T-SLOT SUPPORT ARMS
All brakes come standard with (2) 24" basic work supports. Optional T-slot support arms have precision t-slot bars added to set optional gravity stops. Available in 24”, 36” or 48” and with imbedded scales.

QUICK RELEASE LINEAR WORK SUPPORTS
Quick-change, quick-disconnect style support arms with heavy duty, smooth transition roller guides for easy arm movement. Multiple adjustment points on arms for super precision placement.

CNC SHEET ASSISTS
When operator safety and precision part handling are a priority, our CNC sheet assists are the solution. CNC controlled for precision part following and available for any level of production.

TOOLING
Available on all 3 models of press brakes are single V, Four Way Conventional tooling plus Wilson/Wila Precision Ground, Segmented tooling. All tooling requirements available.

MANUAL CROWNING
For the most precision requirements, manual crowning allows the operator to set the desired deflection.

RAM AND BED CLAMPING SYSTEMS
Quick-change, powered clamping systems for upper and lower tooling providing you the quickest set up times possible. Perfect for American or New Standard style of tooling. Lower clamping available with or without crowning.

AMERICAN AND NEW STANDARD PRECISION TOOLING
Precision ground to +,- .0004” and hardened at wear points, segmented tooling is the answer for quality and fastest set up times.

CNC CROWNING
For the most precision requirements, CNC crowning allows the operator to program the desired deflection for each job reducing set up time.

RAM AND BED CLAMPING SYSTEMS
Quick-change, powered clamping systems for upper and lower tooling providing you the quickest set up times possible. Perfect for American or New Standard style of tooling. Lower clamping available with or without crowning.

AMERICAN AND NEW STANDARD PRECISION TOOLING
Precision ground to +,- .0004” and hardened at wear points, Wila segmented tooling is the answer for quality and fastest set up times.

TRADITIONAL PRESS BRAKE AND STRAIGHT SIDE PRESS CAPABILITY
With our hydra-mechanical drive system providing full tonnage the length of the bed, the model AB press brakes have the ability to be used with traditional press brake tooling and optionally can have either permanent or removable flanges for press die applications. Removable flanges on the bed and/or ram will allow you to utilize both conventional press brake tooling as well as press die applications as needed. Permanent bed and ram flanges will allow a wide array of press die applications for substantially less cost of a traditional straight side press.

OPERATIONAL PREFERENCE CONTROLS - AUTO RETURN OF RAM
Normal operation of ram requires operator to release footswitch to allow ram to return to upper limit. This option makes the ram return automatically even if footswitch is still depressed.

DECOMPRESSION SYSTEM
REQUIRED FOR BOTTOMING APPLICATIONS—allows oil pressure to bleed off to reduce shock to hydraulic system.

EXTRA STROKE/EXTRA OPEN HEIGHT/DEEPER THROATS/HORN EXTENSIONS
All our machines can be tailor made to your exact needs

AUTOMATIC LUBRICATION SYSTEM (air power required)
Automatically pumps EP-1 grease through lubrication system via a timed system. Also includes flow adjustable injectors. Includes auto-shutoff with warning light when reservoir is empty.

MODEL AB PRESS BRAKE GAUGING OPTIONS
The AB Conventional press brake is perfect for companies who want the choice of either simplified, basic controls or state of the art 2D/3D CNC sophistication. The model AB is essential for any level of production from single shift facilities up to the largest multi-shift corporations in the world.
Regardless of your needs, if you want a dependable machine that lasts for decades but also want to choose your level of control complexity, then the model AB Conventional is your machine.
