Higher-precision mold processing, shorter lead times and lower costs

「① Development of the “PNS-REBORN” indexable face mill This indexable face mill enables high-efficiency machining with inserts featuring 10 usable corners on both sides.」

「We expanded the series of all-carbide shanks, the “Ganko Ittetsu MSN.”」

「We developed the EXSKS-05 indexable high-feed cutter, a small-diameter, multi-flute tool, and expanded the EXSKS series to support a broader range of machining applications.」

「We developed TS inserts that deliver high-precision, long-life finish machining in the high-speed machining of hardened materials.」

「In response to the need to consolidate processes by reducing setup operations and to machine complex shapes and improve machining accuracy, we developed a complete series of 8 tools for 5-axis machining, branded the “Jūō Mujin Series,” which enables machining from any direction in a single chucking.」

「The “Hard 1 Radius SFSR” is a 4-flute solid radius end mill with a flute length of 1D and increased core thickness for greater rigidity. Its neck shape allows for a shorter shank precision section and reduced projection length, improving runout accuracy and rigidity to enable high-precision machining.」

「During the 94th fiscal year, we worked on the themes below and developed a range of new products.」

「As demand intensifies in the die and mold machining industry for faster, higher-precision direct milling of hardened materials, we developed the “Hard 1 Ball SFSB,” which handles a broad range of operations from rough to finish machining of hardened materials up to 70 HRC.」

「With □10 mm-size inserts, the maximum depth of cut is 1.5 mm, and with □14 mm-size inserts, it is 2.5 mm. Even at these deep cuts, the tools offer low cutting resistance and maximize chip evacuation.」

「The Company added the “YOHW” finishing insert to its “QM Mill” high-efficiency mold-machining tool and achieved high-efficiency, high-precision machining.」

「Under these conditions, in cutting tools, the Group further expanded the product rollout of “New DH Coat,” a new coating for machining hardened materials, to extend the service life of its specialized mold-machining tools. It also launched a new high-efficiency indexable tool that allows both sides of the insert to be used, taking into consideration not only tool performance and cost efficiency but also the environment.」

「In cutting tools, the Company further advanced the commercialization of the new coating “New DH Coat,” developed last fiscal year for machining hardened materials, with the aim of improving the performance of its specialized mold-machining tools. It also introduced the higher-value-added superhard material known as a cubic boron nitride (CBN) sintered body into “Giant Radius” inserts for the high-precision indexable end mill “Mirror Ball,” among other new product initiatives.」

「As initiatives for the 90th fiscal year, we proposed achieving higher precision and shorter lead times in die and mold machining, as well as substantial cost reductions, by changing the conventional process of “steel → rough machining → heat treatment → finish machining” to “heat-treated steel → simultaneous rough and finish machining by direct milling.” Using this solid ball end mill, we achieved machining of workpieces with a hardness of 70 HRC,」
