Sandvik Coromant’s goal is to drive positive change by advocating sustainability, efficiency, and growth, envisioning a future where innovation flourishes.
Unlike traditional parting-off tools that are aligned with the X-axis of the machine tool, Y-axis parting operates differently. This technique involves rotating the insert pocket by 90 degrees and aligning it with the Y-axis, which offers several advantages.
Upgrading to the CoroCut® QD brings improvements in surface quality, reduces vibration compared to conventional parting off, resulting in less noise, and enables parting off of much larger diameters than currently possible with conventional methods.
Moreover, shifting the resultant load to the strongest section of the blade enhances blade stiffness by six times, allowing for increased feed and longer overhangs without compromising stability. Specifically, the blades have been upgraded to eliminate Y offset, making programming easier and increasing stroke.
Additionally, the blades feature a stop surface that serves two crucial application needs: preventing the blade from being pushed into the adapter and facilitating easier setup. “Traditional parting off involves moving the tool along the X-axis, which puts the cutting force on the weakest part of the blade,” explained Fredrik Selin, Global Product Application Specialist in Turning.
“This can cause bending and instability. By rotating the insert pocket 90 degrees and using the Y-axis, the cutting force is distributed evenly along the entire length of the blade, making it up to 600% stiffer. CoroCut® QDY is designed for parting off in turning centers and multi-task machines with Y-axis capability,” Selin continued.
“It’s great for parting off in sliding head machines, handling large diameters up to 120 millimeters (mm), and reaching long distances between the main and sub chuck. So, when you need to part off or machine deep grooves without compromising on process security or machining efficiency, the enhanced CoroCut QDY® solution is the ideal option.”
