Recommendation for step rate on the motor driver with direct drive 1:1 of the Z-axis
Recommendation for step rate on the motor driver with ratio 2:1 of the Z-axis
Keep in mind that conventional lathes on the Z axis rarely achieve a higher accuracy than 0.02-
0.05mm. This is due to the long lead screw, which cannot achieve higher accuracy due to ther
-
mal expansion and inaccuracies. It is therefore unnecessary to set the resolution to a few mi-
crometers.
MAXIMUM FEED SPEED
The maximum feed rate in mm/revolution is directly linked to the ratio of encoder pulses, mo
-
tor steps/revolution and the thread pitch of the lead screw. The maximum feed rate is decisive
for the maximum thread pitch you can produce. Please note, however, that threads with a pitch
of more than 8 mm are very rarely turned.
