dear all
im looking for advice with the new machine i just bought, it has a tapper towards the spindle( samller towards the spindle by 0.05mm on a 70mm cut) i can compinsate for this in the program but surly on a new machine this should exsist.
ive narrowed it down to 2 possible reasonds
A: the tool stock is not moving in a true staright axis and has a taper too it
B: the spindle is not true to the axis off the stool stock
i have had the straightness gauge on the blank while spinning and as it moves toward the chuck it is minuses of the gauge but in each 3 areas it measured (far right, middel, far left) they are straight . from this i feel that it must be the spindle is not true to axis of the machine.
please feel free to post comments and ideas.
Regards james
