CNC Turning Services
What is CNC Turning?
CNC turning creates parts by rotating a blank on a chuck while stationary cutting tools remove material. It's ideal for producing symmetrical parts along a central axis and is often faster and more cost-effective than CNC milling.
CNC Turning Machine Parts
Familiarizing yourself with the key components of a CNC turning machine is essential to understanding the turning process. While the specific parts may vary by manufacturer, type, and machine capacity, most CNC turning machines share several fundamental components:
Control Unit: The brain of the machine, it processes operator input and translates it into precise movements and operations.
Spindle: This part holds and rotates the workpiece, ensuring it stays in position during the turning process.
Turret: A rotating platform that houses and indexes multiple cutting tools, allowing for versatile operations.
Tool Holder: An adjustable device mounted on the turret that securely holds the cutting tools in place.
Cutting Tool: The actual tool responsible for removing material from the workpiece to achieve the desired shape and finish.
