S3D Synchro

Synchro tapping chuck

APPLICATION

Application: Automotive, general Mechanical Engineering, Renewable

Machine type: machining centres, CNC-turning and special purpose machines with synchronized feed
for the tapping operation

Features

Minimum length compensation in compression and tension direction
Ball bearing mounted (i.e. torque independent) suspension
Suitable for internal coolant supply up to 80 bar
Suitable for taps and thread formers
Suitable for right-hand and left-hand threads
Optimized spring-damper technology (± 0.5mm)
3D Synchro completely encapsulated function chamber (washable up to 80°C)
Optimized seal (comparable to IP68)
100% SCK-kompatibel

Advantage

Reduction of the pressure on the thread fl anks Compensation of synchronization errors
Compensation of synchronization errors
Higher process stability
Longer tap life
Better thread quality

Tool presetting via axial adjustment screw possible from both sides
(screw is not included in the scope of delivery)

Best application

You can use our 3D-Synchro chuck as a collet chuck
for driven tool holders as well as for direct clamping
in machine spindles.

maintaining thread quality and tolerance. With the standard collet chuck, the cutting speed could not be increased, otherwise the threads would no longer be within tolerance.}

The service life can be mor than

The elastomers used are dimensionally stable and resistant to all
coolants/lubricants. Due to the defi ned length compensation,
plastic deformation of the damping elements is excluded.

This results in consistent cutting behavior over the entire life of the tool.

Reduction of the load

Higher process stability - better thread quality - longer service life

The latest generation S3D- Synchro chuck has been adapted to the current market requirements.
Tool presetting is possible from the machine side and the tool side, the lubricant feed-through
has been optimized, thus ensuring a leakage-free transfer to the tap.

The length compensation on compression and tension (e.g. +/- 0.5 mm), as well as the damping
in the direction of rotation compensate for the smallest synchronization errors and position deviations.
This reduces the pressure on the on the thread fl anks of the tool is reduced and the required cutting torque is minimized.

The patented spring-damper technology reduces stresses during tapping and forming
