It is no longer possible to imagine modern surgery and orthopaedics without implants to stabilise bone fractures or as a replacement for damaged joints. Firstly, they support the healing process and ensure a perfect healing of the bone fracture. Secondly, they replace or restore the mobility and movability of the patient and assist in giving back a high quality of life.

above all, implants are manufactured in stainless steel or titanium-alloy due to the high corrosion resistance and very good biocompatibility - materials that are also valued in other areas such as the areospace industry, energy technology or plant engineering because of their special characteristics.

as a manufacturer of precision tools, Guhring is also one of the leading suppliers in the field of machining stainless steel and titanium-alloy. our research and development centre finds optimally suited tool geometries, our hard material division provides perfectly adapted tool materials and our coating technology provides hard material coatings with the necessary resistance so that the difficult-to-machine materials can be machined with maximum efficiency, highest precision and optimal economic efficiency.

Thanks to the optimised design with unequal helix and 35°/38° helix angles the RF 100 Ti high-performance end mill can be applied for slotting and roughing operations in titanium-alloys and is also suitable for deep cutting depths. Hereby, the unequal helix effectively counteracts vibrations and chattering as well as the so-called corkscrew effect. The optimised corner radius ensures a long tool life together with a high form accuracy.

RaTio end mills RF 100 Va

RF 100 high-performance end mills excell thanks to unequal helix angles considerably reducing vibration. The uneven helix achieves a considerably improved surface for finishing operations and a considerable feed rate increase for slotting and roughing. The complete milling process can be covered with one RF 100 for many applications, generating a considerable cost advantage alongside an increased tool life and dimensional accuracy of the workpiece. Combined with a newly developed roughing geometry RF 100 VA/NF end mills enable drastic tool life increases in comparison to conventional roughing cutters with round and flat knuckle-type teeth. The workpiece surface quality is improved to a peak-to-valley height of approximately Ra = 2-3µm, making in many cases finishing operations unnecessary. At the same time the innovative design reduces power consumption in comparison to conventional RF 100 end mills allowing their use in unstable conditions and in less powerful machines.

highly accurate threads are an absolute must for implants. Guhring taps for this field of application are optimally designed for this task thanks to their special geometry. the coating ensures a long tool life thanks to its resistance to thermal loading and by counteracting the adhesive tendency of the material to be machined. in addition to the taps for metric threads and metric fine threads introduced here, there are also tools for unc and unf threads available in the standard range. as part of our special tool production we also manufacture taps for other thread types.
