How to Measure the Coolant Pressure

The CoolSpeed® Flex rotation speed depends on the coolant pressure. Therefore, it is important to adjust the coolant pressure as needed for the application. There are two options to measure the coolant pressure.
Option 1

Preferred option, as the measurement of the pressure is close to CoolSpeed® Flex.

Measure the Coolant Pressure 2
Option 2

Alternative, if there is no possibility to place the manometer inside the operation area. With this option, the speed determination is less accurate than option 1.

Adjust the Rotation Speed

  1. Adjust CoolSpeed® Flex to 5 Jets
  2. Switch the coolant pressure on
  3. Read the pressure and rotation speed from the Pressure Gauge or using the CoolSpeed® App
  4. Adjust the coolant pressure via the pump control until the desired rotation speed is reached
  5. If the desired speed cannot be reached: Switch the coolant pressure off, reduce the number of jets and repeat from point 2

Note:
The inner diameter of the coolant supply pipe should be at least 4 mm.
The rotation speed refers to the idle speed.
The operation speed is approx. 10% lower depending on the load on CoolSpeed®.

Assembly of Bearings and Turbine onto the Cutting Tool

Note: The tolerance of the tool shank should be h6 or better.
