2.2 Accessories
The package box contains the accessories besides the chuck itself.
Please refer to the section 6.5 “Accessories” for particulars.
2.3 Preparations for Installation

□
type, a chuck adapter is needed to install the
chuck onto the lathe spindle. Contact us if you need information on how to design a chuck
adapter.
In addition to the chuck adapter, a rotating cylinder, a cylinder adapter, a connecting rod, and
either a hydraulic or pneumatic pressure source are required to operate the chuck. However,
please refer to the Rotating Cylinder Instruction Manual for what pertains to them.
We, upon request, will review drawings for the connecting rod.
2.4 Stroke Control
Although the rotating cylinder stroke of the rotating cylinder
should not be necessary controlled according to the chuck
plunger (/draw sleeve) stroke, adjust the draw screw so that the
draw sleeve contacts the back plate of the chuck.
2.5 Installing Procedure
2.5.1 Before Installation
After taking the chuck out of the package box, wipe off all anticorrosive oil clinging to it with a
cloth permeated with cleaning oil.
2.5.2 Installing Chuck Adapter
Install the chuck adapter on the spindle end face.
Then the chuck installing socket (C) and datum face should be machined in place.
The clearance of the chuck adapter in relation to the chuck installing socket (C) should be
0.040
～
0.050 mm in diameter.
The user must fabricate a connecting rod in accordance with the
lathe used and the chuck, which has been selected.
It is extremely important that connecting rod be sufficient to assure
rigidity and strength.
Insufficient strength or rigidity will cause breakage of the connecting rod
and instantaneous loss of gripping force to the chuck. This may cause
the work piece to be released during operation.
