Cincinnati repair in Illinois
Cincinnati Incorporated, based in Harrison, Ohio, has built press brakes and shears for more than a century, and its machines are everywhere in Midwest fabrication shops. In Illinois, you’ll find older Cincinnati mechanical press brakes still bending parts alongside hydraulic CB, Autoform, Maxforma and Proform brakes, Cincinnati shears of many sizes, and Cincinnati lasers in some shops.
Many of those machines are decades old and still productive, because Cincinnati built them heavy and simple. LocalSpindle techs work on old and new Cincinnati machines, including the hydraulics, mechanics, controls and backgauges.
Mechanical press brakes use a flywheel, clutch and brake to drive the ram. They’re simple and rugged, but their clutches and brakes wear, their air systems leak, and their controls and safety systems may be outdated. Clutch and brake problems are safety problems, and we treat them that way.
We repair clutch and brake systems, air valves, controls, backgauges and safety devices, and we can help you decide whether upgrading the control and safety system makes sense for a mechanically good older brake.
Cincinnati hydraulic press brakes are common in fab shops. Their problems include losing tonnage, slow or inconsistent ram motion, angle inconsistency, hydraulic leaks, valve problems, pump wear and backgauge issues. We check hydraulic pressures and valve operation, ram parallelism, crowning and backgauge calibration, and we repair or replace the components that are failing.
Cincinnati shears have common problems with blade gap and condition, hold-downs, backgauges, hydraulic systems on hydraulic shears and clutch and brake systems on mechanical shears. Poor cut quality, bowed parts and inconsistent sizes usually come from blade gap, worn blades or backgauge problems. We fix them and check safety devices.
Generations of brakes
An old Cincinnati mechanical press brake and a new Autoform are different machines. The old ones are about clutches, brakes, flywheels and mechanical adjustments. The newer hydraulic machines are about valves, seals, pressure and controls. We work on both.
Shears have their own list: blade gap, hold-downs, the backgauge and the hydraulics. A shear that starts leaving burrs or bowing parts usually needs blade attention.
Common calls
| Machine | Common calls |
|---|---|
| Hydraulic press brakes | Valves, seals, pressure, ram parallelism, crowning |
| Mechanical press brakes | Clutch and brake, flywheel, stroke adjustment, safety |
| Backgauges | Calibration, axes, retrofits |
| Shears | Blade gap, hold-downs, hydraulics, backgauge |
| CL lasers | Cut quality, heads, motion, chillers |

Mechanical brakes
Mechanical press brakes store energy in a flywheel and use a clutch and brake to make each stroke. When the clutch slips or the brake wears, the ram can stop in the wrong place or drift. That’s a safety issue, not just a quality issue.
We inspect clutch and brake wear, adjust them, check the stroke control, and check the guarding and light curtains. If an old mechanical brake needs safety upgrades, we’ll tell you what’s involved.
Hydraulic Cincinnati brakes are a different job: valves, seals, pumps and pressure.
Shear problems
| Symptom | Usual cause |
|---|---|
| Burrs on sheared edges | Blade gap wrong or blades dull |
| Bowed or twisted parts | Rake angle, hold-downs, or blade condition |
| Hold-downs don’t grip | Hydraulics or worn pads |
| Backgauge inaccurate | Calibration or mechanical wear |
Example service call
A structural fab shop in Joliet saw a Cincinnati hydraulic brake struggle to complete bends it used to make easily.
The result. Full tonnage restored.
