Behringer Offers High-Production Saw for Pipe, Bar
Behringer, Morgantown, Pa., has introduced its new high-performance HBP-610A band saw for cutting large pipes and solid materials up to 24 inches in diameter. The saw frame is a cast iron, dual column design, which utilizes positive hydraulic downfeed with a heavy-duty gearbox and a high horsepower motor. The solid cast bow frame is designed to eliminate vibration and provide rigid support for blade tensioning. These design features combine to provide controlled application of downfeed power resulting in precise, accurate movement of the blade and tight tolerances. Cutting accuracy is further enhanced by the horizontal band arrangement and hydraulically tensioned tungsten-carbide guides, the company claims.
The high torque, frequency-controlled saw drive of the HBP-610A provides cutting speeds from 62-426 sq. ft./min. The downfeed power and saw blade pressure are monitored by an automatic pressure sensing system. Cutting pressure data is analyzed, and the system automatically makes blade pressure adjustments as needed to assure an optimum balance between feed rate and blade pressure. Operators can maximize material feed rates without concern of overloading the blade. This results in higher output than with saws requiring user-monitored blade pressure. Integrated coolant and hydraulic oil reservoirs assure minimum downtime on routine maintenance, which also helps to maintain high production rates, the company says.

The HBP-610A band saw enables automated band sawing of pipes from 0.75-inch to 24 inches in diameter. The saw has an electronically controlled feed gripper that rapidly positions the material for cutting. The gripper clamping jaws automatically adjust to accommodate material diameter. Because the gripper may be positioned very close to the saw blade, remnant lengths are generally shorter, saving on wasted material.
All machine functions are controlled by a programmable logic controller with a BT-41 operator terminal for data entry, storage and diagnostic display. An NC preselect provides storage for up to 10 programs. Saw frame height adjustment is automatic, which saves time by eliminating extra inches of movement each time new material is fed into the saw. The blade moves only the distance actually needed, thereby minimizing non-cutting time before high-speed precision cutting resumes.

.TRUMPF TruLaser Improves Bevels, Welds
TRUMPF’s latest advancement for laser cutting tubes and profiles is the new TruLaser Tube 7000 with Technology Package Bevel Cut. This highly productive machine is capable of cutting tubes and profiles up to 10 inches in diameter, with wall thicknesses of up to 0.3-inch thick in mild steel. It can also be used to cut stainless steel and aluminum.
The TruLaser Tube 7000 is fitted with a new pivoting laser cutting head that enables the user to make high-quality bevel cuts, slanted up to 45 degrees. The pivoting laser head is especially useful for processing tubes and profiles that will undergo subsequent welding operations. Precise miters and chamfers are cut to exact specifications for close fitting welds. This enhances structural integrity, simplifies final assembly and minimizes scrap, the company claims.
To further improve productivity, stepped rollers have been integrated to support the tube and automatically adapt to the diameter of the workpiece. Self-centering clamping jaws accommodate varying tube geometries to ensure consistent production quality. FocusLine keeps the laser’s focal positioning constant, automatically adjusting to the material’s alloy and gauge while the machine’s software adapts laser parameters based on the specific tube or profile that is being processed.

.Hypertherm HyIntensity Fiber Laser Cuts Steel, Stainless, Aluminum
Hypertherm, Hanover, N.H., offers a new 3 kW fiber laser system, the HyIntensity Fiber Laser HFL030, with a recommended cut capacity of 3/4 inch for mild steel, 1/2 inch for stainless steel, and 3/8 inch for aluminum. The HFL030 is specifically optimized for cutting applications. It comes complete with pre-developed cutting processes, and all the needed components for significantly simplified table integration and operation. As a result, the system can cut thicker materials in some cases faster than higher powered competitive systems, Hypertherm claims.
When compared with CO2 laser systems, the fiber laser cutting process significantly simplifies table design requirements and integration. Operating costs and maintenance requirements are much lower than with CO2 lasers for lower total cost of ownership, the company says. For more information, call 800-643-0030 or visit
Miyachi Unitek Corp., Monrovia, Calif., now offers its Sigma 5 Axis Fiber Laser Cutting System, designed for three-dimensional cut paths. The Sigma 5 features high speed, high precision, position-based firing laser power control and cutting features for use in cutting thin metals, the company claims.
The flexible system configuration of a two-axis rotary assembly, mounted to an XY stage, maximizes laser on-part accessibility, system simplicity, and tooling path efficiency. It is especially suited for cutting thin metals with unique cut paths, non-symmetrical features, beveled edges, off axes cutting, compound angles, and internal cut radii of less than 50 microns.
