Parting geometry for high feeds

For parting-off at high feed rates, Horn has introduced EH geometry, a development based on the manufacturer’s S100 grooving system. The single-edge insert is available in widths of 3 and 4 mm. Notably, the stable cutting edge enables feed rates in the range of 0.25 to 0.4 mm/rev during grooving and parting, leading to fast cycle times.

High infeed requires a stable machine, as well as secure clamping of the workpiece. From a feed rate of 0.3 mm/rev, Horn recommends reducing the infeed for the first 3 to 4 mm during grooving and parting-off.

Due to their stability, S100 holders and cassettes for grooving along the Y axis are first choice when machining at these elevated feed rates. The process enables high-performance, vibration-free parting with high cutting values, leading to short machining times, reports Horn.

Especially when parting-off workpieces of larger diameter, high moments of force begin to manifest. The space available in a machine often does not allow the use of tools featuring larger cross-sections. With the new insert arrangement in the tool holder, the cutting forces are absorbed by the main cross-section of the parting tool holder, resulting in greater overall rigidity for a given tool width and, subsequently, higher feed rates. Alternatively, it is possible to deploy a narrower holder to achieve the same system rigidity.

GM CNC welcomes new starter

GM CNC, the UK’s exclusive dealer for Victor machine tools, has appointed Joe Bricknell as a new area sales representative to bolster the sales operation for this long-established brand.

Bricknell started his career as a mechanical engineering apprentice before going into a direct production role setting various types of CNC machine tools from some of the world’s most recognised brands. Taking the next step in his career, he joined a Midlands-based machine-tool company as a regional sales engineer.

Earning his spurs by selling a diverse range of machine tools and brands, Bricknell jumped at the opportunity to join GM CNC. He says: “GM CNC is a family business that has an exceptional reputation for its customer service and support. To support the UK manufacturing industry for more than 30 years with thousands of machine-tool sales and installations, and to be held in such high regard by UK manufacturers, is testament to the ethos of the company.”

Cost-effective small-batch bending

Trumpf has launched a new generation of its TruBend Cell 5000 automated bending cell. Programmed using TecZone Bend software, it takes just seconds to create bending programs, making it more affordable than ever to process small batch sizes.

The TecZone Bend programming software that comes with Trumpf’s manual bending machines is included with the TruBend Cell 5000. In most cases no manual intervention is necessary, and the software can even process multiple parts simultaneously when required. The software provides fully automated calculations of the optimum bending sequence, tooling combination and robot path. In addition, TecZone Bend ensures there are no collisions during the bending process. The programming system even generates suggestions on the optimum way to pick up blanks and stack finished parts, though users can manually adjust the suggested settings at any time.

Rapid programming is one of the keys to making automated fabrication affordable for even the smallest batch sizes. Smart automated functions free-up programmers from tedious and repetitive tasks, giving an added boost to quality.

Trumpf’s new TruBend Cell 5000 is available with bending machines from the current TruBend Series 5000. The cell comes with a dynamic and precise drive that also offers quiet and energy-efficient operation. Compared with a conventional hydraulic drive, the drive in the TruBend Cell 5000 consumes up to 50% less energy, while simultaneously increasing cell productivity.
A back-gauge system ensures blanks are in exactly the right position during the bending process. Furthermore, an angle-measuring system uses a laser to automatically check the bending angle.

Addison Forming partners with iES

Addison Forming Technologies and Innovative Engineered Solutions Inc (iES) are forming a strategic partnership whereby the former will exclusively distribute and support iES’s product range in Europe and non-exclusively in other regions globally outside of North and South America.

Addison Forming, located in Preston, is a global solutions provider of machinery, tooling, automation, robotics and process support for a wide range of tube-bending and forming applications in the automotive, aerospace and nuclear industries. The company provides a range of all-electric CNC benders with double bending head intended for the 3D bending and curling of tubes and profiles, as well as a range of electric hybrid tube benders. Furthermore, Addison Forming supplies complete turnkey packages and modular cells for high-integrity, volume production.

iES, based in Ohio, USA is a rapidly expanding manufacturer of end-forming machines and tooling for tube-end expanding, reducing, sizing, notching, trimming and perforating. The company is also a supplier of hydraulic and all-electric servo-presses. iES prides itself on its commitment to quality, responsiveness, on-time delivery and complete customer satisfaction.

The new agreement between Addison Forming and iES represents a synergistic partnership for the two companies, whose combined experience in tube forming globally is vast.

Addison Forming Technologies is a part of the Machine Technology Group of Belgrave & Powell, a specialist engineering investment group located in the UK.

Enhanced enclosures for telecom sector

RAS bending machines have increased productivity, quality and design capabilities at an Orchard Park, NY-based manufacturing facility. Diversified Control is a custom manufacturer that provides unique security enclosure solutions for the telecommunications industry. To meet its growing metal fabrication needs, Diversified Control purchased its first RAS MultiBend Center 79.22 in August 1998 and upgraded to a new model in December 2016. The company has since purchased a second automated bending machine, a RAS MiniBend Center. RAS machines are available in the UK from Press & Shear.

“These machines fabricate a significant amount of product for us,” says plant manager Tim Spencer. “We offer a broad range of custom electrical/telecom enclosures and panels, and many other associated formed parts. They are a great solution for our fabricating needs.”

Before converting to the RAS bending machines, Diversified Control used manual press brakes, making it more difficult to meet production goals.

“We had multiple employees forming identical parts on manual press brakes,” says Spencer, who adds that manual press brakes pose inherent dangers, require more workers and are not nearly as efficient.

The RAS fabrication machines allow Diversified Control to form panels at a much more efficient rate.

“There are features that can be created far more easily, especially on the MiniBend, than can be done on a manual press brake,” says Spencer, elaborating that the machine has opened the company’s “landscape to create more intricate parts”.

Diversified Control has experienced a significant increase in productivity due to the efficiency of the RAS machines.
“Having a RAS machine increases the throughput of parts significantly compared with the output of a single person,” concludes Spencer. “The MiniBend, specifically, can run without an operator.”
