CNC machining refers to the machining process proceed by Computerized Numberical Control (CNC for short). It is aided by the CNC to reach a high and steady accuracy with less labor cost. Machining is any of various processes in which a piece of raw material is cut into a desired final shape and size by a controlled material-removal process. The processes that have this common theme, controlled material removal, are today collectively known as subtractive manufacturing, in distinction from processes of controlled material addition, which are known as additive manufacturing.

Exactly what the “controlled” part of the definition implies can vary, but it almost always implies the use of machine tools (in addition to just power tools and hand tools). This is a process used to manufacture many metal machined products, but it can also be used on materials such as wood, plastic, ceramic, and composites. The CNC machining covers many different processes such as milling, turning, lathing, drilling, honing, grinding…etc.

The machining center is developed from the CNC milling machine. The biggest difference from the CNC milling machine is that the machining center has the ability to automatically exchange machining tools. By installing tools for different purposes on the tool magazine, the machining tools on the spindle can be changed by the automatic tool changer in one clamping to realize multiple machining features.

The CNC machining center is a high-efficiency automated machine tool that is composed of mechanical equipment and a CNC system and is suitable for processing complex parts. The CNC machining center is currently one of the most widely used CNC machine tools in the world with strong comprehensive processing ability. It can complete more processing content after the workpiece is clamped at one time. The processing accuracy is high. For batch workpieces with medium processing difficulty, its efficiency is 5-10 times that of ordinary equipment, especially it can complete Many processings that cannot be completed by ordinary equipment are more suitable for single-piece processing with more complex shapes and high precision requirements or for small and medium batch production of multiple varieties. It concentrates the functions of milling, boring, drilling, tapping and cutting threads on one device, so that it has a variety of technological means.

Machining centers are classified into horizontal and vertical machining centers according to their spatial position during spindle machining. Classified according to process use: boring and milling machining center, compound machining center. According to the special classification of functions, there are: single workbench, double workbench and multi-workbench machining center. Machining centers with single-axis, dual-axis, three-axis, four-axis, five-axis and interchangeable headstocks, etc.

CNC machining is the kind of precision machining by CNC machines such as advanced machining centers which have top end 5 axis machining center, 4 axis double platform machining center, or CNC turning lathes which can also be developed to CNC turning center having capability of changing more than 15 cutters within one holding shift; CNC milling machine and CNC drilling and tapping centers. Precision machining of steel casting is different from machining of steel profile. Precision casting has already achieve quite exact shape of what is desired, thus it saves lots of machining compared with machining from steel profile directly. Also because of this reason, we usually have to consider machining surface and proper machining allowance before casting. Our regular procure is to work out raw casting drawing along with machining drawing to specify machining area and machining allowance on the drawing.

RMC investment casting foundry has equipped with 4 axis machining centers, 15 sets of CNC turning lathes and 3 sets of cnc milling machines, along with assistant common versatile turning, milling, tapping, drilling and grinding machines, we have the capability of machining nearly all kinds of steel castings.

Also called precision machining, the CNC machining could reach a very high accuracy in geometical tolerance and dimensional tolerance. With our CNC machines and Horizontal Machining Centers (HMC) and Vertical Machining Centers (VMC), we can almost meet all of your required tolerance grades.
