IGOLDENCNCNC Plasma Cutting Machine Working Principle

What is CNC Plasma Cutting Machine ? cnc plasma cutter machine refers to the cutting of metals using a plasma torch controlled from a computer. Plasma cutters operate by forcing a gas or compressed air at high speeds through a nozzle. Once an electric arc is introduced to the gas, ionized gas or plasma is created, the fourth state of matter. It, in turn, cuts through the metal. CNC Plasma cutter or CNC Plasma cutting machine is mainly used for carbon steel, metal, steel and steel tube cutting with 0-50mm thickness and stainless steel 0-20mm cutting. It is a cost-effective machine for metal cutting and the price is lower than the Fiber laser or YAG laser machines but it can cut very thick of steel and with very good cutting performance.

Features of cnc plasma cutter machine:

Fully fabricated and welded steel frame

Water tray for efficient control of sparks and fumes

Removable stainless steel splash guards for side rail protection

Dropped rails for ease of loading full sheets

Gantry parking to allow full sheet to be loaded overhead

Heavy duty steel construction with durable paint finish

Linear guideways for fast accurate motion

High speed axis motors with closed loop feedback (encoder) for accuracy and reliability

Dual drive Y-axis

Rack and pinion drive system

Breakaway head eliminates damage to torch and improves safety

Laser guide for easy sheet positioning

Cut metal up to 25mm thick depending on the Hypertherm Powermax unit selected

Soft sense Digital Torch-Height Control (DTHC) Quick response for improved cut quantity and improved torch consumable life. This unique touch sensing is so soft and accurate even the thinnest sheet metal will not deflect while sensing.

How does a cnc plasma cutter machine work?

cnc plasma cutter machine are computer-run systems that have the ability to move a high-definition plasma torch in various directions by using the numerical coding that has been programmed into the computer. The high-definition plasma cutter itself operates by forcing a gas or compressed air through a nozzle at high speeds. An electric arc is then introduced to the gas, creating plasma which is able to cut through metal.

cnc plasma cutter machine are available in a range of different sizes, prices, and functionalities. These machines are highly accurate and can slice through metals at speeds of up to 500 inches per minute. While high-definition plasma cutters require a plasma gas and an assist gas to function, the type of gas will vary depending on the material being cut. Some of the gases that can be used in plasma cutting include:

Oxygen—can be used to cut mild steel up to 1 1/4 inches thick but causes rough-looking cuts in stainless steel and aluminum.

Argon and hydrogen mix—provides high-quality, smooth cuts in stainless steel and aluminum.

Compressed air—works well for low current cutting applications in metals up to 1 inch thick.

Nitrogen—can be used to cut thin stainless steel.

Methane—can be used to cut thin stainless steel.

Advantages of cnc plasma cutter machine:

Plasma cutting offers great portability. The cutter itself can be miniaturised to the point of being a handheld device and can be easily transferred between worksites. It's very easy for new employees to learn how to use a plasma cutting torch, too.

Curves, odd shapes, and multiple intersecting cuts can all be drawn by a precise beam. Plasma torches can be guided as precisely as you'd draw a line with a pencil, piloted by either manual or computer-aided control.

Plasma cutters also cut quickly and efficiently. Plasma takes one-fourth of the time of most similar techniques to make a clean break in a piece of workable metal. Fast process times also minimise the risk of metal abrasion, cuts made in error, or distortion.

Plasma cutting is versatile and compatible with a wide range of materials. These include copper, titanium, steel, iron, and alloys. Plasma cutting is also cost and energy-efficient, offering a 1:2 ratio per cut over oxygen cutting.

Plasma equipment is considered to be better value for money, as well. Plasma torches are low-maintenance, rarely requiring replacement.

Plasma cutting also relies on inert gases, making it much safer to use than oxygen-based cutting. Oxy-fuel carries a significant risk of explosion or accidental ignition while in use or storage. Conversely, plasma cutting gas is only converted into a superheated jet of plasma while the torch is actually in use.
