<span style="vertical-align: inherit;">Reducerad cykeltid, förbättrad ytkvalitet på komponenterna samt en stabilare bearbetning är några av fördelarna med svarvning med Y-axeln.</span>

<span style="vertical-align: inherit;">Recent years have seen major changes in the field of turning, with new innovations such as PrimeTurning™ in all directions, non-linear turning and interpolating turning. "You could say that these advances, together with progressive capabilities in modern machines and CAM software, have laid the foundation for the new Y-axis turning method," says Staffan Lundström, Product Manager responsible for turning at Sandvik Coromant. "With these tools and this method in place, we look forward to exploring the possibilities this method can offer our customers."</span>

<span style="vertical-align: inherit;">So how does Y-axis turning work? Just as the name suggests, the new method uses the Y-axis, and all three axes are used simultaneously during processing. The tool rotates around its own center, the insert is positioned for machining in the YZ plane, and the milling spindle axis interpolates during turning. In this way, detailed shapes can be processed with a single tool.</span>

<span style="vertical-align: inherit;">There are many advantages to turning with the Y axis. The ability to process several parts with a single tool allows you to reduce the cycle time. The fact that no tool changes are required also minimizes the risk of "transitions", i.e. roughness on adjacent surfaces. The main cutting forces are directed towards the machine spindle, which improves stability and reduces the risk of vibration. A constant entry angle greatly improves chip control and makes easier to avoid chip jamming.</span>

<span style="vertical-align: inherit;">Two new tools have been developed for use in Y-axis turning. The new CoroTurn® Prime variant is well suited for shanks, flanges and components with hollow wedges. The twin tool CoroPlex® YT with CoroTurn® TR profile insert and CoroTurn® 107 round insert with rail interface can be advantageously used for components with pockets and cavities.</span>

<span style="vertical-align: inherit;">In summary, it can be said that turning with the Y-axis is a method of simultaneous 3-axis turning with interpolation of the milling spindle axis. The new tools can also be used in "static mode" with a locked spindle, for flexible 2-axis turning and with fast cutting indexing. The method is suitable for all materials and requires a multifunction machine with options for interpolation of the milling spindle axis during turning.</span>
