Introduction

The document presents the SPR25 quick-change collet system developed by SCHAUBLIN S.A., designed for efficient tool re-sharpening operations requiring multiple collet changes throughout the day.

Key Features

• Automatic or manual collet change capability.
• Reduction of setup time by 75%, significantly improving operational efficiency.
• High repeatability of radial runout, ensuring precision.
• Clamping range from 3.0 mm to 21.0 mm, accommodating various tool sizes.

System Adaptability

The SPR25 system can be integrated with any grinding machine that supports automatic collet clamping, enhancing versatility across different equipment.

Operating Principle

The collet change is facilitated through a clip-on mechanism:

• Collets can be manually pushed in or extracted using a dedicated extraction tool.
• Automatic extraction is possible by adapting robotic fingers to the collet's extraction collar.

The collet design has been completely redesigned to optimize performance:

• Threadless design enables the clip-on system.
• A keyway entry ensures precise angular orientation of the collet.
• A weakened taper section improves rigidity and clamping force.
• The extraction collar allows for rapid collet changes.
