CNC Corner Notching Machines for Sheet Metal

A notching machine is an industrial machine used to cut notches—corners, edges, or irregular shapes—in sheet metal and other materials. It works by using a punch and die set to remove material from the workpiece edge, creating precise cutouts. Notching is commonly used before bending or forming to create clean corners, allow overlapping joints, or prepare edges for welding. Manual, semi-automatic, and CNC notching machines are available.

Our notching machines can process mild steel, stainless steel, aluminum, galvanized steel, copper, brass, and non-metals such as acrylic and PVC. Processing capacity depends on material type, thickness, and notch size. Please refer to our specifications for specific material capabilities and recommended tonnage.

Standard notch shapes include 90° square notches, 45° and 60° angle notches, V-notches, round corner notches, and custom profiles. Tooling can be changed to achieve different notch dimensions and angles. Our machines support quick-change tool systems for efficient switching between jobs. Custom punch and die sets can be provided for special applications.

Yes. Our CNC notching machines can produce multiple notches along edges through programmed X-Y positioning. They support CAD/CAM file formats for accurate reproduction of designs. Optional features include automatic sheet clamping, back gauge positioning, and multi-tool heads for switching between notch shapes without manual changeover.

Standard models typically ship within 4-8 weeks. Custom configurations or special tooling may require longer lead times. All our notching machines come with a comprehensive warranty covering major components including the punch head and drive system. Extended warranty options are available.

We offer manual notching machines, hydraulic notching machines, and CNC notching machines. Manual models suit low-volume production and simple notch shapes; hydraulic models provide higher tonnage for thicker materials; CNC models enable programmable positioning for complex patterns and high repeatability. We also provide single-station and multi-station configurations for different production requirements.

Our notching machines typically handle sheet thickness from 0.5mm to 6mm for mild steel, with notch depths and widths adjustable based on tooling. Maximum workpiece size varies by model—typically from 1000×2000mm up to 2500×5000mm or larger. Tonnage ranges from 16 tons to 63 tons depending on model. Contact us for specifications tailored to your production needs.

Notching removes material from the edge of a workpiece to create corners, cutouts, or profiles—typically used for preparing sheet edges before bending. Punching creates holes or shapes anywhere on the sheet, often in the interior. Notching machines are optimized for edge work with dedicated tooling; punching machines use a turret for multiple hole patterns across the sheet.

Regular maintenance includes inspection and sharpening of punches and dies, lubrication of guide rails and ball screws, hydraulic oil changes (for hydraulic models), and verification of safety systems. We provide detailed maintenance schedules and operator training. Annual professional inspections are recommended to ensure optimal performance and tool life.

Yes. We offer professional installation and commissioning, operator training on safe operation and programming, and comprehensive after-sales support including spare parts (punches, dies, seals, etc.) and technical assistance. Our global service network ensures prompt response when you need us.
