③ How to fabricate the Split Type Holder
(1)
Roughly process (carve) the inside diameter of the Split Type
Holder.
(2)
Cut a slit. (Ex. Slit 2mm)
(3)
Twist the Screw for Removal and Broaden the Slit Area.
(4)
Insert spacer (ex t = 2mm) into the Slit Area.
(5)
Loosen the Screw for Removal, and tighten the Fastening Bolt
with the specified torque.
(6)
Finish machining the Split Type Holder so that the inside diameter
of the Split Type Holder is motor spindle's outside diameter
depending on the i-Speed3 motor / spindle model (Refer to Table 2).
The correct tolerance range for the holder is - 0.01mm to - 0.015mm
and a roundness and cylindricity of less than 5μm.
(7)
When inserting the motor spindle loosen the Fastening Bolt and
twist the Screw for Removal, and broaden the Slit Area.
