Page 15: Relationship Between Gripping Force And Rotation Speed
As the rotation speed becomes higher, the centrifugal force of the jaw increases and the gripping force lowers. The curves displayed in Fig. 6, Fig. 7 shows relationships between the rotation speed and the centrifugal force when using the standard soft jaw. The centrifugal force differs significantly depending on the size and shape of the top jaw and the attaching position, therefore, when the rotation speed is high, actual measurement using a Kitagawa gripping force meter is required. ・B-200 type B-205 B-204 28.5... - Page 16 B-210 B-212 Input force Input force Limit Limit 1000 2000 3000 1000 2000 3000 4000 5000 4200 3300 Rotation Speed（min - Rotation Speed（min - ） ） B-215 Input force Limit Fig.6 1000 2000 3000 2800 Rotation Speed（min - ） ・BT200 type BT205 BT204 Input force Input ...

Page 17: Relationship Between Gripping Part Center Height, Static Griping Force And Input Force / Relationship Between Top Jaw Mass Moment And Gripping Force Loss
DANGER ・In the case of processing a considerably unbalanced work, lower the rotation speed. The work will fly out and this is dangerous. ・Vibration is generated if there is unbalance due to the work and the jig, etc. Vibration decreases process precision and shortens the working life of the chuck, even possibly breaking it. Correct the unbalance by using a balance weight, etc., or lower the rotation speed for use. ・In the case of heavy cutting at high rotation speed, vibration is easily generated in the same manner as the unbalance of the chuck, therefore, set the cutting conditions appropriate for the dynamic gripping force and machine rigidity. 3-3 Relationship between gripping part center height, static griping force and input force / Relationship between top jaw mass moment and gripping force loss If the gripping part center height of the used top jaw (dimension H in Fig. 8) is higher than the gripping part center height of the standard soft jaw, a large load is applied to the master jaw, T nut, jaw attaching bolts, etc. To prevent these parts from being broken, it is necessary to use the machine by using a lower input force than the allowable maximum input force. Additionally, if the top jaw is larger and heavier, the centrifugal force generated at the top jaw will increase. It is necessary to examine the dynamic gripping force considering the centrifugal force and to use the machine at a rotation speed that can withstand the cutting force.

- Page 21 The required static gripping force and input force required at the rotation speed in use are predicted from Fig.9, Fig 10, however, it contains a number of hypothetical conditions. Therefore, it is necessary to only use these as reference, and the processing conditions must be determined after trial cutting without fail. DANGER ・Reduce the allowable maximum input force of the 2 jaw chuck by 2/3 in comparison with the 3 jaw chuck. (Refer to Table 3) Otherwise the chuck will break, the work will fly out and this is dangerous. ・In the case of inside diameter gripping, keep the input to 1/2 of the allowable maximum input or less. In the case of inside diameter gripping, the length of engagement of the master jaw and the dovetail groove is shorter when compared to the outside diameter gripping, therefore, the chuck will break, the work will fly out and this is dangerous. ・In the case of using only 1 jaw for gripping reduce the input force by 2/3 or more with 3 jaw chuck. If 2 jaws are used for gripping reduce the input force by 1/3 or more with 3 jaw chuck. If 1 jaw is used for gripping reduce the input force by 1/2 or more with 2 jaw chuck. If it is used without lowering the input, the input which is normally applied evenly onto 3 of the jaws is concentrated onto 1 or 2 of the jaws. Otherwise the chuck will break, the work will fly out and this is dangerous.
