4000 instead of 40 <\/span>
\nUnbeatable tool life with the high-performance reamer<\/span><\/h1>\n

Perfect dimensional accuracy, reduced machining times and a 100-fold increase in tool lives \u2013 KIPP is achieving all this with the high-performance HR 500 reamer from G\u00fchring. The family-run company from Sulz am Neckar in Germany was facing a challenge when it came to producing precise fits: \u00b5-level precision when machining difficult materials such as cast steel places high demands on the tools used to produce the exact through-holes. With the HR 500, KIPP no longer has to worry about poor dimensional accuracy or short tool lives.[\/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” locked=”off” global_colors_info=”{}”][et_pb_column type=”3_4″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/guehring.com\/wp-content\/uploads\/2025\/09\/GUE_blog-kipp-success-story.jpg” alt=”Beratungssituation zwischen zwei Personen in der Produktion” title_text=”Beratungssituation zwischen zwei Personen in der Produktion” _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=”4.21.0″ _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=”4.23.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

Clamping technology, standard elements and operating components \u2013 these are the specialities of HEINRICH KIPP WERK GmbH & Co. KG<\/a>. The family-run company, which made its name with the classic KIPP clamping lever, employs 500 people and manufactures standard parts and assemblies for the areas of industry, mechanical engineering and plant construction. Its exceptionally high standards of ergonomics, stability and precision always come first. This also applies to its production of precise fits in cast steel, which pushes conventional reamers to their limits \u2013 and poses real challenges for KIPP.<\/p>\n

The grip is a small cast-steel product that, after production, is assembled to create a complete device, known as the cam-action indexing plunger. This can be used to lock and unlock machine doors manually, for example. After the grip has been inserted into a threaded sleeve with a spring assembly, a bolt is pressed into the grip\u2019s fit.<\/p>\n

There is no room for large tolerances: As it is a press fit, the hole must be perfectly matched to the bolt. For the H7 fit with a tolerance range of + 5\u00b5, it first has to be pre-drilled and then machined with a reamer. A 3-axis STAMA milling machine is used for this purpose.<\/p>\n

[\/et_pb_text][\/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=”4.23.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

However, it is all easier said than done: Two different materials are used to manufacture the products, which does not make things easy for the reamers: Stainless steel 1.4308 and quenched and tempered steel C 45. \u201cWhen it comes to dimensional accuracy in particular, cast materials are always somewhat problematic because the exact composition of the alloy can vary,\u201d explains Alexander Wolber, who is responsible for tool coordination at KIPP. \u201cThe materials have hard and tough properties, which makes them difficult to machine.\u201d<\/p>\n

And KIPP is all too familiar with these difficulties: \u201cFirst we used HSS reamers for the grip\u2019s fit, but that didn\u2019t work out at all,\u201d recalls Alexander Wolber. But even a competitor\u2019s solid carbide reamers delivered results that were far from satisfactory. The tools reached the end of their tool life after a maximum of 20\u201340 components.<\/p>\n

In some cases, we experienced built-up edges, while in others, the tools even broke off,\u201d recalls Wolber. \u201cDue to the rapid rate of wear, it was almost impossible for us to maintain the required dimensional accuracy.\u201d These difficulties were topped off by high tool costs, because KIPP not only produces grips in four different sizes, but also in high quantities: Even with a tool life of 40 components, KIPP would need 1,500 reamers to produce the 60,000 grips that need to be produced each year. It was clear that a different tool solution had to be found.[\/et_pb_text][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ module_id=”2″ _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][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=”4.23.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

A G\u00fchring high-performance reamer has the answer<\/h2>\n

\u201cThere are no problems, only challenges,\u201d says J\u00fcrgen Knorr, sales representative at G\u00fchring. When Alexander Wolber presented the situation to his contact at G\u00fchring, it didn\u2019t take long for a solution to be found: \u201cThe HR 500 offers a decisive competitive advantage: our tool lives are now multiple times longer and we can move much faster,\u201d explains J\u00fcrgen Knorr. \u201cTo put it simply: the HR 500 does its job.\u201d\n<\/p>\n

This means that steels, stainless steels, special alloys and hardened steels up to 63 HRC can be machined easily and precisely. As such, this version is suitable for both materials that KIPP uses for its grips. But what advantages does this reamer offer compared to conventional solid carbide reamers? The answer lies in the perfect combination of geometry, coating and cooling. The extremely unequal blade pitch ensures a smooth cut and high surface quality, while the central coolant supply with front-side outlets ensures good chip removal in the blind hole.

The TiAIN nanoA coating protects the tool from wear and ensures long tool lives. Thanks to these properties, the HR 500 impresses compared to conventional solid carbide reamers with extreme levels of performance. Shortly afterwards, KIPP began its initial trials with the high-performance reamer from G\u00fchring.<\/p>\n

The courage to push ahead pays off<\/h2>\n

\u201cOur first attempts were relatively unsuccessful because we approached the new tool with low feed rates,\u201d smiles Wolber. \u201cWe weren\u2019t used to reamers working with these high feed rates.\u201d A reasonably common occurrence as J\u00fcrgen Knorr well knows: \u201cThe HR 500 facilitates significantly higher feed rates. This scares off lots of customers at first, because they tend to work with slow feeds when reaming.\u201d And for good reason: Feed rates that are too high during reaming can result in poor surface finishes, tool breakage or even damage to the machine. Thanks to the HR 500, KIPP doesn\u2019t have to worry about this.<\/p>\n

However, the courage to push ahead pays off: \u201cWe were not only able to achieve excellent dimensional accuracy, but we are also able to machine much faster,\u201d reports Alexander Wolber enthusiastically. Compared to the competitor\u2019s reamers, KIPP can produce the fit at a feed rate of 0.6 mm\/rev instead of 0.125 mm\/rev. And the HR 500 is also an absolute game changer when it comes to tool lives: \u201cWe used to be able to produce 20\u201340 grips per reamer. The HR 500 can handle up to 4,000 grips without any detriment to the dimensional accuracy,\u201d says Wolber.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.23.4″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n\n\n\n\n\n\n\n

Overcoming challenges together<\/h2>\n

By switching to the high-performance reamer from G\u00fchring, KIPP is not only reducing its machining time, but also saving on tool costs \u2013 and does not have to worry when it comes to meeting the tight tolerances.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”3_5,2_5″ module_class=”gue-row-vertical-aligned-content gue-row-2col-image-text” _builder_version=”4.21.0″ _module_preset=”default” locked=”off” global_colors_info=”{}”][et_pb_column type=”3_5″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/guehring.com\/wp-content\/uploads\/2025\/09\/GUE_kipp-menschen.jpg” alt=”Beratungssituation in der Produktion” title_text=”Beratungssituation in der Produktion” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”2_5″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n

KIPP is now using a number of different G\u00fchring reamers. In addition to the HR 500 range, these also include special tools that are specifically tailored to the customer\u2019s requirements. One thing that KIPP particularly appreciates about working with G\u00fchring is having a fixed, reliable contact person who is not afraid of challenges: \u201cJ\u00fcrgen Knorr is always ready to lend us his ear.
