How to Select Press Brake Controller?

I. Introduction

1. NC VS CNC Control System


In the world of metal fabrication, choosing the right press brake machine controller is paramount for precision and efficiency. The numerical control system of the press brake is a system that controls the machine’s procedures through a series of programming.

The control system of the press brake is divided into NC and CNC controllers. Both CNC and NC controller are used to ensure the positioning accuracy of the press brake tooling and backgauge. Their main difference lies in whether the program allows modification.

The numerical control system cannot modify the program, while the CNC system can modify or edit the program. The CNC system is an advanced version of the NC system that greatly improves the accuracy and efficiency of the bending operation.

The CNC system is also user-friendly and can enhance work efficiency. It contains various programming functions that can store a large number of complex bending steps, allowing for the production of large quantities of complex workpieces faster. A good control system can optimize procedures and improve production efficiency.

However, do you know which press brake controller is the best choice? This article will introduce how to select the right press brake controller. Before starting, let’s watch the video first.

2. Different Types of Press Brake Controllers

CNC press brake controllers can generally be divided into manual and CNC controllers. The manual controller requires the operator to have a good understanding of bending parameters and requires manual adjustment and monitoring of machine operation.

The operation of manual controllers is time-consuming and has low accuracy. The CNC controller controls the operation of toolings, ram, and back gauge through computer software. Simply edit the relevant parameters to bend the workpiece accurately. CNC controllers are compatible and adaptable with various bending machines.
