Application of the adaptors:
• Adaptation of EMUGE Elastic dies.
The elastic die is hold by the elastic automatic sleeve and pressed against the
plane surface of the holder. After tightening, the elastic automatic sleeve is locked
with the check nut. Assembly and adjustment details may be found in chapter 2.2,
page 6.
• These adaptors are designed to be used in the following quick-change tap
holders. EMUGE types:
KSN KSN/HD KSN/IKZZ/MMS
SFM SFM/NP SFM-L SFM-L-DZ
• Cutting of external threads.
The max. thread depth to be cut depends on the thread size and the sleeve size
used. These values are listed in Table 1, page 5.
• Cutting of right- and left-hand threads.
The adaptor size is defined by the tap holder size used.
The required sleeve size is defined by the cutting range.

For all works, ie putting into operation, production, maintenance please observe the
details given in the operating instructions.
All relevant safety regulations as well as local instructions are to be observed .
Below please find some basic rules:
- Please wear gloves during tool change to avoid injury.
- Basically change the tool yourself to avoid the sudden start of the spindle
caused by mis-operating.
- Hold the tool when loosening the tool clamping to avoid it falling down
and damaging the tool and the workpiece.
- There are maximum values for cutting speeds and feeds for every kind of
machining. Please observe such data.
- Please observe the maximum tool dimensions.
- Furthermore, the instructions of the tool manufacturers are valid!

The tool receives an elastic effect by the radial slots in the elastic die. This is why the
tightening force of the elastic automatic sleeves influences the tolerance range of the
bolt pitch dimension. By careful adjustment the required tolerance range may be
reached.
After the clamping operation the first 2 – 3 cut bolts should be checked to
their pitch diameter. If the dimension is not correct: Mark position of the
automatic sleeve, reduce locking by detaching the check nut, adjust the
sleeve and lock again using the check nut.
,PSRUWDQW
Before every adjustment, the clamping of the elastic-die must be completely
detached!
For further information on assembly and adjustment, please refer to our brochure
„EMUGE Elastic dies“.
