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.
