Product description
The GH-4042DS is a heavy-duty CNC press brake from GHBM's DS Series. It has a working force of 400 tons and a maximum bending length of 4200 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 600 mm daylight opening, a 300 mm ram stroke and a 450 mm throat depth. The hydraulic system is driven by two 15 kW main servo motors, and the specified oil volume is 120 L × 2. It is controlled by a GHBM-940T CNC controller with a 21.5-inch Techmation display. Its configuration includes Techmation servo motors and drives, a DPT hydraulic system, an OPKON closed-loop position sensor, SKF/NOK cylinder seals and a GHBM single-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 full length of the worktable, tooling, clamps and backgauge area.
- Hydraulic oil checks: Check the oil level and condition in both 120 L oil volumes regularly. Replace oil and filters at the manufacturer's recommended intervals.
- Leak and seal inspection: Inspect the cylinders, pumps, hoses and fittings on both hydraulic circuits 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 along the full bending length for wear, damage or incorrect seating. Confirm that the tooling is rated for the tonnage being applied, and that tall tooling is secured properly.
- 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 across the full 800 mm X-axis travel.
- 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.
