What is the Basic Principle of a CNC Lathe Machine?
CNC lathe is a machinery developed to perform cutting, boring, and turning operations on materials with high precision and speed. As opposed to conventional techniques, CNC lathes incorporate specific computational ascetics to regulate numerous factors of the matter. This cuts down on the involvement of human intervention, which may lead to the making of errors and hence enhances the accuracy of the machining done.
CNC lathe machines are basically used to hold the workpiece against a turning tool, which rotates the workpiece while cutting, drilling, and threading at the same time. CNC lathe machines are available in either vertical or horizontal configurations, depending on the requirements for the particular task at hand, and each has its unique strengths.
