There are three main factors that we are looking to achieve:
The rpm developed by the angle head is a function of coolant flow rate (litres per minute). The Titespot® angle head will rotate at approximately 238 rpm per litre of flow.
The torque developed by the angle head is a function of coolant pressure (Bar/PSI). Under test conditions the positive displacement ball piston motor develops .03 Nm of torque per bar of coolant pressure.
This is a direct correlation of flow rate and pressure. As a guide, in steel the metal removal rate is 22cm3 of material per minute per kilowatt of power generated.
We recommend a 50 micron pre-filter followed by a 10 micron filter, for best results this should be on the pressure side of the system.
Good filtration is also recommended on your compressor driving the air hose and air blast system. Most machine tools will spin the tool at every tool change and machinists will also tend to use air hoses to clear the tool when storing away.
The figures quoted opposite apply to standard product. For 'heavy duty' or more demanding cutting operations that may benefit from higher torque at lower speeds, gear reducers and special motors can be offered.
