7.9 “O9104” RADIAL TAPPING SUB-PROGRAM
Sub-program “9104” activates the radial tapping cycle.
With this function the tapping tool enters with a feed equal to the tapping pitch, reverses the module
rotation, followed by simultaneous acceleration of the motor driven tool and the axis then the returns to
starting point.
The axial tapping cycle contains these codes:
• X => End of tapping absolute value
• F => Tapping pitch ( in mm/rev.)
• S => Motor driven tool rpm
• M => Module direction of rotation when entering (303 or 304)
On machines fitted with tool holder disk with axial seats (GT400M, GT500M and GT700M) to use the
tapping sub-program another two functions must be enabled:
• M341 Engagement of module to the turret disk PTO units
• M340 Disengagement of the module to the turret disk PTO units
Delivery of coolant only takes place through function M7.
Disabling of coolant delivery is through function M9.
Sub-program “9104” can be called up in single mode (by function G65) or in modal mode (by function
G66 eliminated at the end of cycle by G67).
NOTE. GRAZIANO SPA ADVISES USE OF RIGID COLLETS IN TAPPING WITH
DRIVEN TOOLS.
