What is the difference between a CNC press brake and an NC press brake?

A CNC press brake offers higher axis control, graphical programming, better repeatability and easier setup for mixed jobs. An NC torsion-synchro press brake is simpler and lower cost for standard bending work.

Press Brake Machines: CNC, Hydraulic & Tandem Bending Guide

Q: How do I choose the right press brake tonnage?

Press brake tonnage depends on material type, thickness, bend length, tensile strength and V-die opening. Buyers should calculate tonnage from real part drawings and keep enough reserve capacity for production variation.

Press Brake Guide

What is a press brake and how should buyers compare machines?

A press brake is used to bend sheet metal into flanges, channels, brackets, cabinets, panels and custom formed parts. The right machine depends on material thickness, bend length, required angle accuracy, tooling, controller level, back gauge axes, crowning and production volume.

Buyers may also search for a bending machine, sheet metal bending machine, CNC bending machine or hydraulic bending machine. In Rucheng's current sheet metal product range, these terms usually refer to press brake machines for plate and sheet bending, not rebar, pipe or wire bending equipment. Use the sheet metal bending machine guide to confirm the machine category before comparing press brake models.

FAQ

Press brake machine questions

What is a press brake machine?

A press brake machine bends sheet metal by pressing the workpiece between an upper punch and a lower die. It is commonly used for cabinets, brackets, enclosures, panels, channels and many custom sheet metal parts.

How do I choose the right press brake tonnage?

Tonnage depends on material type, thickness, bend length, tensile strength and V-die opening. Share your drawings and thickness range so the machine can be sized with enough working margin.

Should I buy a CNC press brake or an NC press brake?

Choose a CNC press brake for high-mix production, tighter tolerances, complex parts and frequent program changes. An NC torsion-synchro press brake can be a practical choice for simpler parts, standard batches and lower budgets.

How much does a CNC press brake machine cost?

CNC press brake price depends on tonnage, working length, controller, back gauge axes, crowning system, tooling, safety devices and automation. Small machines are lower cost, while tandem, robotic and heavy-duty configurations require custom quotations from drawings and production requirements.

Is Rucheng a China press brake manufacturer?

Yes. Rucheng manufactures and supplies CNC hydraulic press brakes, NC press brakes, tandem press brakes, heavy-duty press brakes, robotic bending cells, tooling and related sheet metal fabrication equipment from China for export buyers.

Can Rucheng customize press brake specifications?

Yes. Rucheng can recommend and configure tonnage, working length, controller, back gauge axes, crowning, tooling, safety system and automation options according to your production requirements.

What press brake size do I need for 3 to 6 mm sheet metal?

For common mild steel work, 3 mm sheet over 2 to 3 meters often fits the 100 ton class, while 4 to 6 mm sheet usually needs 160 to 250 tons depending on bend length, V-die opening and material grade. Calculate from the actual drawing and keep 20 to 30 percent reserve.

What information should I send for a press brake quote?

Send material grade, thickness range, maximum bend length, required inside radius, minimum flange length, bend angles, annual output, accuracy requirement, workshop voltage and any preferred controller, back gauge, crowning or tooling requirements.
