Synchronous tailstock

Product catalog summary

Overview: The document discusses the features and benefits of a synchronized tailstock drive used in grinding machines, specifically within the UNITED GRINDING Group. This technology enhances flexibility and productivity by synchronizing the tailstock with the workhead, allowing for increased drive torque and improved machining accuracy.

Synchronous Tailstock Features:

The tailstock is synchronously driven to the workhead, increasing drive torque through the friction of the centers in the workpiece.
Allows for complete machining in a single clamping, enhancing form and position accuracy.
Facilitates easy setup for automated workpiece changes.
Programmable stroke of 120 mm and reference length definition enable efficient grinding of part families with varying workpiece lengths.
Axial positioning via servomotor with an NC drive ensures high position repeatability.
Individually controllable positioning, center-search, and clamping speeds.
Programmable clamping force with exchangeable springs for progressive adjustment.
Includes an air lift for easy movement.

Integration and Certification:

The synchronous tailstock is integrated into the StuderWIN operating software.
Certified under ISO 9001 and VDA6.4 standards.
Swiss-made by Fritz Studer AG.

Technical Data:

Compatible with STUDER machines S22, S33, S31, S41.
Height of centers: 175 mm (225 mm with intermediate plate).
Max workpiece weight: 80 kg.
Spindle drive max: 1.6 kW.
Fitting taper: MT4.
Stroke (W-axis): 120 mm.
Travel speed: 0–6 m/min.
Clamping principle: Electromechanical with springs.
Clamping force: 250–4000 N, adjustable progressively.
Spindle speed: 1-1500 rpm, optionally with motor brake.
Fine adjustment for cylindricity corrections: ± 80 μm.

Usage and Limitations:

Can be used with stationary centers, rotating centers, and spring collets.
Usable distance between centers is reduced depending on machine type and wheelhead variant.
Mounting of dressers on the tailstock is not possible.

The tailstock, which is synchronously driven to the workhead, increases the drive torque using the friction of the centres in the workpiece. In the simplest case two standard centers are sufficient, whether in conventional or high-speed grinding at 140 m/s. The omission of an additional workpiece drive facilitates complete machining of the workpiece in a single clamping. This increases the form and position accuracy on the ground workpiece. Automated workpiece changes are easy to set up. Thanks to the programmable stroke of 120 mm and the definition of reference lengths, part families with a...
