5th Deburring Expo 2023: Unraveling the future of precision surface finishing and deburring technologies

As the only international trade fair for deburring technologies and precision surface finishing, Deburring Expo presents corresponding offerings in a concentrated fashion. The bilingual expert forum and various theme parks will also ensure an effective transfer of knowledge at the 5th leading trade fair at the Karlsruhe Exhibition Centre from the 10th through the 12th of October, 2023.

Components and the demands placed on their performance and reliability have changed dramatically in recent years in areas such as automotive and machinery manufacturing, medical and pharmaceuticals technology, aviation and aerospace, energy and fluid technology, as well as measuring, sensor and analysis technology. This results in new and different tasks in production steps involving deburring, edge rounding, cleaning and surface finishing. At the same time, factors such as the energy and resource efficiency of the utilised processes and their integration into interlinked production are becoming increasingly important.

As an international information and procurement platform, Deburring Expo presents new and further developed, as well as time-tested solutions to this end. The 5th trade fair for deburring technology and precision surface finishing will be held at the Karlsruhe Exhibition Centre in Germany from the 10th through the 12th of October, 2023.

“Thanks to its multi-industry, multi-material focus, Deburring Expo supports companies from all industry sectors in their search for suitable processes,” reports Gitta Steinmann, project manager at private trade fair promoters Fair Xperts. “The entire spectrum of technologies, processes, tools and services for deburring, edge rounding, cleaning and surface finishing are presented. The strengths and the limits of the various processes ranging from mechanical deburring with tools to vibratory grinding, brush deburring and blasting with solid and liquid media, right on up to machining with special technologies, can be discussed directly on site.”

The latter includes, for example, ultrasonic deburring which makes it possible to selectively deburr edges and cross-drilled holes in a fully automated, verifiable process. Since this energy-efficient process can be used for nearly any material, the range of suitable workpieces covers everything from micro parts for the optics and watchmaking industries to precision tools for machining, all the way up to components used in machinery and vehicle manufacturing weighing 15 kg.

Abrasive flow machining (AFM) also covers a very broad range of applications. It’s used for the deburring, edge rounding and polishing of components in the automotive and aviation industries, as well as in energy technology, fluid and medical engineering, extrusion technology and mould and tool making. The strengths of this process result from its ability to machine internal areas and surfaces which are difficult to access, for example in additively manufactured components.

In the case of ECM (electrochemical machining), the machining process is based on the anodic dissolution of the respective metal. Nearly all metals can be machined, in particular high-alloy materials such as nickel-based and titanium alloys, and hardened materials. In addition to deburring, selective edge rounding and polishing, the technology is also used for contouring and shaping components, as well as for burr-free drilling — for example in the aviation and aerospace industry, the automotive and toolmaking sectors, as well as in medical, microsystems and energy technology.

Laser deburring is an effective method for removing fine burrs and flakes from the outer contours of very delicate, thin-walled workpieces. Even the edges of drill-holes with diameters of just a few tenths of a millimetre can be machined. The process is also distinguished by very high processing speeds.

Thermal energy machining (TEM) permits the simultaneous removal of external and internal burrs by means of vaporisation. It’s used primarily for metal workpieces such as hydraulic manifolds, and for components made of thermoplastics from which internal and external burrs have to be removed — even from very difficult to access places.

As a complement to the exhibitor presentations, the supplementary programme at Deburring Expo offers a great deal of knowledge and know-how. Theme parks including “Automated Deburring”, “Cleaning After Deburring” and “Quality Assurance in the Deburring Process” provide information on current developments and trends. Due to its highly practical orientation, the three-day expert forum integrated into Deburring Expo is a popular source of knowledge. The focal points of the simultaneously interpreted presentations (German <> English) include fundamentals, approaches to process and cost optimisation, reports on best practice applications and current trends, as well as special content provided by the theme parks. Trade fair visitors are admitted free of charge and will also receive a free copy of the updated and expanded brochure entitled “Basic Knowledge in Deburring Technology” in German and English.
