Secure and high-quality aluminium threading with nextgeneration CoroTap ® 100 and CoroTap ® 400
Global metal cutting specialist Sandvik Coromant introduces a new generation of CoroTap ® 100 and CoroTap ® 400 for short-chipping and chip-free tapping of aluminium . The taps offer high process security and predictable tool life .
Threading is often the last operation in your component , and the last thing you want is for the tap to break . That is why process security and predictable tool life are of the highest importance when it comes to tapping . The next-generation CoroTap ® 100 and CoroTap ® 400 , with optimized performance in aluminium , can meet very strict process security demands and offer a high level of reliability and consistent tool life .
The CoroTap ® 100 straight flute tap features a refined edge rounding that helps to remove burrs and improve surface finish . The combination of core thickness , rake / relief angles and land width gives an optimal flute geometry with great chip evacuation . If threading deep holes , the back chamfer helps to improve the threading capacity .
The CoroTap ® 400 forming tap has an optimized lobe shape developed for aluminium machining and a low frictioncoefficient surface treatment for a smooth and polished thread surface finish . With a reduced thread length , the tap is less in contact with the material , reducing power consumption and torque . Finally , staggered coolant holes offer excellent coolant flow into the thread-forming zone and a safe forming process .
In a production process , tapping can be a bottleneck and increased productivity is often a demand . For example , a typical aluminium cylinder block can have up to 12 different threads in its structure and tapping is the most time-consuming process . With the new straight flute tap and forming tap , you can increase productivity and reduce cost per part . “ Both geometries are combined with the latest surface treatments , substrates
The CoroTap ® 100 straight flute tap features a refined edge rounding that helps to remove burrs and improve surface finish . and coatings , which gives the ability to use higher cutting data with significantly improved tool life , resulting in lowering your cost per part .” says Robert Smith , Offer Manager for Hole Making and Composites at Sandvik Coromant .
Both taps can be used for blind and through holes in many different components , such as cylinder blocks , cylinder heads , electric motor housings , transmission housings and battery racks . Robert continues : “ These products are beneficial for anyone who machines aluminium , including automotive , E-mobility and general engineering .”
