Deep drilling in cast iron <\/span>
\nHow to double your speed in cast iron machining<\/span><\/h1>\n

G\u00fchring has developed a new tool technology that can produce drilling depths of up to 40xD. This technology can work up to twice as fast compared with conventional methods \u2013 even when drilling deep holes, reducing the cycle time considerably, sometimes by several minutes, significantly increases capacity.<\/p>\n

Moving masses on this scale requires immense power under the bonnet \u2013 which can only be provided by large engines<\/a>.<\/p>\n

But manufacturing them poses challenges for companies, as deep holes have to be drilled into the drive components made of different types of cast iron. Creating these holes in the conventional way is time consuming and expensive.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”2_5,3_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=”2_5″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/guehring.com\/wp-content\/uploads\/2024\/06\/Motor.jpg” alt=”Zeichnung eines Motors” title_text=”Zeichnung eines Motors” _builder_version=”4.27.4″ _module_preset=”default” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”3_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

A new tool solution is required, with an adapted geometry and inherent stability that absorbs the forces during machining and keeps them as low as possible.<\/p>\n

The crux of the matter: The machine related limits of axial force and torque are limited on many machines. The drilling quality and tool life must also remain the same as with conventional methods. Working in partnership with a customer, G\u00fchring developed a new power technology: The four-fluted deep hole drill VB80 and the four-fluted drill VB100 are used to drill holes, pilot holes and stepped holes.<\/p>\n

These tools are specially designed for castings. Their performance is based on the carbide made by G\u00fchring from ultra-fine grains and the proven Signum coating. \u201cThis has proven to be the strongest layer for castings,\u201d explains Philipp Kunze, developer in the field of deep hole drilling at G\u00fchring. To cope with the high chip volume, G\u00fchring uses its patented 2+4 cutting edge division. The main load of the massively increased feed per revolution is initially absorbed by the two inner cutting edges. These are supported by a thick core and a specially defined cutting wedge static. The special grinding for producing the transverse cutting edge ensures low forces. The four \u201cperipheral cutting edges\u201d are then used to absorb the high torque. Typical casting wear is divided over four instead of two cutting edges. The corner radii complete the system by creating the finest surface finishes. The result: shorter chips, higher cutting parameters and a significant increase in process reliability.<\/p>\n

The VB80 deep hole drill has a solid base body made of solid material with straight flutes onto which a solid carbide head is brazed in a form-fitting way. Despite the faster processing, the tool life remains the same or can even be significantly improved.<\/p>\n

For example, in the material GG25, both types of drill can achieve tool life of up to 250 m under optimum conditions. Once the tools have reached tool life, they can be reground 5 to 10 times due to low wear.<\/p>\n

Surface and diameter tolerances impress with their exceptional precision<\/h2>\n

With regard to possible roundness, values of less than 10 \u03bcm have already been achieved with the four-flute drills. With diameter tolerances zones of up to IT7, the tool also outperforms established quality values, and surface values in the roughness class N8, sometimes even N7, can be achieved in different cast types.<\/p>\n

Thanks to the optimised cutting edge formation and the inherent stability of the drills, very low runouts are generated. In combination with a VB100 as a pilot drill, the VB80 deep hole drill achieves comparable or even better results in terms of the runouts despite the high feed rates compared to established processes.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_3,1_3,1_3″ module_class=”gue-row-vertical-aligned-content gue-row-2col-image-text” _builder_version=”4.27.4″ _module_preset=”default” locked=”off” global_colors_info=”{}”][et_pb_column type=”1_3″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/guehring.com\/wp-content\/uploads\/2024\/06\/TLB_303540868_D1370-980×748-1-300×229-1.jpg” alt=”Spitzengeometrie ohne Spanbrecher” title_text=”Spitzengeometrie ohne Spanbrecher” _builder_version=”4.27.4″ _module_preset=”default” max_height=”400px” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/guehring.com\/wp-content\/uploads\/2024\/06\/303540868_4S_D137-980×748-1-300×229-1.jpg” alt=”Spitzengeometrie mit Spanbrecher” title_text=”Spitzengeometrie mit Spanbrecher” _builder_version=”4.27.4″ _module_preset=”default” max_height=”400px” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.21.0″ _module_preset=”default” global_colors_info=”{}”][et_pb_image src=”https:\/\/guehring.com\/wp-content\/uploads\/2024\/06\/Bohrer_Freisteller-1.png” alt=”VB80 und VB100″ title_text=”VB80 und VB100″ _builder_version=”4.27.4″ _module_preset=”default” max_height=”400px” global_colors_info=”{}”][\/et_pb_image][\/et_pb_column][\/et_pb_row][\/et_pb_section][et_pb_section fb_built=”1″ _builder_version=”4.23.1″ _module_preset=”default” saved_tabs=”all” locked=”off” global_colors_info=”{}”][et_pb_row module_class=”gue-row-text” _builder_version=”4.23.1″ _module_preset=”default” global_colors_info=”{}”][et_pb_column type=”4_4″ _builder_version=”4.23.1″ _module_preset=”default” global_colors_info=”{}”][et_pb_text _builder_version=”4.27.6″ _module_preset=”default” global_colors_info=”{}”]<\/p>\n
