#MACH2018 At the
EMO exhibition in 2017, Birmingham-based Guhring Ltd (
www.guhring.co.uk) gave a world premiere to a multitude of new cutting-tool lines; these innovations will receive their UK exhibition premiere at
MACH (Hall 18 Stand 540).
Guhring will present new turning systems. These include: the 104- and 106-series for grooving, boring, broaching and threading; and the 305 system — a ‘three-fold interchangeable indexable insert for external and internal machining’.
In the case of the 104 and 106 systems, visitors will see insert additions with a range of newly added diameters, radii and lengths.
With regard to the 305 series, the exhibition will see the arrival of an entirely new indexable insert with a sintered rake geometry, an increased range of inserts, and new clamping holders for sliding-head lathes.
On the milling front, Guhring will be demonstrating its latest Ratio line of roughing end mills. With flat-crested geometry and an optimised roughing profile that is said to achieve a 60% longer service life, the Ratio end mill has asymmetrical cutting flutes that reduce the cutting pressure compared with smooth cutters.
This soft cutting action allows Ratio cutters to perform well on low-powered machine tools or machines with ‘unstable fixturing’.
Alongside Ratio will be the established RF 100 Diver series of end mills, which has also been enhanced. Optimised internal cooling channels have been introduced, along with a programme expansion for ramp drilling, grooving, rough finishing and finish milling.
The front and peripheral geometries have been updated to enhance lubrication and chip removal efficiency — and give a 40%-longer tool life when machining stainless steel and heat-resistant materials.
MACH will also see the arrival of Pionex, Guhring’s next generation of taps that incorporate a polygon shape claimed to require 30% less torque.
Industry 4.0 will provide a further focal point for Guhring, with the company introducing enhancements to its software-based tool management system, which includes a new Web interface.
