please, questions about lathe service
hello please, i have a few questions :
- how to verify torque for :
... a specific rpm on m-spindle, vdi turret ?
... s-spindle : specific rpm, m19, m147 and m110 ?
- how would you align a dial indicator, so to have its palpator parallel to X axis, pointing towards the spindle center, on a lathe without Y axis ?
- let's say that there was a crash : turret, spindle and tailstock, are all out of alignment : which is the 1st thing that you align, why, and how ?
- let's say that there was (another) crash : only main spindle is out of alignment, and if you wish to turn a cylinder, you will obtain a cone :
... how do you rotate the spindle back, to be parallel to z axis, verifying without moving the turret after the spindle was rotated ? thus, after spindle rotation, you have to be sure that you will obtain a cylinder by cutting, even if you don't move the turret ( thus, is not allowed to verify by machining, nor by moving the turret, nor by moving the tailstock );* idea behind this is minimal alignment time, one-shot rotation
... once the spindle will be again parallel to z axis, there is a big chance for the spindle-axis and id-toolholder-axis to be parallel instead of being coaxial; let's say that by using a centro, you discover that missalingment is only among Y axis, and X axis is fine : to achieve coaxiality among Y axis, do you align the spindle, or the turret, or both ? pls, remember that turret alignment is ok
- let's say that there was a 3rd crash : only tailstock is out of alignment, and tailstock axis is no longer coaxial/paralel with spindle axis; how do you rotate the tailstock, to be again paralel to spindle axis, without verifing it by moving the turret ? thus you should rotate the tailstock in such a way, that you will be sure that it is paralel to the spindle, even if you don't check it by moving the turret; you may move the turret to find the tilt before begining to rotate the tailstock, but you may not move the turret to verify the alignment after rotating the tailstock; * idea behind this is minimal alignment time, one-shot rotation
