PERFORMANCE WITHOUT COST INCREASE
This deep face milling was born in the Cleveland Golf CNC shop by experimenting with primarily milling depths but also tool diameters, mill-bit geometry, spindle speeds, and feed rates. The purpose of the project was to develop a softer feeling putter face without increasing cost. The end result, as seen above, is a 0.015” deep face milling compared to the 0.003” industry standard. What the combination of milling depth, path location and pitch gives us is a face with less surface area contacting the ball at impact, which means increased energy loss and ultimately a softer feel similar to polymer inserts but more precise and at a fraction of the cost.
