Quality, Optimal Edges
Breakthroughs in bevellers continue to accomplish a reduction in downstream processes. The post Quality, Optimal Edges appeared first on Fabricating & Metalworking.
Discover how advances in bevelers, such as the addition of axes for cutting units that expand the ability to tilt, deliver accurate results and speed up edge prep.
Beveling Machine for Super Duplex and Highly Alloyed Pipe
A pipe beveler for heavy-wall pipe that has a large operating range, sets up easily, self-centers using an I.D. clamp system, and can perform any angle of prep has been introduced by Esco Tool (Holliston, MA).
The Dictator II MILLHOG® Pipe Beveler is an I.D. clamping welding end prep tool designed for performing any angle of prep on super duplex and highly alloyed pipe from 4.5” I.D. to 24” O.D. Easy to set up, the self-centering tool has three wide clamps that make six points of contact on the inner wall of the pipe, squares itself, and mounts rigidly for chatter-free operation.
Suitable for use onsite or in fabrication shops, this pipe beveler is equipped with a patented safety spring hanger for easy positioning and clamping. Offered with pneumatic, electric, and hydraulic power it can incorporate four cutting blades in order to bevel, face, and bore or create 37.5º by 10º compound bevels without using cutting oils.
The World’s Most Powerful Hand-operated Plate Beveller
Heck Industries, Inc.’s (Hartland, MI) model 9000 Bevel-Mill® is a heavy-duty workhorse that can bevel up to 1-3/16” in length and bevel at a rate of 3’ per minute. Bevel angle is adjustable from 15°–to-45° and uses 5/8” square carbide inserts. It features an American made heavy duty 1-1/2” horsepower motor for continuous operation. The machine is self-supported on the workpiece and is a more effective method of beveling. The unit eliminates slow grinding and is safer for the operator with no fumes, heat or smoke. The plate beveler works with carbide materials such as mild steel, aluminum and stainless steel. Made in the USA.
3D Beveller Increases Cutting Reach Capability to 90°
The new BevelArc 3D, from Tecoi USA (Longview, TX), adds an additional axis which increases the cutting reach capability of the company’s line of plasma, oxyfuel, and laser plate processing machinery. With it, cutting heads can now be positioned from 0° to as much as 90° from a vertical position, providing more efficiency than other systems. This expanded cutting head reach capability is important for cutting and fabricating pressure vessel tank heads — as well as cutting difficult shapes and profiles from beams, plates and tubes.
With the BevelArc 3D, users can perform continuous beveling by tilting, without unnecessary torch turning. Because the torch does not move, it is not necessary to make loops to recover torch position, except in rare cases where the finishing of the corners requires it. Unlike most bevel heads limited to +/- 45°, the BevelArc 3D provides an advantage for cutting shapes that typically cannot be processed on typical thermal cutting machines.
Other advantages include easy operation and adjustment, automatic restart after collision, automatic proportional height control, and high precision roller runners. The BevelArc 3D can be easily adapted to any Tecoi USA plate processing machine.
Laser Cutter Generates Bevels While Cutting, Reducing Downstream Processes
The TRUMPF Inc. (Farmington, CT) TruLaser Series 3000 Bevel Cut Edition produces beveled cutting edges (chamfers) on the top and bottom edge of a component while cutting. This ensures optimum preparation of the welding edges and reduces downstream processes. The machine can apply chamfers to sheets of up to 1” thick and handle complex bevel geometries with ease. This solution is particularly suitable for mild and stainless steel.
For this machine, TRUMPF has equipped the cutting unit with two additional rotary axes, ultra compact drive motors, and a nozzle specifically developed for bevel cutting. Thanks to the special design, the cutting head can be tilted in all directions up to an angle of 50°. As usual, the cutting unit regulates the distance to the sheet, minimizing the risk of collision despite the steep angle. The TruLaser Series 3000 Bevel Cut Edition also comes equipped with TRUMPF collision protection, to further guarantee process reliability and prevent structural damage by avoiding collisions with tipped parts.
Due to the cutting unit’s high flexibility, users can create bevels in different geometries. In addition to the classic V and Y edges, edge geometries in which both sides of the part edge are provided with bevel cuts, also known as double V (DV) edges or X prep and double Y (DY) edges or K prep, are possible. This edge-geometry flexibility is advantageous when complex parts or groups of parts must be welded.
To meet the high demands required to prepare complex bevel cuts, TRUMPF has developed a new, particularly simple, and intuitive programming system. It contains a preselection of all the processing strategies, which the user can flexibly adapt as required. There are also predefined cutting parameters for the special bevel cut nozzles.
