Conventional CNC Turning vs. Swiss CNC Turning

Computer numerical control (CNC) turning is a machining process that involves the helical removal of material from a workpiece. It is used in producing precise and intricate components, ranging from simple cylindrical shapes to more complex geometries. This process offers exceptional precision, repeatability, and efficiency in creating parts for various industries.

In this article, we will explore the key differences between conventional and Swiss CNC turning, including their respective benefits and applications.

Conventional CNC Turning

Conventional turning involves the rotation of bar stock, while servo-driven motors control the cutting tool’s position. This process ensures precision through accurate tool movements. Commercial metalworking machines typically have standard closed-loop controls, providing high accuracy, speed, and durability.


The following advantages make conventional CNC turning a preferred choice for many manufacturing operations:

  • Precision: Conventional turning offers high precision in machining processes, ensuring accurate and reliable results.
  • Versatility: The method is versatile, accommodating different materials and allowing for the production of intricate components with diverse geometries.
  • Efficiency: With servo-controlled motors and closed-loop controls, the process is efficient and provides fast and consistent machining.
  • Cost-Effectiveness: Conventional turning is often a cost-effective solution for producing high-quality parts, reducing manufacturing costs.
  • Repeatability: The process allows for the creation of high-quality identical parts, which is crucial for mass production and consistent quality.
  • Automation capabilities: The method can be easily integrated into automated manufacturing systems, enhancing overall production efficiency.
  • Ease of programming: CNC turning programs can be created and modified relatively easily, allowing for quick adaptation to changing production requirements.


Here are the common applications of conventional CNC turning:

  • Long parts and small-diameter parts under 0.750 in.
  • Connector components
  • Watch parts
  • Shafts
  • Metal devices and implants
  • Electronic housings
  • Hydraulic components
  • Bushings and bearings
  • Valve components
  • Fluid system parts

Swiss CNC Turning

Swiss turning is a specialized machining process where rotating bar stock is fed through a guide bushing. Its unique feature is that, regardless of the length of the workpiece, the turning tool consistently cuts the stock near the bushing. The design allows the machine to feed the workpiece past the spindle and tool. This makes Swiss turning particularly effective for producing long and slender parts.


While Swiss turning provides mostly similar advantages as conventional turning, the following are its unique benefits:

  • Reduced vibration:The close proximity of the turning tool to the guide bushing minimizes vibration during the machining process.
  • Enhanced tool life:The controlled cutting near the guide bushing helps extend tool life, contributing to cost-effectiveness.
  • Fast production cycles: Swiss-type CNC turning enables rapid and continuous machining, leading to shorter production cycles.
  • Consistent performance: Swiss CNC turning delivers consistent and reliable machining results, ensuring uniform quality across batches.
  • Complex geometries: The process excels in machining intricate part geometries, allowing for the production of sophisticated components.
  • Efficient chip evacuation: The design of Swiss-type machines facilitates efficient chip removal, which prevents chip buildup.
  • Small footprint: Swiss turning machines are often compact. This optimizes floor space in manufacturing facilities.


Listed below are applications of Swiss CNC turning across industries:

  • Dental implants
  • Micro-machining for electronics
  • Orthopedic instruments
  • Optical components
  • Swiss screws and fasteners
  • Sensor housings
  • Prosthetic components
  • Microfluidic devices
  • Miniature gears and gear shafts
  • Micro-valves for medical equipment
