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. Contact us for more details.
