Overview
With the new System 208, Gühring introduces a grooving system developed for sliding headstock lathes. The system's specific geometry, high interchangeability and documented service-life benefits address the requirements for machining complex micro-turned parts.

Compact design for confined spaces
Sliding headstock lathes often operate in very confined spaces. The rhombic, ground indexable insert with two cutting edges is designed for precise use even on small machines with bar feeders. With a maximum grooving depth of 8 mm, System 208 covers operations from parting-off to grooving and longitudinal turning. Field trials reported up to 30% longer tool life versus competitors, shorter cycle times and more stable processes, reducing tool changes and part costs while supporting stable series production.

High process reliability thanks to precise interface
A central feature of System 208 is its high-precision interface with a changeover accuracy of ±0.015 mm, ensuring exact repositioning of cutting edges after each insert change. The newly developed double-sided Torx-Plus clamping screw enables quick insert changes directly in the machine, saving operating time and simplifying handling.

Focus on customer benefits
System 208 provides advantages across several sectors:

• medical sector: precise machining of intricate components such as implants and instruments
• electronics & robotics: high process reliability for small batches and high-volume production
• connector technology: reliable machining of demanding materials

The system increases machine availability, extends tool runtime and reduces total cost per component.

What the grooving programme consists of
The System 208 programme includes:

• Precisely ground indexable inserts with nanoA coating in five geometry variants (GE, GP, GR, GZ neutral & GZ R/L) for grooving depths up to 8 mm
• Tool holders in 10×10, 12×12, 16×16 mm, available right/left, with or without internal coolant (IC)
• New Torx-Plus clamping screw for quick handling

Conclusion — How you benefit from System 208
System 208 is tailored to sliding headstock turning technology, addressing limited space, high precision and process reliability while improving manufacturing cost-effectiveness.
