In the not so distant past, when you needed to work on small and complex parts, using a Swiss Computer Numerical Control (CNC) machine was out of the question. After all, the machine was believed to be suitable for use only on bigger and longer work pieces.
Things have changed, however. Today, Swiss turning machines are now used extensively on small workpieces to achieve the desired results.
Swiss-Type Turning Machines
Conventional lathes work with a headstock. Unlike conventional lathes, however, a Swiss CNC machine does not have a fixed headstock. Its headstock can be made to move around, depending on the user’s particular needs.
The biggest advantage of a movable headstock is that it supports and works particularly well with small parts. The CNC machine guides the small workpiece and eliminates deflections, thus giving the desired precise results.
How Small Are Small Work Pieces?
You can easily tell whether your workpieces are small or not just by giving them a once-over. As a rule, if no two pieces in the lot are bigger than the size of your palm, then they are considered small. To be more specific, they should not be more than 1.25” in diameter.
The Machine’s Core
The guide bushing is what makes a Swiss turning machine work very well with particularly small parts. It may be considered as the core, or the heart and soul, of the machine. Because of the movable headstock and the guide bushing, the machine is able to steer the workpieces in the desired direction, keeping them in place, while the machine holds them tightly.
To put it plainly, small work pieces are in good hands with a Swiss CNC machine. There is no doubt that the machine can handle small parts well. With the movable headstock, a higher level of precision is achieved. The cycle time is likewise reduced in the process.
