2. Installation
2.1 Unpacking
Take the chuck out of the package box. At this time, be careful not to take out or lift it by hands.
This is because 8-inch or larger chucks weigh over 20 kg, and lifting such a heavy chuck may
cause damage to your lumbar or injury by dropping the chuck. Instead, break open the box and
screw an eyebolt into the screw hole outside the chuck. Then, use a chain block to lift the
chuck.
2.2 Accessories
The package box contains the accessories besides the chuck itself.
Please refer to the section 6.6 “Accessories” for particulars.
2.3 Preparations for Installation
Except the direct-mount chuck of H032M-A 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 pipe, 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 pipe.
2.4 Stroke Control
For type A spindle mounting H032M chuck, the cylinder stroke of the rotational cylinder and the
plunger stroke of the chuck must be equal.
If the rotational cylinder stroke is longer than the plunger stroke of the chuck, the former must
be adjusted to the latter. As the ways to control the cylinder stroke are different, depending on
types and sizes, consult Howa for necessary information before the stroke adjustment.
Use the eyebolt when installing or removing the chuck.
(To lift a 6-inch chuck, use a suspender belt. To lift an 8-inch or
larger chuck, use an eyebolt.)
You may drop the chuck or suffer from lumbar injury due to excessive
load.
The user must fabricate a connecting pipe in accordance with the
lathe used and the chuck, which has been selected.
It is extremely important that connecting pipe be sufficient to assure
rigidity and strength.
Insufficient strength or rigidity will cause breakage of the connecting
pipe and instantaneous loss of gripping force to the chuck. This may
cause the work piece to be released during operation.
