What is CNC Machining?
CNC (Computer Numerical Control) machining is a versatile manufacturing process that uses automated cutting to shape materials like metal, plastic, or composites. CNC machines, including 3-axis, 4-axis, and 5-axis mills, lathes, and planers, provide flexibility for precision and complex geometries. Depending on the operation, either the workpiece or the tool moves, or both for greater accuracy.
At Keywin, our advanced equipment and skilled team deliver high-precision, efficient custom machining solutions to meet your manufacturing needs.
