ASA (Air Supply Apparatus)
Variety of products to meet the requirement for low speed to high speed, for movable, for ASA, for high pressure coolant and etc are available. Special is available on request.
- Max. Speed：12,000 min-1（JHP3HS）
- Max. Coolant Pressure：1.0 MPa(JHP3AHPR)
Length of ASA
Example：JHP3-LR
LR=LS（Spindle Length）＋※＋A（Chuck Adapter）＋C（ASA Adapter）＋B（S.R. Bushing）＋E（Max.10mm）
※Dimension differs depending on the type of chuck. (Refer to the page of chuck.)

4 Layer ASA (For confirming workpiece seating)
Not only opening & closing jaws, air blow and/or coolant feed through the center bore of chuck, checking and confirming workpiece seated properly or not, is possible.
Air Supply Apparatus for High Pressure Coolant
JHP3AHPR(JHP3 High pressure coolant type)
4L3AHPR(4L3 High pressure coolant type)
| Model No. | Capability corresponding high pressure |
|---|---|
| JHP3AHPR | 1.0MPa |
| 4L3AHPR | 1.0MPa |
Increased capability to reduce the possibilty of penetration of coolant.
Can be used with CNC turning machines and grinding machines.
