Dual Cylinder Press Brake Calculator

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.

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.

ADR and ADS hydraulic presses brakes are both fast and accurate. These press brakes can match any machine, with accuracy figures of +-.004 and repeatability. Like all JMT press brakes, the concept of large strokes with high openings and deep throats are present in these machines. This allows operators to make parts that have larger flanges and makes it much easier to remove them. A press that is faster, easier to set up, has a better operator interface, and moves at a breakneck pace will result in more parts in the bin at the end of each shift, with higher overall quality.

It is said that the "little guys" sometimes punch higher than their weight classes. Our small, 4-foot press brake is an example of this. The compact bender includes a CNC-controlled X-axis back gauge, tangs capable of accepting euro or american tooling, an LED rear working light and two front sheet supports that slide with a linear rail. There is also a dual palm/foot station equipped with a selector switch. This small, powerful and precise press brake packs a punch.

A press brake is a machine tool used for bending metal parts and sheets up to 20 mm thick. It is composed of a V-shaped or U-shaped die (depending on the desired bending shape) and a punch. The material to be bent is placed on the die and pressed by the punch which then bends the sheet to the selected degree.

Press brakes are a necessity to almost any metal fabrication shop. Unfortunately, despite being one of the most important and desired pieces of machinery in a shop, they’re still misunderstood—even by professionals. To help you better understand press brakes, we put together this short, layman’s-level guide.
