Profile: Ripley Machine & Tool Co. specializes in providing machining and grinding solutions. We machine parts for various industries including pumps and valves, trucking, fluid control, oil and gas, electronics, medical and more. Typical parts that we machine include valves, motor mounts, enclosures, and custom equipment replacement parts. CNC milling is a machining process that is used to manufacture various parts through subtraction machining. The process shapes various materials, such as metals or plastics, by keeping them stationary and rotating cutting tools around them. The material is mounted to a table, while the cutting tools are mounted on a rotating spindle that can rotate on many axes to allow for more freedom of movement, and thus more capabilities for creating complex shapes.
