Learn Everything You Need to Know About NC Machining: Processes, Materials, Applications, and Costs
Introduction
NC machining is a technology used in the fabrication of parts and components for a wide variety of applications. It involves the use of computer numerical controlled (CNC) machine tools to produce parts from a range of materials. The process offers both precision and accuracy, making it ideal for parts with complex geometries. In this article, we will explore the processes, materials, applications, and costs associated with NC machining.
What is NC Machining?
NC machining is a manufacturing process that uses computer numerical control (CNC) machines to create parts and components from a range of materials. CNC machines are automated machines that are programmed by a computer to cut and shape materials according to a set of coordinates and instructions. This process is also known as numerical control (NC) machining or CNC machining.
NC machining is a versatile process that is used to create parts with precise dimensions and complex geometries. It is commonly used in many industries, including the automotive, aerospace, medical, and food production industries. NC machining is also used to create prototypes and one-off parts for testing and development.
Processes used in NC Machining
NC machining involves several different processes, including milling, drilling, turning, and grinding. Each of these processes has its own unique characteristics and advantages. Let’s take a closer look at each of these processes.
Milling
Milling is a process that involves cutting away material from a workpiece with a rotating tool. The tool is guided along a predetermined path that is specified by the design of the part or component. Milling can be used to create flat surfaces, slots, holes, pockets, and other features. It is often used to create parts with complex 3D geometries.
Drilling
Drilling is a process that involves creating holes in a workpiece using a rotating drill bit. It is used to create cylindrical holes of various sizes and depths. It is commonly used in the production of parts with threaded holes, such as bolts and screws.
Turning
Turning is a process that involves rotating a workpiece against a cutting tool in order to shape and finish the material. It is used to create parts with cylindrical shapes and geometries, such as shafts and spindles.
Grinding
Grinding is a process that involves the use of an abrasive wheel to remove material from a workpiece. It is used to create flat surfaces, contours, and other features. It is a finishing process that is used to improve the surface finish of the part or component.
Materials Used in NC Machining
NC machining can be used to fabricate parts and components from a variety of materials, including metals, plastics, ceramics, and composites. Each of these materials has its own unique properties and advantages.
Metals
