CNC Swiss-type machining centers, a sliding headstock automatic lathe that has become increasingly popular in recent years, offer versatile capabilities, including:
- Turning external diameters, cones, arcs, and curved surfaces
- Machining internal and external threads
- Milling slots, slotting, and spiral grooves
- Drilling and boring holes
- Tapping holes and engraving
- Knurling
These machines typically handle materials ranging from 2mm to 20mm in diameter, though larger models are available. Per esempio, the Japanese brand Nomura Swiss-type CNC machines introduced by RapidEfficient can process materials with diameters up to 25mm.
Swiss-type machines can also process irregularly shaped profiles such as hexagonal, piazza, and triangular bars. They offer:
- High precision
- Wide applications
- Exceptional versatility
They are ideal for high-volume, high-variety, and high-precision machining of long, thin shafts and small, complex parts. Industries that benefit include:
- Medico
- Aviation and aerospace
- Military
- Automotive and motorcycles
- Communications
- Refrigeration and optics
- Home appliances and electronics
- Microelectronics, watches, and mobile phones
Improved Efficiency and Precision
CNC Swiss-type machining centers represent a qualitative leap in efficiency and accuracy compared to conventional CNC lathes.
- Dual-row tooling significantly shortens cycle time
- Reductions are achieved through:
- Tool shortening
- Multi-tool station overlap
- Thread chip effective axis movement overlap
- Direct spindle machining
The tool always operates between the spindle and the workpiece, ensuring consistent machining accuracy.
Main Advantages of CNC Swiss-type Machining
- Shortened Manufacturing Process Chain
- Milling and turning can complete all or most steps in a single operation.
- Significantly reduces the overall production process chain.
- Reduced Clamping, Improved Accuracy
- Fewer clamping times minimize errors caused by datum conversion.
- Lower Production Costs, Smaller Footprint
- Although unit machine cost is high, the process chain reduces the need for additional equipment, infissi, and workshop space.
- Lowers equipment maintenance and management costs.
- Effectively reduces total fixed asset investment.
