The Basics Of CNC Turning
Turning is used for any rotationally symmetrical shape, to remove material quickly while leaving an excellent surface finish that sometimes requires no post-processing.
We use CNC turning not only to manufacture parts and prototypes but also to make mold tools, which can be used for our plastic injection molding or presure die casting services.
How CNC Turning Works
Turning involves holding the workpiece in a horizontally-mounted, adjustable spindle. As the workpiece rotates, various cutting tools are applied to the piece to create circular shapes and features like rings, grooves, slots, contours, radii, internal bores and threads. On our Haas turning mills, an extra axis of movement allows us to work perpendicular to the lathe spindle for making square faces or boring holes. This opens up many new machining possibilities.
When all turning operations are completed, the part is cut from the stock for further post-processing. The CNC lathe is then ready to repeat the operation with little-to-no set-up time in between.
Types Of CNC Turning
The most common are 2-axis CNC lathes and Swiss-type lathes. Swiss-type lathes are unique in that stock material is fed through a guide bushing, allowing the tool to cut nearer to the point of support, which makes them particularly useful for long, slender turned parts and micromachining. Some Swiss-type lathes also come equipped with a second tool head that operates as a CNC mill, allowing them to perform multiple machining operations without having to move the workpiece to a different machine. This makes Swiss-type lathes extremely cost-effective for complex turned parts.
