Product description
The GH-6020NT is a compact CNC press brake from GHBM's NT Series. It has a working force of 60 tons and a maximum bending length of 2000 mm. Its six NC axes are Y1, Y2, X, R, Z1 and Z2, which control ram movement and backgauge positioning.
The machine has a 440 mm daylight opening, a 180 mm ram stroke and a 300 mm throat depth. It is controlled by a GHBM-700T CNC controller with a 15-inch Techmation display. Its configuration includes a 5.5 kW Techmation main servo motor, a DPT hydraulic system, an OPKON closed-loop position sensor, SKF/NOK cylinder seals and a GHBM double-side quick-release clamp.

Maintenance & care
General recommendations for servo-hydraulic CNC press brakes. Follow the manufacturer's manual for model-specific requirements.
- Daily cleaning: Remove metal debris and dust from the worktable, tooling, clamps and backgauge area.
- Hydraulic oil checks: Check oil level and condition regularly. Replace oil and filters at the manufacturer's recommended intervals.
- Leak and seal inspection: Inspect the cylinders, hoses and fittings for leaks, and replace worn seals promptly.
- Tooling inspection: Check punches, dies and quick-release clamps for wear, damage or incorrect seating.
- Lubrication: Lubricate backgauge guides, screws and other moving parts as specified by the manufacturer.
- Axis and backgauge checks: Watch for abnormal noise, vibration, positioning drift or unexpected movement.
- Electrical inspection: Check cables, connectors, switches and the control panel. Only qualified personnel should do electrical work.
- Safety checks: Before production, verify that the foot switch, emergency stops and safety devices work correctly.
- Periodic servicing: Schedule manufacturer-recommended inspections and keep a log of maintenance and faults.
