What is a CNC Plasma Cutter?

A CNC plasma cutter is a metal cutting machine tool with CNC (Computer Numerical Control) that adopts plasma torch to cut different metals to different shapes and profiles, such as steel, aluminium, copper, brass, iron, galvanized sheet, etc. A CNC plasma cutter is composed of CNC controller, plasma torch, plasma power, blade plasma table or sawtooth plasma table, motor, driver, CNC plasma software, CNC operating system, ball screw, guide rail, machine frame, optional parts and consumble parts. CNC plasma cutter is also known as computer numerical controlled plasma cutter, computer-controlled plasma cutter, C ad C plasma cutter, CNC plasma table, plasma cutting table, CNC plasma machine, plasma cutting machine, CNC plasma cutting machine, CNC plasma cutting table, CNC plasma cutting system, CNC plasma cutting equipment. The most common CNC plasma tables include 4x4 table size, 4x8 table size, 5x10 table size, and 6x12 table size.

How Does a Plasma Cutter Work?

Plasma cutting is a machining method that uses the heat of a high-temperature plasma arc to melt at a metal workpiece, and to eliminate the molten metal by high-speed plasma momentum to create a slit. Plasma cutters send an electric arc by using gas like oxygen, nitrogen or compressed air. This turns the gas to plasma, as well as it promptly blasts through metal to cut it with broadband. A flame cutting torch works by adding a blast of oxygen to the flame which oxidizes the metal and turns it into slag. The plasma torch moves with a tool path directed by a computer. The term "CNC" means "Computer Numerical Control", which implies that a computer is used to control the plasma cutter motion supported G-code in a program. Compared to handheld plasma cutters, CNC plasma cutters realize automatic machining with high efficiency, high speed, and high quality.

What is a Plasma Cutter Used For?

Plasma cutters are used for cutting sheet metals, square and round metal tubes, including iron, cold rolled steel, hot rolled steel, stainless steel, galvanized steel, carbon steel, copper, brass, alloy, bronze, aluminum, titanium. Plasma cutting machines are widely used in the industries of machine tool manufacturing, petro-chemical equipment, light-industrial machinery, pressure vessel, shipbuilding, mining machinery, electric power, bridge construction, aerospace, steel structure, etc. Plasma cutters can be applied to hobbyists, home shop, home business, small shop, small business, school education, industrial manufacturing.

How to Use a Plasma Cutter & Plasma Table?

1. Manual Non-Contact Cutting.
a.Touch the torch roller to the workpiece, and adjust the distance between the nozzle and the plane of the workpiece to 3 ~ 5mm. (When the host machine cuts, the "Cut Thickness Selection" switch is upscale).
b. Turn on the torch switch to ignite the plasma arc. After cutting through the workpiece, move to the cutting direction at an even speed. The cutting speed is based on the premise of cutting through. Too slow will affect the quality of the incision and even break the arc.
c. After cutting, turn off the cutting torch switch and the plasma arc goes out. At this time, compressed air is sprayed out at a delay to cool the cutting torch. After a few seconds, the ejection stops automatically. Remove the torch to complete the entire cutting process.
2. Manual Contact Cutting.
a. The "Cut Thickness Selection" switch is at the low level, and it is used when cutting thinner plates by a single machine.
b. Place the torch nozzle at the starting point of the workpiece to be cut, turn on the torch switch, ignite the plasma arc, cut through the workpiece, and then move uniformly along the cutting direction.
c. After cutting, open and close the torch switch. At this time, the compressed air is still spraying out. After a few seconds, the spraying will stop automatically. Remove the torch to complete the entire cutting process.
3. Automatic Cutting.
a. Automatic cutting is mainly suitable for cutting thick workpieces. Select the "Cut Thickness Selection" switch position.
b. After removing the torch roller, the torch and the semi-automatic cutting machine are firmly connected, and the attachment is provided in the random accessories.
c. Connect the power of the semi-automatic cutting machine, and install the guide rail or radius rod according to the shape of the workpiece (if it is a straight-line cutting rail, if you cut a circle or arc, you should choose a radius rod).
d. If the torch switch plug is turned off, replace the remote switch plug (prepared in the accessories).
e. Adjust the appropriate walking speed according to the thickness of the workpiece. And set the "up" and "down" switches on the semi-automatic cutting machine to the cutting direction.
f. Adjust the distance between the nozzle and the workpiece to 3 ~ 8mm, and adjust the center position of the nozzle to the starting strip of the workpiece slit.
g. Turn on the remote control switch. After cutting through the workpiece, turn on the power switch of the semi-automatic cutting machine to cut. In the initial stage of cutting, pay attention to the cutting seam at any time and adjust to a suitable cutting speed. And pay attention to whether the two machines work normally at any time.
h. After cutting, turn off the remote control switch and the power switch of the semi-automatic cutting machine. At this point, the entire cutting process is completed.
4. Manual Cutting Circle.
According to the material and thickness of the workpiece, choose the single or parallel cutting method, and choose the corresponding cutting method. Tighten the cross bar in the random attachment to the screw hole on the torch holder. To the required radius and tighten, then adjust the distance from the tip to the torch nozzle according to the length of the workpiece radius (the width of the slit must be considered). After adjustment, tighten the center fastening screws to prevent loosening, and loosen the cage to tighten the knurled screws. At this point, you can cut the workpiece.
