1.5. Main Features
The HSM Jet Spindle spindles are best used when high RPMs is required for small diameter tools on limited RPM CNC
machines. The system utilizes the CNC machine tool’s existing coolant supply driven by a high pressure pump (minimum
20 bar) as an energy source to rotate a turbine up to 60.000 RPM. The HSM Jet Spindle can be supplied either as right-
hand or left-hand option.
The HSM Jet Spindle is not intended to replace the CNC machine spindle, but rather to upgrade the existing
CNC machine, providing improved performance, faster machining, better surface quality, and extended tool life.
The new spindles can be used for semi-finish and finish machining applications such as milling, drilling, and jig grinding.

1.5.4 Integrated Coolant Nozzle System
The Integrated coolant nozzle system provides 3 main advantages:
- Direct jet coolant application
- Better and faster chip evacuation
- Prevents tool thermal shock

1.5.5 Tool Clamping
The HSM Jet Spindle is compatible with ER11 collet chuck.
The assembly of rotating elements (collet, nut and tool) must be balanced to a G2.5 at 40,000 RPM.
We recommend that you use ER 11 high precision spring collets.
When longer overhang is required, 10 & 25 mm long ER11 thermal shrink collets are available.

2.3.1 Prerequisites for the CNC Machine
1. Coolant flow through the main CNC machine spindle
2. Minimum coolant pressure, at main machine spindle outlet: 20 bar
3. Maximum coolant pressure, at main machine spindle outlet: 40 bar
4. Minimum flow rate: 12 L/min
5. Minimum coolant filtration level: 100 µm
6. An active mist collector
7. With the emulsion coolant, use an anti-foaming agent additive suitable for your emulsion to prevent foaming.
8. Use emulsion coolant with oil percentage higher than 4%
9. With oil coolant, the high pressure increases the amount of oil fumes:
a. Use appropriate means of fire protection and extinguishing.
b. Use anti-dissolution additive suitable for your oil.

2.3.2 HSM Jet Spindle Installation onto the CNC Machine
While the HSM Jet Spindle is mounted on the machine, the CNC machine spindle should be stationary, except for tool
checking procedure or Z-offset measurement. In those cases it must not exceed 3000 RPM, or risk breaking/injury.
To avoid the CNC machine spindle rotation during the HSM Jet Spindle operation use the correct
software M-code to lock the Spindle orientation.
For example: „M19“ code locks the spindle in a defined angle position.
Before installing a HSM Jet Spindle with a filter on the machine spindle, make sure that the filter is clean.

2.3.3 Placement of HSM Jet Spindle in the Toolholder
Caution: Deviation from these steps might lead to locking of the tightening nut to the HSM Jet Spindle.
The HSM Jet Spindle will only work with a toolholder that has a coolant through channel.
To fix the SpinJet Spindle in a toolholder: See steps from left to right in Figure 29.
1. Use a standard tool holder with ER32 collet chuck
2. Loosen the HSM Jet Spindle tightening nut 1.5 full turns
3. Insert built-in ER32 taper shank into ER32 collet chuck until the HSM Jet Spindle tightening nut will be placed on the
toolholder
4. Fasten the HSM Jet Spindle tightening nut onto the toolholder, without turning the HSM Jet Spindle relative to the nut
5. Fasten the HSM Jet Spindle tightening nut to clamp the HSM Jet Spindle and the toolholder together with an ER 32
spanner, use hand force only
