Milling Tools

Milling is the work of producing a flat or contoured surface on a workpiece with a rotating tool. The work can be done on a machining center or milling machine, and can also be done on a turning center that has rotary or “live tool” capabilities. The tools for milling include both solid tools and “indexable” tools—the latter consisting of a tool body that uses replaceable cutting inserts. Carbide is the most likely material for milling tools, though high speed steel is another choice, as are ceramic, cermet and diamond tools in certain more demanding milling applications. The end mill can be flat-bottomed for flat surfaces, or ball-nosed for milling up contoured shapes. Another common milling tool variety is the “face mill,” a generally larger-diameter tool designed for efficiently milling a wide, flat surface in an economical number of passes.

Optimized Machining out of the Box

By: Peter Zelinski
Four tooling-related companies partner to supply dynamically stable milling for improved productivity on existing machine tools. Users do not have to measure the dynamics of their machines. Instead, tooling tailored to the machine arrives as a complete assembly, along with software for quickly determining the parameters that tooling can be used to achieve.
