This type of bend is used most frequently for sheet metalworking because it can be used with machines with reduced capacities. It is not as strong as bottom bending, which is more difficult.
Press brakes are machines that form lengths of sheet metal. These sheets are typically used in manufacturing, industrial applications, or as components for other devices. Most press brakes are rated by their capacity to press metal and their overall bending length; this is expressed in numbers (e.g., total PPI, or pounds of pressure per inch). They come in many forms and often are equipped with tooling and add-ons designed to create highly customized components. Press brakes fall into two main categories: mechanical and hydraulic. In the next sections, we’ll break down the difference and explain the prominent features of each style.
A press brake fitted with a Mitsubishi automatic tool changer (ATC) stands out in all kinds of ways.
Imagine Gigantically large and intelligent press brakes that can handle a wide range of metal materials and tonnages. Our mega mega press brakes are made with advanced engineered technology box construction frames that give our mega brakes the strongest brake machine body. Our large high-tonnage mega press brakes incorporate our box construction frame design. We have received approval from all of our customers. The high-tonnage press brake is designed to reduce the handling of large pieces of work before, during, and after bending and to respect the next step.
Tonnage is the force that the press brake applies to the material. It determines how much pressure can be applied to the punch during bending.
This method offers high levels of precision and angular accuracy. This method is ideal for sheet metal with a thickness of more than 2 mm.
Hydraulic Press Brake Machine IndiaNext, determine the specific characteristics that must be taken into consideration when calculating the bend. You will need to consider the following:
Add to that the incredible machine capabilities mentioned above, and you will be amazed at what we can do for you. If you are looking to upgrade your press brake or make an initial investment, we can help. We have the tools you need and are factory-trained Wilson and Wila tooling experts.
Our Servo Hydraulic Press Brakes can bend metal with up to 66% less power consumption at stand-by and 44% less energy use during the bending cycles. Our servo braking system is powered by AC Servo motors. These motors drive hydraulic oil on demand in conjunction with variable speed pumps. Our advanced technology ensures that our servo presses have a significantly lower price per part. We use only the most powerful electronic, electric and hydraulic power when it is needed. You won't find any quieter, less energy-intensive or more accurate press brake.
Searching for the perfect blend of serious bending power and cost-efficient operation that doesn’t sacrifice quality or output?
Warning: incorrect tonnage (too high or low) can damage your press brake or the part you are bending. To calculate the tonnage of your press brake, refer to the operating manual or a tonnage table.
Standard currently makes the largest selection of hydraulic press-brakes on the market. We have 20 models in our ADR 5 Axis CNC Hydraulic Press Brake Series. They are small, up to 4 feet in length, and large, up to 20 feet in bending length. 7 different tonnages are available, ranging from 66 tons to 440 tonnes. Our ADS series, a premium and more advanced model, is available in 32 models. They can bend metal lengths from 6' 8" to 26' 5". Our ADS series machines have 13 different tonnages and can bend up to 3,300 tons. The PBF series is also available for customers that require a standard press brake. Another side of the coin are the advanced AD Servo Brakes that feature a hybrid hydraulic configuration with ball screws for quiet operation and energy efficiency. Standard is bringing to market the FBS-series, which is short for flexible bending solutions press brakes. FBS series brakes have a high tonnage and can be customized to fit customer's exact requirements. The brakes can also run tandem or trio press brakes.
This options list could be almost endless, we will just list the major ones here, if you don’t see something you want, just ask us we probably have it.

Light curtain Sick C 4000 for combination machines. Additional axis up to 14. Extended travel back gauge to 39 inches with safety light curtain. Sheet follower with motorized height adjustment. Updated cnc controllers from Delem (DA69T) or Cybelec (10S,12S,15S, 3D with PC1200). Quick release clamping, hydraulic clamping, Wila or Wilson mechanical or hydraulic clamping, tooling options from the “who’s who” of press brake tooling. Bottom tool positioning systems, thickness measurement systems, offline software for V-Bend or Profile-W.
There are two methods that press brakes can bend steel. The first, or bottom bending, is when the ram presses metal to the bottom. Bottom bending can produce precise bends and is less dependent on the press brake. The problem is that each tool is designed for a specific type of bend. You will need to purchase a brand new tool for each angle. Air bending creates an air pocket between the die's bottom and the ram. This allows the operator flexibility in accommodating any spring back provided by the material. These types are only necessary to be replaced if the material is too thick. The drawback of air bending is its inability to accurately bend the material. This means that the ram will need to be changed accordingly.
With about 70 lbs, the average person can push on the brake pedal. You can apply the brake pedal with about 70 lbs. To stop a moving vehicle disc brakes require 800-1200 psi at their calipers. All parts of the system amplify the force you apply to the pedal.
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.
A hydraulic press crushed a worker to death in an industrial accident. Two workers were placing materials under hydraulic presses. An online video of the incident shows this. While the victim was fixing the materials, the worker controlling the machine turned the engine on.
Hydraulic brake failures are most common due to either loss of hydraulic pressure, or brake fade on steep hills.
Hydraulic presses can be used for forging and clinching, moulding blanking, punching as well as metal forming operations like deep drawing and blanking. Hydraulic presses can also be used for rubber pad forming and powder compacting.
