Automated cnc plasma table

Types of automated CNC plasma tables

An automated CNC plasma table is a specialized cutting table and design for using plasma gas to cut metal sheets. It brings in automation by linking computer numerical control (CNC) with the cutting process. There are several types of automated CNC plasma tables, which are as follows:

• Portable CNC plasma cutter: Their size makes them more ideal for transporting and moving around the workshop. Operators can transport the table with little or no difficulty to the section of the metal to be cut. To compensate for any limitations resulting from size, the cutter is usually designed to allow for working on smaller metal sheets.
• Low bed CNC plasma table: With this type of CNC plasma table, the tabletop sits beneath the plasma torch. It works well with relatively short metal workpieces. The design of the CNC table makes it easy to load and position the metal sheets that need cutting.
• High-draft CNC plasma tables: They are the opposite of low-bed CNC plasma tables. The tabletop of the CNC plasma table is above the plasma torch. The design provides good visibility of the cutting process, which aids in making adjustments as needed.
• Roll-groove CNC plasma tables: This type incorporates rollers on the tabletop to assist in moving the metal sheets around while also facilitating the cutting process. The design is quite beneficial when working with large-diameter metal pipes.
• Hybrid CNC plasma tables: A typical feature of CNC plasma tables is the combination of plasma and oxy-fuel cutting methods. In such cases, the CNC table will come with multiple cutting heads, specialized torches, or features that allow the work to be switched easily between the two cutting methods.
• Flame CNC Plasma Table: These types of machines use a torch fueled by acetylene, oxygen, and propane to cut through metal sheets of different thicknesses. The flames, which are referred to as plasma, ionize the gas, creating an extremely hot environment that melts the metal. Flame CNC plasma tables are better suited for thicker materials.

Specifications and Maintenance of Automated CNC Plasma Tables

• Cutting Area Size: This specification will vary as per the table model. It can be the length of the X and Y axis. For example, the cutting area size might be typically 5 feet x 10 feet.
• Supported Materials: An automated CNC plasma cutting table is made to handle metal sheets, such as steel and aluminum, as well as other materials like brass, titanium, etc. It is important to note each table's specification as per its intended use and design.
• Plasma Arc Power: This might range between 25 and 100 amps, depending on the table. Users will set the power based on the thickness and material of the metal being cut. Higher power settings will be able to cut thicker metal, but lower settings may be preferable for finer cuts.
• Cutting Speed: This refers to the speed of the plasma torch as it moves across the material and ranges from 1 to 10,000 inches per minute, depending on the metal type, thickness, and the plasma cutter's power.
• Drive System: This refers to how the table functions, such as a belt, rack and pinion, or linear guideway system. The precision and reliability of cuts will depend on this.
• Controls: Plasma tables will have a controller like a handheld, PC-based, or touchscreen controller. They will also feature software for design and cutting operations. Also, with the table will come manual and other details required for the safe and correct operation of the table.
• Table Construction: The framework is designed to support a plasma cutter of a particular type and will be made of mild steel or other metals with a specific thickness. Specifications may be available in the user's manual.

Maintenance

To keep an automated CNC plasma cutting machine in good condition, it is best to use the care and maintenance tips provided in the instruction manual. Carry out the servicing and repairs following the manufacturer's guidelines.

Many parts of the plasma cutting machine need regular cleaning. The guides, rails, and racks need to be kept free of dust, burnt metal, and debris. They should be lightly lubricated to avoid corrosion, reduce friction, and enhance movement. The cutting table and workpieces should be magnet or clamped together, even as the support removes scrap metal and debris between cuts.

Both the software and hardware of the CNC plasma cutter needs to be carefully checked for connection issues and its stable operation. When cutting different types of metals, the plasma torch, its parts, and the table will require more frequent inspections and re-adjustments. All movable parts need to be lubricated, and electrical connections need to be checked.

Strictly adhere to the manufacturer's instructions and ensure all parts are used, including plasma torches, electrodes, and other items required for the smooth and safe operation of the plasma cutting table. Additionally, consider the specific requirements for maintenance of the CNC itself.

How to choose an automated CNC plasma table

• Application demands analysis:

  Before purchasing a CNC plasma cutting table, it is vital to determine the materials and shapes. If one cuts only metal with no particular requirements, a standard CNC plasma table should suffice. However, if one needs to cut large or thick metals, consider a high-power or high-capacity automated CNC plasma table.
