The Role of Pplate Shearing Machine: How to Use CNC Guillotine Shearing Machine?
A brief introduction of CNC guillotine shearing machine
CNC shearing machine, also known as guillotine shearing machine or dynamic shearing machine, is a kind of machine tool that uses sharp blades to cut sheet metal and other materials, controlled by CNC system, simple and intelligent help us to produce work, can be used to cut metal plate, pipe, bar and other materials.
The use of CNC shearing machine
CNC shearing machine is suitable for cutting sheet metal, plastic, rubber, wood and other materials, it can also be used for cardboard, paper and stainless steel, CNC shearing machine equipped with CNC system console, which means that your operators can be easier to operate the equipment, only need to enter a specific value, the machine can automatically complete the work. CNC shearing machine is currently any industry is the ideal cutting machine, such as need to cut metal, plastic, wood or other materials, it can do fast and accurate. These machines are commonly used in factories of auto parts, electrical appliance manufacturers and clothing manufacturers.
CNC shearing machine working process
CNC shearing machine is mainly divided into two types: plate type and shaker type. Both types use the same blade mechanism, but differ in blade design, tooling arrangement, and process control. The working process of the machine begins with the use of a square arm between the blade and the die to secure the metal plate. The upper blade holds the workpiece and moves the workpiece downward through the fixed blade to cut.
The upper and lower blades of the plate shearing machine are not completely parallel, and the Angle of the upper blade is in the range of 0.5°~ 2.5°, so the gap between the blades is necessary. The size of the gap is determined according to the thickness of the material to be cut, which will affect the flatness of the section. If the shear stress is too large, it will lead to the fracture of the material.
How to use NC shearing machine?
1. Adjust blade shear Angle
The shear Angle of blades is the Angle between blades. It can be adjusted to match various materials. The shear Angle should be set according to the thickness of the material, making your cutting process more efficient and accurate. Shear angles are measured in degrees, the most common being 0°, 22.5°, 45°, and 90°. The 0° setting is used for soft materials such as plastic or rubber, while 45° is best for metals and other hard materials.
2. Adjust the rear gauge
The back gauge is the movable plate used to hold the workpiece in place and should generally be adjusted parallel to the blade and at the same height as the blade to ensure that your material is not forced to bend when cutting. The screws at the front and back of the machine, which we usually call the feed roller, can be adjusted by loosening or tightening the feed roller. If there are no screws, it is also possible to use an adjustable wrench or pliers to turn counterclockwise until the rotation stops. In addition, you may need to tighten it slightly more with other tools such as a screwdriver or wrench.
3. Blade clearance adjustment
Just now we said that the size of the clearance will affect the flatness of the section, if the shear stress is too large, the material may break, so when using the shearing machine, it is crucial to adjust the clearance between the blades. The gap between blades is the distance between their edges, which determines how much metal can be separated per stroke of your guillotine machine. The thickness of the material will determine what gaps you should use to cut it. Cutting thin metal sheets, for example, requires almost no clearance, but if working with thick sheets, more clearance is needed to reduce wasting more material each time it passes through.
What do we need to pay attention to when operating the plate shears?
Always wear safety helmet and safety goggles when operating plate shears to avoid injury. In addition, it is important to wear gloves, make sure your clothes are not too loose or too heavy, avoid wearing sandals or flip-flops, they may cause your feet to get caught in the machine or blade, and most importantly, always pay attention to the blade of the machine, do not let it swing randomly, so as to avoid injury or serious injury.
Shearing machine are a versatile cutting tool that can be used to cut materials such as metal, wood and plastics. In the sheet metal industry, both the bending machine and the shearing machine are commonly used, but they are used for different purposes, compared to more complex functions of the bending machine, the shearing machine is more suitable for mass production of simple parts. The main advantages of using a plate shears over other types of machines are that it provides accurate cutting without compromising the integrity or quality of the material being processed, and it also saves time and cost compared to traditional methods. But shears may not be suitable for cutting hard metals, they can cause the workpiece to break and the blade to be damaged. In addition, the process may cause a small number of burrs to appear and the end to deform and is not suitable for applications requiring clean end faces. Because of these limitations, shearing may not be ideal for small batch production.
So what machine you choose for production and processing depends on your production needs and budget. After understanding these, you can visit our website, if you need to learn more about the shearing machine, press brake knowledge or buy a machine, you can also consult our sales staff, they can recommend the most suitable for your shearing machine or press brake, etc.
