The invention provides a machining apparatus having a retaining component. The above retaining component has a light retaining workbench that is easy to dismount. The provided machining apparatus comprises the retaining component for holding a to-be-machined object; a machining component for machining the to-be-machined object held on the retaining component; and a machining feeding component for relatively machining and feeding the retaining component and the machining component in the machining and feeding direction. The retaining component is composed of a retaining workbench and a supporting pedestal. The retaining workbench has an attraction region for attracting and holding the to-be-machined object, and a periphery region surrounding the attraction region. The supporting pedestal supports the retaining workbench and enables the retaining workbench to be detachable, and attraction is transmitted to the above attraction region. The retaining workbench is formed by multi-porous ceramics, and a coating layer is applied to the region, except the attraction region, of the retaining workbench. |
