Please refer to the machine manufacturer's specifications.
Using the "Centered tapping" cycle, tap a righthand or lefthand thread at the center of the
face surface.
During machining, either the main spindle or counterspindle rotates.You can alter the spindle
speed via the spindle override; feedrate override is not operative.
You can select drilling in one cut, chipbreaking or retraction from the workpiece for stock
removal.
The tool is moved with rapid traverse to the programmed position, allowing for the retraction
plane and safety clearance.
Approach/retraction in one cut
1. The tool drills in the direction of the longitudinal axis at the programmed spindle speed S
or cutting rate V as far as the final drilling depth Z1.
2. The direction of rotation of the spindle reverses and the tool retracts to the safety
clearance at the programmed spindle speed SR or cutting rate VR.
Approach/retraction for stock removal
1. The tool drills in the direction of the longitudinal axis at the programmed spindle speed S
or feedrate V as far as the first infeed depth (maximum infeed depth D).
2. The tool retracts from the workpiece to the safety clearance at spindle speed SR or
cutting rate VR for stock removal.
3. Then the tool is inserted again at spindle speed S or feedrate V and drills to the next
infeed depth.
4. Steps 2 and 3 are repeated until the programmed final drilling depth Z1 is reached.
5. The direction of rotation of the spindle reverses and the tool retracts to the safety
clearance at spindle speed SR or cutting rate VR.
