Guhring will return to the MACH exhibition with new product lines alongside established ranges.

The company’s stand will showcase a complete range of the cutting tool manufacturer’s threading, turning, drilling and milling tools, many of which will be live cutting at the exhibition on a Grob 5-axis machining centre on the Guhring stand.

From its extensive milling portfolio, Guhring will be giving a show debut to the new RF100 Sharp Series of high-performance end mills – and this range will be put through its paces on the Grob. Designed to address the issue of machining soft, tough and high-alloyed materials that create an issue with swarf clearance, the new RF100 Sharp Series is Guhring’s sharpest solid carbide milling tool to date.

The RF100 Sharp end mills offer an extremely smooth cutting action and effective chip removal – ideal for slotting, ramping, roughing, helical milling, finishing and trochoidal cutting. The smooth cutting action combined with the potential to be used in a wide variety of applications makes the new range of end mills a high performing choice on challenging materials.

With four flutes, the tools are suitable for machining steel, stainless steel, aluminium, aluminium alloys and other difficult materials and are available in a number of options: an extra-long design long (DIN+) that is an extension on the long (DIN) version but with an even longer cutting edge, and also a standard length end mill.

The RF100 Sharp is offered in all common sizes up to 20mm diameter and depending upon the chosen diameter, this range is supplied with an overall length from 50 to 104mm with a flute length from 3 to 41mm.

Following the success of its Diver Series of end mills, Guhring has now extended the benefits of this series to the micro-machining sector with the new RF100 Micro Diver. The new micro-precision milling range is a universal tool for every material and application.

Providing plunging and milling in a single tool, the RF100 offers extreme cutting values with high cutting depths. Available in two variants, the 6808 and 6809, the tools feature a symmetrical drilling face for stability when ramping and drilling, a new transition geometry to improve rigidity and an innovative flute form that further enhances rigidity and eliminates vibration.

The RF100 Micro Diver series is suitable for cutting materials up to 48HRC at depths up to 5 X D. With a 40° helix angle to evacuate chips from the work area when conducting high-speed machining, the series is available with a cutting diameter from 0.79mm to 3.175mm with a multitude of dimensional increments available.

 

Appearing alongside the new ranges will be established lines like the RF100 5-Speed and RF100 7-Speed solid carbide end mills – developed for the machining of very tough materials

The increased tooth numbers on 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. As part of the highly dynamic Guhring Trochoidal Cutting (GTC) series, the new endmills are ideal for machining tough stainless steels, special alloys and a wide variety of steel and cast-iron grades.

The optimal cutting conditions for the 5-Speed is applications on all tough materials up to 1200N/mm² and where a ramping angle of up to 10° is required. The tool is also ideal for slotting with cutting depths up to 1 x D and helical milling. Whilst the RF 100 7-Speed is also a sound choice for tough materials up to 1,400N/mm², the seven fluted variant is also ideal for helical milling at in-feeds of up to 0.05 x D ap per cycle.

From a dimensional perspective, the new tools are available with cutting diameters of 6, 8, 10, 12, 16 and 20mm with a necked diameter that permits cutting depths from 20 to over 60mm depending upon the diameter selected.

Also, on show at MACH will be the Ratio line of roughing end mills. With flat crested geometry and an optimised roughing profile that demonstrates 60% longer service life, the Ratio high-performance roughing cutter has several geometry adjustments aimed at enhancing performance. The roughing end mill increases material removal rates with its asymmetrical cutting flutes that reduce cutting pressure compared to smooth cutters.

As well as demonstrating an extensive range of innovative solid carbide tooling solutions, Guhring engineers will be on hand at MACH to discuss the scope of special tooling solutions that can be designed, developed, manufactured and trialled at the Guhring facility in Birmingham.

Also on the stand, Guhring will also be demonstrating its PCD cutting tool portfolio which includes two, three and four cutting edge PCD slot drills and end mills with through-coolant, all available with a wide variety of shank forms and tolerances, surface finishes and coatings, helix and rake angles and cutting edges.
