What gas does a plasma cutting machine need?

What Gas Does Plasma Cutter Use

Applicable industrial gases include argon, nitrogen, oxygen, air, water vapor and some mixed gases.

Characteristics of different industrial gases and machinable materials:

Argon: Argon is one of the most commonly used industrial gases because it has the characteristics of inertness, good stability, good conductivity, etc., and is suitable for cutting aluminum and its alloys.

Nitrogen and hydrogen: A mixture of nitrogen and hydrogen can be used to cut metal materials such as stainless steel, which can improve cutting quality and stability. The air plasma arc cutting method has poor surface quality when used to cut carbon steel, but the cutting speed is very fast. When cutting carbon steel or cast iron, adding oxygen to the air flow is more conducive to cutting.

The selection of different industrial gases varies in the following aspects:

1. Different cutting materials: Different materials require different gases.

For example, argon is suitable for cutting aluminum and its alloys, nitrogen and hydrogen mixed gas is suitable for cutting stainless steel and other metal materials, and air plasma arc cutting method has poor surface quality when used to cut carbon steel, but the cutting speed is very fast.

2. Requirements for cutting quality: Different industrial gases have different effects on cutting quality.

For example, argon gas has good incision quality when cutting aluminum and its alloys, but the cutting speed is slow; air plasma arc cutting method has poor incision quality when used to cut carbon steel, but the cutting speed is very fast.

3. Requirements for cutting speed: Different industrial gases have different effects on cutting speed.

For example, air plasma arc cutting method has a fast cutting speed when used to cut carbon steel, but the incision quality is poor; nitrogen and hydrogen mixed gas is suitable for cutting stainless steel and other metal materials, which can improve cutting quality and stability, but the cutting speed is slow.

During the plasma cutting process, it is necessary to control gas purity, flow rate and pressure and other parameters. The purity of the gas is required to be high, generally required to be above 99.9%, to ensure the stability and cutting quality of the plasma arc. The control of flow and pressure is also very important. Too large or too small will affect the stability and cutting quality of the plasma arc. Generally speaking, the control of flow and pressure needs to be adjusted according to the specific process requirements to achieve a good cutting effect.

Definition, Method, and Operation of a Laser Cutting Machine: An Overview of Laser Cutting Technology

Superstar, a leading manufacturer of laser cutting mental machines, is proud to present an in-depth overview of the definition, methods, and operations of laser cutting technology. As a pioneer in the industry, Superstar continues to innovate and offer advanced solutions in the field of CNC laser metal cutting machines, fiber laser metal cutting machines, and laser cutting metal machines.

Definition of Laser Cutting Technology

Laser cutting is a precise and efficient method used to cut materials using a laser beam. The process involves directing a high-powered laser, typically through optics, to cut various materials, especially metals, with unparalleled precision. This technology is widely utilized in industries ranging from automotive to aerospace, providing accurate cuts with minimal material wastage.

Laser represents amplification of light by excited radiation. It’s among the most widely used kinds of industrial cutting procedures. Laser cutters have gained popularity recently in schools, enterprises, hobbyists, and small workshops. Any substance can be sliced by a laser, regardless of its physical characteristics.

Method of Laser Cutting

The method of laser cutting involves focusing a laser beam onto the material to be cut. The beam melts, burns, vaporizes, or blows away the material, leaving an edge with a high-quality surface finish. There are several types of laser cutting methods, including:

CNC Laser Metal Cutting Machine: This method utilizes Computer Numerical Control (CNC) to guide the laser cutting process, allowing for intricate and highly accurate designs. CNC laser metal cutting machines are ideal for mass production and custom fabrication.

Fiber Laser Metal Cutting Machine: Fiber lasers are known for their efficiency and precision. They use optical fibers to amplify the laser beam, making them particularly effective for cutting metals such as stainless steel, aluminum, and copper. Fiber laser metal cutting machines offer higher speed and lower maintenance costs compared to traditional CO2 lasers.

Laser Cutting Metal Machine: This general category includes various types of laser cutting machines designed specifically for metal applications. These machines are capable of cutting through thick and thin metal sheets with precision, making them a versatile tool for manufacturers.

Operation of a Laser Cutting Machine

Operating a laser cutting machine requires specialized knowledge and training. The process begins with designing the desired pattern or shape using CAD software, which is then converted into a format compatible with the CNC system. The operator sets the parameters, such as laser power and cutting speed, based on the material being cut. Once the machine is calibrated, the laser cutting process begins, with the CNC system ensuring precision and consistency throughout the operation.

What are the main components of a laser cutting machine?

Laser cutting machines work on the principle of optical concepts such as reflection and magnification. The entire working process of a laser cutting machine can be divided into two separate systems – the optical system and the mechanical system.

The optical system generates a high-power laser beam for the cutting process. The mechanical system moves the laser beam to form the desired shape. The components of a basic laser cutting system include:

Power supply: The power supply helps generate the light beam.

Laser Resonator: The laser resonator is a set of mirrors. It reflects the beam from the gain medium for amplification.

Cutting Head: The cutting head focuses the laser beam on the desired point of contact.

Mechanical system: The mechanical system consists of motors and guides. They move the cutting head around the workpiece.

Motion Control System: The motion control system directs the motors and arms to move the laser in position.

These are just the basic components of a laser cutting system. Modern commercial laser cutting machines have additional components such as cooling stations, dust collectors, and dross removal systems.
