Preamble...
Having owned my ML7 lathe for some
30+ years I learned to live with the vagaries of the spindle
drip lubrication system. However, fitting an inverter and
3ph motor and running it at higher speeds set me wondering
if such hit and miss lubrication was adequate.
After much pondering I came up
with the idea of using a peristaltic pump driven by a
stepper motor turning X number of steps to deliver a metered
quantity of oil to each bearing, the stepper timing being
controlled by an Arduino. After several prototypes and may
hours of testing, it worked to a degree but I wasn¡¯t happy
with the repeatability nor my ability to write code for the
Arduino.
