Master sharpens focus on saw grinding wheels

Master Abrasives has recently released a new range of Master Sawpro grinding wheels with a high-technology bond system specially engineered for the saw-sharpening industry.

The Sawpro range of wheels uses a resin bond developed for a cool-cutting action and longer life than alternative wheels. Sawpro wheels are specially designed for the manufacturing and re-sharpening of high-speed circular saws, and sharpening the tops and faces of carbide-tipped saw teeth.
Master’s Sawpro wheels are available in superabrasive and conventional abrasive grains, in all shapes and sizes. The popular industry specifications are 14F1 CBN wheels, which are suitable for Loroch machines, and diamond wheels, which suit most Vollmer machines for top and face grinding applications.
Ian Meredith, applications engineering manager, says: “Our team has developed the Sawpro range to deliver excellent performance with a cool cut, while offering great value for money. For the 14F1 CBN and diamond wheels, we will be holding stock of the most popular wheel sizes and grades.”
Master Abrasives launched the Sawpro line of grinding wheels at the GrindTec exhibition in Germany earlier this year. The key advantages of the high-technology bond system wheels were well-received by visiting engineers who work in the saw-sharpening industry.
“There was a lot of interest shown for Sawpro grinding wheels at the GrindTec event,” says Meredith. “Industry was missing a high-quality product for saw grinding that is also cost-effective, but the Master brand now fills that gap. We can offer full support with wheel selection and trials through our dedicated applications engineering team and overseas distributors to help manufacturers achieve their saw production and re-sharpening requirements.”

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.”

MTC incubator

A 2500 sq ft product manufacturing incubator on the Manufacturing Technology Centre (MTC) campus in Coventry has been officially opened by the Chancellor of the Exchequer, the Rt Hon Philip Hammond, as he announced £780m of extra funding for innovation and technology.

The new Sopwith Building is set to provide a ground-breaking facility that will help start-ups and entrepreneurs bring innovative products to market. The three-storey building will provide incubation cells for start-ups to develop and manufacture prototypes of their products.
