Do I need a high pressure system to run the CoolSpeed® mini?

It is not strictly necessary to have a high pressure system to run the CoolSpeed® mini. However, a high pressure system will offer the opportunity to utilize the maximum speed and power available. The CoolSpeed® mini can operate between 150 psi and 870 psi of coolant/oil pressure. Care should be taken to ensure that the necessary volume flow is achieved by the pump.


What is the maximum drill size that may be used with the CoolSpeed® mini?

The material and drill specifications are critical to the determination of maximum drill size, with cutting speed (SFM) being the most common limitation.  


For soft materials, we recommend drills up to 5 mm.

For hard materials, we recommend drills up to 3 mm.

The feed rate in drilling applications is extremely important and should be optimized according to machine and tool parameters.


Is it possible to re-use the bearings or turbine when replacing the cutting tool?

No. If attempting to re-use bearings or turbine, it may lead to poor machining results and tool breakage.


Is the CoolSpeed® mini damaged during a crash?

No. Normally, the CoolSpeed® mini in not affected by a crash. The tool and bearings will be damaged, so installing a new cutting tool with new bearings and turbine will restore performance.


Do I need a Pressure Gauge?  Why can’t I just use the one on my machine?

The rotation speed is a function of the coolant/oil pressure at the CoolSpeed® unit while in operation. The machine’s pressure gauge is typically installed near the coolant pump and cannot account for the pressure drop throughout the machine. Using the reading on this gauge would give an inaccurate estimate of the pressure flowing through the CoolSpeed® mini, leading to incorrect tool rpm calculations.


Do I need a different CoolSpeed® mini housing for each tool shank/bearing size?

No. Every CoolSpeed® mini housing supports any of the offered Replacement kits and the operator may change between tools of different sizes as needed with the CoolSpeed® mini housing still installed in the tool holder.


What is the minimum filtration requirement for the CoolSpeed® mini?

The filtration system installed on the machine will be sufficient for the CoolSpeed® mini. It is recommended to clean the filters according to the maintenance procedures and intervals of the machine manufacturer. A decrease in coolant pressure due to clogged filters will negatively affect the CoolSpeed® mini’s performance.
