Definition of Swiss CNC Machining:
A Swiss-type lathe is unique for its sliding headstock style of lathe machining. This utilizes a standard single-point lathe turning tool placed very close to a guide brushing. By feeding the material through the brushing and past the tool, great rigidity is achieved throughout the turning process.
This allows for the machining of long, slender diameters with high efficiency because the cutting conditions are kept at a maximum regardless of the part length. Chatter and taper are largely eliminated, and in general, very tight tolerances can be held with customary ground barstock. The process lends itself to long and slender parts, which are difficult to support in conventional CNC lathes, as well as short parts, for the same reason – the ability to machine up close and personal with the support.
This method means, in general, all the material must be removed in a single pass. Depths of cut can be larger than one might think practical. The superb rigidity of the Swiss-type process not only makes it possible, but efficient.
This concept of machining was pioneered in Switzerland more than 130 years ago by Dr. Tornos, to produce the many small shafts required by the Swiss watch industry, hence the term “Swiss-Type lathe”.
• Ability to do a great deal in one setup and fast
• Reduces cycle-times and the elimination of secondary handling
• Machines designed to be automatic (capable of running unattended)
• Achieve close tolerances, bearing surface with ease
• Excellent part finishes (compared to conventional lathes)
