Brass cnc lathe parts used in computer numerical control (CNC) lathes, which are machines that use computer programs to control the movements of cutting tools that shape and finish workpieces made of materials such as metal, plastic, or wood. These parts can include things like chuck jaws, tool holders, and feed screws, which are used to hold, clamp, and move the workpiece and cutting tools during the machining process. Brass is a common material for CNC lathe parts because it is strong, durable, and resistant to corrosion, making it well-suited for use in manufacturing environments.
