4.! The finger joint is not allowed to have cracks, spots, corrosion, abrasion and other defects that affect the performance. 4.2 The surface roughness of the finger joint knife is in accordance with the provisions of GA/T1131. The maximum allowable value meets the following requirements: a) The front is _0.4μ㎡
b) The blade surface and the back are R0.8m.www.bzxz.net
c) The ratio of the aperture surface and the two supporting end faces is 1.25=m. 43 The position of the finger joint is as specified in Table 2. Table 2 The position of the finger joint is as follows:
The radial load of the blade of the finger joint to the hole diameter axis and the symmetry of the center plane of the body thickness of the two joints Note: The radial load of the blade of the finger joint to the hole diameter axis and the symmetry of the two joints to ... 4.4 The cutting part of the finger joint is made of YG8 in accordance with YS/400 or other hard metal with material performance not lower than 11. The material of the finger joint is made of 45 steel in accordance with GB/T699 or other materials with material performance not lower than 4. The finger joint should be statically balanced, and the maximum allowable unbalance is 80, mm, 4.6 The shear strength of the finger joint The speed should not be lower than 120MPa. 4.7 The maximum working speed of the finger joint knife should be marked, and the maximum working speed is 7000r/mjm. 4.8 The safety of the finger joint knife should also comply with the relevant provisions of B6113. 5 Test methods and inspection rules
5.1 The performance test of the finger joint knife should be carried out on the machine with the standard of comfort accuracy, and all safety requirements shall be determined in accordance with GR1255. 5.2 The test material is a medium-hard seat material with a water content of 12%~15%. 5.3 The test cutting agent specification is in accordance with Table 3.

Test method for position tolerance of finger joints of single piece of hardwood woodworking A1. Test method for position tolerance of finger joints of single piece of hardwood woodworking alloy is shown in Table A1. Table A1
According to the item
Tolerance of finger joints
Tolerance of finger joints

Tolerance of support faces
Tolerance of hole diameter ... |tt||Parallelism inspection method of supporting end
Put the finger joint on the circular motion, press it with a
flange, put the dial indicator contact heavily against the top edge of the knife tooth, and the finger edge rotates one circle. The maximum and minimum values ​​of the radial direction of the finger joint are restored by percentage.
The surface of the dial indicator is in the force tooth
. , the finger connection is able to turn - feel, read the stop
dial indicator value; since the height is not
, use the same method to measure the knife teeth on the other side
the same position full of the dial indicator value, the difference between the maximum value and the minimum value of the two dial indicators refers to the symmetry of the blade
. Place the dial indicator contact vertically on the central part of a supporting surface of the finger
door, and use the finger to hang the knife and turn it. The whole of the maximum value and the minimum value read on the dial indicator is the method of inspection for the surface of the plate, which belongs to the anti-movement
super violation. ||The supporting belt of the joint shall be square,
the horizontal effect shall be in the flat surface.
the lead head of the dial gauge shall be against the support surface 1 of the finger joint knife,
measure the dosage in two perpendicular directions, the difference between the maximum and minimum number of teeth of the dial gauge is the parallelism of the finger joint knife
