Normally the tapping attachments type SWITCH-MASTER ® are made for the production of right-hand threads. However, on request the attachment can be produced also for left-hand threads. The turning direction of the machine spindle remains right-turning in both cases.
For the use of the tapping attachment, a stop block is needed for the following functions:
The stop block is normally ﬁ tted individually to the customer‘s machine before shipping of the attachment.
The connection to the machine spindle is a cylinder shank Ø 25 acc. to DIN 1835 B+E; the use of the adapter shanks is a fast and economically efﬁ cient way of guaranteeing the compatibility with all the usual spindle adaptions. Producing range is M4 - M12. Maximum permissible speed: 3000 rpm On the machine side, compressed air (6 +1 -0,5 bar) is needed as auxiliary energy for the change of direction of rotation.
Tool locking is executed via collets of size ER 16 acc. to DIN ISO 15488.
Owing to the better torque transmission, we recommend the use of collets with integrated square (type ER16-GB).
The attachments are designed for the use with internal coolant-lubricant supply (IKZ) up to 50 bar (700psi) coolant-lubricant pressure.
