What is CNC Swiss Precision Machining?
CNC Swiss precision machining, also called Swiss-type or sliding-head machining, uses a sliding headstock lathe to process bar stock. The material is supported by a guide bushing, exposing only the portion being machined. Multi-axis turrets and live tooling allow turning, milling, drilling, threading, and grooving in a single setup, reducing errors and improving efficiency.
This process is ideal for small-diameter, high length-to-diameter ratio parts requiring extremely tight tolerances.
Why Choose Swiss-Type CNC Machining?
- Ultra-High Precision: Guide bushing support minimizes vibration, achieving tolerances down to ±0.0002 in (±0.005 mm).
- Single-Setup Multi-Operation: Multi-axis live tooling enables turning, drilling, milling, threading, and chamfering without removing the part.
- High Efficiency: Continuous feed and multiple simultaneous tools reduce cycle time.
- Superior Surface Finish: Reduced vibration leads to excellent surface quality, often eliminating additional finishing.
- Material Savings: Minimizes scrap, especially for expensive alloys.
- Ideal for Long, Thin Parts: Maintains stability for high length-to-diameter ratio components.
- Handles Difficult Materials: Stainless steel, titanium, nickel alloys, and other engineering materials.
