Using General lathe to processing angle round this class has angle of mechanical parts common has two species method: a is Dang turning more short of cone angle Shi, General is with turned small skateboard method, turning Shi put small skateboard turned a cone half angle a/2, makes car knife of movement track and by to turning of cone pigment line parallel can, while to note turned small skateboard Shi must to attention turned direction right. Another is forming cutter method.
Shortcomings of this two methods is: due to travel restrictions by small Skate but length shorter tapered; turning only when manual feed, labor intensive surface roughness of difficult to control using molding lathes to has good rigidity, or prone to vibration, and applies only to turn short outer cone; production efficiency is low. Master cut because of their low efficiency were reluctant to process these parts, especially flute parts less processing.
With the rapid development of science and technology, CNC lathe with high efficiency, high accuracy, and high flexibility characteristics, has been widely used in mechanical manufacturing, has become one of the most widely used CNC machine tools. These parts in NC lathe programming process will be able to achieve a multiplier effect.
