Is a dual-servo tapping machine automatically a rigid-tapping system?
The published platform has servo spindle rotation and servo feed. Confirm the offered control mode, holder requirements, pitch coordination and reversal behavior for the actual setup. The drive description alone is not a specification for every tapping mode.
Can one head tap different thread pitches together?
Do not assume this from the number of servos. Provide a pitch and depth schedule by hole position so the supplier can confirm whether the head, feed and holders support that group or whether separate operations are needed.
Does M0.8–M16 apply to every material and spindle?
No. It is the catalog platform reference, not a promise for every alloy, tap type, depth or simultaneous spindle load. Ask for the proposed application range, tooling and representative-part verification to be stated in the offer.
