Circumference or diameter.
6.2 Testing method
6.2.1 Circumferential blade radial runout
The testing method of the radial runout of the cutting edge relative to the cutting edge is shown in Figure 1 and Figure 2. The cutter is placed on a V-shaped iron block, and the end is pre-set. The ball is added between the center and the position of the end. The probe of the back gauge is placed close to the circumferential blade of the cutting tool. The reading of the gauge of the cutting edge .E is read and the difference is taken. 6.2? End blade runout
The end blade line is about the same as the end blade line. Method for testing runout: For straight groove cutters with center holes and chain groove milling cutters with jointed shanks, see Figure 2. Place the jointed cutter on a V-shaped iron plate, place a positioning block on the end of the shank, add a silver ball between the center of the shank end and the positioning block, and measure the indicator head at the end. Read the small dial readings on the two cutting edges separately and take the difference. For straight chain cutters with reversed shanks, follow the corresponding method and the runout can be directly measured. For chain cutters without center holes, measure the runout of the end face of the simple cutting edge against the axis of the main body. The detection can be seen in Figure 3: Put the chain on the stopper, and the end can be placed against a positioning support. The measuring head of the chain tip touches the outside of the cutting edge. Read the readings of the indicator on the cutting edge respectively, and the value is half of the value.

7.2 Inspection method
The diameter inspection shall be in accordance with the provisions of 10.1 in JB/T10231.1-2001 and JB/T10231.14-20D2
The inspection is divided into two parts: measure point A near the center of the blade, measure points approximately distributed in the middle and rear, and take the absolute value of the gains of points 1 and 1 and the absolute value of the difference between the readings of points A and C respectively. For straight shank milling cutters with a diameter less than 16mm and a diameter less than 72mm, only points 4 and C are allowed to be measured, see Figure 44. Figure 4 Method for checking the diameter difference of the working part 7.3 Testing instrument The value of the measuring scale is 0.01mm or 0.001mm. 8 The shank diameter of the straight shank milling cutter shall comply with the provisions of JB/T10231.1-2001.1 9 The taper shank of the Mohs shank milling cutter shall comply with the provisions of JB/T10231.1-2001.6 10 The total length and the length of the working part shall comply with the provisions of JB/T10231.1-2001.10.3. 11 Hardness shall comply with the provisions of JB/T10231.1-2001.11.3. 12 Ladder and packaging || tt || According to JB/T1023[.1-2001 award 13 Zhuo, Ben 14 Xin regulations 3
