What Coolant Pressure and Flow Are Required to Operate an Angle Head?

Speed (rpm) developed by the angle head is a function of the coolant flow rate, torque is a function of coolant pressure, and horsepowerkilowatts is a function of both.

The angle head will rotate at about 900 rpm per gallon238 rpm per liter of flow.

Under test conditions, the motor develops 1.9 inch pounds of torque for each 100 psi of coolant pressure.Under test conditions, the motor develops .03 Nm of torque per bar of coolant pressure.

To calculate horsepowerkilowatts see the Angle Heads Performance Data page.

As a rule of thumb, in steel the metal removal rate is one cubic inch of material per minute per horsepower22 cubic cm of material per minute per kilowatt. For a more thorough explanation, see How Fast Can I Machine?".

Note: the above calculations and formulas apply to our standard product. For "heavy duty" applications that might benefit from higher torque at lower speeds, we offer gear reducers and special motors. Call our Application Department for more information on these options.
