Plasma Bevel Cutting

In shipbuilding and other heavy-fabrication industries, precise bevel cuts are significant in the production of parts for welded assemblies.

Messer Cutting Systems India Pvt Ltd makes bevel cutting easy and economical. Program-controlled torches can be moved on multiple axes, while the advanced height control systems allow extremely precise bevel tolerances.

Plasma bevel cutting enables us to cut parts to size and bevel the edges in one step. This cuts your manufacturing costs by removing or reducing downstream processing. Most shapes can be bevelled, including rectangles, circles, and parts created in a CAD program. Bevelling can be performed on plate up to 3.0" (76.2mm) thick, plus or minus 52 degrees, knife edge or with a land. Factory tested and easily implemented, it takes the guesswork out of the plasma bevel-cutting process.

There are almost continuous possibilities, including bevel systems that allow automatic cutting of special bevels and programmable work-piece contours in just one production step.

The cutting head can make A, V, Y, K, X and gradual bevel cuts. Cuts may be created to 45⁰ on 2″ (50 mm) thick mild steel with the plasma bevel cutting system. Rotational axes are configured with AC servomotors and low backlash planetary gearboxes with outputs directly driven from the gearbox. No belts or tie-rods are used. Both axes travel at speeds up to 30 RPM. The RSVS-6 torch height control consists of an AC servomotor, precision ball-screw. The lifter travels at speeds up to 600 ipm (15,000 mmpm). 

Our high-definition cutting system combines Y-axis linear ways with pitch line rack and pinion drives to provide the industry’s smoothest cut edge and precise holes. Wider end trucks with a maximum guide roller spread further stabilize the X-axis motion for the ultimate cut edge performance.

Plasma cutting service is acclaimed in the market due to its smooth execution. Our esteemed patrons can avail this cutting service from us as per their need at their budgetary constraints.

Trends in bevel cutting:

• Bevelled edges are a required for weld preparation and other final assembly methods
• Increased productivity demands integrated with increasing labour costs and a shortfall of experienced operators are leading companies to adopt automated bevel cutting technologies
• Automated technologies promise improved accuracy and repeatability for increased throughput

Bevel Basics

Bevel is caused by the motion of the plasma gas as it is emitted from the nozzle. In plasma cutting it is unavoidable. High definition plasma produces fewer bevels than a standard cutter.
Torch height, air pressure, quality of air, direction of cut and consumable condition all contribute to how much bevel a cut has. 

In the process to create a plasma arc for cutting the gas must be shaped into a vortex. Because of this an arc will have a direction of rotation. This will cause one side of the cut to have more bevel than the other. To ensure that the best bevel is on the part, proper direction of travel is necessary.
