6.2.1 Radial runout of the circumferential cutting edge to the inner hole axis Figure 1, install the saw blade milling cutter or screw groove on the boss core shaft (the core shaft and the cutter inner hole should be matched), place the dynamic measuring instrument on both sides, and the indicator probe vertically touches the inspected part, rotate the core shaft, and the cutter rotates one circle. The difference between the maximum and minimum values ​​of the indicator pointer is read as the rotation runout, and the maximum value of the absolute value of the difference between adjacent inner holes is taken as the adjacent inner hole runout value. 6.2.2 Side runout of the end face facing the inner hole axis Figure 1, install the saw blade milling cutter or screw groove on the boss core shaft (the core shaft and the cutter inner hole should be matched), and use the dynamic measuring instrument JB/T 10231.13—2002
The measuring head of the indicator shall directly touch the part to be inspected, the mandrel shall be rotated, the cutter shall rotate a circle, the maximum value of the difference between the maximum and minimum readings of the indicator gauges on the two end blades shall be taken as the surface runout value, and the maximum value of the difference between the adjacent potential difference values ​​on both sides of the free blades shall be taken as the circular runout value of the adjacent teeth.

? The milling thickness and the outer diameter of the working part shall be in accordance with the provisions of 10.2 of JB/T10231.1-2001. The inner hole of B shall be in accordance with the provisions of chapter 1 of JB/T10231.J2001. 9 Angle, back angle 9.1 Testing location The front and back of the circular teeth of the lead cutter and screw milling cutter. 9.2 Testing method 9.2.1 Front angle See Figure 2. Place the working surface of the angle support ruler against the adjacent tooth top of the effective cutter tooth, adjust the measuring tool so that the workpiece surface of the front angle ruler is in contact with the tooth to be measured, and make the working surface of the back ruler contact with the tooth of the cutter tooth, and then the front angle value can be read. 92.2 Back angle wwW.bzxz.Net
See Figure 2, place the lower working surface of the angle support ruler against the adjacent tooth of the measuring cutter tooth, adjust the measuring tool so that the lower proof of the back angle ruler is in contact with the back force of the measuring cutter tooth, and make the front angle ruler working surface contact with the top of the measured cutter tooth, then the back angle value can be read, set: when there is a dispute, put it on the universal tool under the microscope, 9.3 Check the book tool

See Figure 3 for the back angle inspection. When testing on the special measurement, place the knife level on the special test seat for the side angle, press the indicator on the effect to take the value, and measure at 2 to 3 approximately equal positions. Take the smallest value of the indication these times, which is the value of the tread angle. Use the same method to measure the value of the side clearance angle of the other side, and take the smallest value of the indicator readings on the two end surfaces as the side clearance value.
