The MICRO 90 Jet Spindle driven by high pressure coolant, with a solid shell of titanium and assembled from only six parts, is built for High RPM , accurate work in small and difficult-to-reach spaces .
.
The MICRO 90 Jet Spindle enables speeds from 35,000 to 53,000 rpm while the main machine spindle remains idle. The MICRO 90 Jet Spindle is ideal for a wide range of semi-finish and finishing applications by use of small cutting tools intended for milling, drilling, thread milling, engraving, chamfering and deburring.
There are prerequisites for using the Microjet 90 Jet Spindle on CNC Machines.
- Coolant flows through the main CNC machine spindle
- Minimum coolant pressure, at main spindle outlet of 20 bar
- Maximum coolant pressure, at main spindle outlet of 40 bar
- Minimum flow rate of 10 liters per minute
- Filter element of maximum100 micrometers
- An active mist collector
- When using emulsion coolant, use an anti-foaming agent additive suitable for emulsion.
- When using oil-based coolant, the high-pressure increases the number of oil fumes. Therefore, it is recommended to use an appropriate means of fire protection and to use anti-dissolution additive suitable for oil.
I would like to remind you to download the ISCAR World app which features the revolutionary NEO-ITA for achieving optimal machining result.
