(2) Coolant joint
(a) Thrust load of through coolant
When spindle through coolant is used, the thrust load works between the spindle and the motor at the position
A, and between the motor and the rotary joint at the position B in the figure below. Setting the diameter of the
pressured area of the coolant joint attached to the end of the motor shaft appropriately makes the thrust load at
the position B slightly larger than at the position A, which is effective for coolant pump pulsation.
(b) d (the diameter of the pressured area of the coolant joint)
The following are the recommended diameters of the pressured area of the coolant joint installed at the end of
the motor shaft.
(Note)
Effective when the coolant pressure is 6.8MPa or less (Contact the manufacturer if it exceeds
6.8MPa)
(Note) Without a coolant joint, the thrust load is applied to the motor side by coolant pressure. An excessive
thrust load on the spindle motor may lead to abnormal noise or vibration, or shorten the motor life.
We recommend using an appropriate coolant joint.
