Replaceable Tip End Mill Design

Seco Tools, LLC introduced its Minimaster Plus replaceable tip milling system that features a large selection of inserts and shanks for tackling a broad range of applications. Most recently, the company added new through-tool coolant high-feed heads to the system to further advance its versatility as well as increase tool life and improve chip evacuation.

Intended for general machining in the aerospace, power generation, die and mold, automotive and medical industries, the Minimaster Plus is engineered to cut steel, stainless steel, cast iron, aluminum and other difficult-to-machine materials. It also makes tool-length remeasurement obsolete.

One of the Minimaster Plus system's features is its high-precision interface between the replaceable carbide insert and the steel shank. The insert has an internal thread and external taper, while the shank has an internal taper with a threaded center pin for added reliability and stability as well as a run-out of approximately 10 microns.

Additionally, an axial stop on the shank allows end users to replace an insert without having to remove the tool from machine spindles. The new insert then repositions axially within 25 microns.

The system's shank comes in 24 versions with lengths that range from 2.2" to 9.8". Inserts are available in two grades for machining all types of materials and E- and M-geometries for a smooth cutting design. Insert diameter options are 0.39", 0.47" and 0.63", and corner radii are available from 0.0157" to 0.122" to match a variety of design requirements. Furthermore, the system's square shoulder and ballnose inserts have through-tool coolant on all two- and three-flute designs.
