This method provides a high level of angular precision.It is suitable for sheet metal over 2 mm thick.
The motor inside a mechanical press brake operates via a motor. This motor spins an enormous flywheel at high speeds. The machine operator controls the flywheel via a clutch. A clutch then sets the other parts in motion and bends the metal. The mechanical press brake, with its electronic controls, is much simpler and makes maintenance and operation simple. A mechanical press brake can handle tonnages that are two to three times larger than their intrinsic rating due to its design. The downside to using mechanical press brakes, however, is that the machine's ram must complete its full cycle before it can be reversed. The operator can make mistakes, which could lead to safety concerns. A potential danger is that the press brake may become locked if it travels too far.
If timelines and deadlines are pressing in on your production line, a fully automated press brake solution can go a long way toward relieving some pressure—on both your bottom line and your peace of mind. But how?
Our popular precision performance to value-oriented CNC hydraulic press brakes have exceptionally large strokes, daylights, and throat depths to allow cost effective production of simple to complex shapes that require large dimensions for ease of handling and removal. An easy to use cnc control reduces the required operator skill level. Precision accuracy tolerances of .ooo4 and unmatched repeat-ability-you simply won't find a higher quality press brake for the price!
It offers raw power, heavy-duty performance in bending, and improved technology, all in a cost-effective package.
It’s been said that "the little guys sometimes punch well above their weight class." Such is the case with our small 4 foot press brake. This compact bender comes standard with a CNC controlled X axis back gauge, tangs that accept euro or american style tooling, LED rear working light, two sliding front sheet supports with a linear rail, and a dual palm/foot station with a selector switch. You for sure are going to want to check out this new powerful, fast and accurate small press brake that packs a bend "punch" like no other.

Mechanical press brakes work by a motor contained within the device. This motor spins the large flywheel at high speeds. The machine operator controls this flywheel using a clutch. After that, the rest of the components are in motion to bend the steel. The mechanical presses brake is easier to operate and maintain, particularly in regards to the electronics. Due to their nature, the mechanical press brakes are able to handle tons two to three-times higher than their inherent rating. The main disadvantage to mechanical press brakes is the fact that the ram within the machine must complete a full circle when it's engaged. It cannot be reversed. This presents safety concerns in the event that the operator makes mistakes and places restrictions on the machine. There is a possibility that the brakes could be locked if the ram travels too fast.
The tonnage of a Hydraulic Press Brake, also known as the Press Capacity, is what determines how large a work-piece can be processed by the Press Brake. It is also the unit of force measurement that a press brake can deliver. This is what bends work pieces into desired/specific degrees. Our Press Brakes can handle tonnages from 30 to 3000 tons, while the bed lengths start at 4 feet and go up to nearly 30 feet.
Machines that press brake sheet metal are used to form long sheets. These sheets are commonly used in manufacturing, for industrial applications, or to make components for other devices. Most press brakes have a rating based on their pressability and their bending length. This information is expressed as numbers (e.g., total pressure per inch, or pounds of pressurized material per inch). They are available in many sizes and can often be equipped with additional tools and add-ons to make custom components. The two main types of presses brakes that you will find are hydraulic and mechanical. In the following sections, we will explain the main features and distinguish between the two types.
Bottom bending involves bending the metal sheet using a punch with a force that is 3 to 5 times stronger than air bending. This decreases or prevents the springback effect commonly associated with airbending. This begins with air bending and continues at the bottom with cold forging.
As part of our Perfect Machine Process, every Standard hydraulic press brake is rigorously inspected in our Rockford, Illinois, facility so that it’s ready for seamless installation in your shop.
Air bending uses the punch's end and the V's edges to allow sheet metal to bent. This type bending also has a springback effect. Because the bending forces are weaker, the sheet of metal will bounce backwards much like an elastic once the punch has been removed.
The press brake is, in reality, one of the most difficult machines to master in the trade. Every sheet metal operation needs to bend.
Experts estimate that hydraulic brakes require twice as much electrical energy to operate an electric press brake. The hydraulic motors, pumps and oil that hydraulic press brakes use to operate the machine keep it running, even when it's not in use.
The CNC Press Brake is fast to set up and has a repeatability of +/–0.0004 inches. This will allow you to reduce the time it takes to make parts.
Crowning is the method by which press brakes correct for deflections in both the upper beam or lower bed when pressure applies. There are different methods, depending on the model and make of the press brake.
You shouldn't use the clutch to turn corners. The transmission mechanism is freed by pressing the clutch, which can affect the vehicle's stability. If your vehicle is in an imbalanced position while you turn, it can lose traction. Depending on the speed, the vehicle may tip over.
