Universal & unbeatable <\/span>
\nDouble tool life with the HR 500 high-performance reamer Select<\/span><\/h1>\n

Best hole qualities, tight tolerances, maximum precision: these are the key factors in the manufacture of mould inserts made of hardened steel. Fritz Schmidt Metallgie\u00dferei GmbH & Co. KG relies on high-performance reamers from G\u00fchring\u2019s HR 500 range. This enables the Meckenheim-based company to double its tool life compared to a competitor\u2019s reamers. And thanks to cutting speeds that are five times higher, it also saves valuable machining time.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”3_4,1_4″ module_class=”gue-page-header” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”3_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/guehring.com\/wp-content\/uploads\/2025\/09\/GUE_success-story-fritz-schmid_blog-header-1.jpg” alt=”Hochleistungsreibahle von G\u00fchring, daneben zwei Zerspaner mit Pl\u00e4nen” title_text=”Hochleistungsreibahle von G\u00fchring, daneben zwei Zerspaner mit Pl\u00e4nen” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_4″ _builder_version=”4.16″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_column][\/et_pb_row][et_pb_row module_class=”gue-row-text” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

Customers from various industries, such as medical technology and the automotive industry, rely on the high level of vertical integration at Fritz Schmidt Metallgie\u00dferei GmbH & Co. KG: Thanks to its in-house design, foundry, mould making and mechanical processing, the company offers tailor-made solutions in the field of aluminium die casting as well as for mould and plant engineering. The highest quality standards are a top priority.<\/p>\n

\u201cWe have been using various G\u00fchring tools for years,\u201d reports Fabian Hambach, deputy manager of toolmaking at Fritz Schmidt Metallgie\u00dferei GmbH & Co. KG: \u201cIn the last four years, we have significantly increased the number of G\u00fchring tools, particularly in mould making.\u201d This is an area where not only precision and process reliability are extremely important. Tight tolerances must also be adhered to in order to maintain the required contour accuracy. This is particularly true in the area of reaming, where manufacturing must be accurate to the micron.<\/p>\n

Precision without compromise<\/h2>\n

Reamers are also used in the production of mould inserts manufactured by the company. Extreme precision is required here, as these moulds define the outer contour and surface of the component produced in the die-casting process. This process enables the mass production of complex components made of aluminium alloys, which are used in the automotive industry, for example. The quality of many components therefore depends on the quality of a mould insert \u2013 Fritz Schmidt Metallgie\u00dferei GmbH & Co. KG has no room for compromise.<\/p>\n

A mould insert is manufactured from hardened steel<\/p>\n

To drill holes of different diameters in the mould inserts, Fritz Schmidt Metallgie\u00dferei GmbH & Co. KG initially uses reamers from a competitor. However, the results are not entirely satisfactory: the service life is insufficient, resulting in high tool costs. Fabian Hambach then asks his long-standing contact at G\u00fchring for advice: \u201cWe can do better than that,\u201d says sales representative Marcel Horn \u2013 and recommends a high-performance reamer from the HR 500 range to his customer. \u201cThe HR 500 is one of the G\u00fchring tools I would stake my reputation on,\u201d says Marcel Horn. And soon the customer would share this opinion.<\/p>\n

Maximum performance in hardened steel<\/h2>\n

\u201cSince we were looking for a reamer for these applications that also performs very well in hardened steel up to 50 HRC, the decision was quickly made in favour of the HR 500 Universal for through holes (item no.: 1686),\u201d explains Marcel Horn. In addition to outstanding hole qualities and process reliability, the reamers also have to cope with very hard and wear-resistant material. Since liquid aluminium alloy is later injected into the mould under high pressure, the mould insert is exposed to high mechanical stresses and temperatures \u2013 and must not deform. For this reason, the company uses hardened steel (1.2399, 48-50 HCR), which can withstand these stresses.<\/p>\n

Forging plans together: Fabian Hambach (Fritz Schmidt Metallgie\u00dferei GmbH & Co. KG) and Marcel Horn (G\u00fchring)<\/p>\n

A case for the HR 500 Universal: the high-performance solid carbide reamer not only demonstrates its strengths in steel, stainless steel, titanium and special alloys, but also in hardened steels up to 63 HRC. The TiAIN-nanoA coating ensures high wear protection, which in turn leads to long tool life. It is available in diameters ranging from 2 mm to 20 mm. During machining, the central coolant supply with outlet via oil grooves on the shank ensures optimum cooling and reliable chip removal in the through hole. In combination with the extreme feed and cutting speeds that can be achieved with the HR 500, users do not have to worry about process reliability.<\/p>\n

Double service life, 5-fold faster cutting speeds<\/h2>\n

\u201cWe tried out the reamer and immediately achieved excellent results,\u201d recalls Fabian Hambach. The high-performance reamer (\u00d8 10 mm) can machine 230 holes in mould inserts for the automotive industry, where the reamer previously used had reached the end of its service life after only 115 holes. But that\u2019s not all: \u201cOur original goal was to increase service life and process reliability,\u201d reflects Fabian Hambach. \u201cThe fact that we have also become many times faster was a positive side effect.\u201d<\/p>\n

Instead of the previous cutting speed of V(c)= 10 m\/min, the HR 500 easily achieves five times that speed: \u201cThe competitor\u2019s tool couldn\u2019t even come close to our cutting values,\u201d summarises Marcel Horn. Thanks to the switch to high-performance reamers from the HR 500 range, Fritz Schmidt Metallgie\u00dferei GmbH & Co. KG has been able to significantly improve service life and machining times while maintaining the same surface quality and tolerances.<\/p>\n

No more gaps<\/h2>\n

With the HR 500 range, G\u00fchring offers standard high-performance reamers for all diameters from 1.95 mm to 76 mm. Customers benefit from short delivery times and a wide product portfolio: in addition to the version for universal applications, the standard range also includes the short HR 500 version for limited installation spaces and various material specialists, such as for applications in cast iron or aluminium.<\/p>\n

While standard fixed dimensions are only available in a range of +\/- 0.03 and in 10\u00b5 increments, G\u00fchring is closing a significant market gap with this new addition: the Albstadt-based tool manufacturer is now also offering the fixed dimension series in a range of +\/- 0.05 and in 5\u00b5 increments. This saves users high costs for special tools and also benefits them with over 100% more wear allowance and longer tool life.<\/p>\n
