Opening up new fields of business, extending the performance spectrum or replacing an old machine are among the most frequent reasons given by users for investing in an up-to-date, more efficient mitre sawing machine.
“We deliberately integrated various features from our high-end models into this machine, raising the HBE320-523GA into a class of its own,” says the company’s CEO Christian Behringer. “High cutting output, simple handling and precise angular cutting are among the key attributes of the new bandsaw.”
With a broad application spectrum, the automatic saw covers the wide-ranging requirements of the steel construction sector and the steel industry in general. Potential users will also include those companies looking to run unmanned operations.
“Process reliability and speed play a decisive role here,” Mr Behringer explains. “The machine must be capable of sawing a wide range of different materials rapidly precisely. With a cutting range in flat materials of 520 x 320mm, bilateral mitre cuts of 45° and up to 30° on the left, this machine is the perfect all-rounder for all kinds of sawing operations.
“For reasons of cost and flexibility, profiles are generally purchased in starting lengths of up to 12m and then sawn to size”, he adds. The new mitre cutting bandsaw is easily able to cope with both structural steels and stainless steel profiles.”
In design terms, the new saw has many features in common with the HBE Dynamic series, which has already proved successful in the marketplace. The guidance system in its torsionally rigid gantry design and the bilateral bandwheel bearings ensure quiet running and precise cuts. The band guiding components are manufactured from vibration-damping grey cast iron, which not only has a highly positive impact on the quality of the cut surface, but also makes for a longer blade life. Electrically powered chip brushes clean the saw blade of chips synchronously with the saw drive system – an added bonus in terms of process reliability.
The inclined position of the bandwheels helps prolong the life of bandsaw blades by reducing fatigue due to cyclical bending. A fully automatic height adjustment facility for the saw frame and lowering of the saw when in rapid traverse help cut non-productive time to a minimum. The inclined position of the blade allows components such as girders, angled steel and U profiles as well as hollow rectangular profiles to be processed at higher speed and with less burrs.
The sawing unit is mounted for easy turning in generously dimensioned axial roller bearings and can be swivelled with a simple manual action. The closed material table simplifies material handling directly at the cutting point. The machine comes with a micro-spraying system as standard.
The machine can be supplemented as required with infeed and discharge roller conveyors, measuring devices and cross conveying systems, as well as NC angular adjustment. Behringer supplies these process-reliable customised transport solutions from its own in-house steel production facilities.
