Advantages of Using a Burn Table in CNC (Computer Numerical Control) Operations

When cutting the same kind of part every day or working for a customized, unique, complicated project, a burn table greatly helps a CNC operation. Overall, a burn table empowers an employee to keep the manufacturing schedule of a particular part in complete control and even think about delivering the product “Just In Time” to the final user. The other advantages of using a burn table are-

Affordability of The Final Product 

Using a burn table helps in the making the final product very affordable for the consumer. Because of the enhanced efficiency, the final product can be priced very competitively in the market. The overall price is so low that no competition can come close to the competitive price. 

Design of The Burn Table 

Some of the burn tables are in the form of an open table design and does not contain upper rails. The rails are positioned in this design and the chance of damage during the loading of materials are reduced greatly.

Most of the burn tables available in the market are built with the help of powder coating and measures 4’’ x 2.” The Z axis of the table can travel up close to 6.” Some tables are provided with an automatic torch height or anti drive control. Some of them have X and Y motors that are 570 inches and are coupled with a 28-inch motor for z-axis movement. 

Ability to Take in Large Sheets of Materials 

Burn tables can accept full material sheets. Because of this feature alone, the user can carry out effective cutting procedures. These burn tables contain cable carries that can protect all kinds of cables. Also, the ball bearings in the burn tables ensures that all the operations take place smoothly.

A Plasma Burn Table 

This type of burn table can withstand a high definition CNC cutting machine. It is primarily used for cutting stainless steel, aluminum plates, and mild steel. The maximum size of the plate that can be cut in 120” x 288.”  It handles a wide variety of thicknesses and material and that is one of the main reasons why this table is used. In addition to this, these tables can provide a high-quality cutting solution to several industries. The other advantages of using a plasm burn table to cut metal are- 
  • More than one burners can be operated for a more efficient cutting process.
  • All electrically conducive materials can be efficiently cut without any kind of problem.
  • This is the only option that is available for cutting aluminum sheets and high-alloy steel in large and medium thickness.
  • This table performs very well for medium and small-sized thickness of construction steel.
  • With a lower heat input, a high-strength construction steel can be cut comfortably.
  • The plasma table can provide high cutting speeds to the user.  The speed provided can be greater than 10 times of the conventional table.
  • This table provides very good automation solutions.
  • Plasma cutting inside water takes very little heat to cut the object. Also, the noise under water is very low compared to conventional cutting in a conventional table.
  • Both high quality and low quality of materials can be conveniently cut using the plasma table.

There are Few Disadvantages Seen When a Plasma Table is Used for Cutting

  • For dry cutting, there is a restriction in the size of the material that can be cut. For cutting under water the size of the material is restricted from 160 mm to 180 mm.
  • A wider kef is required to obtain an efficient underwater or a dry cut on a workpiece.
