Product description
The GH-1025PC is a CNC press brake from GHBM's PC Series. It has a working force of 100 tons and a maximum bending length of 2500 mm. Its seven NC axes are Y1, Y2, X, R, V, Z1 and Z2, which control ram movement, backgauge positioning and the worktable.
The machine has a 460 mm daylight opening, a 200 mm ram stroke and a 400 mm throat depth. The hydraulic system is driven by two 3.8 kW main servo motors, with an oil volume of 38 L × 2, and uses a German ECKERLE hydraulic pump and a Rexroth proportional valve. It is controlled by a GHBM-940T CNC controller with a 21.5-inch Techmation display. Other components include Techmation servo motors and drives, an OPKON closed-loop position sensor, SKF/NOK cylinder seals and an Amada-equivalent 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 the oil level and condition in both 38 L oil volumes regularly. With smaller oil volumes, oil condition and temperature matter more, so replace oil and filters at the manufacturer's recommended intervals.
- Leak and seal inspection: Inspect the cylinders, pumps, proportional valve, hoses and fittings for leaks, and replace worn seals promptly.
- Motor checks: Watch both main servo motors for abnormal noise, heat or vibration.
- 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.
