CNC TURNING AND MILLING ARE ESSENTIAL ELEMENTS IN MEDICAL MANUFACTURING For medical device components with simple machined features, CNC Turning and Milling satisfy the requirement. As a medical device contract manufacturer, Marshall provides a wide range of machining capabilities for their customers. FUNDAMENTAL MACHINING ELEMENTSMarshall Manufacturing typically devotes CNC turning or CNC milling to tool-making as well as secondary operations. Most any metal or rigid plastic material can be turned or milled in our equipment. Much of Marshall’s CNC Turning and CNC Milling capabilities are utilized for in-house tool making. Because tooling and fixtures are typically built as a single entity and not in multiples, the components within a custom tool are not made on production equipment. The CNC Turning Center (lathe) and CNC Mill are where our tool-makers build custom tooling, holding fixtures and even complete machines. These part specific tools designed by our engineers, are the foundation of Marshall’s drive to make quality parts in the most efficient manner possible. This mindset enables our customers to succeed. The CNC Turning ProcessThe process of CNC turning is carried out on a lathe. A stably mounted movable tool on an X – Y axis moves into the turning part. The tool then removes material from the outer diameter of the part. Straight, tapered, and contoured turns can be achieved on a turning lathe. The term “Turning” was given to the process because the part being generated is actually turning. In general, turning uses simple single-point cutting tools. The CNC Milling Process In the process of CNC Milling, the part is stationary and is fastened to a movable three-axis table (X – Y – Z). The movable table delivers the work-piece into a rotary drill, tap or cutting tool, in order to remove material from the work-piece. The types and characteristics of an end mill range from a straight flute to a tapered or contoured flute and from a square end to a ball end or bull-nose end. In addition, the CNC mill offers capabilities including, drilling, tapping and boring. Close tolerances are possible while achieving smooth finishes if desired.
