Metav 2016 – Tool Sector Metav as Showcase for Tool Innovations

The Metav 2016 in Düsseldorf is also welcome to suppliers of precision tools as a platform for presenting new products. The special focus here is on solutions which bring noticeable savings in time and costs.

Higher power and reduced processing times combined with process security — these are the essential advantages of the innovations in the tool sector presented at the Metav 2016. One example is the novel HCP-IQ drill head geometry, with which Iscar has expanded its Sumocham replaceable head drilling system. With these drill heads, available in steps of 0.1 mm in the diameter range 8 to 25.9 mm, we hear, workpieces in ISO-P (steel) and ISO-K (cast iron) can be processed especially efficiently.

Besides a general improvement in performance, the development of the new cutting geometry focused on significantly improving the centring capability, Iscar tells us. Thanks to the concave geometry and the new crosscut concept, axial forces and torque values during the onset of the drilling process are reduced significantly. According to the supplier, the various optimised geometries improve the centring capability significantly, enabling bore depths of up to 12 × D without pilot bores. Due to the elimination of the pilot bores, the number of tools necessary is reduced and the total processing time shortened by up to 40 %.

Fast and vibration-free processing of bores is promised by the EWD Smart Damper by Big Kaiser, a precision boring head with damping technology and digital display. The boring head reduces vibrations and chatter during the processing of deep bores, thus providing better service characteristics and raising the cutting performance, the maker says. Processing with high cutting parameters is possible; very short processing times can be realised. “With its dynamic vibration damping, the precision boring head increases productivity ten times and leads to longer service life times,” as Ralf Winterholer, CEO of the Big Kaiser GmbH in Vöhringen, emphasises. The large digital display shows the part of the adjustment range in use, in relation to the diameter, to 0.001 mm. “This helps to avoid operating mistakes and makes complicated Vernier marking unnecessary,” Winterholer remarks.

Hard metal end-mill with vibration damping characteristics

Vibration damping also plays an important role in the new mills by Franken, the milling technology specialist in the Emuge-Franken group of companies. The hard metal end-mills for trochoidal processing are available in Jet-Cut geometry for applications in steel or cast iron working materials as well as TiNox geometry for applications in stainless steel materials and various alloys. Both variants are available in three lengths (2 × D, 3 × D, 4 × D). To meet the requirements of trochoidal machining, the end-mills are provided with vibration damping characteristics such as unequal pitch, unequal helix angles or a new micro-geometry. According to the maker, newly developed chip breakers reduce the axial extraction force on the tool and minimise the risk of a chip jam in recesses.

New end-mills are also being shown in Düsseldorf by Kyocera. The 4TFK/4TFR range is said to be an efficient solution for processing hard-to-machine working materials such as titanium. According to the supplier’s information, a wide chip space and a large cutting angle lead to very good chip removal at high feed rates. The manufacturer's own PVD coating technology, Megacoat Nano, contributes to optimum strength and service lifetime.
