Automatic Bandsaw

Description

Behringer  has introduced the new powerful, high performance HBP-610A bandsaw 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 which provide excellent blade support. 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 cutting accuracy and long bandsaw life are due in particular to the special dual column design. "The dual column downfeed is superior to swing frame and vertical systems because it assures uniform downfeed pressure across the blade with no leverage points," said Joe Suydam, Behringer inside sales engineer. "The cutting path is shorter and therefore cutting is faster and more efficient." Suydam said that the new saw features constant chip load removal which facilitates high downfeed rates. This creates a smoother, more even surface on cut pieces according to Suydam. 

The HBP-610A bandsaw was developed for the US market to enable automated bandsawing of pipes from 0.75" to 24" in diameter. This size range is commonly used in the natural gas and oil production industries. The saw has an electronically controlled feed gripper that rapidly positions the material for cutting, then floats away from the material. This prevents the gripper from dragging against the material being cut which could interfere with accurate measuring. 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 which, over time, results in significant savings on 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 ten 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.
