It’s worth regrinding! “Take, for example, the solid carbide deep hole drill RT 100 T from Gühring: This is a deep hole drill with internal cooling and a TiAIN coating. For the example, we have chosen the common dimension with a diameter of 10mm and a diameter-length ratio of 25xD. Depending on wear, the tool can be reground three to five times.”

“Why should you have your tool reconditioned when it reaches the end of its lifetime? There are several reasons for this: On the one hand, we owe it to the environment to use resources sparingly, because the global stocks of raw materials for carbide tools (cobalt and tungsten) are limited. On the other hand, reprocessing also makes sense in terms of economic efficiency,” said Green.

“Our free pick-up and drop-off service even picks up your used tool from you and after seven to 10 working days you will get it back reconditioned. This fast implementation is only possible through short distances.”

The latest Iscar LogiQuick campaign has unveiled a diverse range of new cutting tools, effectively replenishing the company's portfolio.

Alongside these MACH debutants, Guhring will introduce a multitude of favourites such as the RF100 Sharp, the ever-growing Diver Series of end mills and the RF100 Speed. The RF100 Sharp high-performance end mills made a MACH debut appearance in 2022 and will return in 2024 with an extended range to demonstrate how to address the issue of machining soft, tough and high-alloyed materials that create swarf evacuation issues.

Guhring UK will premiere a host of cutting tool innovations at MACH 2024. With new product lines alongside proven ranges there will be a complete range of milling, threading, and drilling solutions on show.

Headquartered in Albstadt, Germany, Gühring has three facilities in this area: the original building where the business began which still manufactures HSS drills and special tooling; a fully functional PCD design and manufacturing facility; and a recently acquired factory in Onstmettingen that is used exclusively for the assembly, service and support of its own range of grinding machines.

“Gühring offers a complete reconditioning service for carbide end mills, including refurbishing of used tools and the addition of corner radius. In addition to standard helix end mill designs, our reconditioning division can also recondition Gühring variable flute and variable helix carbide end mills,” explained Gerald Green, Managing Director of Gühring Cutting Tools South Africa.

MSC Industrial Supply Co. UK (MSC) is celebrating a successful season after sponsoring two local youth football teams during the 2023/2024 campaign.

“The cost of a new tool plus three regrinding of this tool is far below the cost that would be incurred for four new tools in the same period. In this way, you can reduce the cost per tool by more than half with repeated regrinding. The diagram illustrates how tool costs are reduced with each regrind.”

“Our free pick-up and drop-off service even picks up your used tool from you and after seven to 10 working days you will get it back reconditioned. This fast implementation is only possible through short distances.”

The RF100 Sharp Series has an extremely smooth cutting action and high chip removal capability. This, and its ability to be used in a wide variety of applications such as slotting, ramping, roughing, helical milling, finishing and trochoidal cutting, make the new RF100 Sharp and end mill of choice when flexibility is required.

For the micro-machining sector, Guhring will showcase the RF100 Micro Diver. The micro-precision milling range is a universal tool for every material and application. Providing plunging and milling in a single tool, the RF100 Micro Diver is available in two variants, the 6808 and 6809. An innovative flute form further enhances rigidity and eliminates vibration. The series is suitable for cutting materials up to 48 HRC at depths up to 5 x D and is available with a cutting diameter from 0.79mm to 3.175mm.

Upgrades and new equipment investments Continuous improvement, maximum quality and productivity are some of the principles by which Gühring operate. In this regard, Gühring South Africa has invested heavily in making sure it can deliver on these morals. Continued Green: “Recently Gühring South Africa has added a new cylindrical grinder, an energy efficient compressor, as well as a wheel dressing machine capable of dressing single and multiple wheel packs, thus improving efficiency.”

When EuroBLECH, the industry’s flagship trade fair, opens its doors in Hannover from October 22-25, visitors will be able to experience the innovative solutions and full-range strategies that Amada offers its partners.

“It is therefore worthwhile to obtain information about the possibilities of reprocessing the tools when buying new tools. Because the regrinding of tools offers you the following advantages:

The Starrag-Tornos Group recently welcomed guests to its 25th annual ‘Aerospace and Turbine Technology Days’ event hosted by Starrag in Switzerland.

As part of the stand at MACH, Guhring will also be demonstrating its extensive PCD cutting tool portfolio.

The milling portfolio from Guhring continues to expand rapidly. Since MACH 2022, the Birmingham manufacturer has added a wealth of innovations including the new SkyLiner series of end mills for rough and finish machining of aluminium and non-ferrous materials.

Same quality – four times the service life “When it comes to the quality of the final product, there is no difference between the first regrind and the third regrind at Gühring. Our regrinding centres are equipped with the same grinding machines and coating systems as the new production facilities and as a tool manufacturer, Gühring knows all the parameters needed for the regrinding of your tools. This is how the regrinding is done with the original geometries and layers. You will receive a new tool with which you can continue working with the same cutting values and achieve identical results.”

Gühring South Africa first opened its regrind facility in Port Elizabeth, Eastern Cape in late 1999. The 180m² factory served its purposes until a new 873m² factory was built in 2010 in the Greenbushes area of Port Elizabeth and the company moved to these facilities.

Especially suited for pocketing and wall applications with thin wall sections with depths up to 3 x D, the new Alu RF100 SkyLiner F delivers excellent surface finishes even at the highest feed rates.

Gottlieb Gühring started the company with 17 employees manufacturing a small range of twist drills, spirit levels, screw clamps, fastening chains and plumb bobs. In 1964, the current owner and Gottlieb’s grandson, Dr Jörg Gühring joined the company. Today, Oliver Gühring represents the fourth generation of the family, sitting alongside his father as part of a four-man executive board and taking responsibility for sales and marketing activities.

The new RT100 InoxPro overcomes these challenges with its new geometry that optimises chip formation. This combined with an ultra-smooth Perrox coating enhances wear protection and an optimised carbide substrate that delivers the perfect balance of hardness and toughness.

The latest Iscar LogiQuick campaign has unveiled a diverse range of new cutting tools, effectively replenishing the company's portfolio.

The HyproJET X6 from Ceratizit is based on an improved and patented design which makes is possible to increase cutting performance, leading and lifetime.

“And when your tool is finally worn out, we will even buy back the carbide from you – to recycle it,” concluded Green.

Available with 3 x D, 5 x D and 7 x D variants from 3 to 20mm diameter with 0.1mm increments, Guhring says this through coolant series will improve feed rates and tool life by more than 50% while improving process control and chip evacuation. The company will also present its Micro Precision Drills, the RT100T and RT100XF as well as firm favourites like the HR500 reaming line and SpyroTec spiral fluted chamfer milling cutters.

Fourth generation Founded in 1898, Gühring has successfully evolved to take the place as one of the leading manufacturers and suppliers of rotary cutting tools.

“Investing in a new tool every time you notice wear is expensive – and also unnecessary for many solid carbide tools. Because the quality of the tool core and the cutting material has not changed. Only the cutting edges need to be sharpened. The cost of such regrinding represents only a fraction of the purchase price for a new tool.”

Please contact Gühring directly for reconditioning inquiries for non-Gühring manufactured variable flute designs.

This three-flute tool is offered in diameters from 6 to 20mm with axial through coolant ducts, a 0.2mm corner radius and a variable helix that makes the range perfect for finish milling. Accompanying the Alu RF100 Skyliner F at MACH will be the Alu RF100 SkyLiner R for rough machining. Guhring says this series is the perfect solution for high-performance machining in aluminium.

In addition, a nearby complex in Sigmaringen-Laiz is home to four vital aspects of Gühring’s business: R&D, OEM support, the manufacture of carbide tools and taps and apprentice training. In its tap and threadmill manufacturing plant alone, 60 000 taps are manufactured from start to finish every week.

As well as demonstrating all the latest ranges, 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 its facility in Birmingham. Guhring UK has a team of expert engineers that can create productivity, cost, inventory and cycle time savings for UK manufacturers.

62% cost savings by regrinding your tools “Used tools like new again – this is what we offer you through our regrinding service. In our regrinding centre, we restore the original geometries and layers of the worn tools and thus also their original performance. This allows you to reuse tools instead of replacing them and reduce your total cost of ownership: For some Gühring tools, the cost savings due to regrinding are up to 62 per cent!”

Notably, Guhring will give a MACH show premiere to the new RT100 InoxPro range of high-performance solid carbide drills for machining stainless steel and titanium alloys. When machining these challenging materials, tool wear can be a formidable opponent to productivity and performance.

Gühring has a presence now in most countries throughout the world. There are 46 sales companies globally, 31 production plants and 47 service centres and the tooling range has grown significantly comprising some 1 850 tool types, including 45 000 standard tools.
