2.12 SOLID TAP FUNCTION
Solid tap functions can be optionally added to YASNAC
J50M.
These functions are performed
completely syn-
chronizing the spindle revolution and Z–axis feed
for tapping.
They eliminate the need for a float-
ing chuck and ensure tapping operation at high
speed and high accuracy.
Conventional tapping can also be specified by the
program.
