DeburringEXPO – many innovations and know-how around deburring and for precise surfaces

With around 150 exhibitors, DeburringEXPO from October 10 to 12, 2017, at the Karlsruhe Trade Fair Grounds offers probably the most comprehensive range of solutions for the diverse tasks involved in deburring, rounding, and manufacturing precision surfaces. Complementing the presentations by companies from 16 countries, industry professionals can attend a three-day technical forum with simultaneous translation (German <> English) of lectures on innovative developments, practical examples, and benchmark solutions.

In its second edition, DeburringEXPO can boast an increase of over 40 percent in exhibitors compared to the inaugural event in 2015. The international character of the trade fair for deburring technologies and precision surfaces has also grown significantly; approximately 22 percent of the around 150 exhibitors come from abroad. "We are naturally pleased that we are receiving such great international interest from companies. Even more, we are proud to offer industry visitors from automotive manufacturing, drive and transmission technology, aerospace, mechanical engineering, medical technology, sanitary, watchmaking, tool industry, fluid technology, hydraulics, precision mechanics, microtechnology, and many other sectors the most comprehensive solutions in these areas, enabling them to gather targeted information in just one day," explains Hartmut Herdin, Managing Director of the organizing fairXperts GmbH & Co. KG.

Cross-technology offering with many innovations

The fact that exhibitors see DeburringEXPO as their industry platform is also reflected in the numerous new and further developments presented across all exhibition areas. These include, among others, robotic deburring systems for the processing of die-cast parts. Specially developed milling tools enable consistent and narrow deburring edges on aluminum castings to be reliably produced. An energy-efficient and automated blasting system for small workpieces will also be showcased. An innovative ECM system, specifically designed for surface finishing of 3D-printed metal parts and for removing micro burrs, will be on display. A new planetary vibratory finishing system with a freely controllable gear, as well as a plug-and-play vibratory finishing system for automated, high-precision individual processing of defined component areas, which can be easily integrated into production lines and taught, will also be presented. In the area of deburring tools, exhibitors will also feature innovations, for example, for automated deburring of intersecting drilled holes with defined edges in a machining process. These new tools account for increasingly complex component geometries as well as new materials and material combinations. New and further developments will also be presented in the fields of burr removal, thermal-chemical deburring (TEM), shot peening (flow grinding), plasma polishing, cryogenic and ultrasonic deburring, as well as process monitoring and quality control.

This offering is complemented by the "Component Cleaning after Deburring" theme park, which provides an overview of how deburring residues can be optimally cleaned.

Bilingual technical forum – fundamentals and expert knowledge

With its integrated three-day technical forum, which proved to be a visitor magnet at the inaugural event, DeburringEXPO also offers a platform for knowledge transfer and exchange of experience. "We have found that the demand for information and know-how on deburring technologies and the manufacture of precision surfaces is very high internationally. That is why the 29 lectures at this year's event are translated simultaneously (German <> English). Participation is free of charge for visitors," reports Hartmut Herdin. The program, coordinated by Fraunhofer IPK, covers a broad range of topics and begins on the first day with an overview lecture on deburring processes. The subsequent lectures on this day focus on mechanical deburring, including high-speed mechanical deburring with tools in highly automated processes, chip-removal deburring of workpieces and bands, the possibilities and limits of robot-based deburring, and the production of burr-free drilled holes using innovative spindle technology. The first session on the second day centers on abrasive deburring, covering topics such as cryogenic deburring and cleaning of rubber, non-ferrous metals, and technical plastic components, the key features of plasma polishing, and PECM technology as a gentle solution for the toughest tasks. The second session addresses measurement technology, with lectures on digital multi-wavelength holography for inline measurement of precision surfaces and residual burrs with micrometer accuracy, high-precision optical measurement methods for automated inspection of finely machined surfaces, and edge preparation analysis, as well as scatter light measurement devices for rapid inline surface measurement. The third day begins with a session on surface treatment, offering information on plasma-electrolytic polishing (PeP) – applied technologies and current challenges in metal deburring, developments and trends in fine surface finishing, and the abrasive creation of precision flat surfaces. The concluding lecture session focuses on component cleaning after deburring, covering topics such as multi-metal capable industrial cleaners with high particle transport capacity, targeted cleaning of internal contours/geometries with strict cleanliness requirements, and aqueous cleaning and deburring of medical and micromechanical parts.
