The Importance of Deburring in Modern Manufacturing
The Importance of Deburring in Modern Manufacturing Deburring’s critical impact on product quality, workplace safety, and operational efficiency cannot be overstated. In metal processing, burrs - unwanted rough edges or protrusions - are an inevitable byproduct of cutting, machining, or welding. This article highlights the essential role of deburring in ensuring high-quality manufacturing outcomes and streamlining operations. What is Deburring, and Why is It Crucial? Burrs can be classified into two primary categories: thermal burrs and mechanical burrs. Thermal burrs are created during processes involving heat, such as plasma cutting, while mechanical burrs arise from metal-to-metal contact, like punching or machining. Regardless of the source, these imperfections can have far-reaching consequences if not properly addressed. Proper deburring eliminates these rough edges, which can pose significant safety hazards and quality issues. Sharp edges can injure workers, damage manufacturing equipment, or compromise the safety of the end user. In metal fabrication facilities, workplace safety is a top priority, and deburring plays an essential role. By eliminating sharp edges, manufacturers can reduce the risk of injuries to workers handling the components. This proactive measure minimizes the likelihood of costly and concerning workers’ compensation claims and fosters a safer working environment. Deburring ensures smoother and safer handling during manufacturing and throughout the product's lifecycle. Safety isn’t just an added benefit - it’s a critical aspect of the manufacturing process that underscores the value of effective deburring. Moreover, deburring contributes to the production of high-quality components. Removing burrs promotes better welding and paint adhesion, improves the appearance of finished products, and ensures compliance with industry standards. Without deburring, paint or powder coatings may fail to adhere properly to surfaces, leading to premature wear and higher warranty claims. These claims can be costly, requiring manufacturers to replace or repair faulty parts, process returns, and potentially lose customer trust, impacting long-term business relationships. Additionally, rejected parts during quality control create inefficiencies that ripple through the production line, generating unnecessary waste. From a sustainability perspective, effective deburring helps reduce material waste and energy consumption. By ensuring components meet quality standards the first time, manufacturers can avoid rework and the environmental cost of scrapping defective parts. This aligns with broader industry trends toward sustainable manufacturing practices, as minimizing waste and optimizing processes contribute to a smaller environmental footprint. In this way, deburring not only enhances product quality and customer satisfaction but also supports a more sustainable and cost-efficient production process. Modern Solutions: Efficiency and Effectiveness The efficiency of deburring processes has advanced significantly, with modern deburring machines setting new standards. In the past, manufacturers relied on labor-intensive manual deburring methods or noisy tumbling processes that were time-consuming and often inconsistent. Tumbling, for instance, involved placing smaller parts into a large vibrating bowl filled with abrasive materials. While functional, this method creates an unpleasant work environment and lacks precision. Modern deburring machines, in contrast, provide a quieter, cleaner, and more efficient alternative. Newer systems allow manufacturers to deburr both sides of a component simultaneously in a single pass. This dual-sided deburring capability minimizes handling time, reduces operational costs, and ensures consistent quality across all parts. Additionally, advancements in edge rounding are addressing evolving industry needs. Where sharp edges were once more acceptable, many applications now require edges to be completely rounded and smoothed. This change reflects a growing emphasis on consumer safety. Beyond safety and efficiency, deburring significantly impacts the quality and performance of metal products in subsequent processes like coating, welding, and painting. Some modern deburring machines can be used to round the sharp edges, a rounded edge increases the surface and gives the coating better adhesion. This capability enhances the durability of coatings, prolonging the lifespan of components and reducing the need for rework or repairs. In welding applications, properly deburred edges improve joint quality and reduce the risk of weld defects, contributing to stronger, more reliable products. Cost Savings and Efficiency Gains One of the most compelling benefits of modern deburring techniques is their ability to reduce production costs while increasing efficiency. Manual deburring methods are not only labor-intensive but also inconsistent, leading to variability in product quality. By transitioning to automated deburring machines, manufacturers can achieve consistent, high-quality results at a faster pace. For example, dual-sided deburring in a single pass reduces the number of times a part needs to be handled, cutting down on labor costs and processing time. Over time, these efficiency gains translate into substantial cost savings, particularly for high-volume production environments. Industry Applications and Considerations Deburring is a critical process for any industry that cuts flat metal, from OEMs to job shops. Whether working with thin gauge materials or thick plates up to 4.5 inches, manufacturers across sectors benefit from advanced deburring solutions. These industries include automotive, aerospace, construction, and heavy equipment manufacturing, where precision and durability are paramount. When selecting a deburring solution, manufacturers should consider several factors: Material Type: Are multiple materials, such as carbon steel, stainless, titanium, and brass, being processed in the same machine? If so, a wet machine might be necessary to manage mixed materials effectively. Surface Finish: Does the product require a specific appearance, or is basic deburring sufficient? Processing Needs: Is dual-sided deburring required, or is single-sided processing sufficient for the application? Edge Rounding Requirements: Many modern applications demand specific edge rounding to meet safety and quality standards. By carefully evaluating these factors, manufacturers can choose the right deburring solution to meet their specific needs. Meeting Industry Standards and Regulations Compliance with industry standards and regulations is another area where deburring plays a pivotal role. For instance, many industries require specific edge finishes or paint adhesion characteristics to ensure safety, durability, and performance. LISSMAC’s machines are designed to meet these exacting requirements, offering customizable solutions for a wide range of applications. Whether it’s achieving a precise edge radius or preparing surfaces for powder coating, LISSMAC systems deliver results that align with stringent industry specifications. This capability not only simplifies compliance but also enhances the overall quality of manufactured products. LISSMAC’s commitment to innovation and efficiency sets its deburring solutions apart. By combining dual-sided processing, edge rounding, and advanced automated capabilities, these machines provide a comprehensive solution for modern manufacturing challenges. The ability to handle a wide range of materials and thicknesses ensures that LISSMAC systems are versatile enough to meet the needs of diverse industries. Deburring and Automation: A Growing Opportunity Automation is becoming increasingly relevant in the deburring world, particularly for tasks like loading and unloading parts into machines. While fully automated deburring processes are still emerging, the integration of automation technology into LISSMAC’s systems is already making strides in improving efficiency and reducing manual labor. This shift is especially significant as manufacturers seek to address labor shortages and improve productivity. Automating repetitive tasks such as part handling reduces the burden on workers and ensures a more streamlined production process.

El control inteligente revoluciona el procesamiento de chapa: LISSMAC presenta en la Blechexpo el asistente de configuración LISA para la serie SBM-L.
En la Blechexpo, LISSMAC no solo se centra en las máquinas para el procesamiento de chapa, sino también en el proceso y en cómo hacerlo más eficiente. Porque, por muy potente que sea la máquina, la carga, los errores del operador o la falta de conexión con los pasos de procesamiento anteriores y posteriores pueden ralentizar el tiempo total de procesamiento de los componentes. Por eso, la presencia en la feria se rige por el lema: «Trabaja de forma más inteligente, no más dura». Cuando se trata de eficiencia, precisión y repetibilidad en la fabricación, no hay alternativa a la tecnología de control inteligente. Con el nuevo asistente de configuración LISA, LISSMAC aborda precisamente este aspecto en las máquinas de desbarbado y rectificado de la serie SBM-L: los complejos procesos de preparación se reducen al mínimo y el manejo es más intuitivo que nunca. Precisión con solo pulsar un botón LISA registra las cinco propiedades decisivas de los componentes (aplicación, espesor de la chapa, tamaño de las piezas, material y espesor de las rebabas) y selecciona automáticamente los parámetros adecuados de la máquina. La velocidad de avance, el avance y la selección del agregado se ajustan con precisión al resultado deseado. Las recetas básicas del centro de aplicaciones de LISSMAC constituyen una base segura que se puede adaptar y almacenar individualmente según sea necesario. Los componentes recurrentes pueden incluso recuperarse directamente mediante el escaneo de un código de barras, sin necesidad de realizar un costoso ajuste manual. Además, una compensación integrada del desgaste de las herramientas garantiza que la calidad del mecanizado se mantenga constantemente alta, incluso durante largos periodos de funcionamiento. De este modo, LISA permite obtener resultados reproducibles, aumenta la productividad y, al mismo tiempo, reduce el esfuerzo de configuración. Automatización para el futuro En colaboración con Schmalz, LISSMAC ha desarrollado una célula de automatización que se encarga por completo de la carga de las máquinas SBM-L. Con la robótica más moderna, software basado en IA y sensores de visión 3D, el sistema detecta los componentes con precisión y los coloca en la cinta transportadora con una pinza matricial. A continuación, se realiza el desbarbado durante el proceso en marcha, de forma rápida, fiable y sin necesidad de personal adicional. Un manejo que entusiasma También se ha rediseñado el manejo de la máquina: una interfaz de usuario visualmente atractiva hace que incluso los procesos más complejos sean fáciles de entender. Los agregados para el desbarbado o el redondeo de bordes se pueden seleccionar fácilmente con solo pulsar un botón, y las funciones clave se muestran claramente en la pantalla de inicio. Los manuales de instrucciones digitales, los diagramas de circuitos eléctricos y las listas de piezas de repuesto se almacenan directamente en el sistema de control.

Lissmac automates grinding and deburring technology with partners
Automated processes ensure efficiency in sheet metal processing. Take, for example, the automated ejection unit that Lissmac Maschinenbau GmbH is presenting at Euroblech. It is used to separate laser components that are attached to micro bars on the sheet metal panel. Four separately controllable gripper units equipped with a vacuum suction cup selectively remove the laser components from the scrap grid after the micro-bars have been separated by the ejection process. The components are then placed on a conveyor belt for the next process steps - deburring and edge rounding. The system does not require optical image processing as it is based on the geometry data of the cutting plan and automatically determines the required number of suction pads. It can be flexibly adapted for different sheet sizes and thicknesses. The possible component sizes in the current system version range from DIN A5 to Euro pallet format. Sheets with thicknesses from 1 mm to 8 mm and a maximum weight of 90 kg can be processed. Time-consuming manual clearing is no longer necessary. The process is decoupled from laser cutting thanks to a buffer space in the warehouse. The ejection unit can be retrofitted to existing cutting systems or high racks and can be used regardless of the manufacturer. The automation unit, which the Bad Wurzach-based machine manufacturer developed together with J. Schmalz GmbH, automates the loading of Lissmac grinding machines. The cell relies on robotics technology as well as AI software and 3D vision sensors from the automation technology manufacturer. The components are identified with the help of visual 3D component recognition from Schmalz in order to pick up unmixed components from a pallet. They are then placed on a conveyor belt using a matrix gripper. They can then be deburred in the next process step.The combination of loading robots with the vacuum grippers from Schmalz and the connection to the sanding system ensures more efficient production processes: Manual loading is reduced so that a deburring machine can be operated by a single person. The SBM-L Evo series will also be presented as a pre-series model for the first time at Euroblech. On show will be the SBM-L 1000 G1S2 Evo - a deburring machine for deburring and edge rounding on both sides of punched, laser-cut and fine plasma-cut sheets in a single work step. The new top model of Lissmac's double-sided deburring machines has been available as a series machine since April 2024 From the Lissmac product range of single-sided and double-sided grinding and deburring machines for thin and thick sheet metal processing, the SBM-L 1500 G1S2 for highly efficient double-sided deburring and edge rounding of punched, laser or HD plasma-cut parts and the SMD 35 REER (S-Edition) for uniform edge rounding on all edges up to a radius of 2 mm as well as for a non-directional finish and small parts and thin sheet metal processing will also be on show in Hanover. The SMD 123 RE will also be presented, which can be used for deburring and uniform edge rounding on all edges as well as for surface processing of workpieces made of steel, stainless steel and aluminum. Also on show will be the SBM- XS 300 G1E1 Alu Mix for deburring and even edge rounding of small parts in a single operation. Visitors are cordially invited to the Lissmac stand, Hall 14, Stand 14-K06, to find out more about proven technologies and the new features for Industry 4.0.

DIN 18220: A MILESTONE FOR FIBER OPTIC EXPANSION
DIN 18220 COMES INTO FORCEOn 28.07.2023, "DIN 18220:2023-08. Trenching, milling and ploughing methods for laying empty conduit infrastructures and fiber optic cables for telecommunications networks" was adopted. The document was ceremoniously handed over at an event on the gigabit strategy of the Federal Ministry for Digital and Transport (BMDV). According to Section 126 of the German Telecommunications Act (TKG), it is to be applied uniformly by all parties involved as a recognized technical rule from the time of publication. DIN 18220 is intended to contribute to the cost-effective acceleration and, above all, high-quality implementation of fiber optic expansion. It defines clear conditions for use and implementation and sets the legal framework for achieving a milestone in broadband and fiber optic expansion. DIN 18220 increases investment security for all parties involved, especially for telecommunications companies. To date, there have been neither standardized framework conditions nor uniform principles for the application of the trenching method. Up to now, most municipalities have mainly chosen the open construction method as the laying method for fiber optic expansion, as the minimum overlap had to be at least 60 cm before the standard. Since 2012, the TKG has permitted the use of shallow laying (trenching, shallow laying methods), which also includes non-standardized methods such as trenching. However, the process has so far had difficulty establishing itself on the market. This is primarily due to legal uncertainties for all parties involved. These are inevitably associated with the lack of binding technical specifications, in the form of a binding standard, for the use of such alternative laying methods. The difficulty lay in particular in differences between road construction authorities, contractors and telecommunications companies regarding the specific execution and implementation. As a result, there were delays in the expansion of the fiber optic infrastructure. THIS CHANGES WITH THE NEW DIN 18220Up to now, most local authorities have mainly chosen the open construction method as the laying method for fiber optic expansion, as the minimum cover had to be at least 60 cm before the standard was introduced. DIN 18220 now regulates laying methods for reduced construction depths, including diamond trenching from LISSMAC (38 cm laying depth)."With DIN 18220, fiber optic installation will not only be easier in the future, but also of higher quality, faster, more cost-effective and more resource-efficient. DIN 18220 creates the necessary legal certainty and investment security for all parties involved," said BMDV State Secretary Stefan Schnorr, describing the importance of the new standard. WHAT DIN 18220 MEANS FOR LISSMACLISSMAC has been active in diamond trenching for around 10 years. Due to our experience in the field of joint cutting, we are a long-standing member of the VDMA (German Engineering Federation) and were involved in the creation of the standard as a member of the standardization committee. We are very pleased about the recognition of the alternative laying methods for fiber optic expansion, including LISSMAC diamond trenching, as the standard creates clarity for the construction industry, all municipalities, communities and telecommunications companies.
