Precision parts machining offers numerous advantages, which we've previously discussed. The most obvious advantage is achieving a level of precision unattainable by conventional machining. This high precision relies on sophisticated machining equipment and accurate control systems, utilizing precision masks as intermediaries to achieve extremely fine control over the amount of material removed or added to the surface layer. So, what are the characteristics of precision parts machining? Let's take a closer look:
I. Precision Parts Cutting Machining
This mainly includes precision turning, mirror grinding, and lapping. On a precision lathe, micro-turning is performed using finely ground single-crystal diamond tools, cutting to a thickness of only about 1 micrometer. This is commonly used for machining high-precision, highly smooth parts such as spherical, aspherical, and planar mirrors made of non-ferrous metals.
II. Precision Parts Machining
When the precision of precision parts machining is targeted at nanometers, or even atomic units (atomic lattice spacing of 0.1–0.2 nanometers), ultra-precision cutting methods are no longer sufficient. It becomes necessary to utilize specialized precision parts machining methods, applying chemical, electrochemical, thermal, or electrical energy to exceed the interatomic bonding energy, thereby removing some of the interatomic adhesion, bonding, or lattice deformation on the workpiece surface to achieve ultra-precision machining. These methods include mechanical-chemical polishing, ion sputtering and ion implantation, electron beam lithography, laser beam machining, metal evaporation, and molecular beam epitaxy.
