Trochoidal Milling of a Titanium Blisk using Cryogenic Tool Cooling and MQL
The Romicron PCD tooling portfolio is offered in diameters from 4 to 213 mm and the developer claims it will reduce setup times and scrap rates and increase overall equipment efficiency Itrsquos a fineboring system suitable for most materials commonly found in metalcutting Romicron PCD is one of numerous new additions to Kennametalrsquos holemaking product line
This sketch details the concept for setting up three cutters to perform precision machining of thin slot and surface under angles

A closeup view of the holemaking process shows the Ingersoll HiFeed Deka face mill producing chips partway through a complete hole The tool withstands the lateral and impact forces associated with corkscrew milling the developer noted and because it has twice the diameter of the previous solidcarbide end mill it is less susceptible to deflection and it leaves no slug
Productivity improvements in holemaking are based to a large extent on higher penetration rates With the CoroDrill 860 solid carbide drill this is achieved primarily by higher cuttingspeed capacity combined with the higher process security

The secuRgrip antipull system locks the collet and cutter to the toolholder body to eliminate cutter slippage
