What Is Photochemical Machining?
Chemical processing refers to the method used in the materials industry to etch workpieces such as metals and glass with chemical reagents, or to perform etching and grinding to obtain a certain shape, size, and surface finish. For example, etch the scribe line with strong acid, grind the surface of the workpiece with chrome oxide chemical ointment, etc. [1]
Chemical processing
- It can process any metal material that can be cut without being restricted by the properties such as hardness and strength.
- Suitable for large area processing, and can process multiple pieces at the same time.
- Does not produce stress, cracks, burrs, and surface roughness reaches Ra1.25 ~ 2.5m.
- Easy to operate.
- Not suitable for processing narrow slots and holes.
- Should not eliminate surface unevenness, scratches and other defects.

- Chemical processing was applied earlier. At the end of the 14th century, chemical etching methods have been used to etch the patterns and marks on the surface of samurai's armor and knives and swords. In the 1820s, Niepce in France invented the solar lithography method using the photosensitivity of refined asphalt. Appeared again soon
