Taig Micro Mill
Speeds and Feeds

This table gives several examples of speeds and feeds for the Taig micro mill. It assumes 1/8 HP Taig motor, using HSS center cutting end mills. Unlike formula approaches, this data is based on real-world experience. Although further optimizations are possible this data is the result of time consuming experimentation. Comments and corrections are welcome. (The "?" mark indicates some uncertainty resulting from incomplete original notes.) For situations not listed on the table you should find the nearest situation and estimate.

Columns:

• Depth = cutting depth X .001" 
• Diam = diameter of endmill X .001" 
• Flts = endmill flute count 
• Pulley = Taig pulley 1=slowest, 6=fastest 
• RPM = Speed based on Taig docs which indicate following RPM for 6 pulley settings: 1100, 1900, 2900, 4300, 6500, 10,500.
• Cut = horizontal cutting speed inches/sec 
• Quality = quality of cut considering clean edges etc 
• Z = vertical cutting speed inches/sec using center cutting endmill

For metals except brass used Magic Tap brushed on surface; no lube on brass and non-metals.
