High-Speed MAXFORM Press Brake Cuts Cycle Times with 3,000 ipm Linear-Motor-Drive Backgage - An Industry First


Breakthrough 6-axis linear-motor-drive backgage complements advanced hydraulics and high-speed ram in "speed machine" processing for high throughput manufacturing operations

January 2007 - Press brake metal forming hits passing gear with industry's first linear-motor-drive backgage, available as an option on Cincinnati Incorporated's new high-speed MAXFORM hydraulic press brakes. The six-axis backgage uses linear motor drive to deliver re-positioning speeds of 3000 ipm in X (in/out) and Z (left/right) axes. The high-speed positioning eliminate resets waiting time for fastest sequential bending of complex parts - more strokes per hour and parts per shift. The 6-axis backgage uses ballscrew drive in R (up-down) axis where changes are infrequent. The breakthrough backgage complements the MAXFORM's speed machine capabilities. Advanced hydraulics and control technologies deliver up to 700 ipm ram speeds with 3 Sigma (±0.0002") repeatability for outstanding consistency in bending complex parts without deviation, drift or error stacking.

Especially suited to high-volume manufacturing operations, the high-speed MAXFORM package eliminates the press brake as a bottleneck to reducing work-in-process for many manufacturers. MAXFORMs are available in 90 to 350 ton models and lengths to 14 ft.

Engineered and built by Cincinnati, the backgage's linear motors are adapted from the company's drive systems proven for more than 10 years on industry's first linear-motor-drive laser cutting systems. Engineered for years of reliable service and positioning precision, the linear motors reduce noise, wear and maintenance downtime. No mechanical load is exerted on the drive from operators pushing material against gage fingers over years of use.

"Smart" graphic controls guide operators through each step of the bend sequence with 3D part views. Graphic displays and simulation software allow fast programming, fast setup and fast cycle speeds. "See and do-right" 3D graphics and automatic processing intelligence compensate for varied operator experience levels.

The MAXFORM comes standard with bolt-on CINCINNATI Quick Change ram nose designed for hardened, sectionalized American tooling. It maximizes ram protection by doubling load capacity from 15 to 30 tons per square inch. The versatile press brake offers as bolt-on options a Euro-style Ram Nose for European punch holders, and various hydraulic clamping systems.

Precision sectionalized tooling enables fast setup without aligning dies, while a comprehensive range of CNC programmable gages saves downtime by eliminating manual adjustment of gage fingers. A low-profile, 5-axis backgage comes standard, while the MAXFORM can be optionally ordered with the linear-motor-drive 6-axis backgage, a CNC Plate Backgage, or CNC frontgage. All power gages are laser-compensated at the factory for positioning precision.

Cincinnati's industrial PC-based touchscreen control and Windows® software eliminate two-thirds of the programming steps compared to conventional CNC controls. A Bend Simulation Module, standard on the MAXFORM, allows programs to be quickly created offline or at the machine and proved out step-by-step in realistic 3D views to avoid trial bending. Smart controls automatically calculate and apply adjustments for ram reversal position, bottom bending tonnage, gage allowances, and material springback.

The MAXFORM features the traditional built-to-last construction that earns CINCINNATI machines the industry's highest resale value. A rigid, heavyweight platform features interlocked frame members that eliminate weld joint failures. Hardened linear guides maintain ram accuracy, while clevis-mounted cylinders and hardened piston rods reduce wear, leaks and maintenance. Cincinnati backs the MAXFORM with industry-best five-year parts and one-year labor warranties.
