Industrial Punching, Bending & Shearing Workstations
CNC busbar processing equipment built for switchgear panel manufacturing, power grid infrastructure, and EV battery bus assembly. Monoblock cast-iron frames, factory pre-calibrated, deliver ±0.2mm precision. Integrated 3D nesting cuts copper waste by up to 15%.
Standard split-body CNC busbar machines require expensive on-site alignment, produce high copper waste, and carry steep operator training curves. Our busbar processing equipment is engineered to eliminate each one.
Traditional multi-frame CNC machines lose alignment during sea transit, requiring $3,000-$5,000 in on-site recalibration fees.
Monoblock Pre-Calibrated Shipping
Every DH CNC workstation ships on a single cast iron mono-block frame. Factory pre-calibrated and stress-tested for 72 hours. Zero drift after transit.
Manual layout and double-cut shearing generate 12-15% copper waste on T2 busbars, leaking thousands in raw material costs annually.
3D Nesting Software Saves 12.5% Copper
Our proprietary 3D nesting algorithm imports CAD files directly and optimizes hole layouts across standard 6m bars, reducing scrap to below 3%.
Complex G-code programming requires weeks of training per operator. Manual trigonometry errors lead to scrapped copper and downtime.
Drag-and-Drop CAD Interface
Touch HMI accepts direct STEP and DXF files. Pre-loaded templates for common punching patterns. New operators produce quality parts in under 4 hours.

From ductile iron casting to 72-hour stress testing — explore how every CNC busbar machine is built for decades of precision performance.
Open-frames are cast from heavy-duty ductile iron for excellent mechanical resistance and consistent alignment tolerances during hydraulic stress peaks.
Bending, punching, and guide tracks are milled on a single gantry bed. Monoblock integration locks in absolute geometry stability.
Each hydraulic valve block and servo pump undergoes 72 hours of uninterrupted stress calibration to verify absolute zero leak rates.
Workstations are vacuum sealed in moisture-proof barrier bags, boxed inside solid fumigated export crates for perfect rust protection.
Hydraulic engineering with globally-sourced components, grid-specific motor calibration, and remote diagnostics — why switchgear manufacturers worldwide choose DH CNC busbar processing equipment.
Unlike cheaper multi-function machines that share a single hydraulic pump, DH CNC workstations feature 3 independent high-pressure 31.5 MPa pumps paired with three individual Siemens electric motors. Each station (punching, shearing, bending) operates at 100% force and speed simultaneously with zero pressure drops.
All cylinders, guide columns, and bending tracks are milled on a single gantry bed. The heavy-duty ductile iron monoblock frame absorbs continuous hydraulic stress cycles, guaranteeing absolute geometry stability and zero warping or alignment drift over decades of operations.
Every workstation is built with globally recognized, top-tier components: Siemens Smart PLC touch interface, Yuken hydraulic proportional valves, HIWIN high-precision linear guide rails, and Schneider Electric hardware. This ensures local spare parts availability and immediate international serviceability.
Every machine ships with an active, secure remote diagnosis gateway. Our chief engineers can remotely access operation logs, troubleshoot hydraulic proportional valve alignment, inject custom CAD bending calibration parameters, or update firmware directly over the air.
