Shenzhen EMAR Precision Technology Co., Ltd. is a professional manufacturer dedicated to high-precision CNC Machining. Its CNC precision machining workshop includes CNC lathes, CNC milling machines, vertical machining centers, CNC walking machines, CNC cutting machines and other CNC machine tools. It specializes in precision machining of various aluminum alloys, copper alloys, stainless steel, POM, profiles, plates and carbon steel. Its products cover medical equipment, optical components, robot parts, optoelectronic components, drone parts, automotive parts, communication and shaft accessories, etc. EMAR has years of product processing experience and combines actual CNC machining machines to analyze the differences between 4-axis CNC machining centers and conventional CNC machining.

Ordinary CNC machining only requires three axes, XYZ. A machining center that adds an additional rotating axis to the XYZ axes is called a four axis CNC machining, while a machining center that adds two rotating axes is called a five axis CNC machining center.

Four axis CNC machining has three different types of added rotation axes, identified as A, B, and C. The A axis is the axis that rotates around the X axis, and so on. The B axis corresponds to the Y axis, and the C axis corresponds to the Z axis. ABC, these three rotating axes are also known as dividing heads. Four axis CNC machining adds a dividing head to a three-axis machining center. The specific coordinate axis to be added depends on the customer's requirements

Similar to four axis CNC machining, a five axis machining center simply selects two of the three rotation axes A, B, and C, which can be AB, AC, or BC. It is precisely because five axis machining centers have one more rotating axis than four axis machining centers that the workpieces that can be machined by five axis CNC machining centers may not necessarily be machined by four axis machining centers, while the workpieces that can be machined by four axis CNC machining centers can be machined by five axis machining centers.

Four axis CNC machining can complete the linkage between a rotating axis and XYZ three linear axes to machine some complex surfaces, while a five axis machining center has an additional indexing head than a four axis machining center, so it can complete the linkage between two rotating axes and XYZ three linear axes to machine more complex spatial surfaces.
