CNC Press Brake with T8 CNC Controller: Installation and Operation Guide

1.Hydraulic Oil Filling

  ●Oil Selection: Use anti-wear hydraulic oil suitable for ambient temperatures. For standard conditions, 46# anti-wear hydraulic oilis recommended.

  ●Oil Volume: Fill the tank to 80%-90% capacity.

Key Steps:

  ●0:31: Connect the foot pedal switch by aligning the aviation connector’s bayonet and tightening its nuts.

  ●0:53: Connect the power cable based on the machine’s total power. Attach the three-phase wires to the electrical cabinet’s power switch.

  ●1:37: Turn on the electrical cabinet’s power switch.

  ●1:57: Verify all emergency stop buttons are released.

  ●2:07: Start the oil pump via the screen button, then press the emergency stop. Confirm the main motor rotates clockwise(check the motor’s direction sticker).

    ○If counterclockwise, swap two phase wires and retest.

2. Machine Leveling

3:13: Use a spirit level to measure the worktable’s horizontal accuracy. Adjust the base plate bolts (place steel plates underneath for stability).

3. T8 System Interface Functions

  ●3:37: Oil Pump Control: Hold for 3 seconds to start/stop the motor.

  ●3:43: Upper Die Selection/Editing: Match the library to actual tools.

  ●3:48: Lower Die V-Groove Editing: Input actual groove sizes (e.g., 8× sheet thickness).

  ●3:55: Material Thickness/Length Input: Enter measured values.

  ●4:03: Angle Display Toggle: Switch between bend angle and Y-axis value.

  ●4:07: Bend Angle Setting: Input desired angle (e.g., 90°).

  ●4:12: Angle Correction: Compensate deviations (e.g., enter –1.5° for a 91.5° result).

  ●4:19: X-Axis (Backgauge) Control: Set positions for internal/external dimensions.

  ●4:30: Slider Return: Move to upper dead center.

  ●4:38: Program Execution: Press "START"; displays "STOP" during operation, "OK" when complete.

  ●4:48: Pressure Delay: Set to 3.0–5.0 sec for optimal bending.

Operational Modes:

1.Inch Mode: Foot pedal controls incremental movements.

2.Single Cycle: Completes full bend cycle (fast/slow descent + pressure).

3.Continuous Mode: For testing (not production).

4. Tooling Setup

  ●6:28: Upper Die Selection: Measure and input actual height.

  ●7:14: Lower Die V-Groove:

    ○Rule: Groove width = 8× material thickness (e.g., 8mm for 1mm sheet).

    ○Replacement: Loosen screws, flip the die, and align the new groove with the upper blade.

5. Calibration & Testing

  ●14:15: Angle Calibration:

    ○Test bend (e.g., 1mm iron plate, 90° target).

    ○If error >5°: Manually adjust Y-axis (password: 0313), fine-tune in 0.5–1.0 increments.

  ●15:52: X-Axis Calibration: Compensate measured dimensional errors.

  ●17:47: Program Validation: Check each bend against drawings; save after alignment.

  ●22:47: Synchronizing Left/Right Angles:

    ○Adjust the sync shaft behind the slider (rotate 5 turns/test until angles match).

6. Pressure Adjustment & Alarms

  ●26:21: System Pressure: Adjust the remote valve clockwise while pressurized.

  ●Common Alarms:

    ○Oil Pump Not Started: Press the start button.

    ○Slider Not at Top: Return to upper position before operations.

    ○Servo Alarm: Check for mechanical obstructions (consult JUGAO if unresolved).
