Benefits:

Sub-micron Precision: Achieve sub-micron (< 1 µm) precision in grinding thanks to Swiss engineering and a robust machine design.

Sustainable Reliability: Ensure reliable and sustainable processing.

Non-Stop Production: Achieve continuous production with robotic arm feeding, automatic dressing, and automatic compensation features, eliminating the need for constant operator oversight.

Quirlig Grinding Technique: Experience an optimized grinding process with the Quirlig Grinding Technique. Properly ground center holes that have cross-hatched grinding pattern. The cross-hatched grinding pattern ensures that oil is retained when the workpiece is placed between the centers during the cylindrical grinding process, creating a micro oil layer. The micro oil layer prevents unwanted "dry running" during cylindrical grinding.

Easy to Use Complete-CNC Control Panel: Utilize a full CNC control panel that allows you to control all axes of the machine, manage robotic feeding, and perform automatic dressing with the Beckhoff control panel. Easily save all grinding programs and monitor machine working times, efficiency, and errors.

Industry 4.0: Fully compatible with Industry 4.0 applications, thanks to the Beckhoff control panel.

Low Maintenance Costs: Enjoy low maintenance costs throughout the machine's service life, thanks to Swiss-quality construction.

The Zentroflex A-series center hole grinding machines are designed to deliver high-precision cylindrical grinding in the aviation, automotive, and machinery sectors for mass-production. Additionally, the Zentroflex A-series is the ideal solution for recovering parts distorted after heat treatment or for reducing cylindrical grinding costs.

With 6-Axis robot arm and servo motors on all axes of the machine, Zentroflex A-series center hole grinding machines operate completely autonomously. All loading and unloading operations are performed by the robot arm. All axis movements of the machine are also performed autonomously with servo motors. Cone dressing and compensation are also performed automatically. All movements and measurements of the machine are performed from the CNC control panel.
