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. Low Maintenance Costs: Enjoy low maintenance costs throughout the machine's service life, thanks to Swiss-quality construction. The Zentroflex M-series center hole grinding machines are designed to deliver high-precision cylindrical grinding in the aviation, automotive, and machinery sectors. Additionally, the Zentroflex M-series is the ideal solution for recovering parts distorted after heat treatment or for reducing cylindrical grinding costs. Contact us for more details.

The workpiece remains stationary, enabling the generation of perfect centre holes. * To clamp cylindrical Workpieces one uses a height adjustable 2 jaw vice which gives three point contact and always coincides with the center of the grinding spindle. * Height-adjustable workpiece centering vice with carbide inserts. Manual adjustment of appropriate workpiece diameter with clamping screw. * Dressing device, mounted on the side of the grinding spindle, stroke approx. 40 mm, for producing a geometrically exact conical form and with oscillation of diamond tool. * Pre-centering device for Workpiece adjustment between centers. * Pneumatic Oil Lubrification of grinding spindle by oil-mist. * Manually adjustable Tailstock with handwheel but without motorized drive.
