A story of success – the HBM 540A

hbm540aWith the HBM540A Behringer presents a fully enclosed, flexible high-performance bandsawing machine.

Based on its only recently fully re-engineered automatic HBM440A, Behringer is now presenting an addition to this high-performance machine series. The model addresses the most stringent requirements in terms of its appealing modern design and also of its superbly engineered functional characteristics. The band saw is ideally suited for the economical and precision cutting of a wide ranging variety of solid materials, pipes or profiles made of metal. In a cutting range of 540 mm in round material and 630 x 540 for squares, the HBM540A saws effortlessly and at high speed and can be used with either bimetal or carbide saw blades.

The consistently modular structure of the HBM540A guarantees a permanently high standard of quality in all the components as the sawing unit, material clamping unit and feed unit are pre-assembled separately as part of a flow assembly sequence.

An interesting feature of this machine, for example, is the facility to tilt the saw frame towards the operator, which considerably simplifies saw blade changeover. And an additional benefit for all those needing to saw an increasing amount of square or sectional material: The modular structure of the machine permits considerably simpler implementation of a saw blade incline up to 4° for the manufacturer. The machine designers attached particular importance to reducing not only cutting times but also cycle times. The result of these and other improvements are higher quality cutting results in a substantially shorter time.

The feed gripper ensures trouble-free transportation of the material to be cut, even when working with uneven stock, bundled material or heavy forgings, as the fixed gripper jaw is also moved by the material on the return stroke of the feed carriage. The material is always ideally clamped, as the clamping jaws are able to move in accordance with the material width. A standard feed gripper length of 500 mm is provided, although this can be optionally extended to 1500 and 3000 mm.

The feed gripper can be moved close up to the saw blade, allowing cut off lengths to be reduced by around 50 per cent. The gripper is mounted on linear guides and positioned by means of a frequency-controlled drive system. A vertical clamping unit can be optionally mounted. This is mounted in front of the gripper jaws and covers the entire cutting area. This offers a particular benefit when sawing layers or bundles.

The machine is equipped with generously dimensioned hinged doors which afford simple access for cleaning or maintenance work. This represents a particular benefit when changing the saw blade. The sawing unit of the HBM540A is also manufactured from a single cast frame, meaning that the machine is extremely torsion resistant even under the most extreme blade tensioning forces. Two self-adjusting chip brushes on either side of the saw blade clean it of adhering chips during the machining process.

The overall machine concept of the HBM540A was designed for trouble-free carbide capability, meaning that not only the drive system but all the relevant components have been adjusted for the use of carbide blades. Carbide saw blades offer an interesting alternative to bimetal, in particular when considering the time factor as part of the sawing process. The cutting output is many times higher, which makes a major difference to the machining times. The higher chip volume produced when working with carbide saw blades is directed into a generously dimensioned chip conveyor.

The HBM540A shows itself to be a true specialist when it comes to the sawing of aluminium. High drive output levels and cutting speeds ensure outstanding results in terms of performance, precision and surface quality. In addition, special rollers designed to cope with high speed levels guides are integrated right from the design stage to guide the saw blade for aluminium sawing. A number of supplementary functions in the machine’s electrical control system, for example the reduced speed at the start of machining on first penetration into the material, ensure perfect cutting results with aluminium every time.

A self-explanatory, graphic-supported control system paves the way for convenient and at the same time easily understandable sawing machine operation.
