| tend chip when they really start chattering
Your part isnt held right. or End mill is to long or your taking more then 50% of dia. in cut. or to little mat. left and its acting like a trampoline. Coated tooling dosnt chip any easyer. Carbide is what chips easy. You can get coated HSS and carbid. in tin, ticn tian, tiain cvd.
R8 is good way to hold tooling. Get solid holders for endmills and use collets for drills and the likes. Tons and tons of R8 can be had used and the new imports are ok. I dont like them because it just bothers me.
Just run at the right rpm and you will be fine. Belt drive is good because belts are a lot cheaper to replace and if you crash the belt should slip first.
Get a good edge finder. there like 14.00 to 18.00 dollers. If its manual machine dont climb mill. and work in the same direction due to back lash.
