A hydraulic shearing machine (also called a sheet metal shear or guillotine shear) cuts metal plates along a straight line by moving an upper blade down against a fixed lower blade. It is the workhorse machine for cutting sheet steel, stainless steel, aluminum and other plates into blanks before bending, welding or forming. Choosing the right shear type — guillotine or swing beam — and the right tonnage decides both cutting quality and your production cost. Hydraulic shearing machines cut plate into straight-line blanks for bending and forming. How a hydraulic shearing machine works Two hydraulic cylinders drive the upper blade holder. As the ram descends, the upper blade passes the fixed lower blade with a small clearance, shearing the

A CNC press brake retrofit means replacing the old control system, back gauge and auxiliary devices of an existing bending machine with modern CNC components — instead of buying a new machine. For sheet metal shops that already own a structurally sound press brake, retrofitting is usually the fastest way to recover positioning accuracy, add multi-step programming and bring old equipment back to a productive level. Modern CNC control systems are the core of a press brake retrofit. Why retrofit a press brake instead of buying a new one? An older press brake often has a healthy frame, cylinders and tooling — but a control system that is outdated, and a back gauge that drifts. The three biggest reasons shops

Most press brake faults are hydraulic, electrical or mechanical, and the archived maintenance manual gives a short, practical list: check the cause before acting, stop the machine immediately when anything abnormal appears, and never exceed the machine’s nominal pressure or the 1000 kN per meter die-protection limit. This guide explains the common press brake faults, their causes and the fixes from Maofeng’s archived supplier maintenance material (2026-10-09), plus the maintenance rules that prevent most of them. Common press brake faults and fixes The archived fault table lists five typical faults with their causes and removal methods: Fault symptom Cause Fix (archived) Oil pump delivers no oil; hydraulics do not move Oil pump rotation direction wrong Adjust the main motor phase

Maofeng Heavy Industry Machinery Manufacturing (马鞍山茂丰重工机械制造有限公司) is a Chinese press brake manufacturer that combines R&D, production, sales and after-sales service in one company, based in the Xin Shi Industrial Park, Bowang District, Ma’anshan City. The company profile in the archived supplier materials (2026-10-09) states that it has a 10,000 m2 standardized production workshop, a 1,100 m2 office building, a 1,200 m2 R&D building and an 85-person team. This guide explains the factory, the machining process, the quality control evidence and the service network behind a Maofeng press brake.

Sheet metal bending is the cold forming of a flat metal sheet into the product shape you need: the sheet is placed between an upper and a lower die, the machine presses the upper die down, and the sheet is bent to the target angle. Bending is one step in sheet-metal fabrication – cutting and, where needed, punching happen before or alongside it. This guide explains how bending works, the machines used (press brake, shearing machine and laser cutting machine), the materials that can be bent and how to choose the force, based on Maofeng’s archived supplier materials (2026-10-09).
