Machining device for producing ball studs on lathe has rotatable cutting tool rotating about rotary axis which intersects spindle axis and includes obtuse angle with same

摘要

The machining device has a cutting tool (2) rotatable about a rotary axis (5) and provided with at least one cutting element such as a hard metal plate spaced from the rotary axis. A straight line parallel to the main cutters (7,8) and intersecting the rotary axis includes with the latter an acute angle (12), preferably about 21 degrees. The rotary axis (5) intersects the spindle axis (6) and includes with same an obtuse angle (13) of about 109 degrees. The cutting tool is displaceable in the direction of the rotary axis and/or the workpiece (1) is displaceable in the direction of the spindle axis.
