All-Electric Press Brakes for Precision Bending Without the Hydraulic Footprint
Electric press brakes have changed the game for fabrication shops focused on accuracy, repeatability, and sustainability. By replacing hydraulic cylinders and oil with AC servo motors and ball screws, an electric press brake machine produces consistent bends across long production runs while drawing significantly less energy than its hydraulic counterparts.
There’s no hydraulic oil to manage, no warm-up cycle to wait through, and no oil temperature drift to account for in tolerance-critical work.
MC Machinery, working with Mitsubishi (the originators of the world’s first electric press brake), offers the Diamond BB Series as its all-electric platform. The BB Series achieves the industry’s fastest cycle time in class at 2.1 seconds, with ram repeat accuracy of 1 micron and back gauge positioning accuracy of 4 microns.
Where Electric Press Brakes Fit Into Real Production EnvironmentsProduct Grid
From high-mix job shops to precision production environments, the BB Series handles a wide range of bending applications:
- Automotive and Aerospace: Precision sheet parts with tight tolerance requirements benefit from 1-micron ram repeatability and 4-micron back gauge accuracy. Automatic thickness compensation minimizes angular variation across hardened sheet stock.
- Structural Fabrication: Repeatable bending on smaller structural components is faster with the BB Series because cycle times are short and setups move quickly between jobs.
- High-Mix, Low-Volume Shops: For shops cycling through varied job mixes daily, fast setup time and a 22″ multi-touchscreen interface with 3D simulation keep the machine productive across constant changeovers.
- Sustainability-Focused Manufacturers: No hydraulic oil, lower electricity consumption, and quiet operation make the BB Series a strong fit for shops working toward carbon reduction or LEED-certified facility goals. Operators benefit too, as the machine produces less noise than hydraulic alternatives.
- Operators and Shop Owners of Varied Experience Levels: The intuitive Windows-based control, automatic thickness detection, and optional Videre operator support system reduce the learning curve for new operators while giving veteran operators the tools they expect.
The BB Series is MC Machinery’s all-electric press brake line, built on AC servo motor and ball screw technology that traces back to Mitsubishi’s pioneering work as the originator of the world’s first electric press brake. Every machine in our lineup ships with a 22″ multi-touchscreen CNC interface running Windows, 3D simulation capability, automatic thickness detection and compensation, Mitsubishi servo amplifiers and motors, European one-touch tool holders, and a standard 4-axis (BB40/60) or 5-axis (BB30) back gauge with 6″ X-axis maximum gauge distance.
Available models include:
- BB306: 28 metric ton press force, 630 mm bending length, configured for shops focused on smaller precision parts with a 5- or 6-axis back gauge.
- BB4013: 36 metric ton press force, 1,260 mm bending length, a mid-range configuration that expands bending capacity for shops working through varied job mixes.
- BB6013: 55 metric ton press force, 1,300 mm bending length, higher force at a similar bending length to the BB4013, suited to heavier sheet stock at fast cycle times.
- BB6020: 55 metric ton press force, 2,100 mm bending length, top of the lineup, pairing the higher press force with the longest bending length for larger parts at production volume.
Optional features across the lineup include 5- or 6-axis back-gauge upgrades, angle measurement, sheet followers and supports, DiamondBend offline programming software, automatic tool changers, and the Videre operator support system.
Why Manufacturers Choose the BB Series Electric Press Brake
The BB Series stands on a few clear differentiators:
- Industry-fastest cycle time at 2.1 seconds, achieved through high-speed ball screw drive and Mitsubishi servo motor technology.
- Precision built in from the start. 1-micron ram repeatability and 4-micron back gauge accuracy come standard, not as upgrades or options.
- Lower long-term operating costs. Electricity consumption stays lower than that of equivalent hydraulic machines, and the absence of hydraulic fluid eliminates oil changes, leaks, and disposal concerns.
- Onboard productivity tools. Automatic thickness detection and work-efficiency analysis reduce scrap and help keep operators working at peak production.
