CNC Lathe Machine

A CNC Lathe Machine is a turning center where a workpiece is rotated on a spindle while cutting tools remove material. It is computer-controlled and used for cylindrical parts.

Type of CNC Lathe Machine

Ranges from 2-axis lathes (with X and Z axes) to multi-axis turning centers (with C-axis live tooling and sub-spindles) enabling milling/drilling operations. Some lathes are Swiss-type (sliding headstock) for very small parts.

Application in Various Industries

Used to machine shaft-like parts: shafts, bushings, threads, pulleys. Industries include automotive (axles, pistons), aerospace (turbo shafts), oil/gas (valves), and general manufacturing. CNC lathes are valued for high precision on round profiles.

Materials: Similar to VMCs, the machine’s bed and base are often cast iron. The spindle uses hardened steel. Cutting tools (turning inserts) are carbide or ceramics. Workpiece materials can be any machinable metal or plastic.

Material Selection Considerations

  • Machine construction emphasizes rigidity. For example, heavy-duty lathes use welded steel frames with cast iron cross-sections to minimize vibration. The chuck and tool turret components are made from hardened alloy steel for durability under load.
