What is Swiss CNC Machining?

The key to CNC Swiss turning is adding a bar feeder that spins the round bar and slides and feeds through the guide bushing in the Z-axis direction.

CNC Swiss lathes provide stationary support for the workpiece while the part is machined. This design enables the machine to hold tight tolerances and produce parts back to back. 5 axis Swiss-type machines have milling and drilling capabilities.

WHEN to Use a Swiss Type Lathe

It is best when parts have milled and turned features that require precision machining. Swiss CNC machining allows for many milled features (flats, hex edges, slots, left hand threading etc.) to be produced during the turning process without the need for multiple setups on additional equipment, providing greater production efficiencies with one process.

The rotary broaching process can be performed on these machines to cut standard or custom shapes into or onto a workpiece.

The ID centered rigid tapping or thread milling processes can be performed on the APSX-NANO Desktop CNC Swiss. You can also thread milling by using the live tools. There are multiple Swiss tooling companies that you can find a perfect tool for each application.

When smaller, more complex parts are needed. Typically, those parts are non-standard parts and can not be sourced directly. Examples would be tamper proof bolts, special nuts, pins, custom mechanical parts, nozzle inserts, pick and place tips, antique jewelry and watch parts, gunsmith parts, custom knives, custom musical instrument bolts and screws, fasteners, rc car and drone parts. Especially the screws (standard or custom) made out of Titanium (Grade 5) are expensive to buy. 

Most of the Swiss-type parts are less than 1” (25mm) in diameter, with the majority being less than ¾” (16 mm) in diameter.
