When it comes to holemaking, Guhring is undoubtedly a world-leading manufacturer – and at MACH 2022, show visitors will be able to see exactly why. At the Birmingham NEC in Hall 19 on Stand 210 from the 4th to the 8th of April, the cutting tool manufacturer will be demonstrating a host of new and existing technology with demonstrations on a Grob G550 5-axis machining centre.
At MACH, Guhring will showcase a complete range of threading, turning, drilling and milling tools, with many of its industry-leading drilling lines undertaking ‘live cutting’ demonstrations. One of the leading products that will be showcased on the Grob G550 will be the RT 100T solid carbide spiral flute deep-hole drills. The program for the RT 100T drills includes standard drills for drilling depths up to 15XD, 20XD, 25XD, 30XD and 40XD with diameters available from 3 to 14mm with an exceptional range of diameter increments. The RT 100T demonstrates an outstanding cost-performance ratio whilst permitting the highest cutting and feed rates – something that MACH visitors can witness with the live demonstrations. The spiral-flute deep hole drills possess a special flute geometry that is optimised for evacuating chips from deep holes. This is complemented by a coolant duct profile that maximises flow to the cutting edge and supports chip removal.
Complementing the RT 100T on the Grob G550 5-axis machining centre will be the RT100XF drilling series. Providing unbridled power and outstanding results, the holemaking benchmark will be highlighting its incredible speed and productivity with a live demonstration at MACH. Branded as ‘Extreme and Powerful’, the RT100XF has been developed with all tool parameters optimised to generate outstanding feed rates and 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 resilient to potential breakages.
With a new carbide grade developed for the RT100XF that performs a balancing act between hardness and toughness, the special structure of this carbide grade has a re-sharpening effect, so breakages that normally accelerate tool wear, no longer occur. This is supplemented by the nanoFire coating system created by a specially designed pre-and post-treatment that smooths the coating and makes it more robust.
The design and geometry incorporate early double margin support that perfects the coaxiality to ensure perfect bore size and roundness. This makes the RT100XF the drill of choice for precision, concentricity and performance hole making from 5XD upwards. The through coolant drills are perfect for the drilling of structural and case-hardened steels, free-cutting and heat-treated steels, nimonics, titanium, inconel and hastalloy, making the RT100XF ideal for any machine shop. The drills are available in 5XD and 7XD with diameters from 3mm to 20mm with 0.1mm increments.
Complementing the drilling lines, there will be a live demonstration of the HR500 solid carbide universal reaming line. The HPC reaming line operates at the highest possible cutting rates with the result being holes of the utmost in precision, concentricity and surface finishes. The HPC line is suitable for finishing holes on a vast array of materials that include steels, aluminium alloys, cast materials, plastics, magnesium alloys, copper, brass and much more.
Guhring will also have a 12mm diameter SpyroTec chamfermill on the Grob machine. The SpyroTec 5-fluted spiral fluted chamfer milling cutter is available with a 60, 90 or 120 degree and on the Grob machine at MACH, the 12mm diameter variant with a 90 degree angle will be in action. With five different spiral angles and an uneven cutting edge, the SpyroTec that is available from 6 to 20mm diameter reduces vibration and improves surface finishes. To further enhance surface finishes and provide a smooth cutting action, the SpyroTec chamfermill incorporates a positive rake angle geometry with face cutting that enables the customer to use the full cutting edge length of the tool. Manufactured from the finest grain carbide with a TiAlN coating, the SpyroTec prolongs tool life and enhances performance for the end-user.
As well as demonstrating an extensive range of innovative solid carbide tooling solutions, Guhring engineers will be at MACH to discuss the scope of special tooling solutions that can be designed, developed, manufactured and trialled at the Guhring facility in Birmingham. Guhring UK has a team of experts that can create productivity, cost, inventory and cycle time savings for UK manufacturers.
