An extreme environment requiring absolute reliability<\/strong><\/h2>\n

The nuclear power generation industry\u2014think of names such as EDF, Framatome, Westinghouse, and Electrabel\u2014is one of the most strictly controlled sectors in terms of quality and safety. Every component installed in a power plant, reactor, heat exchanger, or primary circuit is subject to stringent standards. The slightest failure can have major consequences for the safety, maintenance, or durability of the facilities.<\/p>\n

The mechanical parts used in this context are generally made of special or even very hard materials<\/strong>, such as Inconel<\/strong>, Zircaloy<\/strong> (zirconium<\/strong>), tungsten<\/strong>, refractory stainless steel<\/strong>, or vanadium-chromium-molybdenum<\/strong> or cobalt-chromium<\/strong> alloys. They must be resistant to corrosion, heat, radiation, and repeated mechanical stress. But beyond the properties of the materials, it is the precision of the machining<\/strong> that determines their proper functioning: micron tolerances, perfect alignment, controlled roughness, and absence of microcracks.<\/p>\n

The manufacture of such components is not possible using conventional milling or turning techniques alone. Non-traditional processes are required that are capable of respecting the geometry<\/strong>, minimizing<\/strong> residual stresses<\/strong>, and ensuring perfect traceability<\/strong>.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column width=”1\/3″][vc_single_image image=”8672″ img_size=”medium” alignment=”center” css=””][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”8668″ img_size=”medium” alignment=”center” css=””][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”8676″ img_size=”medium” alignment=”center” css=””][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=””]<\/p>\n

Electrical discharge machining and micro-machining: the solution for critical nuclear components<\/strong><\/h2>\n

Electrical discharge machining (EDM)<\/strong> offers an ideal solution for machining complex parts made of special or refractory alloys. This process involves no mechanical contact between the tool and the part, which preserves the integrity of the structure and prevents deformation. Using die-sinking EDM or wire EDM<\/strong>, it is possible to produce clean internal shapes, pockets, grooves, and deep holes with extremely fine tolerances.<\/p>\n

High-precision machining<\/strong> produces parts with exceptional surface finishes (Ra < 0.2\u00b5m), which is essential in contact areas or mechanical interfaces, such as flat and cylindrical grinding <\/strong>processes, or even better. For assembly areas, coaxiality<\/strong>, parallelism<\/strong>, and flatness<\/strong> are ensured by checks in a stabilized environment, using 3D sensors<\/strong>\u2014on a three-dimensional measuring bench\u2014or optical<\/strong> sensors<\/strong>\u2014optical coordinate control (high-precision dimensional image measurement).<\/p>\n

Micro-drilling<\/strong> is also a fundamental lever in the regulation or cooling circuits of nuclear components. It allows the production of ventilation, expansion, or fluid circulation holes with diameters of less than 0.2 mm, similar to laser machining<\/strong>, but without burrs and with excellent parallelism at high depths.[\/vc_column_text][vc_single_image image=”8680″ img_size=”medium” alignment=”center” css=””][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text css=””]<\/p>\n

Mecasoft: proven expertise in the machining of complex nuclear components<\/strong><\/h2>\n

Mecasoft has long been a trusted partner for parts suppliers in the nuclear energy sector. Its experience in machining complex technical parts<\/strong>, combined with a rigorous quality<\/strong> culture and advanced dimensional control<\/strong> methods, enables it to meet the most stringent requirements of the sector.<\/p>\n

The company specializes in the production of single parts<\/strong> or small series<\/strong>, always based on technical drawings provided by the customer<\/strong>. Each production run is accompanied by complete documentation: material certificate, inspection report, self-inspection sheet, process traceability. These series are sometimes reproduced over many years, requiring exemplary traceability.<\/p>\n

Thanks to its modern machinery<\/strong>, Mecasoft is able to consistently machine parts with tolerances of <5 \u00b5m, even in difficult materials such as Inconel or Hastelloy. Its expertise in electroerosion<\/strong>, micro-drilling<\/strong>, and heat and surface treatments makes it a preferred subcontractor in this highly regulated field.[\/vc_column_text][\/vc_column][\/vc_row][vc_row link=”url:https%3A%2F%2Fwww.mecasoft.be%2Fcontact%2F|title:Contact” smooth_scroll=”n” size=”big” btn_width=”btn_auto_width” custom_btn_width=”200″ button_alignment=”btn_center” animation=”” font_size=”14px” button_padding=”12px 18px 12px 18px” border_width=”0px” border_radius=”1px” btn_decoration=”none” text_color=”” default_btn_border=”y” default_btn_border_color=”” default_btn_bg=”y” default_btn_bg_color=”” default_btn_hover=”y” text_hover_color=”” default_btn_border_hover=”y” default_btn_border_hover_color=”” default_btn_bg_hover=”y” bg_hover_color=”” link_font_size=”14px” link_font_style=”:bold:” link_icon_size=”12px” link_padding=”4px 0px 4px 0px” link_text_color=”” link_hover=”n” link_text_hover_color=”” link_decoration=”upwards” link_border_width=”2px” link_border_color=”” icon_picker=”” icon_gap=”8px” icon_align=”left” css=”.vc_custom_1765289587775{margin-top: 40px !important;margin-bottom: 40px !important;}” general_settings=”” normal_settings=”” hover_settings=”” link_general_settings=”” link_normal_settings=”” link_hover_settings=”” link_underline_settings=””][vc_column]
