What Is CNC Machining? An Overview of the CNC Machining Process

Computer Numerical Control (CNC) machining is a manufacturing process in which pre-programmed computer software dictates the movement of factory tools and machinery. The process can be used to control a range of complex machinery, from grinders and lathes to mills and CNC routers. With CNC machining, three-dimensional cutting tasks can be accomplished in a single set of prompts.

Why are CNC machined aluminum parts popular in manufacturing?

Aluminum is a choice of material for many manufacturers across the globe. Because of its excellent machinability and other characteristics, it is the preferred option for different applications. Aluminum also offers interesting mechanical and thermal properties. Besides, Aluminum is relatively easy to shape and can be drilled and milled effortlessly. Aluminum alloy is used more as compared to other low-weight metal materials. Aluminum is also an ideal material for prototypes.

Benefits for CNC machined aluminum parts

As we mentioned before, brass provides advantageous properties that make it an ideal option for a variety of applications. Why is that? When it comes to CNC machining, there are a few fundamental properties that make brass and copper parts ;outstanding.

Stainless steel part ;has the characteristics of corrosion resistance, scale resistance, acid resistance, impact resistance, and toughness in a wide temperature range. Depending on the environment, it can provide a variety of grades and surface finishes, making these parts an ideal choice for many applications. The chromium in the steel allows the formation of a rough, invisible, corrosion-resistant chromium oxide film on the steel surface. If the material is mechanically or chemically damaged, the film will repair itself (assuming oxygen is present). In addition, it is 100% recyclable feature provides a new way for stainless steel as an environmentally friendly material. Therefore, it has been widely used in heavy industry, light industry, daily necessities industry, and building decoration industries.

Plastic parts ;are a ubiquitous part of daily life. From food packaging and gardening tools to laptops and sports equipment, it's hard to go a day without interacting with manufactured plastic 

Most subtractive CNC machines such as mills, water jets, and plasma cutters have the workpiece secured to a bed and the cutting done by a spinning tool. To cut, the tool moves across the workpiece or a tool head shoots at it. In contrast, CNC turning ;reverses that process by rotating the workpiece and cutting away at it (by moving a static cutting bit against the workpiece).
