Chinese Used Hydraulic Shearing Machine Specifications: What to Look For
Introduction
When it comes to cutting metal sheets quickly, safely, and precisely, few machines can match the performance of a hydraulic shearing machine. These machines are especially popular in workshops and factories where thick steel or aluminum sheets need to be cut daily. Chinese manufacturers have made a big name for themselves in producing durable, cost-effective hydraulic shearing machines. Even more, many businesses are now choosing Chinese used hydraulic shearing machines to save money while still getting reliable performance.
But how can you know which used machine is worth buying? What are the most important specifications to check? In this article, we will explain, in simple terms, the key features and specifications you need to look for when selecting a Chinese Used hydraulic shearing machine.
Understanding the Role of a Hydraulic Shearing Machine
Before talking about specifications, it's important to know what this machine does. A hydraulic shearing machine uses high-pressure hydraulic force to push a blade down and cut through metal sheets. It is mainly used in the steel industry, automotive factories, shipbuilding, and construction. It performs straight-line cuts and is designed for heavy-duty use. Choosing a Chinese used version of this machine gives you the power of a quality machine at a more affordable price.
Why Choose a Chinese Used Hydraulic Shearing Machine?
China is one of the largest machine tool manufacturers in the world. Machines from China are known for being strong, easy to repair, and affordable. Many factories around the world use these machines because they offer a good balance between quality and cost. Buying a used Chinese hydraulic shearing machine makes even more sense for small or medium-sized workshops that want to grow but don’t want to spend too much money on brand-new equipment.
1. Cutting Thickness and Length
One of the most important specifications to look for is how thick and how long the machine can cut. This depends on the blade force and the size of the working table. Some machines can cut up to 6mm thick sheets, while others can handle more than 20mm. The length of the cut can range from 1 meter to 6 meters or more.
You need to ask yourself: What kind of metal sheets will I be working with? A smaller machine might be okay for aluminum sheets, but you will need a stronger one for thick stainless steel plates.
2. Blade Gap Adjustment
The blade gap is the small space between the top and bottom blades. If this gap is too wide or too narrow, the machine won’t cut properly. A good Chinese used hydraulic shearing machine will have an adjustable blade gap system. This is especially useful when cutting different materials like mild steel, stainless steel, or aluminum.
Some machines have manual gap adjustment, while others offer automatic systems. It’s always better to look for machines where the blade gap can be set easily.
3. Cutting Angle (Shear Angle)
The cutting angle affects how smoothly and efficiently the machine can cut. A smaller cutting angle gives a cleaner cut but might reduce the machine’s capacity. A bigger angle allows cutting thicker sheets but may leave rougher edges.
Chinese used machines usually come with fixed or slightly adjustable cutting angles. When buying, check if the angle suits your material type and production needs.
4. Hydraulic System Condition
Since this is a hydraulic machine, the hydraulic system is its heart. You should inspect the condition of the oil tank, hoses, pumps, and cylinders. Ask about oil leaks, maintenance history, and whether original parts were used for repairs.
A healthy hydraulic system ensures smooth cutting action and long life. Even used machines, if maintained well, can offer years of reliable service.
5. Back Gauge Range and Type
The back gauge helps to measure how much of the sheet will be cut. It's essential for repeated cuts of the same size. Look for machines with a strong and accurate back gauge system.
Chinese used hydraulic shearing machines may come with a manual, motorized, or CNC-controlled back gauge. Choose based on your cutting needs. If you cut a lot of sheets daily, a motorized or CNC gauge will save you time and reduce errors.
6. Frame and Table Strength
Check the machine’s frame. A strong frame means less vibration and more precise cuts. Chinese machines often use welded steel frames that are both rigid and stable. Also, check the table size and support arms—it should be large enough to hold your materials safely and without bending.
Ask the seller or dealer to show you the machine while cutting. This helps you understand how stable the machine is during actual operation.
7. Control System and Automation
Used Chinese hydraulic shearing machines come with different types of control systems. Some older machines may have push-button systems, while newer ones may include touchscreens or programmable logic controllers (PLC).
If your workshop has trained operators, even a simple system is fine. But if you want better speed and repeatability, look for machines with digital control systems.
8. Blade Condition and Material
A very important part of the shearing machine is the blade. You must ask how old the blades are, and whether they are original or replaced. Chinese machines often use high-quality blades made of hardened tool steel.
Sharp blades mean clean cuts and less wear on the machine. If the blade is dull, it can cause jagged cuts or even damage the metal. Ask if spare blades are available and how easy they are to change.
9. Safety Features and Standards
Modern hydraulic shears come with important safety features like finger guards, emergency stop buttons, and foot pedals. When checking a Chinese used hydraulic shearing machine, look for these basic safety items.
Make sure the machine meets local safety rules. A safe machine protects both your workers and your investment.
10. Electrical System and Motor Specs
The machine’s electrical system should match your workshop’s power supply. Check the motor's horsepower rating—more power allows faster cutting of thick materials.
A well-maintained used machine should have no exposed wires or burned-out switches. If possible, test the motor during a cutting job to hear if it runs smoothly.
11. Maintenance Record and Age
Always ask for the machine’s maintenance history. A well-maintained machine, even if old, can work better than a newer machine that was neglected. Check if the machine was cleaned regularly, oil was changed, and blades were maintained.
Machines that were used in clean factories usually last longer than ones used in harsh environments.
12. Availability of Spare Parts
Used Chinese machines have the advantage of easy access to spare parts. China’s large machine tool industry means you can find replacement components like blades, cylinders, pumps, and control panels without too much effort.
Ask the seller if they offer support or service, and check if local suppliers have what you need.
Conclusion
Buying a Chinese Used hydraulic shearing machine is a smart move for any business looking to save money and improve productivity. But not all machines are the same. To get a good deal, you need to carefully check the specifications that matter: cutting thickness, hydraulic system, blade condition, back gauge, control systems, and overall frame strength.
With the right machine, you can boost your production, deliver cleaner cuts, and serve more clients. Make sure you test the machine, ask questions, and only buy from trusted sellers. Whether you're cutting steel, aluminum, or other metals, a well-chosen Chinese used hydraulic shearing machine will give you the power you need—at the price you can afford.
