Computer numerical control (CNC) Swiss machining offers exceptional precision in the production of small mechanical parts. CNC Swiss machining employs multiple sets of tooling that operate in succession or simultaneously on a rotating workpiece. A guide bushing offers excellent stability and ensures that only the part of the workpiece being machined gets exposed, further enhancing the accuracy of machining operations by mitigating deflections. These capabilities make CNC Swiss machining an ideal process for small, tight-tolerance parts.
At dti EXACT™, our multi-spindle Swiss machining centers can accommodate high volumes of parts up to 1.25 inches in diameter and 8 inches in length. Because of its moveable headstock, Swiss machining centers can produce increasingly complex and unique goods with much shorter cycle times than standard CNC lathes or CNC turning centers.
The experienced professionals at dti EXACT work with a wide variety of metals and plastics to create products for aerospace, automotive, manufacturing, medical, and more. We also provide live tooling for off-center or asymmetrical machining stages and employ bar feeding to continuously introduce material to the machining equipment for faster, seamless production.
Swiss Machining Processes
The multi-spindle Swiss machining equipment at dti EXACT can provide a variety of processes, such as:
Turning
In the turning process, a lathe spins the attached workpiece while a separate cutting tool removes excess material. The cutting tools incorporated into CNC Swiss machining equipment are extremely precise, ensuring close-tolerance widths and depths along two axes of motion. Turning processes can be conducted on the exterior or interior of a workpiece.
Profiling
Profiling changes the texture and dimensions of a planned surface, including vertical and slanted planes. The CNC machinery will detect undercuts, clean up rough edges, and otherwise remove excess material to correct imperfections.
Threading
To fasten parts into larger assemblies, manufacturers often need to create threaded holes in machined or manufactured components. Threaded fasteners are popular, easy to use, and cost-effective. Machining centers can create threaded holes with either a tap for cutting threads along the interior of a shaft or a die for cutting threads along the exterior of a shaft. For example, a nut would have its threads formed by a tap, whereas a bolt would have its threads formed by a die.
Drilling
Drilling processes use drill bits to create precision holes in workpieces. Along with precision drilling, we provide boring processes to refine and finalize the shape of drilled holes, so they exactly match the design specifications.
Facing
Turning may also include facing operations. During the first and last stages of machining a product, the cutting tool moves along the end of the workpiece to produce a datum. This datum is perpendicular to the part’s rotational axis and serves as a starting point to orient future machining and shaping stages.
Advantages of Swiss Machining
Swiss machining has become popular for creating small and highly precise parts. Some of the unique advantages of Swiss machining include:
- Design possibilities. Because of the versatility of Swiss machining and its ability to incorporate multiple different techniques, product designers can create more diverse and intricate parts.
- Specialization. Swiss machining supports industries that require extremely complex parts within strict tolerances, such as aerospace, medical devices, and more.
- High quality. Swiss machining centers provide simultaneous machining functions and minimize vibration during operations. This results in higher-quality parts.
- Automation. Swiss machining equipment can handle complex machining tasks without human intervention. Once the stock material has been fed into the machinery, CNC Swiss machines perform all operations to produce finished parts without the need for further operator action.
