Automatic Bandsaw Cuts with Reduced Vibration

Behringer’s HBP-610A is designed for the automated cutting of large pipes and solid materials ranging from 0.75" to 24" in diameter, the size range required in the oil and natural gas industries. The saw frame is a cast-iron, dual-column design utilizing positive hydraulic downfeed with a heavy-duty gearbox. The design ensures uniform downfeed pressure across the blade with no leverage points, the company says. Downfeed power can be controlled for precise, accurate blade movement and tight tolerances, and the horizontal band arrangement and hydraulically tensioned tungsten-carbide guide provide blade support. Constant chip load removal facilitates high downfeed rates for a smoother, more even surface on cut pieces.

 

The high-torque, frequency-controlled saw drive provides cutting speeds ranging from 62 to 426 sq. ft./min. The downfeed power and saw blade pressure are monitored by an automatic pressure-sensing system. The system automatically analyses cutting pressure data and makes blade pressure adjustments. The solid cast-bow frame is said to eliminate vibration and provide rigid support for blade tensioning.

 

A programmable logic controller with a BT-41 operator terminal enables data entry, storage and diagnostic display. An NC preselect stores up to 10 programs. The saw frame height is adjusted automatically to eliminate extra movement each time new material is fed into the saw. An electronically controlled feed gripper rapidly positions the material for cutting then floats away from the material, preventing the gripper from dragging across the material being cut. The clamping jaws automatically adjust to accommodate material diameter. Integrated coolant and hydraulic oil reservoirs minimize downtime for routine maintenance.
