High-Feed Cutters Improve Tool Life
Ingersoll Cutting Tools will show its Hi-QuadF line of high-feed cutters. The cutters are available with a 13-mm and a 19-mm IC quad-style insert, which provides four cutting edges with a choice of eight different cutting edge geometries. The maximum depth of cut ranges from 0.088" for the 13-mm IC insert to 0.145" for the 19-mm IC insert.
According to the company, the insert grades coupled with edge preparations ensure long tool life, even with demanding applications across a range of materials. A positive axial insert orientation creates a high-shear, free-cutting nature for the Hi-QuadF cutters. Chip thinning is leveraged to a factor of 5× when calculating feed rates. A robust insert screw design secures the insert in the pocket, ensuring cutter performance and insert seating stability.
Consider these alternatives when conventional drilling can't do the job.
Economic efficiency is an important consideration when choosing tools for challenging metals.
Running rotary milling cutters at the proper speeds and feeds is critical to obtaining long tool life and superior results, and a good place to start is with the manufacturer's recommendations. These formulas and tips provide useful guidelines.
