Mitsubishi Materials expands TriForce grooving system

The latest addition of internal and face grooving tools to the series ensures nearly all grooving application needs are covered. In addition, three new grades are available, a CVD-coated grade MY5015 for cast iron and steel, a Cermet grade, NX2525, for finishing, and a long life CBN grade, MB8025, for finishing hardened steel. The modular system allows a variable tool selection, while maintaining the important, overall rigidity and clamping strength. Additionally, a wide variety of inserts for the TriForce range makes it possible to cover a diverse area of machining applications, ensuring high efficiency, precision machining. Ten Insert widths are available, ranging from 2.0 - 6.35 mm. Corner radii are available as standard, with four sizes of radii available, from 0.2 to 0.8 mm. Additionally, five different chip breakers are offered to cover various applications, such as grooving, parting off, turning and copying. Good chip control and excellent surface finishes can be obtained with Miracle-coated VP10RT and VP20RT grades for steel machining. TriForce's clamping system ensures that tool blades are securely held from three directions - side, front and top. This leads to high tool rigidity, comparable to a mono block type holders, and ensures TriForce tools can also produce results of the quality normally associated with solid holders. Additionally, the modular system improves tool management by reducing tool stock and has the benefit that one toolholder can be used with several different blades. These blades are interchangeable, so that different lengths can be used for different applications and, also, if tool breakage occurs, it is only necessary to change the blade, making it economically advantageous.
