Aßling, Germany, November 04, 2021–( PR.com)– The steel and cast iron product group is a tough one for milling tools to manage, not least due to the fact that of the range of alloys that can be utilized and all the various homes they have. On the one hand, the tools require to be able to hold up against substantial quantities of pressure, for instance due to the high tensile strength of steel (as much as 1400 N/mm2) and the unequal structure of cast iron. On the other hand, really soft alloys need geometries that are beneficial for cutting in order to guarantee that the product can be machined efficiently.
The H&V EXPK1 Series has actually been established specifically with these requirements for cutting steel and cast iron in mind. The producer has actually currently gotten preliminary favorable responses from numerous markets, such as mold and pass away making, maker and plant building and the vehicle market.
Optimization to the tiniest information
For its brand-new generation of milling cutters, the producer has actually made it its objective to make no compromises. In order to fulfill its claim of “the best tool for every single application,” an item portfolio including an overall of 800 specific posts (48 short article groups) was developed. In this procedure, not just the geometries were refined, however likewise an unique fine-grain substrate with tested solidity and increased fracture strength was picked, along with the tolerances were enhanced for optimum precision ( ± 0.003 mm or ± 0.005 mm depending upon the tool type and radius).
Maximum efficiency is accomplished by utilizing the current finish innovation. In addition, they have actually made it their objective to fix the troublesome distinctions in between damp and dry machining and have actually produced particular professionals where it is crucial. Even more to detailed technological updates, the 8 brand-new milling cutter key ins the series likewise suit the brand-new H&V identifying. These are: Performmaker (end mill cutter), Slotmaker (roughing cutter), Chipmaker (trochoidal cutter), Mirrormaker (completing cutter), Formmaker (torus cutter), Blademaker (face torus cutter), Rowmaker (complete radius cutter).
One emphasize of the brand-new series are the brand-new chipmakers (trochoidal cutter) with enhanced positioning and groove shape of the chip chambers, which impress with perfect chip disposal in trochoidal volume machining and hence avoid “chip nests.” This prevents the duplicated milling of chips that have actually remained in or collected so that the advancement of microbreakouts on the cutting edges are successfully avoided. The lower pressure angle of this geometry minimizes the produced heat throughout the milling procedure and thus likewise the thermal load. Process dependability and tool life are considerably increased. In order to use the best tool for each application, the maker has actually created both a 5- and a seven-flute milling cutter for trochoidal machining on function.
The five-flute chipmaker is chosen for high lateral infeed due to its variety of flutes and the chip area groove size. The device mechanics are subjected to a lower load, which makes it preferably ideal for makers with lower characteristics.
The effective seven-flute chipmaker, for its part, accomplishes greater feed rates with much better characteristics and at the exact same time less load on the milling spindle.
The rivals’ tools might not stay up to date with these tool lives.
The truth that the tools of the EXPK1 series are actually “hard as nails” is shown in internal tests performed at Hofmann & Vratny’s research study and advancement center in addition to in detailed field tests. The brand-new Performmakers (end mill cutters) score especially well when machining with high radial cutting depths even with complete slot milling. These cutters likewise master ramping and helical immersion with high procedure dependability. In spite of the longest tool life, the brand-new chipmakers (trochoidal cutters) had actually not yet reached their limitation of wear by a long method compared to the tools of the rivals and likewise persuaded the clients above all with regard to spindle load, chip elimination and milling sound.
The brand-new Rowmakers (complete radius cutters) accomplished the greatest tool life not just in dry machining however likewise in crushing with cooling lube.
Radial and axial in addition to thrusting and tensile loads were evaluated on the tool. Picked mold making clients who have actually currently evaluated the tools completely are encouraged in regards to tool life, dimensional precision and surface area quality.
Alpha Ferro Platin X– brand-new high-performance covering
The basic coverings for machining steel, such as TiAIN finishes, have actually ended up being so reputable on the marketplace thanks to their typically strong residential or commercial properties when utilized for universal machining. In order to accomplish this level of viability for universal usage in all steel and cast iron alloys while enhancing even further on the efficiency of the TiSiN-Alpha finish formerly utilized by the producer, the brand-new Alpha Ferro Platin X was constructed on an unique idea including AlCrTiN (aluminum chromium titanium nitride). The primary benefits of the brand-new covering are identified by its increased temperature level stability throughout dry machining in addition to its thermal resistance when damp machining, greater wear resistance and optimum stability of the cutting edges. In addition, a brand-new ending up technique has actually been established which is identified by its accomplished smoothness and therefore avoids microbreakouts. The ending up guarantees a completely ideal chip elimination and even use.
