MFH Mini Endmill

June 01, 2015

Kyocera Precision Tool Inc. announced the launch of the MFH Mini, a small-diameter, high-feed endmill for processing metal parts. The new product achieves highly efficient processing utilizing the company's proprietary, newly designed insert.

A high-feed endmill is a cutting tool utilized to rough cut the surface of metal across a broad area. The insert requires high cutting capability, which allows for quicker and more stable processing of the workpiece. To meet these needs, Kyocera developed the MFH-Raptor, a high-efficiency, high-feed cutter, in 2014. After its introduction, to support higher-precision cutting technology required for processing molds, Kyocera developed the small-diameter, high-feed MFH Mini endmill.

The MFH Mini is a small-diameter, high-feed endmill for rough processing consisting of a newly developed insert and dedicated holder. The insert features a unique design, which reduces impact on the insert when making initial contact with the workpiece, thus achieving smooth cutting with low resistanc. As a result, the product reduces chattering and enables increased feed rates. In addition, the MFH Mini exhibits high chip evacuation due to the design of the newly developed chipbreaker.

This product is available with both a CVD and PVD coated insert. Utilizing an insert with the ideal coating based on work material characteristics enables the endmill to deliver optimal wear and fracture resistance.

Through an enhanced feed rate, excellent chip evacuation performance and an optimal insert lineup, the new MFH Mini achieves highly efficient, stable processing and contributes to productivity improvements.

  • chemical vapor deposition ( CVD)

    chemical vapor deposition ( CVD)

    High-temperature (1,000° C or higher), atmosphere-controlled process in which a chemical reaction is induced for the purpose of depositing a coating 2µm to 12µm thick on a tool’s surface. See coated tools; PVD, physical vapor deposition.

  • chipbreaker

    chipbreaker

    Groove or other tool geometry that breaks chips into small fragments as they come off the workpiece. Designed to prevent chips from becoming so long that they are difficult to control, catch in turning parts and cause safety problems.

  • endmill

    endmill

    Milling cutter held by its shank that cuts on its periphery and, if so configured, on its free end. Takes a variety of shapes (single- and double-end, roughing, ballnose and cup-end) and sizes (stub, medium, long and extra-long). Also comes with differing numbers of flutes.

  • feed

    feed

    Rate of change of position of the tool as a whole, relative to the workpiece while cutting.

  • physical vapor deposition ( PVD)

    physical vapor deposition ( PVD)

    Tool-coating process performed at low temperature (500° C), compared to chemical vapor deposition (1,000° C). Employs electric field to generate necessary heat for depositing coating on a tool’s surface. See CVD, chemical vapor deposition.
