How Do I Choose the Right Press Brake Tonnage?

Press brake tonnage depends on material type, thickness, bend length, and V-die opening. For example, bending 6 mm mild steel with an 8T V-die typically requires around 50–60 tons per meter.

NC vs CNC Press Brake: Which Machine Is Better?

NC press brakes are suitable for simple and repetitive bending jobs with manual adjustments, while CNC press brakes are designed for complex multi-step bending with higher precision, automatic angle calculation, and faster setup times.

Q: What Is the Difference Between Servo-Electric and Hydraulic Press Brakes?

Servo-electric press brakes provide higher energy efficiency, lower maintenance, and faster cycle times for thin sheet applications. Hydraulic press brakes are better suited for heavy-duty bending and high-tonnage industrial production.

Q: What Are the Safety Rules for Operating a Hydraulic Press Brake?

Safe hydraulic press brake operation includes performing stroke adjustment tests, selecting the correct V-die opening, verifying backgauge alignment, avoiding tonnage overload, using safety guards, and releasing the foot pedal when not in use.

How It works

Understanding the Hydraulic System and Working Principle

A CNC press brake bends sheet metal by applying controlled hydraulic force through matched punch and die tooling.The CNC system synchronizes ram movement, backgauge positioning, and bending pressure,and tooling precision to achieve accurate sheet metal bending results.

Main Components

♦ Hydraulic system

♦ Ram and frame

♦ CNC backgauge

♦ Press brake tooling

♦ Foot pedal control

Key Performance Factors

♦ Bending tonnage

♦ Tooling precision

♦ Material springback

♦ Hydraulic synchronization

Why Correct Tonnage Matters

T=V1.42×S2×L
Incorrect tonnage selection for the metal press brakes may result in poor bend accuracy, tooling damage, or machine overload.

CNC & Servo Electric Press Brake Technology

Modern CNC press brake systems improve bending efficiency through automated programming, multi-axis synchronization, and precision backgauge control.

Compared with conventional hydraulic systems, servo electric press brakes provide:

♦ higher positioning accuracy

♦ faster cycle times

♦ lower energy consumption

♦ reduced maintenance requirements

Common Applications

♦ stainless steel fabrication

♦ electrical enclosures

♦ elevator panels

♦ precision sheet metal parts
