Esprit supports DED manufacturing

The DP Technology team has launched the first commercial version of Esprit CAM software that includes additive direct energy deposition (DED) cycles.

Esprit’s additive capabilities are the product of the team’s more than 35 years of experience in tool-path generation, and include the same intuitive user interface that users expect from the software. The product release includes three-axis, four-axis and five-axis DED support. Combined with subtractive processes into a single software, DP Technology brings a full spectrum of support to hybrid manufacturing. Esprit’s additive DED cycles include additive simulation and verification, as well as global support from the software’s technical teams.
Notably, DP Technology validated its post processor through collaboration with major machine manufacturers and educational nstitutions.
“For more than a decade, we’ve been working on additive manufacturing, including research on DED tool-path trajectories and AM thermal simulation,” says Frederic Vignat, head of the additive department at Grenoble University in France. “Esprit’s additive DED solution is the result of close collaboration between DP Technology and Grenoble University, a world-leading research institution on additive DED technology.”
The new additive cycle offers users a full-spectrum additive solution, from CAD file to finished part.

Mill-turn centres boost Franke

During the pandemic, with the help of machining centres from DMG Mori, German firm Franke GmbH is meeting the challenge of soaring demand for the urgent supply of system components used in medical equipment such as CT scanners.

High-end special bearings with integrated drives for CT scanners, bearings for ceiling lights in intensive care units, and special bearings for medical centrifuges and laboratory equipment, are just a few examples of the components Franke produces for manufacturers in the medical industry.
To meet the high quality that users demand, Franke relies for its production on six machining centres featuring turning capability from DMG Mori, including some with twin-pallet change and an accuracy pack. A special focus at present is on the imminent delivery of two more DMC 125 FD duoBLOCK mill-turn centres with 1,250 x 1,250 x 1,000 mm working volume.
Sascha Eberhard, managing director of Franke, says: “We are being presented with a challenge during the pandemic of ensuring uninterrupted supply of our products to vital industries, while at the same time diligently implementing social distancing and other protective measures in our factory.”
The company has used machining centres from DMG Mori since 2008 to ensure flexibility of production. Depending on the type of product, batch sizes are between 1 and 1000-off per project. Workpiece materials range from diverse types of wire, through aluminium, brass and cast steel, to plastics and carbon fibre.
One of the two recently ordered DMC 125 FD duoBLOCK machines will be equipped with the DMG Mori ‘gearSKIVING’ technology cycle to enable the in-house production of straight and helical external/internal spur gears using skiving tools, reducing both cost and throughput times.

Protolabs makes £10.5m investment

One of the UK’s fastest growing digital manufacturers has begun work on a £10.5m investment that will increase its 3D printing capability by 50% to meet growing demand for this technology. Protolabs, which specialises in custom prototypes and low-volume production parts, is building a new 5000 sq m production facility in Putzbrunn, Germany, which will give customers even greater access to the firm’s automated manufacturing processes and quality systems.

Despite the COVID-19 pandemic impacting economies across Europe, construction of the new building has started, with the initial shell scheduled to be completed by the end of December, and the fit-out and machinery due to be installed in several stages, beginning in May 2021. Up to 25 further machines will be added to the existing technology, while a CNC machining centre will be installed to support the finishing of 3D printed parts for high-end applications.

Lathes breathe life into ventilator challenge

With the ramp-up of the Ventilator Challenge UK project to battle the COVID-19 pandemic, Dugard has witnessed an unprecedented surge in enquiries and sales relating to its Hanwha range of sliding-head turning centres.

As manufacturers up and down the UK switch production output to machining small turned components for ventilators, the attributes of the Hanwha range are coming to the fore. The Hanwha XE is the latest generation series, and enjoying particular success during the COVID-19 pandemic is the Hanwha XE35.
This compact heavy-duty machine is the largest in the XE series, with the facility to turn bars up to 35 mm diameter. The rigid 2750 kg XE35 is designed to machine hard materials and undertake high-volume material removal, as demonstrated by the vibration-dampening heavy cast construction, and strong, rigid tool post.
From a technical perspective, the Hanwha XE35 has a 2.2/5 kW main spindle motor and a 1.5/2.2 kW sub-spindle motor, both achieving a maximum spindle speed of 6500 rpm. The high-torque spindle motors are matched by Hanwha software, FANUC-0i CNC and gear-type modular live tooling configuration.
The tooling offers 18 positions that provide simultaneous front and rear spindle machining through a platen of five fixed tools and four driven tools in the X1 axis, with another four driven tools on the Z2-axis plane and one on the Z1 axis, accompanied by an additional four tool stations for the boring, drilling and machining of other internal features. All live tooling positions offer a high spindle speed of 6000 rpm with a 1 kW spindle motor.
The travel range of the Hanwha XE35 is generous with 210 mm in the Z1 axis, 62 mm in X1, 340 mm in Y1, 205 mm in Z2, and 312 mm in X2.
