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.

Cost Efficiency & High Productivity: Benefit from lower production costs and high productivity due to a short grinding process and reduced production times for subsequent processes (cylindrical grinding).

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 CNC Control Panel: Benefit from very simple operation and grinding program recording with the Beckhoff control panel and Z-axis servo movement.

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

Z-Axis movement is provided by servo motor in CNC form. The part is loaded-unloaded and clamped manually. Settings are made from CNC control panel and grinding is started by pressing the start button. No other manual setting or control is made during grinding.
