The shift from traditional manual lathes to CNC machines is not without reason. Lathes have traditionally been used for wood turning, metalworking, metal spinning, thermal spraying, part recovery, and glass processing. One or two centers typically hold the workpiece, with at least one center capable of horizontal movement to accommodate workpieces of different lengths. Due to their ease of setup, operation, repeatability, and accuracy, CNC lathes are rapidly replacing older production lathes. The work of CNC lathes is just one aspect of CNC machining.
But what is...CNC LatheFirstly, CNC stands for Computer Numerical Control, referring to machines operated by a computer system. CNC lathes operate according to precise design instructions to process parts into fine specifications. A CNC lathe is a type of machine tool where materials or parts are fixed and rotated by the spindle, as the cutting tools that work on the material are mounted on various axes and move along them.
A simple CNC lathe operates on two axes, with the cutting tool positioned in a fixed location on an 8 to 24-position turret. The rotating movement of the workpiece is called "turning." That's why certain types of CNC lathes are known as CNC turning machines. CNC lathes can produce finely rounded shapes with outer diameters (OD) and inner diameters (ID). According to the needs of different industries, these machines can process a variety of different structures. They are commonly used in the oil and automotive, aerospace, electronics, mining, power plants, steel and paper mills, and shipbuilding industries.
Modern CNC lathes are typically equipped with tools that can operate on multiple axes. Different types of machine tools can include X and Y axes, combining the di two turrets with other tools, or featuring di two spindles. This means that CNC lathes can perform additional milling, drilling, and tapping operations, thus forming a complete, even complex, part manufacturing process without the need to transfer parts to another machine for secondary operations.
