DoTriple-Mill Series Inserts

Tungaloy Corp. is expanding its DoTriple-Mill series to include pressed-to-size inserts in Class M dimensional tolerance, to further strengthen its position in the facemilling market. DoTriple-Mill is Tungaloy’s latest facemill series, in which any set of square, octagonal or round inserts can be fit on a single cutter body.

The inserts are securely fixed to the cutter by a dovetail clamping mechanism, ensuring added insert reliability even during heavy milling. The current success of the ground-to-size G-class inserts of the DoTriple-Mill has now called for an addition of M-class insert assortments.

The SNMU insert is a square insert line that incorporates built-in wipers with 2 mm flat cutting edges, maximizing surface quality in roughing to finishing operations. The company says the insert increases chip evacuation and machining stability, particularly in milling smearing materials like stainless steel. The octagonal ONMU insert has 16 cutting edges and is built to maximize the cost-per-insert economy, featuring an identical chipbreaker design to that of the SNMU insert. The round insert line, the RNMU, features robust cutting edges, which provides benefits in milling unstable surfaces at a large DOC, as well as in high-feed milling with a light DOC.

The new M-class insert line includes two new CVD grades: T3225 and T1215, in addition to the existing AH3135 and AH120 grades. T3225 is best suited for steel and stainless steel milling, whereas T1215 is ideal for high-speed and high-performance milling of ductile cast iron and gray cast iron.

Related Glossary Terms

  • 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.

  • facemill

    facemill

    Milling cutter for cutting flat surfaces.

  • facemilling

    facemilling

    Form of milling that produces a flat surface generally at right angles to the rotating axis of a cutter having teeth or inserts both on its periphery and on its end face.

  • flat ( screw flat)

    flat ( screw flat)

    Flat surface machined into the shank of a cutting tool for enhanced holding of the tool.

  • gang cutting ( milling)

    gang cutting ( milling)

    Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.

  • milling

    milling

    Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.

  • tolerance

    tolerance

    Minimum and maximum amount a workpiece dimension is allowed to vary from a set standard and still be acceptable.
