Titanium Spindle

Titanium Spindle
What is the minimum rpm of the screw factory aluminum W / CNC milling machine?

Update my shop for buying a CNC milling machine that can produce at home. However, I would be able to mill steel, stainless steel, titanium and aluminum. The steel and titanium that I know are low PGR rates for milling, due to hardness. What is the number of revolutions of the spindle minimum allowed for me to buy a mill that is capable of grinding all the above material?

Depends on the size of the tool. For 2024-T4/T6, 2014, 6061-T6/T651, types 7075-T6 aluminum, you want a speed of 800-2000 FPM court that for a 1 / 4 "would be a tool minum of 12,200 RPM. for 440, 356, 380, C61300 types of aluminum, use 500-1000 FPM. The formula for converting TP FPM RPM is: Spindle Speed [RPM] = cutting speed (inches) (* pi diameter of the tool). / Basically, find the circumference of the tool, cutting speed divide the circumference of the tool that tells you how many times the tool will have to spend a few minutes to reach the proper cutting speed. A larger diameter tool will be slower, since more than scrap metal by the revolution of the tool.
