VIDEO: FBX Drill – High Metal Removal Rates Through Large Diameter Drilling

This is the FBX drill, the brand new modular drill designed for maximum metal removal rates in aerospace structural component machining. The FBX drill is part of a tooling concept including the HARVI Ultra 8x and the HARVI end mill series specifically designed to increase productivity for these types of applications.

Today we're not focusing on cycle times or on metal removal rates or this tool over that tool. We're focusing on showing you all the options that this giant drill provides. Quickly removing large amounts of material remains a challenge for these types of components. High feed rates require powerful machines and large depth of cut like we see here creates large radial forces and a high bending moment which requires machines that are also very rigid. The FBX drill can be the solution for those machines that have the power but not enough rigidity. The flat bottom design eliminates radial forces while four effective cutting edges provide increased feed and speed rates. Aerospace structural parts are usually made from large plates or forgings. The most commonly used material is titanium like ti-6al4v, but high-strength stainless steels like 15.5 ph are also used. For these components we're going to show you how the FBX drill can be applied on both types of components and materials.

In this large plate of 15.5 ph stainless steel, we're creating a square pocket and a triangular pocket. Starting with the square pocket we'll drill into solid material first. Then we'll remove all the remaining material with the HARVI Ultra 8x cutter. After that we'll create this triangular pocket here. This time most of the material will be removed with the FBX drill by drilling chain holes and by plunging. Once the drill has created the basic shape of the pocket, the scallops will be removed with the HARVI Ultra 8x cutter.

The HARVI 3 series end mill will then finish the inside walls of both pockets. After that we're going to switch to this component here same 15-5 ph stainless steel material which simulates the typical shape of a forging. A regular drill would simply fail on a work piece like this. We'll create three holes. With the flat bottom design, the FBX drill has no problem with these challenges.
