FEATURE ON SAWING

Mitre-cutting bandsaw unveiled

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

High cutting outputs, simple handling and precise angular cuts are said to be among the key attributes of the HBE320-523GA mitre-cutting bandsaw.
According to the company, the HBE320-523G moves the entry-level model into a whole new performance category. A high cutting rate, simple handling and precise mitre cuts are designed to make for an attractive cost-per-cut ratio.
With a cutting range on flat materials of 520 x 320 mm, the machine can produce bilateral mitre cuts of 45° (and up to 30° on the left). The inclined position of the band wheels helps prolong the life of saw blades by reducing fatigue due to cyclical bending. Furthermore, the inclined position of the bandsaw blade allows components such as girders, angled steel and U-profiles, as well as hollow rectangular profiles, to be cut at higher speed and with less burr, says the company.
The wide range of features included on the HBE320-523G saw consist of band guiding components made of vibration-dampening grey cast iron, an electrically powered chip brush, sensitive cutting-pressure control, a wide mitre-cutting range, a spray mist cooling system and more. The cutting-pressure control system allows the saw to cut profiles and pipes at twice the speed of similar saws in a comparable price bracket, says Behringer.

Investing in technology and knowledge

Machine tool specialist Selmach says it does not just invest heavily in the machinery it sells, but in the people who sell them too. With that in mind, the company has recently undertaken a training programme with a difference.

Those in Selmach’s team who need in-depth knowledge to provide customers with the best advice already have it, so why not give them a chance to share that passion with everyone else in the team… and the company really does mean everyone.
Selmach reports that it is going to start with the Sterling SRA 440 DGSA semi-automatic double-mitring bandsaw. The company says this machine, which is from the Sterling SRA DGSA range of heavy-duty bandsaws, is very popular for medium-sized fabricators, and ideal for those who want to do bigger jobs. Investing in a Sterling SRA 440 DGSA also represents a genuine step up from the Bianco 440MS.
According to Selmach, the SRA-440 is built to process high tonnage, and it does just that, for some of the country’s largest and most successful companies. Capacity is 610 x 440 mm, and there is a 34 mm blade, carbide blade guides and double mitre with infeed/outfeed roller track.
After the cut, the blade keeps rotating as the bow returns to ensure it is not pinched, while also cleaning off any excess swarf to eliminate the risk of jamming. In addition, the optional spray mist attachment keeps everything cool by spreading the coolant more evenly, and the large-capacity coolant tray with gauze filter ensures any swarf does not find its way to undesirable places.

Investment aids blade sharpening

The DCM Company from Hwaseong, South Korea manufactures high-precision circular saw blades, as well as special purpose cutters and circular knives.

Products are supplied worldwide to all industries, such as steel pipe production, automotive manufacture, shipbuilding and aerospace. The company uses a dozen Vollmer machines for manufacturing its carbide-tipped circular saw blades, with some of its most recent recent acquisitions including the CHD, CHF and CHP models for single set-up processing. In combination with an ND handling system and appropriate loading carriage for automatic tipping, the machines are ready to use around the clock.
“At the end of the 1970s, I was teaching at a vocational school and noticed that our circular saw blades were always blunt when sawing metal cylinders, and often broke,” states An Youngmoon, managing director and founder of DCM. “This was my motivation to develop high-quality circular saw blades that permanently withstand the tough conditions of metal cutting.”
The idea soon led to the development of the first high speed steel circular saw blades manufactured by DCM. By the beginning of the 1990s, the company had developed carbide-tipped circular saw blades. From the outset, the company relied on sharpening machines from Vollmer.
“South Korea has developed into a high-end market for sharpening machines in the metals and composites sector, and the demand for service and user support is growing,” states Dr Stefan Brand, CEO of the Vollmer Group. “With the subsidiary we set up in Seoul in 2016, we can look after customers such as DCM even more intensively and competently than before.”

Edmo Group boosts productivity with mitre saw

The Edmo Group – specialists in aluminium extrusion profiles, aluminium fabrication and powder coatings – has recently purchased a Mecal SW453 Reverse double mitre saw from Addison Saws.

Edmo operates out of two locations – Ross-on-Wye and Wednesbury – and it was the need to further increase and improve upon its current mitring process that prompted the purchase of the new double mitre saw.
“The amount of mitring operations we have to apply are extensive,” states managing director David Ashton, “and looking at key ways in which we can improve that process, as well as increase productivity, is key for us as we look to further our impact on a competitive market. We were highly impressed with the capabilities of the Mecal and saw for ourselves how the machine handled complex operations, which in turn led us to make the purchase. In addition, we were very pleased with how smoothly the installation and commissioning of the Mecal proved to be.”
The Mecal is a double mitre saw with pneumatic positioned inward/outward tilting heads that offer a range of -22.5° to +135°, together with mechanical stops for intermediate angles. A large sector plate ensures accurate angle settings, with default positions set at 90° and 45°. The control system with graphical display and its USB data storage is easy to use for either quick random cuts or pre-programmed cuttings.
“Edmo’s strength lies in its ability to project manage complete turnkey supply solutions and, although it’s early days, we are confident that the Mecal will no doubt lead to increased productivity across our aluminium extrusion division,” says Ashton.

Automatic straight-cutting bandsaw released

Meba Saw has introduced the MEBAmat 330, an automatic straight-cutting bandsaw with 330 mm capacity. Available in the UK from ADS Precision, its carbide-compatible power package means the saw is designed for cutting solid bar, tubes and profiles, even from hardened, difficult-to-cut materials.

The saw runs continuously for single or multi-shift operations, whether operating two shifts, or unmanned three-shift operations. This fully enclosed saw is compact and practical. It saves space, has a larger machine door with a gas damper to keep it safely open, and allows easier access to faster blade changes and bandsaw maintenance. What’s more, Meba says that it does not sacrifice operator safety. The Plexiglas cut-outs allow safe observation and monitoring of the sawing process, while swarf and chips are prevented from exiting the machine envelope.
According to the company, a key feature of the saw is its ease of use. There is a material database in the controller which produces cutting values. With its search function, the material can be selected (length, width and other dimensions) before a saw blade and optimal cutting values are recommended. The operator can store cutting jobs with the saw’s memory function, while the machine can also import sawing programs from CAD.
The MEBAmat 330 is designed to offer solid, smooth, accurate cutting with its ball leadscrew feeding and latest linear ball guideways. Additional options include laser-monitored height detection and material width collision detection.
