More fexibility, even for small and medium batches

Schwäbische Werkzeugmaschinen (SW), a manufacturer of multi-spindle machining centres for the large-scale production of metal components, will give a world premiere of its new BA 711 Space will take place at the AMB 2022 trade fair in Stuttgart later this month. The new system is of interest for the production of battery housings, vehicles for rail transport or commercial vehicles, as well as for mechanical engineering or the aerospace industry.

With the BA 711 Space, SW has expanded its machine series to include single-station machines without a double swivel beam. Instead of the company’s typical double pivoting support, these systems only have a rotary axis with a clamping bridge. The elimination of the partition wall expands the available space enormously, allowing users to machine significantly larger parts with the same machine footprint.

SW has also broken new ground with regard to changeover flexibility and automation, among other things, by optionally equipping the workpiece carriers with integrated zero-point clamping systems. Three series of these new machining centres are currently available with different equipment variants.

Like the company’s previous machining centres of the BA 7 series, these systems are characterised by their monoblock design, high axis speeds and the high performance of the spindles. Robust ballscrews drive all three main axes. All of this means that the new systems are suitable for the medium and large series production of large-format, complex components.

The BA 711 Space, with a spindle and a workpiece carrier on the swivel bridge, and a working area of 1350 x 1175 x 650 mm, is available without the system taking up more floor space. SW’s sister model, the BA 721 Space, has the same significantly larger Y stroke of 1175 mm and can therefore also process longer components.

Schuler acquires Sovema Group

Schuler has acquired Italian mechanical engineering firm Sovema Group as part of its ambition to become a leading systems supplier of battery cell manufacturing solutions for the automotive industry and other sectors. Together with Sovema, Schuler will develop the capabilities needed to equip gigafactories for the mass production of lithium-ion batteries.

Based in Villafranca di Verona, Italy, with further sites in the USA and China, Sovema has made a name for itself in the automotive sector as well as other industries by building appropriate machines for pilot and laboratory projects, accounting for some of the world’s most prominent battery manufacturers in its customer portfolio. Furthermore, Sovema is the globe’s only supplier of automated turnkey plants for the mass production of lead-acid batteries. The Sovema Group employs just over 170 people and most recently reported sales of around €50m.

Starrett invests in laser welding technology

Starrett, a manufacturer of saws, tools and measuring instruments, has invested $1 million in German technology with the purchase of a new manufacturing line to produce bi-metal steel with laser welding. With the acquisition of this new equipment, the expectation is that the bi-metal steel production capacity will increase by around 25%. This increased production capacity will boost exports of finished saw blades, meeting demand from Europe and the rest of the world.

According to industrial director Cláudio Luis Guarnieri “the new line will start operating in September”.

Starrett also has another process to produce steel: the Bimetal Unique line. This patented process is used in the manufacturing of saw blades that have advanced technology for cutting metals and other materials. In studies developed in Starrett laboratories, a saw blade produced with Bimetal Unique steel shows 22% superior durability and a 20% faster cutting time.

Last year, Starrett invested $1 million in new machinery for this patented line. In addition to generating new business, the upgrade of the machines aligns with Starrett’s vision and values of investing resources and technology in research and development.

“When investments are made, besides increasing industry sales, it also means updated technology, consequently improving the quality of our tools for the consumer,” says Guarnieri. “Offering a product with high performance is the main goal of industry.”

How to select saw blades for material type

Choosing the best saw blade depends on compatibility. Users need to match the blade itself, its size and tooth design to the material that requires cutting. Here, Saws UK outlines a number of principles that can help simplify selection.

Carbon steel bandsaws blades are reliable in general purpose applications. These blades are available in many tooth sizes and densities, providing an excellent match for many different materials, including steel, stainless steel, mild steel and non-ferrous metals such as zinc, brass and bronze.

Bi-metal bandsaw blades offer superior strength and resilience. During manufacture, the blade of spring steel incorporates a hardened edging of high-speed cobalt steel that provides an effective, long-term cutting performance when processing all types of structural metal.

For the sawing of high-volume batches, the strong and resilient ground-tooth bandsaw blade is an effective choice. This blade type can withstand the intense heat produced when sawing continuously at high speed in materials such as stainless steel, carbon steel, aluminium and copper.

If needing a versatile bandsaw blade that can cut a wide range of diverse materials, the carbide grit edge bandsaw blade is a good pick. This blade is highly reliable, producing a fine cut finish with minimal resistance even when sawing abrasive materials that include hardened steel, cast iron, titanium and nickel-based alloys.

HSS-DMo5 circular saw blades are manufactured from a high-speed steel alloy incorporating tungsten, molybdenum and vanadium. Of particular note, these blade are steam-treated to ensure they have an extra fine surface that significantly reduces friction when cutting mild steel, stainless steel and structural steel.

TCT circular saw blades are exceptionally long-lasting. They can also withstand the extreme heat produced while operating at high speed in materials that include titanium, zirconium, nickel and cobalt.

Steel stockholder automates sawing centres

German storage and sawing equipment manufacturer Kasto has upgraded a pair of sawing cells at the Dornbirn centre of Austrian steel stockholder and distribution company EHG Stahlzentrum. The company has integrated and automated all parts of the systems, from raw material supply to the handling of containers and pallets of finished goods.

Efficiency in the processing of orders and in logistics is part of the success of EHG’s business model. The company handles about 620,000 orders every year, primarily in small batches of less than 10 items.

Christian Rüf, head of logistics systems and processes, says: “It poses quite a challenge. We’re often under enormous time pressure, as in some cases we only have one to two hours to complete an order.”

To alleviate the problem, EHG utilises advanced storage and processing technology. The Dornbirn site has eight automatic high-bay storage systems, 40 stand-alone automatic bandsaws and circular sawing machines, and two sawing centres integrated with high-bay storage so that they receive material automatically. It is these systems that have been upgraded with robotic handling and sorting.

“Our high-bay storage systems are all from Kasto,” says Rüf. “They include four UniCompact honeycomb systems for the storage of bars, tubes and profiles, as well as another for holding sheet metal. In addition, 27 Kasto automatic saws are in operation in Dornbirn, ranging from production circular saws to heavy-duty block and plate bandsaws.”

In the two automated Kasto sawing centres, all process steps now take place without any operator intervention, from feeding the raw material from the store to sorting and stacking the cut pieces. The ability to change over to a new material quickly allows the efficient processing of small batch sizes.
