The CNC four axis CNC machining center has started to adopt the machining treatment of the curved surface, that is, the machining treatment of the impeller. In the past, CNC four axis CNC machining centers were widely used for processing polyhedral components, vortex lines with multiple rotation angles (circular oil grooves), spiral grooves, circular camshafts, and cycloidal gears.
From the processing of goods, we can conclude that CNC four axis processing has the following significant characteristics: based on direct participation with axis rotation, the processing of perfect flawless curved surfaces becomes possible, and improves the processing accuracy, quality, and efficiency of free area curved surfaces; The processing of workpieces that cannot be processed by three-axis processing equipment or require clamping for longer lengths (such as long wheelbase tangential processing).
It can be completed through a four axis rotating worktable, reducing clamping time, processing flow, and achieving maximum limit through single position positioning to end multiple process processing and reduce position positioning errors; The milling cutter has been greatly improved, extending its lifespan and benefiting production concentration.
There are generally two processing methods for CNC four axis CNC machining centers: positional positioning processing and interpolation processing, each matching polyhedral machining parts and rotating bodies can be classified for processing. Nowadays, taking a four axis CNC machining center with A-axis rotation as an example, the two processing methods are explained separately.
