Birmingham-based Guhring Ltd, (
www.guhring.co.uk), a cutting-tool manufacturer, will be giving exhibition premieres at
Southern Manufacturing 2020 to its high-performance line of end mills and the latest addition to its extensive hole-making portfolio (Stand H185).
Visitors will get to see first-hand the new Guhring RF Speed milling range, developed for the machining of very tough materials. The latest arrivals — the new RF100 5-Speed and RF100 7-Speed solid-carbide end mills — are said to take
‘cutting speeds and process reliability to a new level’.
The increased tooth number of the five-fluted 5-Speed and seven-fluted 7-Speed generate high metal removal rates with stable process reliability, even when processing the most difficult-to-machine materials.
Providing high-performance roughing at high cutting depths, the two new ranges maximise feed rate parameters during large-scale metal removal.
As part of the highly dynamic Guhring Trochoidal Cutting (GTC) series, the new end mills are suitable for machining tough stainless steels, special alloys and a wide variety of steel and cast-iron grades.
Alongside the RF Speed milling line will be the new RT100XF — the latest in a long line of high-performance drilling products from Guhring.
Branded as ‘extreme and powerful’, this has been developed to generate ‘outstanding feed rates and exceptional metal removal rates’.
Created to reduce cycle times for difficult-to-machine materials and special applications in series production, the extremely hard new drilling line is said to be extremely resilient to potential breakages.
This claim is based on the new carbide grade developed by Guhring for the RT100XF, which performs a ‘balancing act’ between hardness and toughness.
The design and geometry of the new RT100XF support the robust performance of the carbide grade and surface treatment with an early double-margin support that perfects the coaxiality to ensure the specified bore size and roundness.
This makes the RT100XF the drill of choice for precision, concentricity and performance for hole making from 5xD upwards.
Available in 5xD and 7xD, the new drills can be purchased in diameters from 3 to 20mm with 0.1mm increments. The series is also offered with 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 new products from the newly published High Performance Tools for Machining Modern Composite Materials brochure.
Available to download from the Guhring UK Web site, this 24-page publication includes the latest solid-carbide and PCD drills and end mills, taps, slot drills and PCD compression milling cutters.
It also introduces new and extended product ranges that include solid-carbide stub drills and Kevlar drills from 2.5
to 10mm, the CR100 and FR100 geometry CFRP/GFRP end mills, ISO metric machine taps and 90 and 120deg multi-regrindable PCD drills.
