This blog post will delve into the intricacies of Swiss machining, exploring its advantages, capabilities, applications, and the reasons why it has become an indispensable process in modern manufacturing.
The Evolution of Swiss Machining
Swiss machining, also known as Swiss-style turning, originated in the 19th century in Switzerland's watchmaking industry. The need for producing small, precise parts for watches led to the development of this unique machining technique. Over time, Swiss machining has evolved from its manual roots to become a highly automated, computer-controlled process that finds applications far beyond watchmaking.
Key Milestones in Swiss Machining History:
- 1870s: Development of the first Swiss-type lathes
- 1960s: Introduction of numerical control (NC) to Swiss-type machines
- 1970s-1980s: Adoption of computer numerical control (CNC) technology
- 1990s-Present: Integration of multi-axis capabilities and advanced automation
The Swiss Advantage
Swiss-type CNC lathes, like our Marubeni Citizen-Cincom machines, offer several key advantages that set them apart from conventional machining methods:
