Product description
The GH-3260DS is a heavy-duty, long-bed CNC press brake from GHBM's DS Series. It has a working force of 320 tons and a maximum bending length of 6000 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 500 mm daylight opening, a 300 mm ram stroke and a 450 mm throat depth. The hydraulic system is driven by two 11 kW main servo motors, and the specified oil volume is 80 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.
Features
320-Ton Working Force
Maximum working force of 320 tons for heavy plate bending.
6000 mm Bending Length
6-metre maximum bending length, with 5180 mm between columns, for extra-long workpieces.
300 mm Ram Stroke
Long stroke for tall tooling and deep parts.
500 mm Daylight Opening
Room for taller tooling and deeper formed parts.
450 mm Throat Depth
Deep throat for wider flanges and larger panels.
Dual Main Servo Motors
Two 11 kW Techmation main servo motors (11 kW × 2) drive the hydraulic system.
Dual Oil Volume
Hydraulic oil volume specified as 80 L × 2.
Seven-Axis CNC Configuration
Y1, Y2, X, R, V, Z1 and Z2 axes for multi-axis control.
GHBM-940T CNC Controller
Paired with a 21.5-inch Techmation display screen.
Closed-Loop Position Feedback
Uses an OPKON closed-loop position sensor.
Fast, Repeatable Backgauge
X-axis: 600 mm stroke, up to 350 mm/s. R-axis: 150 mm stroke, up to 150 mm/s. Repeatable positioning accuracy of ≤0.05 mm on both axes.
Quick-Release Tooling
GHBM single-side quick-release clamp.
Dust-Proof Compensation Worktable
Compensation worktable with dust protection, important for consistent angles over a 6 m bend.
Hydraulic Sealing and Fittings
SKF/NOK cylinder seal kit and EATON compression fittings.

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 6 m length of the worktable, tooling, clamps and backgauge area.
- Hydraulic oil checks: Check the oil level and condition in both 80 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, alignment or incorrect seating. Confirm that the tooling is rated for the tonnage being applied.
- Compensation checks: Periodically verify bend angle consistency across the full length, and recalibrate worktable compensation if needed.
- 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.
