Application range, safety instructions and technical data

1.1 Application range, determined use
The collet holders type Speedsynchro ® Mini are used on CNC-machining centers with synchronous control. They are intended for clamping of taps/cold-forming taps for thread production. Normally the Speedsynchro ® Mini are equipped with the following shank:  BT 30 (DIN) ISO 7388-2 JD Applicable for cutting range M1 – M6, please refer to Table 1, page 7. The tap/cold-forming tap is locked via the collets according to DIN ISO 15488. The collets must be chosen depending on the used type and used tap/cold-forming tap, for more information please refer to chapter 2.6, page 15. The collet holders type Speedsynchro ® Mini are designed for coolant-lubricant pressure up to 70 bar. For correct use, the Speedsynchro ® Mini must be secured against twisting in the machine spindle. This requires a stop fixture adapted to the machine-side locking block. For further details, please refer to chapter 2.2 page 8.
The non-determined use exempts the manufacturer from any liability.
1.2 Specifications
Further characteristics of the Speedsynchro ® Mini:

• The Speedsynchro Mini uses an integrated gear ratio of 1:4,412. (This enables the machine spindle to be operated in a lower speed range, thus saving energy.)
• The integrated minimal length compensation on tension and compression compensates arising minimal pitch differences between synchronous spindle and tap/cold forming tap possibly leading to high thread flank friction forces. A possible increase of axial force during the thread producing cycle is reduced to a minimum. The resulting advantages are: – no mis-cutting of the threads – optimized tool life of tap/cold-forming tap
• The Speedsynchro ® Mini has an NFC-Modul (NFC = Near Field Communication) with integrated electronics. This takes and stores the operating data. An NFCenabled smartphone is required to read out the data (not included in the delivery). For further details please refer to chapter 3, page 18.
• Simple programming as synchronous cycle with feed programme adapted to the transmission ratio.
• The reversal of the tap/cold-forming tap is done by the machine spindle: – no switching components in the Speedsynchro ® Mini – low wear and longer maintenance intervals
• High changing speeds are possible due to the low weight (< 2 kg) and the compact design.

1.3 Safety instructions and hints
For all works, i.e. putting into operation, production or maintenance, please observe the details given in the operating instruction.
All relevant safety regulations as well as local instructions are to be observed when working.
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 adaptation 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!

Note
For series use, please observe the programming instructions, chapter 2.3, page 12.
2.3 Programming notes
The transmission ratio of the Speedsynchro ® Mini is 1:4,412.
This results in the following programming guidelines.

• Feed f
  f = P x 4,412
  f = Feed [mm/rev.] P = Pitch of threading tool [mm]

• Rotational speed n of the machine spindle for the desired tool speed
  nMSP = nTOOL / 4,412
  nMSP = Rotational speed of machine spindle [rpm] nTOOL = Rotational speed of threading tool [rpm]

Attention
The maximum speed at the machine spindle is: nMSP = 2.700 rpm
The maximum speed at the tool is: nTOOL = 11.912 rpm
Example: thread M2 / pitch P = 0,4 mm:
Desired rotational speed of threading tool:
nTOOL = 11.000 rpm
Required rotational speed of machine spindle:
nMSP = 11.000 rpm / 4,412 = 2.490 rpm
Required feed f, per revolution of the machine spindle:
f = 0,4 x 4,412 mm/rev. = 1,765 mm/rev.
Attention
When working with internal coolant supply:
The maximum coolant-lubricant pressure is 70 bar.
The internal coolant is supplied centrally through the spindle.

2.5 Sealing disk / cooling disk
2.5.1 Application
The sealing disks or cooling disks are inserted into the clamping nuts for producing threads with internal coolant supply. The sealing disks respectively the cooling disks additionally avoid the penetration of dirt and chips into the collet slots. We do recommend the use of sealing disks or cooling disks. In contrast to the sealing disks, the cooling disks guide the coolant directly along the tool.
Note Normally a clamping nut for sealing disks/cooling disks is part of the delivery. The sealing disk or cooling disk has to be ordered separately, suitable for clamping nut and clamping diameter!
2.5.2 Assembly of the sealing disk or cooling disk

1. Screw off the clamping nut
2. Insert sealing disk/cooling disk into clamping nut as shown on picture. Push sealing disk/cooling disk forward into clamping nut until you clearly hear the engagement. The sealing disk must be flush at the front with the clamping nut.

2.6 Collets
2.6.1 Application
The adaptation of the tap/cold-forming tap is done 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 Due to the better torque transmission we recommend the use of collets type ER/GB. The collet sizes for the according Speedsynchro Mini may be taken from Table 1, page 7. The clamping diameter is specified by the tap /cold-forming tap used.
2.6.2 Assembly of the collet

1. Insert collet into 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 clamping nut and/or sealing disk.
1. Screw clamping nut with engaged collet onto the thread of the collet holder.
2.7 Assembly of the tap/cold-forming tap

1. Insert tap/cold-forming tap 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!
2. Tighten clamping nut with appropriate wrench.
   Attention
   In order to avoid damaging of Speedsynchro ® Mini parts, it is necessary during the tightening of the clamping nut via wrench to support with open- ended spanner 2. As an alternative to the openended spanner the assembly device F3720900 can be used.

Note
Wrenches are part of the delivery.
To adjust the correct torque (please see table 3), we recommend to use a torque wrench.
Table 3: Tightening torques for clamping nuts

Data valid for the use of ER-GB collets.
The maximum tightening torque must not be more than 25% above the recommended values. Higher torque may result in the damage of the collet holder.
