• 8 Press Brake Machine Mistakes and How to Avoid Them

  Feb 13, 2026

  Something metal fabricators like to avoid is an upset ram. No, that’s not a distraught male sheep wandering in from the farm next door, it’s a press brake machine problem. The ram is an integral part of the press brake, and to say it’s upset means it’s bent. It’s bad news when parts of your machinery get bent because that makes it hard to form quality parts. Machines don’t have to be new to work well, but they do have to be cared for. Here’s a look at the importance of press brake maintenance. Putting in straight bends Sheet metal fabrications almost always go through the press brake. This is where we change it from sheet to a three dimensional shape. Those bends must be straight otherwise the final assembly won’t go...

• How to avoid deviation in bending angle and size

  Feb 06, 2026

  For the bending process, the quality of the bending forming mainly depends on two important parameters: the angle and size of the bending. When bending, in order to ensure the forming size and angle of the bending, attention should be paid to the following aspects. (1) The misalignment of the upper and lower molds can lead to errors in bending dimensions. Before bending, it is necessary to adjust the alignment of the upper and lower mold tools. (2) After the left and right positions of the rear block are moved, the relative position between the sheet metal and the lower mold may change, which may affect the bending size. Before bending, the distance between the rear block positions needs to be re measured. (3) Insufficient parallelism between the workpiece and the lower mold can cause bend...

• Bending Basics: 6 steps to successful die selection for press brakes

  Nov 24, 2025

  What inside bend radius you can achieve hinges on tonnage requirements and available die-opening widths     Figure 1 To get the most out of your press brake tooling, the tangent of the bend, where the radius starts, ideally should be halfway down the die face. In this situation, half the die face is equal to the outside setback (OSSB), the distance from the outside mold line (planes that run parallel to the workpiece) to the tangent point of the bend.   Question: Our fabrication department is documenting standard processes to select the correct punch and die combination to produce the desired results when air bending. We want to achieve a 90-degree bend for a 0.0751-in.-thick piece of 304 stainless steel with an inside bend radius that’s also 0.075...

• Press Brake Basics for New Operators

  Nov 09, 2025

  Press brakes are advanced forms of fabrication technology used for bending sheet or plate material, most commonly sheet metal. Successfully using one requires a detailed understanding of how the machine functions and the role of the person operating it.   If you’re new to working with press brakes, there are some important things to keep in mind:   Types of Press Brake The two most common types of press brake are hydraulic and electric:   Hydraulic Press Brakes: These are easier to use and come with a lower price tag. They are ideal for working with large, inexpensive materials that do not require high-precision bends. Typical pressure forces range from 40 to 600, and a hydraulic press brake will likely be your only option if you require a brake larger than 300 to...

• What material requirements should CNC press brake tooling meet?

  Oct 23, 2025

  To ensure the durability of CNC press brake tooling, the selection of materials is extremely stringent. Only materials that meet the following requirements are considered high-quality.   1. Wear resistance   This is a basic and crucial material property. During the production process, intense friction occurs between the mold surface and the workpiece. If the material is not wear-resistant, the CNC press brake tools will easily become damaged and fail.   2. Toughness   The working environment is relatively harsh, and the mold must withstand tremendous impact forces. Only strong and tough materials can withstand such impact without breaking.   3. High-temperature resistance   CNC bending tool operate in high-temperature environments, which can reduce their hardn...

• A press brake is a machine capable of bending metal sheets

  Oct 14, 2025

  A press brake is a machine capable of bending thin sheets. Its structure primarily consists of a support, a worktable, and a clamping plate. The worktable is mounted on the support and consists of a base and a pressure plate. The base is hinged to the clamping plate. The base consists of a housing, a coil, and a cover. The coil is located in a recess in the housing, and the top of the recess is covered by the cover. During operation, a wire energizes the coil, generating an attractive force on the pressure plate, thereby clamping the sheet between the pressure plate and the base. The electromagnetic clamping mechanism allows the pressure plate to be shaped to various workpiece requirements and can process workpieces with side walls, making operation very simple.   CNC press brakes and...

• Maintenance and upkeep of the press brake

  Oct 11, 2025

  Before performing machine maintenance or cleaning, the upper punch should be aligned with the lower dies and the machine should be lowered and turned off until the work is completed. If startup or other operations are required, the mode should be selected as manual and safety should be ensured. The maintenance content is as follows:   1. Hydraulic oil circuit 1) Check the oil level in the fuel tank every week, and also check it after hydraulic system maintenance. If the oil level is below the oil window, add hydraulic oil; 2) The hydraulic oil used in this machine is ISO HM46 or MOBIL DTE25; 3) The new machine should have its oil changed after 2000 hours of operation, and every 4000-6000 hours of operation thereafter.

• How to Use a Press Brake

  Oct 05, 2025

  1. First, turn on the power, turn on the key switch on the control panel, and then press the oil pump to start. 2. Stroke Adjustment: When using a press brake, always pay attention to stroke adjustment and perform a test run before bending. When the upper die of the press brake reaches its lowest point, ensure there is a gap equal to the plate thickness. Failure to do so will damage the die and the machine. Stroke adjustment is available through both electric quick adjustment and manual fine adjustment. 3. Select the bending notch. Generally, choose a notch width that is eight times the plate thickness. For example, if you are bending a 4mm plate, you should choose a notch width of approximately 32mm. 4. Adjusting the back gauge is generally available through electric quick adjustment and...
