Wide ranging mitre sawing

With the latest automatic machine from its HBE series, Behringer says it has created the perfect way of combining the benefits of modern high-performance machines for one-off sawing tasks with the solid, tried and tested characteristics of a classical mitre saw.

“We deliberately integrated various features from our Behringer high-end models into this machine, raising the HBE320-523G into a class of its own,” says Behringer UK managing director, Simon Smith. High cutting output, simple handling and precise angular cuts are among the key attributes of the new mitre-cutting bandsaw HBE320-523G.

With its extensive application spectrum, it reliably covers the wide-ranging requirements of the steel construction sector and the steel trade. Potential users also include medium-sized operations in which the new semi-automatic HBE is required to run unmanned for part of the time.

“Process reliability and speed play a decisive role here. The machine must be capable of sawing a wide range of different materials rapidly and accurately,” Mr Smith comments. “With a cutting range in rectangular materials of 520 x 320mm, two-way mitre cuts of 45° right and up to 30° on the left, the machine is the ideal all-rounder for all kinds of sawing operations.”

He continues: “For reasons of cost and flexibility, profiles are generally purchased in stock lengths of up to 12m and then sawn to size. The new mitre cutting bandsaw is easily able to cope with both structural and solid steel together with stainless steel profiles.”

In design terms, the new mitre saw has many features in common with the HBE Dynamic series, which has already proved a success in the market. The guidance system in its torsional rigid gantry design and the bilateral band wheel bearings ensure quiet running and precise cuts. The band guiding components are manufactured from vibration-damping grey cast iron, which 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 providing optimum cleaning and swarf removal from the blade.

A major benefit of this new generation machine is the saw bow down feed that is electronically controlled via a servo ballscrew drive. As a result, constant chip load and shorter non-productive times produce faster cut times and improved blade life.

The inclined position of the band wheels 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 bandsaw blade allows components such as steel beams, angles and U profiles as well as hollow rectangular profiles to be sawn at higher speed and with minimal 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.

It can be supplemented as required with infeed and discharge roller conveyors, measuring devices and cross conveying systems, as well as NC angular adjustment. The HBE320-523G can also be supplied as an automated sawing system as a GA version.

Behringer GmbH supplies these highly process-reliable customised transport solutions from its own in-house steel production facilities in Kirchardt, Germany. Its UK operation Behringer Ltd is based in Pitstone, near Leighton Buzzard, Bedfordshire.
