CNC milling has been used for a while, especially on putters and on iron faces. We have started to see a few companies do the soles of wedges, backs of irons, etc. Definitely more CNC capability with todays technology in the factories where most of the clubs are being made, for sure. CNC is more expensive to do and even if a product is cast or forged and then skin milled, as opposed to 100% CNC, it adds to the cost. It does produce precise parts, but so does the forging process and investment casting process when done properly. I think seeing milling marks on a part gives the parts more of an industrial look, and I think that is popular right now. I also think that CNC is definitely here to stay in producing club heads, specifically putters, irons and wedges. I do not think you will see irons and wedges completely, 100% CNC milled from blocks of material, but skin milling portions of designs will continue. Putters are and have been produced by CNC milling from blocks of material for quite some time. Still, forging or casting a putter and then skin milling is the more common process.
