BEHRINGER added an automated inclined magazine to its HCS-90E carbide circular cold saw, meaning the redesigned machine now meets high-production demands while minimizing the need for operator attendance. "Behringer has designed the HCS-90E saw for customers that literally need bulk cutting output in the thousands of pieces per day range," stated Joe Suydam, Behringer sales and marketing associate.

A fully automatic high-performance circular cold saw, the HCS-90E is designed to cut ferrous material at 90° in maximum yield applications. High throughput is possible thanks to the saw's inclined magazine, which holds material up to 3,500 lb. and 12 ft. long material. An optional extension expands material capacity to 20-ft. long pieces and load capacity to 5,250 lb.

Once loaded with bundles, the machine will run without interruption, cutting pre-programmed lengths, ejecting trim and remnants and channeling good cut pieces to a holding bin. This is a fully automatic function, meaning no operator is required to oversee the process. "Depending on raw bar lengths, the number of bars on the inclined magazine and the finished cut lengths," said Suydam, "it's entirely possible that an operator who loads a bundle of material at the beginning of a shift would not need to attend the machine for the remainder of that shift."

The saw is equipped with a PLC that makes it possible to program the number of pieces to be cut, product length, discharge handling, and other parameters. Integrated sensor technology helps ensure virtually non-stop throughput by detecting the leading and tail edge of the material being cut and automatically managing the feed rate. In this process, the back end of the material being cut travels past a light barrier in the machine. This signals the magazine to automatically load and stage the next bar onto a roller conveyor for entry into the saw. The machine will repeat this process until the supply of stock in the magazine has been exhausted.

The feed gripper unit is powered by a servo-driven ball screw spindle and encoder. This provides an infinitely variable feed or reverse feed rate of up to 39.3in.per second. Single-stroke capacity is 0.314-39.3 in. and multiple-stroke capacity is up to 393.6 in. (32.8 ft.)  To ensure optimal alignment of material entering the gripper clamping area, Behringer added a material shifting device to the gripper feed unit. This simplifies handling of material to help prevent marking or scratching and is beneficial for high-volume jobs.

The HCS-90E blade diameters measure from 9.8 in. (250 mm) to 12.4 in. (315 mm). The saw uses long lasting carbide-tipped disposable blades for fast, precision cutting of round stock up to 3.5 in.(90 mm) in diameter. A 10.7-HP frequency controlled saw motor enables blade speeds of 25 to 215 RPM, which facilitates cutting high-alloyed heat-resistant steels and other ferrous materials. The entire sawing head is mounted on pre-tensioned linear ways angled at 25° and the worm gear-driving the saw blade has been engineered for backlash-free motion. This enhances smooth cutting action and promotes long blade life.

Pressure-balanced, controlled blade movement helps maintain consistent production rates and improves cutting accuracy on both solid and tubular material. There is also an automatic material retract feature on the input side, and an automatic material release on the output side. This protects the carbide blade when the saw head returns to its "Home” position after completing a cut. Behringer's robust machine design helps ensure long blade life. Vibration absorbers mounted between the machine base and the sawing unit further enhance long blade life by eliminating vibrations which also enhances cut quality.
