroplated parts of the drill bit should not be less than 10u, and the plating surface must be uniform, without defects such as pores, missing casting, and flaking.
4.3 Joint and cutting materials
4.3.1 The moisture content of the wooden top plate and the handle should not be less than 16%, and there should be no defects such as ", cracks, scars and holes.

The quality of the drill plate and the sub-picking should be flexible and there should be no resistance. 1.5. 1
4.5.2 The ratchet of the auger must be able to withstand torque without any head loosening, damage or other issues. The center of the chuck of the auger must be within the same range as the chuck of the auger. The difference between the chuck and the auger must be compensated according to Table 1. 4.53
4.5.4 The auger must meet the requirements of the design. 5. Test method
. The dimensions of the auger and the heat exchanger must be tested with the most appropriate test. 5.2 Surface quality inspection
The surface quality of the auger must be inspected daily. 5.3 Electroplating quality
The thickness of the electroplated layer of the drill bit shall be determined by the method specified in G4955. If there is any dispute, the method specified in GB6462 shall be used.
5.1 Quality control of items and structures
5.4. The moisture content of the wooden plate and bottom of the drill bit shall be tested by the material moisture content test. 5.4.2 The missing plastic plate and handle shall be tested at a later date. 4.2.1 Immerse the plastic plate and handle in boiling water at 0.00 °C for 2 minutes and take them out to check whether they have any visible deformation: QB/r2510-2001
5.4. 2. 2 According to Figure 5 The test is carried out in the method shown in the figure. The test is carried out when the rope is completely straightened, and the rope is pulled open to the predetermined position along the plane perpendicular to the wall of the hit steel plate, and then the sample is released so that it can be pulled out of the hit steel plate with a thickness of 6mm.
This test is carried out 4 times in total, including 2 times in the shift and 1 time each for the two next vehicles. After the test, the material should not be damaged or lifted.

5.5 Chain strength test
The strength test of the user's drilling zero is carried out in accordance with the provisions of GB/T230. 5.6 Performance test
5.61 Safety standard for strength test 6.6.2 The torque test of the drill bit is carried out by the method shown in Figure 6. The test object is a support made of a straight fixed plate on a flat plate. The support is provided with a round hole suitable for the core. The mandrel to be tested should be rotated during the test. The diameter of the mandrel entering the round hole should be consistent with the diameter of the drill bit. During the test, the mandrel should be installed in the same way as the support to keep the original position. Then the rotation device is used and the upper, lower, middle and outer positions are adjusted. The vernier caliper only measures the change in the position ②. The maximum difference between the value and the tolerance is the coaxiality error. 5.6.3 The torque test is shown in the figure. The workbench for the short test is composed of a central indexing mechanism and a bracket. During the test, first press down the drill head shell, then clamp the larger part of it on the fully sensed mechanism, use a bracket to support the tail of the bow frame, and make the handle arm better than horizontal, and apply a heavy load of 360 degrees in the middle. After the test, the handle does not affect the other defects.
This test should be carried out for each ladder. 5.6.4 The test should be carried out in the vertical state, first apply a preload of N, and then gradually increase the load structure according to the rated load specified in Table 5, and start the test with the compression cover A of the drill L. After full rated load, unload to the expected load, the following formula should be used to calculate the average change of the load, which is in accordance with the table 5: YIKNEY KAa-
