Metal Sheet Cutter

CNC flame cutting machine combines the traditional flame cutting method with CNC automation technology, which can be used for carbon plate cutting and processing of carbon plate and general carbon plate with a thickness of more than 6mm. The flame cutting of CNC flame cutting machine is a cutting method that uses a high-temperature flame to heat a certain point on the surface of the steel plate to the ignition point, and fills it with high-pressure oxygen to burn it to form a cut.

CNC laser cutter relies on computer numerical control and computer instructions (G-code) to perform its sequence of cutting operations.

CNC laser cutting is a non-contact, thermal-based process. A CNC laser cutter features a laser head containing a laser focusing lens and a nozzle. Through the nozzle, this head and lens assembly focuses a laser beam — a column of very high-intensity light ㅡ on the workpiece, melting and cutting the workpiece to form the desired shape.

CNC plasma cutters make use of an accelerated hot plasma jet to cut through electrically conductive materials. They can be used to cut brass, copper, stainless steel, steel, aluminum, and other metals. With the use of this CNC tool, an electric plasma arc is sent via gas passing through a small opening. The gas is converted into plasma for it to pass through metals easily without much resistance. This allows for cleaner cuts to be made and results in sturdier constructions.

A high-pressure water cutter is an industrial tool that makes use of a high-pressure jet of water (or combines water with other abrasive substances) to cut materials. Hard materials like metal typically require water to be combined with abrasive substances, while softer materials can use just high-pressure water for the purpose of cutting. Garnet is the abrasive used with high-pressure water cutters to cut metal.

Laser cutting utilizes a high-powered beam of energy which cuts through metal quickly and efficiently using a CNC machine. First, the patterns which the machine will cut are designed by manufacturers on a CAD program. Then, the design is sent to the CNC machine.

Since it cuts material using thermal energy, laser cutters can move quite quickly and can cut many different angles and patterns without stopping to adjust the sheet metal. Some machines can reach a top cutting speed of 1200 inches per minute, although cutting speed depends on the type of material, the thickness of the metal, and the desired tolerance.

Since laser cutting is done automatically by a machine, it is more precise than traditional mechanical fabrication methods. The use of automation means that there is no possibility for human error in the cutting process. Laser cutting can produce parts with much tighter tolerances, with modern machines able to reach very precise measurements like .005 or even .002 inches.

Although laser cutting is not the cheapest method available, it is still quite affordable for most sheet metal fabrication. Since large laser cutting systems can be very expensive, manufacturers usually outsource their laser cutting to another company which specializes in this kind of fabrication.
