1 Application range, safety instructions and technical data
1.1 Application range, determined use
The collet holders type Softsynchro®/MMS are used on CNC machining centres with
synchronous control working with minimum-quantity lubrication (MQL). They are
intended for clamping of taps/cold-forming taps for thread production.
The integrated minimal length compensation on tension and compression
compensates arising minimal pitch differences between synchronous spindle and
tap/cold forming tap which would lead to high thread flank friction forces. An eventual
increase of the axial force during the thread producing cycle is reduced to a
minimum. The resulting advantages are:
-No mis-cutting of the threads
-Optimised tool life of the tap/cold-forming tap
The collet holders Softsynchro®/MMS are used with collets and sealing disks in the
clamping nut with tap/cold-forming tap provided with a coolant channel for minimum-
quantity lubrication.
The guiding of the aerosol mixture through the center of the collet holder up to the
coolant channel is designed for flow-optimized and is guaranteed by a spring-
mounted MQL tube.
Normally the collet holders are equipped with the following shank:
Hollow taper shank according to DIN 69893-HSK-A, suitable as form C by using
an adapter.
The cutting range of each type is indicated in table 1, page 7
The tap/cold-forming tap is locked via the collets according to DIN ISO 6499.
The collets must be chosen depending on the used type and used tap/cold-forming
tap, for more information please refer to chapter 2.5, page 11.
The collet holders type Softsynchro®/MMS are specially made for minimum-quantity
lubrication, for more information please refer to chapter 1.2, page 5
The non-determined use exempts the manufacturer from any liability.

Operating instruction edition: 01.02.2017 5
1.2 Specifications
Features of the collet holders type Softsynchro®/MMS are:
Small and compact overhang
Minimum-quantity lubrication (MQL):
Target-oriented, flow-optimized guidance of the MQL aerosol through the
center of the collet holder up to the tap/cold-forming tap
Environmentally sound lubrication
The high cutting values for wet machining may be kept.
Reduction of the machine hour rate by omission of purchase and maintenance
of expensive filter devices and disposal of the emulsions.

1.3 Safety instructions and hints
For all works, i.e. putting into operation, production and maintenance, please observe
the details given in the operating instructions.
All relevant safety regulations as well as local instructions are to be observed when
working with the collet holders.
Below please find some basic rules:
Attention
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 work piece.
Keep the tool adaption clean.
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!
1.4 Proprietary rights
The entire contents of these operating instructions are subject to German proprietary
rights legislation.
Any form of multiplication, processing, broadcasting, passing on to third parties - also
in the form of extracts - and any kind of use outside the boundaries of proprietary
rights requires the written consent of EMUGE GmbH&Co.KG.

Note
The maximum air pressure at the entry to the holder is up to 6 bar.
Collet holders with shank according to DIN 69893-HSK-A have an integrated coolant-
lubricant tube which must not be disassembled, otherwise the function of the MQL
transfer is no longer guaranteed!
The collet holders are available for 1-channel and 2-channel MQL-systems and in
design with shank HSK-C for 1-channel MQL-systems.
Further outer dimensions may be taken from the EMUGE main catalogue.

2 Putting the collet holders into operation
2.1 Unpacking
Take the collet holder from the packing
Clean the collet holder with a duster to remove any conservation oil
Note
Do not use any aggressive solvents.
Do not use fibrous materials i.e. steel wool.
The collet holder is now ready for operation.
2.2 First putting into operation
The collet holders are inserted into the machine manually or - if provided - by the tool
exchanger.
Attention
The exchange of the collet holder must not be executed while the machine spindle
rotates!
Only use tool shanks and tightening bolts suitable for the specific machine.
Make sure the tool is correctly clamped.
Otherwise: Risk of accident by spinning of the tool!
Please see also the indications in the operating instruction of your machine tool!
The collet holders with hollow taper shank, DIN69893-HSK-A, are already
equipped with a coolant-lubricant tube. This coolant-lubricant tube may not be
removed, as it contains the mechanism for the minimum-quantity lubrication.

2.3 Re-putting into operation
If the collet holder is back into operation as described in chapter 4, page 15, please
go through the following steps:
- Clean the collet holder with a duster to remove any conservation oil
Note
Do not use any aggressive solvents.
Do not use fibrous materials i.e. steel wool.
- If necessary, prepare the collet holder as described in chapter 2.2, page 8

2.4 Sealing disks for clamping nuts
2.4.1 Application
The sealing disks are inserted into the clamping nuts for producing threads with
minimum quantity lubrication. The sealing disks additionally avoid the penetration of
dirt and chips into the collet slots. We do recommend the use of sealing disks.
Note
Normally a nut for sealing disks is part of the delivery. The sealing disk hasto be
ordered separately, suitable for clamping nut and clamping diameter.
2.4.2 Assembly instruction for sealing disks into clamping nuts
1. Screw the clamping nut off
2. Insert the sealing disk into the
clamping nut as shown on
picture.
Push the sealing disk forward
into the clamping nut until you
clearly hear the engagement.
The sealing disk must be flush
at the front with the clamping
nut

2.5 Collets
2.5.1 Application
The adaptation of the tap/cold-forming tap is executed via collets type ER and/or
ER/GB. With collets type ER the tap/cold forming tap is centered and clamped via the
shank diameter. With collets type ER/GB the torque - arising during the thread
producing operation - is additionally transferred via the square integrated in the collet.
Note
Owing to the better torque transmission, we recommend the use of collets type
ER/GB.
The collet sizes for the according collet holders may be taken from table 1, page 7.
The clamping diameter is indicated by the tap/cold-forming tap used.
The minimum-quantity lubrication is only guaranteed in connection with a tap/cold-
forming tap provided with coolant channel made for minimum-quantity lubrication.
2.5.2 Assembly instruction for the collets and taps/cold-forming taps
1. Insert collet into the clamping nut,
tilt collet.
The groove of the collet must
engage in the eccentric ring of the
clamping nut at the marked position.
Tilt collet in opposite direction until it
clearly engages
→Collet is flush with the clamping
nut and/or the sealing disk.
2. Screw the collet with the engaged
clamping nut manually onto the
thread of the collet holder

3. Insert tap/cold-forming tap
Attention
If collet and tool are provided with a square, the tool must be turned into position in
order to be inserted into the square of the collet.
4. Tighten the clamping nut with the
appropriate wrench.
The tightening torques of the
clamping nut may be taken from
table 3, page 13
Attention
In order to avoid damaging the collet holder it is necessary to support the spindle
with the open-ended spannerwhen tightening the clamping nut with the
wrench.
See tool set table 2, page 13
As an alternative to the above mentioned wrench
the assembly device, article number F315199.02,
can be used.
