SHORT FLUTE LENGTHS
Seco continues to build upon its industry leading Minimaster Plus family with the development of new shorter flute lengths – the first of many planned product line additions. As part of the popular replaceable cutting head tool system, the new Minimaster Plus cutting heads with shorter flutes will handle higher cutting forces and, in turn, deliver increased metal removal rates in roughing and semi-finishing operations.
The new cutters incorporate all of the same design features and benefits as existing Minimaster Plus cutting heads, only in shorter flute lengths. Existing flute lengths are 1.2 x D, while the new additions are 0.7 x D, which significantly boosts their stability.
Added stability makes the shorter lengths especially well suited for aggressive material removal in demanding applications and 5-axis machining where cutter ends are used more frequently than the entire flute lengths. Ideal machining conditions for the new cutters are those where radial engagement is much greater than axial engagement, as compared to the opposite conditions where longer flutes would be used.
The shorter cutting heads are available with the same corner radii and geometries, as well as in the same coatings and grades, as existing Minimaster Plus cutting heads. They also work with the entire existing shank range. Industry segments that will benefit the most from the new lengths include aerospace, mould & die, and general contract machining.
NEW FOUR-FLUTE VERSION OPTIMISES CUTTING PARAMETERS
Seco introduces a new four-flute version into its industry leading Minimaster Plus replaceable cutting head tool system. The four-flute version joins an existing three-flute head, and both handle higher cutting forces and, in turn, deliver increased metal removal rates in roughing and semi-finishing operations. The four-flute head features larger helix angles, but incorporates all of the same design features and benefits as existing Minimaster Plus cutting heads. The shorter flute lengths measure 0.7xD, which significantly boosts their stability.
