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.
