China Swiss Lathe Product Introduction Swiss CNC Machine is different from turning centers. They work by bringing the workpiece to the tool, rather than letting the tool get close to the workpiece.They use bar chucks to hold and move the bar, and use a guide sleeve to support the bar. The tool is fixed on the Z axis, and the chuck pushes the bar through the guide sleeve and passes the tool. The guide sleeve provides support for the bar material very close to the cutting point, so that slender workpieces can be processed without deformation or vibration.http://www.swisstypelathes.com/swis-lathe/
