Swiss CNC Machining

 Swiss Machining Definition

Swiss CNC machining is a specialized process designed for the manufacturing of small-sized, high-precision turned parts. Originally developed for the Swiss watchmaking industry, Swiss CNC machines, also known as Swiss automatic lathes, Swiss screw machines, or Swiss-type lathes, have evolved over the years and found widespread applications in various industries for large-scale, high-precision manufacturing— and with good reason.

 

A Swiss CNC machine is designed to cut bar stock fed through a guide bushing while keeping the tool stationary. The collet recesses behind the guide bushing provide better support for the clamped bar stock, preventing direct exposure to the bed and fixtures. This enables the machine to process materials quickly and tightly. Furthermore, the cutting tool, working closer to the guide bushing, plays a crucial role in reducing tool deflection, vibration, and improving part accuracy.

 

How Do Swiss-Type Lathes Work?

A Swiss lathe is a specially designed machine tool that works differently than a traditional lathe. Here's how a Swiss lathe works:

 

Unique Sliding Spindle Box Design

 

Swiss lathes take a unique approach by using a sliding spindle box that cleverly guides the workpiece to enter axially under the action of the cutting tool.

 

The Unique Synergy of Guide Sleeves and Guide Rods

 

With the unique combination of guide sleeves and guide rods, the spindle box precisely guides the feed of the workpiece, creating a unique material machining experience.

 

Innovative Cutting Tool Holding

 

The innovative cutting tool holding method is unusual and allows the workpiece to be cut and machined in a unique cutting tool.

 

Z-Axis Motion and Unique Continuous Feed

 

The Swiss lathe spindle box uniquely swings on the Z-axis, leading to the continuous feed of the workpiece. Through the unique synergy of the guide sleeve and guide rod, it creates a unique and efficient continuous machining process.

Benefits of Swiss CNC Machining

Swiss CNC machining’s superior performance stems from its precise geometry and the mechanical design of its guide sleeve and tool area. Tools operate efficiently near the guide bushing, slashing tool transition time to one second or less.

 

The tool area can hold over 20 tools, greatly reducing setup time. It can remove material in one heavy cut, eliminating deflection and achieving an excellent surface finish without additional sanding.

 

This technology allows for the completion of complex parts in a single cycle, enhancing accuracy. It supports multiple operations in one cycle, enabling quick shipment post-production. The automatic bar feeder facilitates continuous, unattended operations, boosting efficiency even in unmanned settings. The sliding headstock and guide bushing design meet tight tolerance requirements.

 

Comparing Swiss Machining Vs CNC Machining

Faster Cycle Times

Modern Swiss lathes have 7 to 13 axes and are able to perform multiple operations faster in a single machining cycle, such as drilling, grooving, Swiss milling, thread cutting and parting, etc.

 

In contrast, traditional CNC lathes usually only have 3 to 5 axes and may not be able to complete the machining of parts in a single cycle, limiting production efficiency.

Coolant Type

Swiss lathes frequently utilize oil as a coolant, significantly enhancing the precision of tolerances achieved during machining. Oil possesses a lower heat capacity when compared to water-based coolants, enabling Swiss machining processes to conduct and dissipate heat more efficiently.

Segmented Machining

Unlike CNC machining, which often fabricates a part in a single operation, Swiss machining strategically produces parts in distinct sections. This methodical approach ensures that the final dimensions of each section meticulously meet the required tolerances, enhancing overall precision and quality.

Bushing

Typically, machining involves clamping rod-shaped material in a chuck behind a guide bushing. In Swiss machining, the cutting tool runs close to the guide bushing to prevent deflection. Therefore, Swiss machinery has a movable headstock that remains within the required tolerances regardless of the length of the workpiece.
