Advantages of a B-Axis Swiss-Type
Learn how a Northeastern shop leverages a Swiss-type lathe with a B-axis milling spindle to produce small batches of complex parts.
The signature element of this Swiss-type machine is its B-axis milling spindle. This differs from conventional Swiss-type designs that use gang-style tools that are fixed in their orientation with the part, either perpendicular to the face or diameter of the barstock.
When equipped with a B-axis milling spindle, a Swiss-type lathe essentially becomes a five-axis turn-mill with the bonus of a sliding headstock. The sliding-headstock is what enables the machine to effectively turn long parts with small-diameters, while the B-axis milling spindle can approach workpieces in the machine’s main or subspindle at a variety of angles.
