Mechanized beveling
Beveled edges are normally cut using a specialized bevel torch or cutting head mounted on a CNC cutting table, pipe and tube cutter, or beam processing machine.
Traditionally, bevel cutting required considerable trial and error because of the difficulty in maintaining consistent results. However, technology such as Hypertherm’s True Bevel™ significantly improves the speed, repeatability, and accuracy of bevel cutting. This is done by embedding common parameters into software used to control the movement of the bevel cutting torch or cutting head. Hypertherm’s ProNest® software allows you to create bevel parts or automatically import from CAD. And it is the only software with full support for Hypertherm’s True Bevel technology.
Adopting automated bevel cutting supports increased productivity demands and addresses increasing labor costs and a shortage of experienced operators. It also improves accuracy and repeatability for increased throughput
Post-table beveling
Many industrial operations cut parts on mechanized CNC tables followed by post-table beveling for weld preparation using an oxyfuel torch on a carriage that follows along the edge of the plate. These edges typically require additional grinding to clean up rough spots and prepare the edges for welding – a time-consuming, labor-intensive process.
Hypertherm’s Powermax® plasma technology with an optimized track/carriage solution can deliver cutting speeds of up to 30 ipm, which is 4 times faster than oxyfuel on ½″ mild steel. In addition, plasma is faster and easier to set-up, has a smaller overall footprint, and results in a smoother cut edge so significantly less grinding is required.
