Visitors to Southern Manufacturing will have an 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 will be 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. The series is also offered in all common imperial dimensions.
For manufacturers investigating the available cutting tools for machining composite materials, the Guhring team will be on hand to demonstrate and discuss some of the latest products from the newly published ‘High Performance Tools for Machining Modern Composite Materials’ brochure. Available to download from the Guhring UK website, the 24-page publication includes the latest solid carbide and PCD drills, as well as end mills, taps, slot drills and PCD compression milling cutters.
The brochure introduces newly developed and extended product ranges that include solid-carbide stub drills and Kevlar drills from 2.5 to 10 mm, the CR100 and FR100 geometry CFRP/GFRP end mills, ISO metric machine taps, and 90 and 120° multi re-grindable PCD drills. Additional products include two, three and four-edge PCD slot drills and end mills with through-coolant.
