NEW SPINDLE MOTOR for CNC LATHE?
Now that I have replaced the stepper motors in the Boxford CNC lathe, (see “New steppers for an old CNC lathe”) I am considering whether I might replace the spindle motor for the same reason… that it has become less powerful due to the age of its permanent magnets. Sometimes I am aware that it struggles to keep up the revs while cutting.
Watch the YouTube video about the next generation servo motors. They use modern rare earth magnets. They are powerful, compact and precise. And not cheap. Stuart T, who has the same Boxford CNC lathe as me, has suggested that these Clearpath motors would be suitable replacements for the ageing Boxford spindle motors .
