This issue will showcase an abundance of innovations – you’ll see how we are transforming gear-skiving into a reliable pro- cess and thus creating new gear machining opportunities. We will present our new gear-shaping machine, which was specifically designed for high precision shaping of small pinions and multiple gear teeth, meeting the high standards of the aero- space industry. To round off the gear-cutting technology topics is our new grinding heads for internal gear teeth. Our automation division has revolutionary technology to offer as well – a new im- age recognition system for our bin picking robot application. Smaller components can now be picked from deeper bins in shorter cycle times. We also showcase the newly developed LP100 loading gantry, which coincides with the “rightsizing” trend. Every user can now find the optimum size of loading gantry for their needs in Liebherr’s portfolio. We would also like to introduce a new colleague, who has joined the Management Board of Liebherr-Verzahntechnik GmbH – Dr. Hans Gronbach. Dr. Gronbach has been the Chief Development and Design Engineering Officer since June 2016, and is responsible for championing innovation.

The Authority shall develop and implement a certification and accreditation program in which private industry group and trade associations are accredited to conduct approved trade tests, and the local government units to promote such trade testing activities in their respective areas in accordance with the guidelines to be set by the Authority. TR AUTOMOTIVE SERVICING NC II 1 The Training Regulations (TR) serves as basis for: 1. Development of curriculum and assessment tools 2. Registration and delivery of training programs; and 3. Establishment of competency assessment and certification arrangements. Each TR has four sections: Section 1 Definition of Qualification - describes the qualification and defines the competencies that comprise the qualification. Section 2 The Competency Standards format was revised to include the Required Knowledge and Required Skills per element. These fields explicitly state the required knowledge and skills for competent performance of a unit of competency in an informed and effective manner. These also emphasize the application of knowledge and skills to situations where understanding is converted into a workplace outcome. Section 3 Training Arrangements – contain the information and requirements which serve as bases for training providers in designing and delivering competency-based curriculum for the qualification.

    product news Liebherr INTRODUCES INTERNAL GEAR TOOTH PROFILE GRINDING TECHNOLOGY Liebherr offers a new internal gear tooth profile grinding technology, based on its proven OPAL grinding technology, involving a belt drive spindle, which can be fitted to the standard GH 4.0 grinding head as well as to the new GH 5.0 and GH 6.0 grind- ing heads. Initially, the internal gear grinding arm is available in two different sizes, while others are to follow shortly. Custom internal gear grinding arms can be developed to match customer workpieces. Gear grinding to Liebherr quality standards is feasible for internal gears, using a range of different grinding arms that each fit the GH 4.0, GH 5.0 and GH 6.0 grinding heads. Faster switch between external and internal “Simple changeover between external and inter- nal gears takes a maximum of half an hour,” Dr. Hansjörg Geiser, head of the gear cutting machinery development and design engineering team, explains. “You detach the external gear grinding disk or worm, hang the internal gear grinding arm on the hardened stop bars to ensure repeat accuracy and fix it in place with a handful of screws, then tension the belt-drive disk and the belt and attach the cover.” Internal gears can then be ground using a grind- ing disk of 100 or 125 millimeters in diameter — a Liebherr innovation. The external gear grinding head does not have to be touched, and external gear grinding quality is again the same as before once the internal gear grinding arm has been detached. IG Opal 4.0 is the name of this innovation that functions at a maximum spindle speed of 12,000 rpm.
