Bandsaws and blades galore from Starrett

LS Starrett used the recent EMO exhibition in Hanover to showcase its bandsaw range, which extends from the portable S1005, a 4 kg, battery-operated machine with a blade speed of 170 m/min, up to the S4230, a 475 kg semi-automatic, horizontal bandsaw with a dynamometric saw-tension indicator and blade speed from 20 to 85 m/min.

Starrett also demonstrated its range of bandsaw blades and advised visitors about how to select the best one for their needs. By way of example, the company’s bi-metal blades, such as PrimAlloy, have a special high-speed edge with exclusive tooth geometry. In addition, the range has extended life treatment (EXT) functionality to ensure longevity, making it suitable for use on high-speed steel, stainless steel and titanium alloy workpieces. Alternatively, there is the Starrett carbide range, which includes the Advanz MC5 AND MC7 featuring carbide-tipped teeth for delivering precise cuts with high surface finish when cutting ferrous metals.
“We have a bandsaw that is suited for pretty much any metal-cutting application you can think of,” says John Cove, marketing manager at Starrett. “It’s easy to view all bandsaws as being alike, but it’s a dangerous trap to fall into. Having a machine that isn’t suited to your needs can impact efficiency, accuracy and even increase your energy bills. Similarly, having the right machine but the wrong blade
can be just as detrimental to your operation.”

Bi-metal saw blades introduced

Engineered to cut structural steel, tubing and bundles, large metal beams and heavy walled tubes, Lenox has introduced the HRX bi-metal bandsaw blade, an entirely new product in the company’s portfolio.

Engineered in response to increasing customer demand for cutting large structural components for commercial construction and infrastructure projects, the new Lenox HRX features a long-life blade with Lenox Power Blast technology, which is said to strengthen the blade to minimise breaks, with durable teeth for cutting large structural beams.
A further advantage is the capability to perform straight cuts through wide cross-sections. The Lenox HRX is designed to improve chip flow and reduce blade deflection for cutting efficiency, while the blade’s tooth geometry is designed to minimise edge chipping and crooked cuts. Finally, a wide kerf limits pinching in larger beams; the HRX utilises alternating set teeth, which widen the cutting channel to limit blade pinching.
“Our focus on blade durability and performance has allowed us to enhance our product offering in the bi-metal bandsaw blade market – providing greater cutting performance for our customers in these very demanding applications,” says Patrick Cowhard, senior product manager for Lenox.
The new HRX leverages the success of the Lenox Rx+ bi-metal bandsaw blade, and is designed to deliver clean cuts, efficiency and durability in large structural cutting applications. High-speed steel tooth tips combine with flexible alloy steel backing material for cost-effective performance. The HRX comes in widths from 34 to 67 mm, with extra-heavy set options available to avoid blade pinching on large material.

Danobat bandsaw offers “real value”

When Sheffield-based Special Quality Alloys chose to bring the sawing of large-diameter nickel-based superalloys in-house, the company turned to Prosaw for advice on processing these extremely tough materials.

The decision to discontinue the use of subcontractors for this purpose was made all the easier since Prosaw had already provided three Danobat bandsaws to Special Quality Alloys. With the first machine installed 12 years ago, all three bandsaws have been used for sawing slightly smaller diameter billets, yet have performed reliably. The fact that these machines have functioned so consistently over such a long period of time has inevitably resulted in the operators becoming comfortable with the Danobat saws.
This time however, billets of up to 800 mm diameter were required to be cut in an automated continuous process, so a Danobat CP800A Auto-bandsaw was specified and duly purchased by the company.
Jonathan Gillet, works manager of Special Quality Alloys explains the thinking behind the decision: “Bringing the processing of the larger diameter billets in-house has meant a good deal less handling for us, resulting in faster turnaround times since we are no longer reliant on transport contractors.
“This has benefited the company in the form of lower costs and brought the whole process entirely under our own control,” he continues. “Even though these products are notoriously difficult to cut, we have complete confidence that when we put a large diameter billet on to the Danobat machine it’s going to be cut.
“From our recent experiences we believe that Danobat machines represent real value for money,” he concludes.

Operating at speeds of up to 360 kph, shortlisted bidders for the new train fleet are: Alstom Transport, Bombardier Transportation UK Ltd, Hitachi Rail Europe, Patentes Talgo SLU and Siemens PLC. Each will be invited to tender for the contracts, which will cover the design, build and maintenance of at least 54 trains coming into service from 2026. In total, HS2 will create around 25,000 jobs and 2000 apprenticeships both directly in construction and across the UK-wide supply chain. The first trains will begin to roll off the production line in the early 2020s. Welcoming the shortlist, HS2 Minister Paul Maynard says: “Thousands of skilled British jobs and apprenticeships will be created by HS2, which gets a step closer as we reveal the companies shortlisted to build the high-speed trains.”
