A Swiss Lathe is a type of lathe whereby the holding mechanism or collet is recessed behind the guide bushing. The Swiss lathes are also commonly known as Swiss screw machines, Swiss automatic lathes or Swiss turning centers. The Swiss lathe differ from the traditional lathes in the way that the holding mechanism or collet that holds a bar stock will not be exposed directly to the lathe bed and the tooling. This particular configuration provides this specific machine tool a number of benefits over the traditional type lathes.Get more news about Precision Swiss Lathe,you can vist our website!

The advantages of the Swiss lathe over traditional lathes are largely due to the fact that it utilizes guide bushing. The guide bushing purpose is to offer an additional support to stock material when the part is machined or turned. This guide bushing is fitted closely yet not tightly to surround the bar-stock materials.
The support of this bar-stock material means that the functions of the guide bushing act in a similar fashion as steady-rest does on carriages of traditional lathes.

The Swiss-style lathes typically hold a better tolerance on the parts as turning operations will be conducted closely to the guide bushing.
The guide bushing offers rigidity to turned parts due to the fact that a very small amount of the stock will be exposed once they have left the bushing and until such stage that the turning tools have been engaged.
The guide bushing offers significant rigidity to the stock and these machine types are significantly well-adapted to holding a tight tolerance.

Another benefit of the abilities of the Swiss-style lathe is that they have the abilities to turn the small-diameter parts. Alternatively, they can turn parts that have a larger length-to-diameter ratio. Chatter of tools is also minimized due to the guide or tool bushing position.

How A Swiss Lathe Operates?
In conventional lathes which feature fixed headstocks, a work piece will be held in the collet or chuck which will either extend into the enclosure of the machine in the form of a cantilever. The other way is that it will be supported on the one end with a tailstock. The distinguishing factors of the Swiss machines to other types are the fact that the headstock moves.

This means that the bar-stock will pass through the chucking collet positioned in the area of the headstock that it will be clamped onto.
This bar then emerges in the tooling-area through the guide bushing that locates this bar radially while machining. This headstock then moves in a precise back-and-forth motion in a z-direction while taking the bar along with it.

Turning tools that are carried on the gang slides will make contact with this bar in close proximity to the guide bushing. The bar’s motion offers the feed required for the cutting action. The gang slides will carry the holders for the fixed single-point tools or any of the other tools and can even support the live tooling. Many of these machines use back-working tool stations and secondary spindles and in some cases a turret or more that is able to carry additional tools.
