Even the most wear-resistant tool will show signs of wear when subjected to extreme machining demands. The professional regrinding and recoating with original geometries and coatings by Guhring reproduces the original efficiency so that the tools continue to optimally satisfy all quality parameters. In addition, the refurbishment increases the tool life, considerably less resources have to be allocated for new tools.

This high-tech improvement is also available for non-Guhring products. With Guhring‘s de-coating, regrinding and recoating service you can keep your tool stock to a minimum.

Guhring offers a complete program of modern tool management, tailormade to specific customer requirements. We have developed three different modules that are available in any desired combination.

The first concept incorporates the optimisation of the customer's tool management. This includes, for example, reducing the number of suppliers or outsourcing individual tool management elements such as re-grinding or coating.

The second concept can be characterised as a tool management influenced by logistics. Above all, it involves easing your tooling logistics, by, for example, installing the TM vending machine.

The third concept is termed as technological tool management. It includes technical advice, optimising the operating processes and reducing the tooling costs per produced workpiece up to supplying an entire factory with tools and invoicing per quality components produced - a 100% tool management between two powerful partners.

Modern cutting tools used in industrial manufacturing are characterized as follows: the base material, the cutting geometry and the surface coating. Together, these three factors determine the field of application and the productivity of the tools.
With special research departments in each of these key fields, Guhring is uniquely positioned to provide expert R&D know-how in each of these vital competencies. The close communication between the respective research departments has made Guhring one of the world leader in cutting tool R&D. Modern technologies are used in order to match the cutting tool geometries to the broadest possible range of rotating cutting tool applications. The properties of various commercial grades of carbide are optimized for both standard production and specialist applications at Guhring's Carbide Plant.
Today Guhring offers eight haed coatings for wear protection and the glide coating MolyGlide. Other coatings are developed at the moment and will be available for future cutting operations.

This multilayer coating is applied to HSS and carbide drills. It offers outstanding wear resistance in drilling operations and high heat resistance. Besides conventional wet applications this coating is suitable for minimum lubrication and dry machining, often combined with MolyGlide to optimize the running-in wear and improved resistance to galling.

The well established A-coating has been developed at Guhring. By optimizing the structural, chemical and mechanical properties of the new Super A-coating an extremely high hot hardness, very good oxidation resistance and excellent coating adhesion have been achieved. This coating is used exclusively on carbide cutting tools and is ideally suited for difficult to machine aerospace materials such as titanium alloys, Inconel as well as machining hardened steel materials (>52 HRC) and HSC applications.

This new coating developed by Guhring is suited to a range of applications, including dry and minimum quantity lubrication machining, high-speed cutting and machining highly abrasive materials. The coating is recommend when cutting difficult-to-machine materials such as MMC, GGV and titanium alloys as well as for machining hard materials (<52 HRC). The extreme machining conditions are made possible due to the high coating hardness as well as the optimized oxidation stability. The layer effectively forms a thermal barrier over the coated tool, so that the heat generated during machining is dissipated almost completely by the evacuated chips.
