Basics of the CNC Lathe

Provided by: ToolingU

“Basics of the CNC Lathe” explains the components and functions of both the chucker and bar machine CNC lathe varieties. CNC lathes have spindles that spin workpieces held in chucks or collets. A carriage and cross slide move along ways to position cutting tools against the spinning part. A cutting tool may remove metal from the inside or outside surface. Carbide inserts are the most common cutting tools used in turning operations. Turning centers are also capable of creating holes with the use of drills and reamers. The turret rotates to place the required tool in the cutting position. It is essential for a CNC lathe operator to be familiar with machine basics prior to executing any cutting operation. A trained operator can use a CNC lathe to create precise parts safely and consistently. After taking this class, users should be able to describe the basic functions and general machine components of a CNC lathe.
