Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a CNC machining turning and grinding integrated machine. Background Technology

[0002] Numerical control machining (NC machining) refers to a process of machining parts on CNC machine tools. While the process specifications of NC machining are generally consistent with those of traditional machine tool machining, significant changes have occurred. NC machining uses digital information to control the displacement of parts and tools. It is an effective way to solve problems such as diverse part types, small batches, complex shapes, and high precision, and to achieve efficient and automated machining. NC machining refers to machining where the control system issues commands to make the tool perform various movements that meet the requirements, using numbers and letters to represent the technical requirements and machining process requirements such as the shape and size of the workpiece. It broadly refers to the process of machining parts on CNC machine tools.

[0003] Turning, also known as lathe machining, is a part of mechanical processing. Lathe machining mainly uses a cutting tool to turn a rotating workpiece. Grinding is a surface modification technique that generally refers to a processing method that uses a rough object (such as sandpaper containing high-hardness particles) to change the physical properties of a material surface through friction, with the main purpose of obtaining a specific surface roughness.

[0004] The typical machining process for cylindrical metal parts involves turning first, followed by grinding. Since turning and grinding are performed separately, the workpiece needs to be clamped multiple times, which is not only time-consuming and labor-intensive, reducing the machining speed, but also easily affecting the machining accuracy and reducing the quality of the workpiece.
