Sandvik Coromant, a cutting tool and tooling system specialist, has introduced a new method for turning complex shapes and pockets with just one tool. The Y-axis turning technique offers several benefits, including reduced cycle time, the improved surface quality of components, and stable machining.
In recent years, there has been a significant development in the area of turning, with new innovations such as all-directional PrimeTurning™, interpolation turning, and non-linear turning. These advancements, together with progressive capabilities in modern machines and CAM software, have paved the way for the new Y-axis turning method. Cutting tool and tooling system specialist, Sandvik Coromant, has introduced this new method for turning complicated shapes and pockets with only one tool. The Y-axis turning technique offers numerous benefits, including reduced cycle time, improved component surface quality, and more stable machining. In this article, we will explore Y-axis turning in more detail and the tools that Sandvik Coromant has developed to support this new method.
The development of Y-axis turning is a result of advancements in modern machines and CAM software, which have paved the way for innovative turning methods such as all-directional PrimeTurning™, interpolation turning, and non-linear turning. Sandvik Coromant’s Product Manager Turning, Staffan Lundström, believes that Y-axis turning will open up new possibilities for their customers.
Y-axis turning works by using all three axes simultaneously, with the tool rotating around its centre, the insert placed for machining in the Y-Z plane, and the milling spindle axis interpolating during turning. This allows for intricate shapes to be machined with just one tool.
Y-axis turning offers numerous benefits. By using only one tool, cycle time is reduced, and the risk of irregularities between adjacent surfaces is minimized. Main cutting forces are directed into the machine spindle, improving stability and reducing the risk of vibrations. The constant entering angle also enhances chip control and makes it easier to avoid chip jamming.
To support the Y-axis turning method, Sandvik Coromant has developed two new tools. The CoroTurn® Prime variant is suitable for shafts, flanges, and components with undercuts. The CoroPlex® YT twin-tool features CoroTurn® TR profiling inserts and CoroTurn® 107 round inserts with rail interface, making it suitable for components with pockets and cavities. Y-axis turning is a simultaneous 3-axis turning method that interpolates the milling spindle axis. This method is suitable for all materials and requires a multi-task machine with options that allow for interpolation of the milling spindle axis during turning. Additionally, the new tools can be used in static mode with a locked spindle for flexible 2-axis turning with fast insert indexing.
