With a 12 station turret, gang type tool post, and sub-spindle,
NST Series multi-axis lathes provide complete machining solutions for larger diameter precision parts.
CNC Swiss machines
accommodate maximum bar diameters of 45mm, 56 mm and 67 mm and maximum turning length of 150 mm.
Main spindles with 15 HP (11.2 kW) – 20 HP (15 kW) and 5,000 – 6,000 RPM speed capacity, and 7.5 HP (5.6 kW), 5,000 – 6,000 RPM sub-spindles are accompanied by live tools with 1.3 HP (1 kW) and 6,000 RPM maximum speed. C-axis contouring is available on both main and sub-spindles.
The machines can apply a maximum of 39 tools to completely machine parts while performing a wide variety of simultaneous operations.
Excellent rigidity results from the use of FEA technology in machine structure design.

Is it worth the money to buy a Swiss lathe?
Does your shop run large quantity batches of parts? Do you need the ability to run lights out? Are you running family groups of similar style parts? If the answer to any of these questions is yes, then a Swiss lathe is a likely a great option for your needs. With minimal changeover and the ability to machine parts with a high degree of accuracy, Swiss lathes can decrease your downtime and reduce costs related to returned parts.
Is a fixed or rotary guide bushing preferred?
In most cases, a rotary guide bushing is preferred. The rotary guide bushing acts as a slave to the material, spinning along with the main spindle. If the rotary guide bushing is properly set, material is prevented from slipping in the guide bushing. This results in an excellent surfact finish because the guide bushing stays in contact with the part, minimizing marring and scratching. On the other hand, a fixed guide bushing stays static as the bar in it spins. Because of this, it a tendency to damage the material it is holding. If you're making a part that you are turning the OD, for example, you don’t want marks left on the outside of your material from the fixed guide bushing.
How does a Swiss machine work?
The main spindle unchucks the workpiece, giving you the correct amount of stroke based on the length of the part. The guide bushing will continually feed material into the tooling to create the desired features. The close geometry construction of the machine allows the tool to work within millimeters of the workpiece, which reduces chip-to-chip time to a second or less. With the use of a guide bushing, a tool can also take a heavier depth of cut without jeopardizing tolerances. Swiss lathes are ideal for length to diameter ratio parts. If you’re running a 6” long, 0.20” thick part on a conventional lathe, you’d have warping. Held in a guide bushing, that same part can be machined in one cut. Once the machine does a pick off process with the sub-spindle side, any secondary operations on the back of the part can be achieved here at the sub. The part is then dropped into a conveyor that ejects it out the front of the sub. You can also utilize a long-shaft discharge unit, so the next piece of bar to be machined pushes the part out the back of the sub.
