Belt drive upgrade for Sieg X1 micro mill : r/Machinists
WEBBelt drive upgrade for Sieg X1 micro mill. Belt drive upgrade for my Sieg X1 micro mill. Runs much quieter than the stock gearbox! Looks better too! Maximum measured spindle speed is ~2850, ~1750, and ~950 RPM respectively. Will definitely help with the smaller drills and endmills (smallest endmill I have is a 2flute 3/32″)
