news & facts fairs EMO MILANO 2021 “The magic world of metalworking” A press conference for the Chinese market was held to present EMO MILANO 2021, the world exhibition dedicated to the metalworking world, scheduled at fieramilano Rho, October 4 to 9, 2021. The conference was organised by UCIMU-SISTEMI PER PRODURRE, the Italian Machine Tools, Robots and Automation Systems Manufacturers’ Association, in cooperation with ICE-Italian trade agency, Beijing office. The speakers were Gianpaolo Bruno, trade commissioner of Beijing office and coor - dinator of ITA offices in China and Mongolia; Mao Yufeng, director of CMTBA, China Machine Tool and Tool Builders’ Association, and Luigi Galdabini, General Commissioner of EMO MILANO 2021. The meeting, which was web-streamed, involved about fifty guests among Chinese operators of the sector and representatives of the local media. Promoted by CECIMO, the European Association of Machine Tool Industries, and organised by the operational structures of UCIMUSISTEMI PER PRODURRE, EMO MILANO 2021 is the most important trade show for the operators of the world manufacturing industry. To date, there are 28 countries represented among the exhibitors of the next edition of EMO. Italy, Germany, Taiwan, Spain, Switzerland, Japan, Korea, China and the U.S.A. are the nations with the largest number of exhibiting companies. The list of registered exhibitors is increasing day by day thanks to the applications that are continuing to be sent to the Organisation Secretariat and are likely to become more numerous in the next two months, as the vaccination campaign is going on worldwide. Luigi Galdabini, general commissioner of EMO MILANO 2021, stated: “Availability of vaccines, forecasts of growth with regard to demand for machine tools in all the main areas of the world and the important incentive measures for investment in new production technologies established by the Italian government make up a really favourable context for EMO MILANO 2021, to the benefit of all those who will exhibit at the event”. According to the data processed by Oxford Economics, after the collapse in consumption registered in 2020, in 2021 the world demand for machine tools should grow by 18.4 % to 61 billion Euro, (Asia 33 billion Euro, + 15.6 %; Europe 17 billion Euro, + 23.5 %; Americas 12 billion Euro, + 19.7 %). The growth should continue in 2022. With specific reference to Europe, in 2021 both Italy (3.1 billion Euro, + 10 %) and Germany (5.7 billion Euro, + 20.9 %) should again experience a consumption increase. This trend should go on even in 2022 and 2023. Great business opportunity The Italian Government established special tax incentives, which consist of tax credit up to 50 % for investments in new machine tools, robots, automation systems, 4.0 and digital technologies, for companies investing in Italy in 2021 and 2022. This is a great business opportunity – stressed Luigi Galdabini – for all the exhibitors of all over the world and, in particular, for Chinese manufacturers that, from 2012 to 2019, reported a constant increase in the sales to Italy, reaching 70 million Euro in 2019, corresponding to 31 % more than in the previous year. The reasonable certainty that the situation in Italy will enable the exhibitions to take place without particular restrictions is proven by the fact that from September fieramilano will be the stage of leading international events. Before EMO MILANO 2021 Milano will host the fashion and furniture & design trade shows, capable of attracting thousands of visitors from any part of the world. Metal forming and metal cutting machine tools, production systems, enabling technologies, solutions for interconnected and digital factories and additive manufacturing will be in the limelight at EMO MILANO 2021, which will transform fieramilano Rho into the biggest digital factory ever set up within an exhibition centre. CECIMO has already conveyed the calendar of the world travelling exhibitions that will take place after EMO MILANO 2021. After the editions in Germany in 2023 and in 2025, EMO will be held again in Italy in 2027, thus confirming the already established period, in which Milano and Hanover will alternate in the organisation of the world machine tool trade show. further information: www.emo-milano.com 30 no. 2, April 2021
processes How to: customized gear skiving Gear skiving is over 100 years old and has recently been experiencing a renaissance as a flexible and economical alternative to other gear cutting methods. However, this complex process frequently presents great challenges to users. In addition to Skiving3, a “complete package” consisting of machine, tool and technology, Liebherr now also offers skiving tools for suppliers and contract gear manufacturers – and the appropriate consultation, if desired. The almost forgotten method of gear skiving has again gained momentum through technological advancement. Modern, fast direct drives increase the cutting speed and therefore the productivity. Low-wear cutting materials and innovative coatings ensure a long tool life. Gear skiving is considerably faster than shaping and, in many cases, more economical than broaching. The combination of crossed-axis angle, cutting speed, feeding and other customer buys a machine or tools from Liebherr, he is buying precisely this expertise and process reliability at the same time. Economical in contract manufacturing as well In times of fluctuating and generally decreasing batch sizes, gear skiving is also increasingly of interest to contract manufacturing – as a flexible and economical addition to the established gear cutting methods. However, many contract manufacturers shy away from investing in a new machine. An economical alternative is to use Liebherr tools on existing equipment. In Kempten, Liebherr uses an open concept and offers its own manufactured tools independently of the machines – with consultation on request. Liebherr also offers skiving tools independently of the machines kinematic parameters make the method very flexible: particularly for internal gears in medium batch sizes and external gears with an interfering contour, gear skiving is an additional “ace up your sleeve” in the gear cutting range. It’s all about the process So far, so good. Except that the highly complex process has to be mastered. The extreme dynamics and the complex axis arrangement demand a lot of the tool and make the method very challenging for users: “Gear skiving doesn’t forgive any errors. Deviations in manufacturing tolerances often decide whether the machining will work or not. You have to know precisely which setting screws you have to turn”, explains Dr. Oliver Winkel, head of technology application. “We at Liebherr have taken the time and can justifiably claim that we understand the process.” If the Whether they are in the supplier industry or contract manufacturing, all customers ultimately want to be optimally equipped for future market requirements and to enjoy the benefits offered by gear skiving. With the tried and tested, comprehensive all-round package Skiving3 and the open tool concept, Liebherr is a suitable partner for both groups. further information: www.liebherr.com no. 2, April 2021 31
