5. 6. 1 The geometric accuracy of the overall post-analysis separation melon F disk should be GHT 46. 3. 5.6.2 The accuracy of the chuck should be as shown in the attached A5.7. The chuck should be tightened according to the product requirements, and the requirements of each part are normal. Table 5.B Limit speed GR/T434E.1-2002 The limit speed is the maximum speed allowed by the chuck. The limit speed should be determined by the manufacturer: The limit speed is determined by the conditions of the limit speed. At the limit speed, the actual tightening of the chuck should not be less than the limit speed of the chuck listed in Table 9. The outer end of the chuck is flush with the outer end of the chuck, and the waist is fixed in the random technical design. E. Test method. 1 Balance E.1.1 Static balance test t|| is a semi-balanced test as shown in the figure. It is installed on the pre-balanced mandrel, and the outer end of the lower end is flush with the outside of the chuck. Then it is placed on a type or holding half-balance frame to produce a small balance of the chuck. The balance quantity of the chuck can be obtained by the following formula: r=0/m
;
indicates the diameter of the center of mass from the center of rotation axis, and the effective value is (m): t
The concept of the semi-balance measured is correct. The mass is in grams (meters): The unit is dry grams (
