The CNC electro-hydraulic press brake—fully known as the CNC electro-hydraulic synchronized press brake and often referred to in the industry simply as an “electro-hydraulic press brake”—is a type of press brake that stands as a mainstream piece of equipment for high-precision sheet metal processing.
It offers the following advantages:
- It eliminates the need for a mechanical torsion bar, utilizing instead an electro-hydraulic closed-loop synchronization system; this limits the synchronization error between the left and right sides of the ram to ≤0.01mm, ensuring consistent bending angles across the entire length of long workpieces.
- The worktable features a built-in hydraulic crowning cylinder that automatically compensates for table deformation when bending thick or long materials, ensuring uniform bending angles along the entire workpiece.
- It supports multi-axis control, enabling continuous multi-angle bending and the automatic calculation of unfolded dimensions.
As a high-precision sheet metal machine, the CNC electro-hydraulic press brake is widely used across various industries. The primary sectors utilizing this type of press brake include:
- High/Low-Voltage Electrical Cabinet Industry: Primarily used for processing power distribution cabinets and boxes, PLC control cabinets, network server racks, PV inverter housings, switchgear enclosures, busbar trunking casings, electricity meter boxes, and energy storage battery enclosures.
- Stainless Steel Decoration / Kitchen & Bath Industry: Primarily used for processing stainless steel cabinets, countertops, elevator cars and doors, decorative elevator trim, hotel metal decorative panels, aluminum curtain wall panels, door and window frames, stainless steel sinks, commercial kitchenware, trash cans, and metal display cabinets.
- New Energy Industry:Primarily used for processing PV mounting brackets and frames, energy storage equipment housings, charging station casings, battery pack enclosures, sheet metal for new energy vehicle battery packs, and sheet metal components for wind power equipment.
- Automotive & Rail Transit Industry: Primarily used for processing bus side panels, coach luggage compartment panels, truck cargo bed liners, automotive chassis sheet metal, door reinforcements, lightweight aluminum alloy body parts, subway interior panels, truck light poles, and crash beams.
- Medical Device Industry: Primarily used for processing medical bed frames, instrument housings, stainless steel instrument cabinets for operating rooms, protective covers for medical equipment, and stainless steel sterile workstations.
- Construction Industry:Primarily used for processing architectural aluminum panels, metal ceiling panels, prefabricated steel structural components, guardrails, sheet metal accessories for bridges, street light poles, cladding panels for steel-structure factories, and long-format decorative panels.
Recently, a long-standing client with extensive experience in the crane industry approached us. They needed to process low-alloy, high-strength steel sheets measuring 10mm in thickness and 3000mm in length. Their requirements included deflection compensation capabilities, an interface for robotic synchronization, and a Delem CNC system. Our engineers promptly recommended the WE67K-350T/3200 CNC electro-hydraulic press brake. While consulting with us, the client also inquired with other suppliers who had recommended a 300T machine. Although a 300T machine could technically handle the material—09G2C low-alloy, high-strength steel with a yield strength of approximately 345 MPa—our engineers strongly recommended the 350T model based on professional expertise and practical experience (while still providing a quote for the 300T option). Ultimately, following an internal technical review, the client selected the WE67K-350T/3200 CNC electro-hydraulic press brake.
