What is Swiss CNC machining?

Swiss machining generally refers to the Swiss-designed CNC-operated lathe that turns parts in a radial motion as it cuts the workpiece. Swiss machining is a manufacturing technique that offers specialized tool cutting designed to turn metal stock into complex, slender, or delicate components that require tight tolerances. The process is not only cost-effective, but it presents increased precision over other similar methods.


Where is Swiss Machining Used?

Swiss CNC machining can produce small, intricate parts in high-volume for a number of industries, predominantly automotive, medical, defense, and electronics-related sectors. Parts produced by this type of machining are found in medical devices, optical equipment, firing pins, shafts, timepieces, connecting components for electronic devices and aerospace parts, and much more.

CNC Swiss turned components


CNC Swiss Machining Service is suit for machining high volume of small and complex cylindrical parts. The diameter of turned parts range from 1.1 mm - 38 mm (0.045"-1.5").  The straightness and concentricity tolerance is also very tight. At present, Kesu Group invested in 23 sets of 5-axis CNC Swiss Type Automatic Lathe. Such as Star SB 20R type G and Tsugami BO205-Ⅲ. At the same time, each machine is equipped with an IEMCA bar feeder. Which can fully realize the mass production of complex, slender, or delicate components that require tight tolerances.

At Kesu Hardware, Swiss machining can micro-machine tiny components with accuracy that are stronger, smaller, and lighter – faster. This all adds up to Swiss machines performing more complex machining operations than any other type of CNC machining system. High-volume production runs with this machining can cover numerous processes, including, milling, threading, drilling, boring, turning, and other custom requirements. One machine can perform several operations at once in a shorter period of time while offering designers more control in the production of complex parts. A variety of materials can be handled, such as stainless steel, aluminium, Inconel, titanium, nickel, and nickel-based alloys. 

All in all, Kesu Hardware's precision CNC Swiss machining is competitive on  complex, slender, or delicate components that require tight tolerances, as well as some of the simpler turned products.

How the precision CNC swiss machining machine works

The Swiss machine works by feeding the bar stock through a guide bushing that firmly supports the material as it is fed into the tool area of the machine. In addition, only the part of the bar being machined enters the machining area, which means that the material is held tightly in place for increased stability and accuracy.

With conventional CNC lathes, the workpiece is usually rotated quickly in a fixed position and held firmly at one or both ends. In contrast, with a Swiss lathe, the workpiece can both rotate and move back and forth along the Z-axis while various tools cut features of the part. In addition, Swiss lathes can perform multiple operations in multiple areas at the same time, whereas conventional lathes can typically perform only one operation at a time.

While Swiss machines are traditionally used to machine turned parts such as screws, Swiss machines can also produce complex parts with no turned surfaces at all.

Advantages of CNC Swiss machining

Swiss-style lathes have the advantage of being both accurate and fast. They can hold tolerances as small as tens of thousands of inches, making them ideal for applications that always require the same measurements. They can also produce simple parts with short cycle times, as little as 10 seconds depending on the part. Much like 5-axis machining, Swiss machining lathes can rotate parts along 5 different axes to make the most precise cuts on each part.

Our advanced machinery can produce complex and intricate shapes as well as standard shapes.

Why is Swiss Machining?

Swiss machining  is a precision turning processing  that can complete lathe, milling, drilling, boring, tapping, engraving and other compound processing at the same time. Swiss CNC machining is mainly used for batch processing of precision hardware and shaft special-shaped non-standard parts.

Our CNC Swiss turned parts clearly demonstrate our ability to machine complex micro components in a size range nearly invisible to the naked eye. Like our name says, we specialize in machining miniature, precision micro components from both free machining and non-free machining materials. Our  Swiss CNC turning machines allow us to provide high quality precision turned parts. The more complex and critically toleranced the micro component is, the more cost effective solutions we can provide you.
