Marking a new era
SIC Marking GmbH is presenting a multilevel laser marker that can produce markings on various levels of a workpiece without having to reposition it.
The German region of Bergisches Land, comprising the three cities of Wuppertal, Solingen and Remscheid, has a long and successful history of metalworking. Yet in the shadows of this traditional industry, smaller high-tech companies are also playing an increasingly important role, enhancing the regional portfolio with intelligent and ingenious technologies. Wostor GmbH, founded in Remscheid in 1967 as a steel stamp factory and engraving shop, has developed over the years into a company specializing in pioneering solutions for product labeling and computer-controlled product identification/tracking using dot peen and laser marking systems. Now named SIC Marking GmbH, the company is at EMO Hannover 2017 to showcase an innovative laser marker that can mark various levels on a workpiece without having to reposition it.
The new multilevel laser marker is ideal for marking virtually all materials, with exceptions including gold and copper. Marking is possible even with difficult surface conditions thanks to a liquid lens in the laser marker, like those used in smartphone cameras. The liquid lens is controlled by an electrical signal and can be reshaped, thus adjusting the focal length. "Height differences up to 80 millimeters are no problem with the liquid lens," explains Christoph Lange, Head of Engineering at Sic Marking in Germany. He points out that, although a conventional laser marker is sufficient for around 90 percent of all applications, the number of special applications that involve greater space requirements for marking, complex workpiece geometries and falling cycle times is constantly increasing. The new multilevel laser marker can be used on all SIC Marking workstations that use a PC and Sic Laser Advanced software, such as the L-Box and XL-Box.

When downsizing presents big challenges
Downsizing is a growing trend for car engines, but it places ever higher requirements on the quality and precision of machined surfaces. Supfina is tackling this challenge head on at EMO Hannover 2017, where it is unveiling the new CenPro S superfinishing machine.
Virtually all automobile manufacturers are committed to downsizing because it improves efficiency. After all, reducing the displacement of an engine makes it lighter, means there is less mass to be moved, drives down friction losses and ultimately lowers fuel consumption. However, downsizing also makes crankshaft bearings smaller in diameter and width and often harder, too. This places tougher requirements on the surface of the main and pin bearings and their microgeometry. Key issues include contact ratio, roughness, defined convex transverse shapes, roundness and waviness. Another consequence is that the tools and tool holders used in the superfinishing of surfaces need to be narrower. However, they cannot afford to sacrifice any stability. Supfina Grieshaber GmbH & Co. KG is exhibiting at EMO Hannover 2017 with the new Supfina CenPro S and a clear mission. It aims to show visitors how - despite all the stringent requirements - superfinishing production operations can still be highly precise, reliable, cost effective and satisfy tolerances of a few tenths or hundredths of a micrometer for the surfaces and shape of bearings.
"Our new Supfina CenPro S meets all these requirements and delivers optimum, tried-and-tested quality, precision and cost-effectiveness," says Supfina's Managing Director, Oliver Hildebrandt. "It's a small machine, but a big achievement!" This is not least because its design is based on the tried-and-tested Supfina CenPro, which has had a leading global reputation in crankshaft machining for almost two decades and is seeing continuous development and improvement. The CenPro S is the company's response to the consistent application of downsizing principles. As workpieces must not exceed a maximum length of 500 millimeters, it is ideal for machining crankshafts for engines with up to four inline cylinders. Thanks to a stroke up to 100 millimeters (top dead center to bottom dead center) on the pin bearing finishing units and a diameter swing of up to 200 millimeters, the machine can even finish the crankshafts of high-torque V6 and V8 engines.

Premiere in the premium segment
At EMO Hannover 2017, WITTENSTEIN alpha aims to redefine the premium segment with two revamped and extended planetary gearhead series and associated angled designs.
One of the major application areas for gearheads, servo actuators and linear systems is machine tool engineering. WITTENSTEIN alpha is now presenting mechatronic solutions that are designed to meet machine requirements for dynamics and precision and offer impressive customized technology and outstanding cost-efficiency. The company is looking to use revamped and expanded gearhead series and the new carefully coordinated premium linear system to put the premium segment center stage at EMO Hannover 2017.
Five sizes each are available for the new XP+ premium gearhead and its angled variants (XPK+ and XPC+) on show in Hannover, with the sizes optimized for maximum speed and torque. The gearhead variants are suitable for much higher input speeds. According to the company, this is beneficial for the entire power train, which can be sized even more efficiently and thus harness the potential for downsizing. The existing standard ratios have also been enhanced with binary ratios (i=8, 32 and 64).
With higher speed and torque, the optimized RP planetary gearheads with low backlash also offer higher power density. The highly robust gearhead construction, which has been specially developed for linear applications using a rack and pinion system, offers impressive and unprecedented performance. This central feature for high-performance machine tool engineering delivers high-precision, high-repeatability kinematics and is now available in four sizes in the model with a bevel gear preliminary stage. Thanks to the bevel gear preliminary stage in the new RPC+ series, the same ratios are now available for the angle variants as for the coaxial RP+ version. The segment is rounded off by the RPK+ hypoid angle variant, which also has a modular design.
The newly revamped Premium linear system, which leverages the enhanced technological benefits of the enhanced planetary and right-angle gearhead series, is also being premiered at EMO Hannover 2017. The newly defined preferred linear systems (from 5 to 120 kN) are always made up of the ideal combination of gearhead, rack and pinion mechanism, and lubrication system. INIRA - the quick and straightforward assembly system for racks - can also be used as an option for all systems with optimized capacity and utilization levels for individual components, feed force, feed rate and rigidity.
The wide-ranging showcase that the innovation leader in mechatronic drive engineering and nanoprecision measuring technology is presenting under the banner "WITTENSTEIN on all axes" is rounded off by the Galaxy drive system, servo actuators in various configurations and the sub-nanometer-resolution IDS3010 measuring sensor from WITTENSTEIN's subsidiary attocube systems AG.

Stepping up a gear
Hobbing, shaping and broaching have up to now been the dominant methods used to pre-cut gears in the car and truck sectors. At EMO Hannover 2017, gearing specialist Samputensili is presenting a highly productive alternative - SCUDDING from Profilator.
Samputensili Cutting Tools from Italy has been supplying the gearing industry with a comprehensive tool and service range for the production of gears, shafts, worm gears, rotors and other helical workpieces since 1949. The company is now one of the world's leading manufacturers of precision tools for the gearing industry. Samputensili manufactures state-of-the-art precision tools at cutting-edge production facilities in various locations throughout the world. The company is at EMO Hannover 2017 to show how SCUDDING - where the tool and workpiece interact with each other, as with gearing - can offer a flexible, highly productive application for a whole host of gearing types.
Although the comparison with gearing is obvious, there is a key difference with SCUDDING - the axis cross angle between the tool and the workpiece. The axis cross angle in SCUDDING ensures relative movement along the component edges and thus chip removal. State-of-the-art machine and tool technology achieves cutting speeds up to vc = 250 m/min. However, the high spindle speeds this requires inevitably lead to high process dynamics. To eliminate the negative effects of these dynamics on the processing results, the machine needs to be adapted to the SCUDDING process. This is the only way to ensure a rigid design that delivers optimum machining results, as any vibrations are minimized. Visitors to the Samputensili stand at EMO Hannover 2017 can find out how this adaptation can be made, among other things.

Going for gold with a new technology platform
Exhibiting at EMO HANNOVER 2017, metalworking specialist Walter is one of the first companies in the world to present a new technology platform for coated indexable inserts based on CVD-titanium aluminum nitride (TiAlN) - Tiger•tec® Gold.
Through its latest innovation, Tiger•tec® Gold, Walter AG aims to deliver cutting properties that are much better than those possible with standard cutting materials and thus significantly extend tool service life and support enhanced process reliability and optimized productivity. The machining sector has been working with CVD coatings based on titanium carbo-nitride (TiCN) and aluminum oxide (Al2O3) for around two decades, but has recently hit a wall when it comes to improving the properties of these coatings. In fact, there is virtually no technical scope to further enhance the various grades of aluminum oxide in use.
That prompted the experts at Walter to embark on the development of a new generation of cutting material for coating indexable inserts. The end result of their work is now on show at EMO Hannover 2017. Tiger•tec® Gold is a completely new technological platform based on titanium aluminum nitride (TiAlN). The coating, which is extremely hard and exhibits high residual compressive stress, is claimed to be particularly suitable for milling steel and cast iron materials at medium to high machining speeds. The application engineers at Walter have been using the new WKP35G grade of Tiger•tec® Gold in special applications for some time. According to Jörg Drobniewski, head of cutting tool material development at Walter AG, the company has worked on around 50 customer applications since the spring. The results have by all accounts been impressive, showing significantly improved layer properties. According to Walter, the indexable inserts coated with Tiger•tec® Gold WKP35G demonstrated significantly enhanced wear resistance on flank faces, fewer hairline cracks and improved resistance to plastic deformation. However, it is the tool life achieved during the practical tests that is said to be most impressive - at around 80 percent longer on average.
Walter has something else truly special on offer at EMO Hannover 2017 - Speaker's Corner. Visitors here from all over the world can experience live images beamed directly from the factory of the future, with Walter experts and guest speakers giving exceptional insights and outlooks regarding the latest developments in tool innovations, Industry 4.0 and digital transformation.
