Guhring (
www.guehring.de) (Hall 25, Stand B60), which has a UK subsidiary in Tamworth, will be demonstrating a complete range of extended and new tooling lines aimed at optimising productivity and performance. In the case of the company’s 104 and 106 boring systems, visitors will see a range of new diameters, radii and lengths; while for its 305 series of turning tools, Guhring will present a new indexable insert with sintered rake geometry, an increased range of inserts and new clamping holders for sliding-head lathes. From a milling perspective, the company will be demonstrating its new Ratio line of roughing end mills. These feature a flat-crested geometry and an optimised roughing profile that is said to achieve a 60% longer service life.
Moreover, Ratio’s asymmetrical cutting flutes increase material removal rates and reduce cutting pressure compared with ‘smooth’ cutters. This soft cutting action allows the end mills to perform well on low-power machine tools or machines with unstable fixture set-ups.
Alongside Ratio will be the enhanced RF100 Diver series of end mills, which now feature optimised internal cooling channels and a ‘programme expansion’ for ramp drilling, grooving, rough finishing and finish milling. The RF100 Diver has been designed for customers with constantly changing requirements, and the one tool can be used for five types of operation.
Several updates have been applied to the latest variants: for example, the front and peripheral geometry designs have been updated through FEM optimisation to enhance lubrication and chip-removal efficiency — an upgrade that is said to give 40% longer tool life on sticky materials, stainless steel and heat-resistant alloys.
EMO will also mark the introduction of Pionex, Guhring’s next generation of taps. These incorporate a new polygon shape that requires 30% less torque, and they feature a newly developed material that has a higher wear-resistance than previous generations of taps. The tools also feature a TiCN coating for longer tool life — and significantly improved lubrication grooves.
Industry 4.0 will also be a key focus for Guhring at EMO; the company will be introducing enhancements to its software-based tool management system.
