    JBO shark - Efficiency through innovation

    Thread milling cutter

    Biting competitor


With the 'Shark', we are launching a thread milling tool that clearly surpasses conventional tool concepts in terms of productivity and tool life. The multi-tooth milling cutter is available in three versions for a wide range of materials. 

It naturally causes quite a stir when a company experienced in the technology of thread production promises its circle of users a "high increase in productivity with even better quality" with the latest new tool development. Nothing else has happened with the presentation of the current thread milling cutter 'Shark’. 

We see ourselves as one of the leading international suppliers for thread machining and testing. Already in the sixth generation, we develop and produce our products without exception at the Albstadt site. For more than a hundred years, we have been intensively involved with the subject of threads. Our partners worldwide should profit from this consistent specialization and the comprehensive knowledge in this field. This is also the case with the Shark thread milling cutter.

Experience and user requirements flowed into the new development 

    For the completely newly developed high-performance thread milling cutter series, we have drawn on various in-house developments of the past years and combined all positive findings in one tool. The high-performance thread milling cutter Shark had passed all in-house and user tests dealing with the production of internal threads of any kind with flying colors. Given the ever-increasing output and part quality requirements faced by industrial users, our designers were looking for a significant step forward in productivity, while at the same time making the tool resistant to mechanical wear. With the catchy name Shark, we refer to the range of characteristics that he attributes to his latest product: strong, goal-oriented, determined and aggressive. For the user, this means that the tool's bite is intuitively perceptible in the actual manufacturing process, while at the same time offering pronounced stability. This subjective perception is ultimately reflected in concrete parameters in connection with the productivity factor. The high-performance thread milling cutter is universally applicable and suitable for machining a wide range of materials. Steel and cast iron materials as well as non-ferrous metals and nickel alloys are no problem for it. It is right-hand cutting but left-hand spiral. Its unequal spiral pitch makes the Shark extremely low in vibration, thus enabling it to be used under difficult practical conditions. At the same time, a high surface quality is achieved in the component due to this special design feature. The large number of teeth and a new, progressive flute design also contribute to the achievable increase in productivity. 


The processing time reduced by more than two thirds in some cases


The threading tool is characterized by short cycle times. For example, in comparative machining tests with two competitor products, the Shark achieved a significant reduction in machining time of 2.47 s compared to 3.73 s and 9.50 s. The results were similar with regard to tool life. Similarly good results were achieved with regard to tool life. The results of a representative series of tests can be summarized as follows: with all three of the Shark tools examined, tool life of more than 7,000 threads was achieved, whereas the three tools of the two competitors only achieved tool life of almost 2,500 or even just under 1,000.

The thread milling cutter is available in three basic versions. The first, the GFShark, is designed for metric regular threads. It has a straight shank and a cutting edge length of 2 × D. All its sub-variants (M3 to M14) are supplied with cooling channel. Due to its special design, it can be used to produce fine threads containing gauges starting from the nominal thread diameter of the of the standard thread. For example, an M 8 × 1 thread or an M 12 × 1 thread can be produced with a GFShark M6.The GFMShark multi-range thread milling cutter for standard and fine threads is available from stock for a nominal thread diameter of 14 mm for a metric pitch of 1 mm, 1.5 mm, 2 mm and 3 mm in the standard program. Other dimensions can be produced as special tools without any problems and in the shortest possible delivery time. The GFTShark is used for metric regular threads on thin-walled components, for small thread dimensions and for deep threads. It has three full thread profiles and can machine a thread depth up to 3 × D. From size M4, the series is equipped with cooling channel. A straight shank is used as the holder.

Development and testing as a permanent process

Stagnation is regression; further developments are the measure of all things. The very good understanding of the customers' processes, the expert selection of materials, the use of sophisticated processes and the professional, highly motivated commitment of our employees are always a guarantee for innovative, progressive solutions. All new developments are tested in Albstadt on machine tools that are provided exclusively for trials. They are used to put new developments through their paces down to the smallest detail - this is also what happened with the Shark thread milling cutter series. It was completely developed and optimized in-house.
