Frequently Asked Questions About Shearing, Notching & Punching Machines
Base the choice on material type, max thickness and sheet length. Allow a sensible margin above your typical thickness and confirm blade length, backgauge travel and hold-down style for your parts.
Swing-beam machines are robust and economical for general shearing. Vertical-action machines keep a near-straight blade path for improved accuracy, especially on thicker plate. Variable-rake allows tuning of rake angle and blade gap for best edge quality across different materials.
Correct blade gap and rake reduce burr and distortion. Powered backgauges improve repeatability and throughput. For long parts consider supports, squaring arms and pneumatic sheet supports.
Typically punch, flat bar shear, round/square bar shear, angle shear and notching. Tonnage, throat depth and tooling options vary by model.
Fixed-angle or variable-angle notchers are available. Check throat depth, max thickness and whether scrap evacuation and guides suit your parts.
Machines are CE-compliant with appropriate guards and interlocks. Confirm electrical supply (kVA), air requirements where applicable, and extraction if needed.
