Chemical Machining

Chemical machining is the material removal process for the production of desired shapes and dimensions. It is done by selective or overall removal of material by a controlled chemical attack with acids or alkalies

Chemical Machining Working Principle.

The chemical machining working principle is chemical etching. The part of the workpiece whose material is to be removed is exposed to a chemical known as enchant. The enchantment removes the metal from the chemical attack. The method of making contact of material by the enchant is masking.

Chemical Machining Process.

The process can be applied to different types of operations such as milling, blanking, and engraving. The different chemical machining processes can be classified as:

1) Chemical milling

2) Chemical blanking

3) Chemical engraving

Chemical machining for some special purposes can also be achieved by using a jet of reactive gas, e.g., chlorine on the machining zone. This is known as Gaseous Chemical Machining or Hot Chlorine Machining and can be used for deburring of metal parts.
