CNC Sliding Head Lathes, also commonly known as Swiss Auto lathes, were first designed for producing precision watch parts and other mill-turn components within exceptionally close geometric tolerances.
As a modern type of machine tool controlled by computer numerical programming, sliding head machinery is capable of performing machining operations with extreme accuracy.
Sliding head lathes allow the workpiece to move in the Z-axis while the tool remains stationary. This is unlike traditional lathes where the workpiece remains in position while the tools move around it. The benefit of this is increased precision and reduced process time.
The specialist technology behind sliding head lathes involves a bar being fed through the CNC machine's headstock and being grasped by a collet, with the option of an additional support via a guide bush arrangement. The combination of the cutting tools in close proximity to the workholding operation allows for a more efficient process which ensures maximum stability and accuracy.
The utilisation of the secondary/sub spindle and back-working tool post, paired with a CNC control system, allows for a single comprehensive operation. This eliminates the requirement for operator intervention of manually changing each component between operations.
Star sliding head technology can suit various milled and turned parts up to a maximum diameter of 42mm, and our machines can be configured for producing miniature prismatic components or shafts in excess of 2m.
A significant benefit of sliding head technology is the reduction in cycle times compared to other technologies such as fixed head machining. The cutting tools in a sliding head machine are positioned very close to the workpiece which reduces non-cutting 'idle' time, while the sub-spindle allows operations to be overlapped to further reduce cycle time.
The flexibility of sliding head machines typically enables components to be produced in one-hit which removes the need for additional operations, while the quick set-up time makes short runs easy and efficient. Star machines also have the capability to operate unattended overnight "lights-out" which significantly reduces process times and cost per part.
Star GB is the only company who are solely dedicated to sliding head technology. Star machines are built at the ultra-modern Kikugawa plant in Japan and are renowned for their outstanding build quality, long-term reliability and exceptional performance.
Star Swiss Auto lathes are easy to set-up, simple to program and cheaper to run than most competitors due to the lower power consumption.
