The V-die opening sets the main conditions of an air bend: natural inside radius, forming force, flange support, springback, surface marking, and tooling load. For standard 90° air bending in mild steel, use the following calculation as the first die-selection step: V-Die Opening = Actual Material Thickness × 8 The Rule of 8 provides a […]

A press brake spare parts plan helps reduce disruption when a component fails. It identifies items that may affect bending production, keeps essential machine information ready for technical review, and supports faster replacement decisions. For a new CNC press brake project, spare-parts planning should begin during specification, alongside machine capacity, control configuration, tooling, automation, and production

Choosing between press brake bending and metal stamping depends on part geometry, expected demand, design stability, and total manufacturing cost. Press brake bending is often the more practical option for prototypes, product variants, and low-to-medium production runs. Stamping can become more economical when the design is stable, demand is predictable, and dedicated tooling costs can

Press brake forming and roll forming can both produce accurate metal components, but they suit different production models. Press brakes are suited to flexible bending when parts, dimensions, or order quantities change. Roll forming is typically used for repeatable, long coil-fed profiles. The better choice depends on profile geometry, projected demand, part length, tooling investment, secondary

An OEM or ODM press brake program is more than adding a logo to a machine. It requires the right base platform, application-driven configuration, consistent branding, clear acceptance criteria, and dependable support after delivery. CNHAWE works with equipment brands, distributors, and integrators to turn press brake requirements into product ranges that can be sold, serviced,

Press brake terminology affects far more than communication. The right terms help buyers compare machine quotations, engineers prepare workable drawings, and operators set up bends with fewer avoidable errors. This glossary explains 50 practical terms used in press brake selection, tooling, programming, bending and inspection. Use it when reviewing a part drawing, preparing an RFQ,

Quick answer: choose mechanical quick clamping when the tooling is light, easy to handle, and limited in length or segment count; choose hydraulic quick clamping for high-mix production, longer tool layouts, or more demanding changeovers; consider pneumatic clamping when air supply, tooling compatibility, and the locking design align. In every case, verify the tool interface,

A custom CNC press brake starts with the parts you need to produce. Tonnage and bending length matter, but they do not define the whole solution. Part geometry, material range, tooling, output, handling, and factory conditions determine how the machine should be configured. CNHAWE uses these inputs to develop press brake solutions that support the way

A CNC press brake controller should be compared as part of the complete machine quotation, not by its feature list alone. Two machines using the same controller platform can still differ in programming capability, axis configuration, crowning arrangement, software scope, and commissioning. The key is to confirm that the quoted configuration matches the parts, workflow,

High-mix, low-volume sheet metal production is governed by the time between jobs. When materials, part geometries, bend sequences, and order quantities change frequently, the key measure is not single-bend speed. It is the time from the last approved part of one job to the first approved part of the next. Start With the Real Part

A CNC press brake makes sheet metal hems by forming a short return flange and then closing or flattening it with dedicated hemming tooling. The process is used to cover sharp edges, improve local stiffness, and create a clean finished edge on panels, enclosures, doors, covers, and stainless-steel equipment. Reliable hemming requires more than sufficient press

Quick answer: Yes, a CNC press brake can bend many perforated sheet metal parts. Because holes and slots reduce local rigidity and interrupt support from the tooling, perforated sheet can be more prone to distorted holes, waviness, surface marks, and angle variation than solid sheet. The result depends on the material, perforation layout, bend geometry, tooling,
