Title:
MACHINING METHOD AND MACHINING DEVICE HAVING HIGH EFFICIENCY AND LOW DAMAGE
Document Type and Number:
WIPO Patent Application WO/2021/232735
Kind Code:
A1
Abstract:
Disclosed are a machining method and machining device having high efficiency and low damage. The machining method having high efficiency and low damage comprises: providing a workpiece (300) and a machining unit (400); and the machining unit (400) machining the workpiece (300) at a preset machining speed that is not lower than a machining speed corresponding to when the material of the workpiece becomes brittle. The machining device having high efficiency and low damage is used for executing the machining method having high efficiency and low damage, and the device comprises: a base (100) for mounting the workpiece (300) and the machining unit (400); and a driving unit (200), which is connected to the machining unit (400) and is used for driving the machining unit (400) to reach the preset machining speed. In the machining method, by setting the machining speed of the machining unit (400) in a machining process, which results in the skin effect of sub-surface damage due to the material of the workpiece (300) becoming brittle, the depth of damage of the workpiece (300) is at a shallow surface layer, thereby reducing the depth of damage of the workpiece (300), ensuring the integrity of the workpiece, and improving the machining quality and machining efficiency.
