CECIMO has created an additive manufacturing (AM) committee that will be the association’s pre-eminent platform to discuss EU policy challenges and opportunities in this rapidly evolving technology field.
The committee will act as an umbrella for all of CECIMO’s current activities (technical, statistical, economic, business and communication) as the voice of AM technologies at European level. CECIMO’s AM committee will focus on broad subjects vital for the industrialisation of AM in Europe, such as the right EU regulatory framework, workforce development, trade and AM-related statistics.

Seven of Advanced Grinding Solutions principals exhibited at the recent AMB show in Stuttgart: Bahmuller, Tschudin, Rollomatic, Magnetfinish, Gerber, Platit and HandlingTech; all of which displayed their latest technology.
For example, Bahmuller gave a worldwide debut to its Feed Loader automation system. Feed Loaders will be available from around £80,000 and come with Kawasaki robots, Siemens controls and pallet-based component magazines.
Tschudin chose the AMB show for the worldwide premier of its 350 Cube and proline 600 centerless grinding machines. The Tschudin Cube is thought to be the world’s smallest centerless grinding machine with a footprint of just 150 x 150 x 150 cm, and is designed to grind small components from 1 to 20 mm in diameter for the automotive and medical industries. In contrast, the ProLine 600 is the
new giant within Tschudin’s range of machines, weighing some 24 tonnes. The machine has a 30 kW grinding spindle as standard for grinding at 63 m/sec with the spindle producing 300 Nm of torque.
Rollomatic’s new NP3 Plus is aimed at cutting tool makers needing to cylindrically grind multiple stepped diameters on blanks prior to flute and end tooth grinding. The NP3 is based on the method of peel grinding, with the simultaneous grinding of both roughing and finishing wheels.
Magnetfinish used AMB to demonstrate a low-cost automated loader solution for its MF 63CR machine, using a Stäubli robot to handle cutting tools from Rollomatic and similar pallets.

A new co-operation agreement between two German companies, tool manufacturer Horn and lathe tool-holder producer W&F Werkzeugtechnik, aims to offer customers complete solutions covering everything from the spindle to the tool cutting edge.
Initially, the collaboration will focus on quick tool-change systems for sliding-head lathes and internally cooled whirling units. Under the deal, W&F tool solutions will be sold worldwide by Horn through its subsidiaries and sales partners in more than 70 countries. The UK subsidiary, Horn Cutting Tools, is located in Ringwood, Hampshire.

Top guitar players and metal-cutting experts share a common passion: the search for the last micron and the perfect sound.
Both of these factors can be found at Schaller, a company that produces precision mechanical components for electric guitars. To achieve the accuracy required, Schaller relies on CNC automatic lathes from Swiss manufacturer Tornos.
Schaller GmbH is a German manufacturer of hardware for musical instruments and is headquartered in Postbauer-Heng, near Nuremberg. The company develops, produces, markets and sells machine heads, bridges, vibrato systems (so-called tremolos), strap locks and other guitar accessories on a global scale.
A look at output levels reveals that the company is actually a highly prolific manufacturing enterprise. In the online shop, customers will find about 19,000 products and 160 end assemblies that consist of up to 500 individual parts having eight different surfaces each. The fact that Schaller supplies more than 1.5 million products per year is testament to factory manager Dominik Weininger and his team.
The company possesses two Swiss GT13 and two Swiss DT26 machines. For Schaller, the technical features of the GT 13 and its six-axis kinematics are the prerequisites to meet all challenges associated with the production process. The Swiss GT13 is intended for diameters up to 13 mm and has six linear axes and two C axes. These axes can be equipped with up to 30 tools, 12 of them being driven tools.
The Swiss DT26 boasts a tried and tested kinematic structure with five linear axes. Spindles can reach a power rating of over 10.5 kW. Moreover, the Swiss DT 26 is no longer restricted to mere turning and milling tasks, but can be equipped with various tool holders.
The Tornos machines at Schaller are running 24 hours a day, five days a week.

New from DMG Mori is a universal turning centre, the CLX 550, featuring robust construction, a 33 kW (40% DC/3250 rpm/630 Nm) spindle and the option of a Fanuc 3D control instead of the standard 19” SLIMline multi-touch control panel with Siemens 840D solutionline and Operate 4.7.
The lathe joins two smaller models – 350 and 450 – to expand a range that was first announced at the AMB 2016 show in Stuttgart.
Able to turn components up to 480 mm in diameter by 1225 mm long, the CLX 550 offers users a larger work area in a compact footprint of 7.4 sq m. The cast-iron bed ensures rigidity, minimises vibration and allows improved chip evacuation.
Large ballscrews, sturdy spindle bearings and a VDI 40 turret with 12 stations, live if required, ensure high productivity and accuracy, which is further promoted by feedback of axis positions via linear scales. When configured as a bar automatic, the machine produces parts up to 80 mm in diameter, or alternatively 102 mm. In terms of precision, circularity of less than 3 µm is quoted.
A choice of over 100 hardware and software options enables application-oriented specification and upgrading of the CLX 550. In addition to the optional larger bar capacity and possibility of choosing a 120 mm Y-axis, VDI 30 or VDI 50 turrets are available, as well as a tailstock and a steady rest, both of which can be programmable to facilitate the manufacture of crankshafts, for example. If a counter-spindle replaces the tailstock, six-sided machining of complex workpieces can be carried out in one hit.
