What is Hydraulic Ironworker Machine

A hydraulic ironworker machine is a versatile piece of industrial equipment used for cutting, punching, notching, and bending various types of metal. It’s commonly found in metalworking shops, fabrication shops, and manufacturing plants. The machine operates using hydraulic power to generate the force needed for various metalworking tasks.

Multiple Functions


It can cut through flat bars, angle iron, round and square rods, and even structural steel sections with ease. This makes it useful for creating parts with precise dimensions in metal fabrication.


The machines can notch metal sheets and plates at precise angles, making it easier to fit pieces together during fabrication. This function is particularly useful for creating joints in metal structures.


Some hydraulic ironworker machines come with bending attachments or accessories that allow them to bend metal bars, tubes, and plates into various shapes. This adds to the machine’s versatility and makes it capable of handling a wide range of metalworking tasks.


In addition to cutting flat bars and plates, hydraulic ironworkers can also shear metal sections such as angle iron and channel beams. This makes it useful for quickly and accurately cutting metal stock to size.

Multiple Stations

Punching station

All metal punching operations of the ironworker machine are processed using hydraulic power, thus allowing the machine to punch very efficiently and silently. Punching is silent, powerful, and efficient. The device can either be used to hit thick metal or thin materials layered together. The waste materials come off together and in layers. The punching table consists of two parts: the first is the punching flange, and the second is the holder. There are different holders for different materials. The holder is a device that prevents the fabric from coming back with the punch after cutting.

Flat bars shearing station

The metal shear station of the ironworker machine has been equipped with simple and sturdy fixing mechanisms. Depending on the machine’s cutting capacity, You can adjust it for any steel thickness. The shearing capacity can go up to 17.71 inches in the flat bar or the cutting of corner profiles. The shearing blades, built for mass production, can be used on both sides (the upper blade has two cutting edges, and the lower blade has four cutting edges); this ensures a clean cut with minimal warping, from the total capacity to a thickness of only 1/8 inch.

Bars cutting station

Standard machines are equipped with blades for cutting U-sections. The edges are held by efficient jaws, ensuring the equipment can be arranged easily at the device without any additional adjustment. Thanks to other equipment, cutting I-section profiles, T-sections, and round and square metal bars is possible.

Notching station of ironworker machine

High Adaptability: With QBH, QCS, and other optical fiber interfaces, it can be adapted to various mainstream laser devices.

Excellent Design: Optimized optical configuration and smooth and efficient airflow design significantly improve cutting quality and efficiency.

Angle shearing station

This station enables the cutting of large angles with a capacity ranging from 17 3/4 inches to 35 1/2 inches.

The main features of a hydraulic ironworker machine can be the following:

  • Accurate & Solid steel frame
  • Adjustable stroke controls with indicators on both cylinders
  • Hydraulic system with overload protection
  • Easy to maintain
  • Can stop when emergency by using switch
  • Large flat cutting table with a ruler guide
  • 2 independent hydraulic cylinders

How Does an Ironworker Work?

A typical ironworker is comprised of a fixed frame, motor, safety shields, the metal working pieces as well as a control panel/foot pedal. Most machines are electronically and/or hydraulically controlled, and some typical working principles include:

  • The sliding plate with a cutting edge to shear metal materials against a fixed edge.
  • The movable punch to produce customizable holes in a variety of metal materials.
  • The ram or sliding arm to force metal products around a fixed point or into a die.

The single operator can complete most actions using a foot pedal or button, with many actions often repeated in quick succession for a steady production flow.

Due to the high forces required to bend and cut metal, hydraulic transmissions are common on ironworker machines.

General Capabilities of an Ironworker Machine

An ironworker machine can come in many different sizes, with the specifications of each one varying accordingly. For example, the weight of an ironworker machine can vary from 1,500kg to over 12,000kg, with the corresponding cutting force ranging from 600kN to 2500kN respectively.

Ironworkers can cut plates from 16mm thick up to 40mm thick, punch through metal up to 35mm thick and cut channel up to 300mm.

Depending on the size of the actual machine, you can feed different lengths of the metal products into an ironworker – it is possible to shear flat plates up to 750mm in length. This makes these machines incredibly versatile and a useful addition to any metal workshop.

Types of Ironworker Machine

There are two main types of ironworkers: Mechanical Ironworker machine and hydraulic ironworker machine.

Mechanical ironworkers are powered by mechanical means, typically using a flywheel and clutch system. They are often operated manually or with the help of foot pedals. These machines are reliable and efficient for smaller-scale metalworking operations.

Hydraulic ironworkers use hydraulic power to perform cutting, punching, notching, and bending operations. They offer higher precision, greater power, and increased versatility compared to mechanical ironworkers.

Hydraulic ironworkers are popular in medium to large metal fabrication shops and manufacturing plants.

The most widely used Ironworker machine is the ydraulic Ironworker Machine. Because it is suitable for processing small workpieces and can work multiple stations at a time.

Here’s a comparison between mechanical and hydraulic ironworker machines:

Power Source: Mechanical ironworkers are powered by mechanical means, typically using a flywheel and clutch system. They may require manual operation or foot pedals to activate the cutting, punching, and bending mechanisms. Hydraulic ironworkers use hydraulic power to generate the force needed for cutting, punching, notching, and bending operations. They typically offer greater control over the application of force, allowing for precise and efficient metalworking.

Speed: Mechanical ironworkers often have a fixed speed determined by the rotation of the flywheel. While they can be efficient for smaller-scale operations, their speed may be limited compared to hydraulic ironworkers. Hydraulic ironworkers often offer variable speed settings, allowing operators to adjust the speed according to the specific task and material being processed. This can result in faster overall production rates compared to mechanical ironworkers.

Maintenance: Mechanical ironworkers tend to have simpler mechanisms and require less maintenance compared to hydraulic counterparts. They may have fewer moving parts, reducing the likelihood of mechanical failures.

Cost: Mechanical ironworkers are generally less expensive upfront compared to hydraulic models. They can be a cost-effective option for smaller shops or hobbyists with lower production volumes.

Force: Mechanical ironworkers may have limitations in terms of the force they can exert compared to hydraulic models. This could affect their ability to handle thicker or harder materials efficiently.

Versatility: Hydraulic ironworkers are highly versatile and capable of performing a wide range of metalworking tasks, including cutting, punching, notching, and bending. They can handle various materials and thicknesses with ease.

Control: Hydraulic ironworkers offer precise control over the application of force, allowing for accurate and repeatable metalworking operations. This level of control is especially beneficial for tasks requiring tight tolerances or complex shapes.

Mechanical vs Hydraulic Ironworker Machine: How to Choose

Mechanical ironworkers are simpler, more cost-effective, and easier to maintain, but they may have limitations in terms of speed, force, and versatility. Hydraulic ironworkers, on the other hand, offer greater power, speed, versatility, and control, making them well-suited for heavy-duty industrial applications and tasks requiring precision and efficiency. The choice between mechanical and hydraulic ironworkers ultimately depends on factors such as budget, production requirements, and the specific needs of the metalworking operation.
