FIREX: Guhring's new coating system The red violet F-coat pm TiAlN-TiN basis combines the advantages of the TiN-, TiAlN- and TiCN coat and offers incredible universal application possibilities. The tooling system T800 The first tooling system for indexable inserts made of high speed steel and carbide - the economical alternative to carbide and high speed steel drills < Ø 16 mm. The ratio drills RT 150 The RT 150 GG ensures accuracy an productivity The specialist for deep holes over 7 × D: Type RT 150 GN with negative helix. Performance-drills with wave cut of HSS & HSCO Drills with wave cut have the advantage increased tool life and better chip breaking than with normal drills. Literature: Modern Cutting Tools Technology 20 Is Eco tooling on the way in? The pros and cons of dry machining tehniques For many years past we have striven to attain the goal of optimal tool cooling based largely on the principle of introducing coolant, under pressure, through internal ducts in the drill body. Now, suddenly a new possibility opens up: coolant-free Eco tooling: in other words a technological U-turn. Is Eco tooling really superior? We have developed new cutting materials, carried out test runs and cost comparisons. The GT 80 IK oil feed drill Tungsten carbide drills need rigid, powerful machines. Only then can they save money. But what is the alternative if such sophisticated machines are not available? Our answer is the GT 80 IK. 3 snags and solutions of practical interest to all engineers Modern Cutting Tools Technology 21 Fast, faster, the fastest: Pros & cons of high speed machining The cutting world is currently divided into 2 camps. While one side stands up for dry machining, the others favor high speed machining (HSC). In issue 20 we shed light on the pros & cons of dry machining. In this issue we begin with the arguments for and against HSC-milling and -drilling. The ideal new combination: Ratio drill + chamfer collar = drill/chamfer tool Specially developed for the cost effective production of drilling and countersinking in one operation. 5 snags and solutions of practical interest to all engineers Modern Cutting Tools Technology 22 Which coating will give you money in the bank? Hard surface coated tools only suit mass production - this is the often opinion of far too many users. We would therefore like to use this article to illustrate that it is worthwile keeping coated tools in mind even for small batches and also bring you up-to-dae with coatings and their applications. Stop press: MOVIC® rationalises dry machining For once a completely different coating: Not a hard coating, not a protection against wear and tear, but a soft coating, a glide coating, thereby integrating the lubricant in the tool! This was the idea leading to the development of the M-coating. Here we describe the initial, thrend setting findings. The most important: M-coating rationalises dry machining. Furthermore, dry HSC machining no longer remains an utopian dream. 4 snags and solutions of practical interest to all engineers Modern Cutting Tools Technology 23 After more than a century: 3 way attack revolutionizes drilling The geometry of the standard drill has not seen any changes or improvements in the last 130 years. But now, in 1997, we not only introduce one historical improvement but three! Guhring's most recent service: Existing machines dehydrated Do you consider using dry machining? But don't want a large initial investment? Have plenty of questions? Guhring can now tell you how to dehydrate your existing machines step by step 4 snags and solution of practical interest to all engineers F for FIREX: F-coat achieves quantum leap
