High Speed Auxiliary Mill Spindle
An easy to make auxiliary high speed spindle that
will allow you to utilize very small diameter end mills without
a high probability of breakage. Spindle RPM's of most home shop
milling machines are simply too slow for end mills smaller than
around 1/16" (1.6mm). Depending on the motor used and the
pulley ratio, speeds of 8,000 RPM and much higher are available.
The spindle is designed to accept 3/16" shank diameter end
mills which is common for end mills from 1/32" to 3/16"
diameter. The spindle body is mounted in a standard 3/4"
or 7/8" R-8 collet. The drive belt is a standard low cost
"O" ring. The unit is adaptable to a wide range of modifications
to suit any user. The plans set also includes an oversize computer
grade precision lower ball bearing, a high quality upper ball
bearing and a bearing preload wave washer.
The plans set consists of 5 sheets of drawings, 1 sheet of helpful
notes, spindle bearings & preload washer.
