Products - Best Plasma Sheet Metal Cutter for CNC Table

• Plasma cutting is a process that uses a high – velocity jet of ionized gas (plasma) to cut through electrically conductive materials, typically metals. In a CNC plasma cutter table, the plasma torch is mounted on a movable gantry.
• The CNC (Computer Numerical Control) system controls the movement of the gantry along the X, Y, and sometimes Z axes. It follows a programmed path, which is usually created using CAD (Computer – Aided Design) software. The plasma torch is then able to cut the metal precisely according to the designed shape.

• Gantry and Torch Mount: The gantry provides a stable structure for the plasma torch to move. It is usually made of strong metal to support the weight of the torch and withstand the forces during cutting. The torch mount allows for precise positioning of the plasma torch.
• Plasma Torch: This is the key component that generates the plasma arc. It consists of an electrode, a nozzle, and a power supply. The electrode ionizes the gas (usually compressed air, but other gases like oxygen or nitrogen can also be used for different cutting effects), and the nozzle shapes the plasma jet.
• CNC Controller: The brain of the operation. It reads the cutting program and sends signals to the motors that drive the gantry’s movement. It also controls the power output to the plasma torch and other parameters such as cutting speed and torch height.
• Table Surface: The table provides a flat and stable platform for the workpiece (the metal to be cut). It may have a slotted or perforated design to allow for the removal of slag (the by – product of plasma cutting) and to provide better ventilation. Some tables also have a water – filled trough beneath to cool the workpiece and reduce smoke.

• Kerf Width: The plasma cutting process leaves a certain width of cut (kerf), which needs to be accounted for in the design. The kerf width can vary depending on the power of the torch and the cutting speed.
• Bevel Cuts: While some CNC plasma cutter tables can perform bevel cuts, achieving very precise bevel angles can be more challenging compared to other methods like waterjet cutting.
• Heat – Affected Zone: The plasma cutting process generates heat, which can create a heat – affected zone (HAZ) on the metal. This can affect the material’s properties, such as hardness and microstructure, especially in heat – sensitive metals like some types of stainless steel. However, proper cutting parameters can help minimize the HAZ.

According to different requirements and configurations for power supply, plasma torch, cutting table, motor, driver, computerized control system software, machine frame, guide rail, ball screw, optional and consumble parts, CNC plasma cutters come at affordable prices ranging from $5,060 to $21,300 for every budget. An entry level plasma cutter starts at around $3,980, while a professional CNC plasma cutting machine costs anywhere from $5,600 to $17,800, and industrial CNC plasma tables are priced from $6,980 to $20,800, overall, the average cost is around $7,200 in 2024. If you buy from local shop, you can get free shipping cost, while the sale price is higher. If you want to buy cheap CNC plasma cutting table kits overseas, the fee of shipping costs, tax, and customs clearance should be included in the final price.
