Control Abrasive Flow

This operation can be divided into the following:

  • Control abrasive flow by analog quantity

    It is used to control abrasive flow by adjusting the analog voltage output of Lambda terminal board that connects to the motor of abrasive valve.

  • Control abrasive flow by spindle

    It is used to control abrasive flow by bus control system sending pulse to control the speed of stepping motor that connects to the abrasive valve.

    It has more precise control and higher cutting precision.

Control Abrasive Flow by Analog Quantity

Before controlling abrasive flow by analog quantity, ensure parameter Abrasive Value Control Mode has been set to 0.

The relation among the actual output voltage of abrasive valve, the set output voltage and rate of analog output voltage is as follows:

Actual Output Voltage = Set Output Voltage × Rate of Analog Output Voltage

To control abrasive flow by analog quantity, do the following:

  1. Click Machine Tool → System Parameters. System Parameters dialog box pops up.

  2. Click Param → Operation → Manufacturer, input the manufacturer password, find and set the parameter Abrasive Value Output Voltage.

  3. To adjust the rate of analog output voltage, in Auto mode, drag S. R. (N) slider in machine tool control bar.

Control Abrasive Flow by Spindle

Before controlling abrasive flow by spindle, ensure the following:

  • The manufacturer parameter Abrasive Value Control Mode has been set to 1.

  • The drive subdivision is the same with the default value of internal parameter Pulse Output.

The relation among the actual motor speed, the set motor speed and the rate of motor speed is as follows:

Actual Motor Speed = Set Motor Speed * Rate of Motor Speed

To control abrasive flow by spindle, do the following:

  1. Click Params → Machine Tool, check Manufactory at lower left corner, find and set the parameter Stepper Motor Speed.

  2. To adjust motor speed, in Auto mode, drag S. R. (N) slider in machine tool control bar.
