CNC Swiss Lathe Machining: Uses and Applications

Swiss style turning machines are similar to CNC lathes or turning centers, but are faster and more accurate than traditional CNC turning centers. This is because Swiss Precision Machining allows milling, drilling, turning and tapping to be accomplished on each Swiss turning machine. Swiss Turning or Swiss Screw Machining refers to high volume production of miniature high precision cylindrical parts. These Swiss machined parts are often call micro pins or micro shafts.Get more news about Precision Swiss Lathe,you can vist our website!

Unlike many other types of screw machines, Swiss machines generate the features of the part by moving the material and the tool at the same time. Newer Swiss-type screw machines are CNC (Computer Numerical Controlled). Older machines were cam operated, so each different part required a new set of cams. A Swiss-type screw machine is an automatic lathe that has a sliding headstock and a guide bushing. The sliding headstock is the part of the machine that holds the bar stock (usually 12-foot metal or plastic bars) and rotates it (usually 1000-10,000 RPM depending upon the diameter and type of material). The headstock contains the collet, which clamps the material. The material is then fed through a guide bushing, which is usually made of carbide. The bushing is adjusted so that the material can slide through it, but tight enough to keep the material from flexing away from the cutting tool. The guide bushing allows Swiss-type screw machines to hold very tight tolerances. The cutting tools (brazed carbide turning or cut-off tools or insert tools) move in and out of the material to create required diameters while the headstock moves the material forward to create required lengths.
For precision machining applications, manufacturers use a range of CNC machines to make simple and complex parts. Typical machines that customers hear about include milling machines, grinding machines, and lathes. Many CNC machine tools operate by having a stationary workpiece as the cutting tools rotate around it to remove the materials until the finished part is made. For the case of a CNC lathe, the mounted part rotates as the cutting tools work along the length of the workpiece.

A machine getting more attention across several industries is the Swiss lathe machine. Companies in medical and electronics have used this machine to produce parts quickly. Yet now more industries are recognizing the benefits of a CNC Swiss lathe machine for their parts production.
What is a Swiss Lathe?
A Swiss lathe has an extra function to a traditional lathe. It rotates the mounted workpiece and also slides the workpiece laterally along the Z-axis through the guide bushing. Instead of the whole entire workpiece being exposed to the cutting tools, only a piece of the workpiece is tooled as it advances through the guide bushing.

The main advantage of this setup is that the cutting tools could work on the part close to where the workpiece is supported by the bushing. The Swiss lathe offers less deflection to long and narrow parts due to this added support right where the tool operates, increasing accuracy and repeatability. Manufactured parts from a Swiss lathe can have a length-to-width ratio of 20:1 and small diameters of under 0.125″.

Applications and Uses for Swiss Lathes
CNC Swiss lathes perform milling, drilling, knurling, turning, and boring processes. Numerous tools and several axes (up to 13-axes) may be used to complete the part. In addition, operators may feed numerous workpieces through the feed along the automatic bar loaders during production runs.

These machines were first used in the making of watch parts. Now, companies in defense, medical, aerospace, electronics and many others find amazing benefits with this machine. Types of parts produced by a Swiss lathe include:
