This small-diameter and flute-shaped end mill is a tool specially designed to achieve deep, direct and precise machining or cutting of hardened steels. Aside from being highly efficient, it is also a great time-saving equipment as it shortens the processing steps or mold delivery times right after the tempering operation. Reproduces accuracy and performance équivalent to a new product. Recycling kills two birds with one stone by reducing costs and being environmentally friendly. ■Regrinding of the oval shape to be équivalent to that of new products is possible, without changing the tool diameter of course. ■Regrinding and recoating is performed according to Processing knowhow and design standards based on new products. ■Since reprocessing is performed under the same environment using the same Processing software, coating, and quality control mechanisms as when manufacturing new products, accuracy and tool life équivalent to that of new products can be reproduced. ■Although flûte length is shorter when reprocessing is performed, on the other hand rigidity is a benefit. The corner R flûte shape used is the same chipping-resistant high-rigidity flûte type used by Epoch Turbo Mills. Because of this, machining with high per-flute feed amounts is possible and high-efficient machining can be achieved. A newiy developed nanocomposite coating material that achieves unprecedented withstand températures and provides higher hardness through the use of a new structure made up of nanocrystal material. (Oxidation start température: 1100° C; Membrane hardness: 3600HV) Enables high-quality machining with long life of hardened Steel (45 to 65HRC), pre-hardened Steel, etc.
