b. Use anti-dissolution additive suitable for the oil.
2.3.2 HSM Jet Spindle Installation to CNC Machine
Fig. 28. HPC Jet Spindle on CNC machine
When the HSM Jet Spindle is mounted on the machine, the CNC machine spindle should be
stationary, except for tool check procedure or Z-offset measurement. In these cases, tool rotation
must not exceed 3,000 RPMs to avoid risk of breakage/injury.
To avoid 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 dened angle position.
2.3.3 Placement of HSM Jet Spindle in Toolholder
Caution: Deviation from these steps may lead to locking of the tightening nut to the HSM
Jet Spindle.
The HSM Jet Spindle only operates with a toolholder that has a coolant through channel.
To secure the HSM Jet Spindle in a toolholder: See steps in Figure 29.
Fig. 29. Placement of HSM Jet Spindle in toolholder
1. Use a standard toolholder with ER32 collet chuck.
2. Loosen the HSM Jet Spindle tightening nut 1.5 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 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.
WARNING! Using an automatic machine for locking, may cause damage to the Jet Spindle.

2.3.6 Tool Clamping and Runout Check (Recommendations)
The HSM Jet Spindle is designed to perform high speed operations with small diameter cutting
tools for very accurate machining.
It is very important to properly perform the instructions related to cutting tool setup, correct
clamping procedure and tool runout.
Standard clamping tools, such as ER11 spring collets and standard clamping accessories are used
on the HSM Jet Spindle.
To get a minimum runout value use ER11 SPR...AA or AAA spring collects with exact hole size.
According to ISO 15488, the collet runout tolerances should be checked as shown in the image.
Fig. 36. Optical runout testing Fig. 37. Manual runout testing
• HSM Jet Spindle body must remain static.
• Runout Is measured by rotating the shaft manually, or running an air supply through the
machine spindle.
2.3.7 Follow the 10% Rule
As the cutting tool enters the work piece, RPMs will be reduced due to load. The Jet Spindle RPM
value when working should not drop more than 10% of the RPM value registered at ‘idle speed’.
To Register Idle Speed:
1. Mount the HPC Jet Spindle on the machine with cutting tool installed.
2. Turn on uid pressure and note RPMs on the display monitor.
Example:
Improper conditions HPC Jet
• Spindle: TJS HPC ER32
• Application: Milling/Slotting
• Material: DIN ST 52-3
• Cutting tool: End Mill Ø2.0 mm (Ø.079”)
• No. of teeth: Z = 2
• Cutting conditions:
•Ae – cutting width = 2.0mm (.079”)
•Ap – depth of cut = 0.5mm (.02” )
•fz = 0.012mm/tooth (.0005” /tooth)
•Vc = 250m/min (820 SFM)
• N – Idle: 37,000 RPM
• RPM during machining: 29,600 RPM spindle overload!
In the improper example, following the 10% rule means that RPMs during machining should be
a minimum of 33,300 RPM, however RPMs are only 29,600. Therefore load on the tool should be
reduced by decreasing the cutting parameters; depth of cut (ap) and feed (Fz) should be lessened.

HPC HSM Jet Spindle HPC HSM Jet Spindle24 25
2.3.8 Recommended Cutting Conditions
• Monitoring RPMs during Jet Spindle operation is critical, to ensure optimum machining
conditions and to avoid damage.
• Cutting speed may be inuenced by material hardness, work piece topography and/or cutting
tool geometry. Refer to cutting tool manufacturer’s documentation.
• Dramatic uctuations of RPMS during Jet Spindle operation can indicate problems such as
inadequate coolant pressure or a broken cutting tool.
Jet Spindle Operating Guidelines
Cutting Conditions:
1. Monitoring RPMs during HPC Jet Spindle operation is critical to ensure optimum
machining conditions and to avoid damage.
2. Cutting speed may be inuenced by material hardness, work piece topography and
/or cutting tool geometry.
3. Dramatic RPM uctuations during HPC Jet Spindle operation may indicate
insufcient coolant pressure or a broken cutting tool.
Operating guideline tables for shoulder milling and slot milling operations using cutting
tool diameters of 2.0, 3.0 and 4.0 mm, are available on the Colibri Spindles website:
www.colibrispindles.com/product-literature/
3. Maintenance
3.1 Periodic Maintenance
The HSM Jet Spindle is free from periodic maintenance.
3.2 Battery Change on RPM Transmitter
The battery in the RPM transmitter mounted on the HSM Jet Spindle will lose power over time.
To change the battery, please proceed as in chapter 2 (Installation p.11).
3.3 Recommended Operating Environment
• Temperature range: 15-30° C.
• Max. altitude: 2000 m.
3.4 Spindle Storage
3.4.1 Spindle Pre-Storage
Before storing the HSM Jet Spindle:
• Clean the HSM Jet Spindle by air blowing for 10-15 seconds.
• Max. air pressure for cleaning (2 bar/30 psi) – DO NOT EXCEED 50,000 RPM.
• Disconnect the HSM Jet Spindle from the display device.
• Place the HSM Jet Spindle back in its case.
3.4.2 Recommended Storage Conditions
The HSM Jet Spindle should be stored to meet the following conditions:
• Sheltered from possible adverse weather conditions.
• Ideal Storage Temperature Range: 15° C to 27° C.
• Humidity Range: 30% to 60% relative humidity (RH).
WARNING! It is strictly prohibited immerse the HSM Jet Spindle in a uid bath.
Clean external adaptor and ER11 nut using alcohol and treatment with oil.
Clean internal shaft using air pressure only.
Any damage caused by one of the above “Warnings” will not be covered by the warranty.

HPC HSM Jet Spindle HPC HSM Jet Spindle26 27
4. Working with the HSM Jet Spindle
WARNING! Use the utmost caution when working with rotating tools.
The HSM Jet Spindle enables optimal cutting speed conditions for small diameter, solid carbide
tools requiring high RPMs.
The Jet Spindle rotates at its rated speed when idle. When the cutting tool enters the work piece, it
is expected that the rotation speed might slow down by several thousand RPM.
If the HSM Jet Spindle rotation speed drops by more than several thousand RPM, when the cutting
tool enters the work piece: refer to the 10% Rule (section 2.3.7) to adjust cutting parameters
accordingly.
Recommended Cutting Tool Parameters
HSM Jet Spindle Operating Data Model: HPC
Operating range of coolant pressure [bar] 20 - 70
Operating range of coolant ow rate [l/min] 16-22
Rotational spindle speed [Krpm]* 25 - 45
Optimum cutting tool diameter [mm]
Drilling 0.5 - 3.0
Milling 1.0 – 4.0
Maximum tool shank diameter [mm] 6.0
In order to take advantage of high speed machining, minimize cutting forces and reduce wear, tool
diameter should be selected according to the spindle speed (when possible).
• Always select the smallest tool diameter, according to the application requirements.
• Always select cutting tools in grades that are suitable for high speed machining.
4.1 Recalculation of Table Feed for HSM Jet Spindle
There are two calculation methods for table feed F [mm / min], with the HSM Jet Spindle:
• Existing machining process (transition from machining with a machine spindle to an HSM
Jet Spindle).
• New machining process.
4.1.1 Existing Machining Process
The feed per tooth fz remains constant while the table feed F increases in proportion to the HSM Jet
Spindle rotation speed.
The feed per tooth fz should remain constant while the table feed F changes.
Calculate the table feed F [mm/min] according to the following formula:
• F ≈ Ratio x F current
• F - New table feed
• Ratio - Ratio between the machine spindle speed and HSM Jet Spindle speed, (new speed divided
by the current speed).
• F Current - Current table feed with original machine spindle.
Example:
If using a machine spindle at 8,000 rpm, with a table feed of 160 [mm/min], and the HSM Jet Spindle
set to 30,000 rpm, then the new recommended table feed is as follows:
• New table feed = 30,000/8,000 x 160 = 3.75 x 160 = 600 [mm/min].
• In this example, the new table feed should be 600 [mm/min].
4.1.2 New Machining Process
Calculate the table speed, F [mm/min], according to the formula: F = n x z x fz
• Rotation speed – n [rpm] rotation speed for table speed calculation, can be determined only after
reading the actual rotation speed obtained when the tool has engaged the material.
• Number of teeth – z.
• Feed per tooth – fz [mm/tooth] , select according to tool vendor’s recommendations, taking into
consideration the machining material, application and the tool geometry.
Note:
First trial for both machining processes: It is recommended to increase table feed gradually.
