Nakanishi HTS1501 Operation Manual

Ultra-precision High-Speed Air Turbine Spindle
HTS1501S
Thank you for purchasing the Ultra-Precision, High-Speed Air Turbine, HTS1501S. HTS1501S was
designed for use on machining centers without rotating the machine s main spindle. HTS1501S uses
an Ultra-precision collet system and is ideal for use with small diameter end mills in mold making
applications. The Air Line Kit(with Lubricator) is used to drive HTS1501S.
Please read this Operation Manual carefully prior to use.
Cautions for handling and operation
1
■Read these cautions carefully and only use in the manner intended.
■Safety instructions are intended to avoid potential hazards that could result in personal injury or
damage to the device. Safety instructions are classified as follows in accordance with the
seriousness of the risk.
Class
A hazard that could result in bodily injury or damage to the device if the
WARNING
safety instructions are not followed.
！
A hazard that could result in light or moderate bodily injury or damage to
CAUTION
！
the device if the safety instructions are not followed
WARNING
！
TS1501S is not a hand tool. It is designed to be used on machines.
①
Never rotate the main spindle of the machining center.
②
Never touch the motor, spindle or cutting tools when the spindle is rotating.
③
Always wear safety glasses. Everyday eyeglasses only have impact resistant lenses,
④
they are not safety glasses. Also use a dust or face mask whenever the motor is
running.
Do not apply excessive force(deep per pass cuts, high feed rates) . This may cause
⑤
tool slippage or spindle damage.
Do not use unbalanced or low precision tools.
⑥
Use less than 1.0 square end mill, less than R0.5
⑦ φ ㎜
grindstone for tools to avoid danger.
CAUTION
！
Do not drop or hit TS1501S, the shock can damage internal components.
①
Check that the collet has been securely tightened prior to each use.
②
Always clean the chuck. If ground particles or metal chips stick to the inside of
③
spindle or the chuck, this will cause damage to the chuck or spindle and loss of
precision.
Do not over tighten the chuck. This will cause spindle damage.
④
An Air Line Kit is necessary for use with TS1501S.
⑤
The motor speed will be decreased and the lifetime will be shortened without the use
of an Air Line Kit.
Always drain water from the air filter(Air Line Kit). Water or ground particles will
⑥
cause rust or damage to the internal parts of the turbine.
Select suitable products or tools for the application. Do not exceed the capabilities of
⑦
the spindles or cutting tools.
Stop working immediately when abnormal rotations or unusual vibrations occur.
⑧
If the spindle has not been used for a long period of time, in excess of one month ,
⑨
start at a low air pressure and run the spindle as slowly as possible. Over a period of
15-20 minutes, raise the air pressure and spindle speed incrementally until you reach
the maximum allowable speed. Check for abnormal noises, vibration or heat.
Check if tools or chucks are damaged before working.

Replacement of tools
4
Replace the tools according to the following procedure.
①Place the provided 8㎜ spanner on the spindle shaft to fasten.
②Place the provided 11㎜ spanner on the
chuck nut, and turn it counterclockwise to
loosen the chuck. And pull out the tool.
(The chuck nut will loosen but the collet will
not release the tool after one turn, turn it
more, and the chuck will open.)
③Shorten the length of max. tool mounting as
possible when inserting another tool.
④Turn the chuck clockwise to fasten the tool.
C AUTION
！
Never install a collet into the spindle quill without first assembling it in the chuck nut.
Do not tighten the collet without mounting a cutting tool or test bar as this will result
in a damage to the collet, spindle and collet nut and make it impossible to remove the
collet.
Replacement of the chuck
5
Replace the chuck according to the following
procedure.
①The chuck nut is loosened together with the tool
according to the 4.Replacement of Tools
procedure above. And unscrew the chuck nut
and remove the collet and chuck nut.
Then remove the tool from the chuck. (
②Hold the chuck nut in one hand and push the
collet diagonally toward the spanner flat to
remove the collet from the chuck nut (
③The new chuck can be attached by inserting the
new chuck diagonally toward the spanner
