Precision Swiss Screw Turning

Swiss Lathes (also known as swiss machines, swiss-type turning machines, and sliding headstock machines) were originally designed for “long and skinny” parts (typically 6:1 length to diameter ratio or larger). The principle behind the swiss machine is that the bar moves to the tool rather than the tool moving to the bar (in the Z direction). This vastly reduces the amount of deflection during precision swiss machining since the cutting action occurs closer to the guide bushing. E.J. Basler has the capabilities to machine various material grades including red metals, 303, 304, and 316 stainless steel, and aluminum.

Generally, Swiss Machines have one or two spindles. This allows the Swiss Machining lathes to be fast and efficient in creating custom parts – some in as little as 10-15 seconds. This makes them great for large production runs on small-diameter parts.

As swiss-style lathes have improved in technology and speed, many non-typical Swiss-type parts can be run completely on these machines (in cases where it would take 4-5 operations in the past).

Typical tolerance ranges are in the +/-.0005” (+/-.013mm) range depending on the application.  With 11-Axis control, twin turrets, and 4-axis back working, Precision Swiss Turning can handle the most complex precision parts with speed and accuracy.
