Just had this video recommended on the YT homepage. New subscriber. Large nose radii with a very slow feed rate has produced the best results on my smaller mill. Grind up a HSS blank for old time sake! Cheers man.
Thank you for watching and subscribing. My original thought was to grind a HSS blank, not sure how much justice I will do the grind 🫣, but will definitely give it a go.
Reducing the cutting diameter to just wider than the part greatly reduces the impact on the tool. This leads to a better finish and less shock on the spindle bearings. You can run the spindle faster too with a more balanced tool. The technique is called tangential engagement.
Thank you for the feedback, I fully agree. Depth of cut using carbide inserts also makes a big difference. I've noticed on the lathe that an aggressive cut gives me a better finish.
🤣 I can honestly say they were there when I got the mill and vice second hand. But it still haunts me too 🫣. I've been thinking about drilling them into uniform holes then plugging them with some bar stock or just filling them with some resin as is.

Thank you for the advice. I'll definitely give it a try. Changing speeds is just a nightmare with a belt drive.
Power feed is the key to a good surface finish. The button round inserts are great for aluminum..

Any imbalance, the slightest vibration in quill or spindel will get amplified and transmitted to the cutter.
A few witness marks on that vise 😂, I have one on my rotary table that haunts me everytime I use it.

Your feed rate seems way too fast to me.
