At last week’s Southern Manufacturing 2019 exhibition, cutting-tool manufacturer Guhring gave exhibition premieres to a number of recently introduced products. For instance, the company showcased its high-performance line of end mills and the latest addition to its hole-making portfolio.
Notably, visitors had the opportunity to investigate the latest Guhring RF Speed milling range that has been developed for the machining of tough materials. The latest arrivals are the RF100 5-Speed and RF100 7-Speed solid-carbide end mills.
The increased tooth number of the five-fluted 5-Speed and seven-fluted 7-Speed generates high metal removal rates with stable process reliability, even when processing difficult-to-machine materials, says Guhring. Providing high-performance roughing at high cutting depths, the two ranges are said to maximise feed-rate parameters when applying large metal removal rates. As part of the Guhring Trochoidal Cutting (GTC) series, the RF100 5-Speed and RF100 7-Speed are suitable for machining tough stainless steels, special alloys and a variety of steel and cast-iron grades.
Alongside the RF Speed milling series was the RT100XF, the latest in a long line of performance drilling products from Guhring. Created to reduce cycle times for difficult-to-machine materials and special applications in series production, the hard drilling line is said to be resilient to potential breakages. This claim is based upon a newly developed carbide grade developed by Guhring that performs a balancing act between hardness and toughness.
The design and geometry of the RT100XF supports the robust performance of the carbide grade and surface treatment with an early double-margin support that aids coaxiality to ensure bore size and roundness are achieved. Available in 5xD and 7xD, the drills can be purchased in diameters from 3 to 20 mm diameter, in 0.1 mm increments.
