Joint Stock Company Navoi Mining and Metallurgical Company (JSC NMMC) is one of the TOP-4 gold producer globally. The company is an industrial cluster, which has mastered the full production cycle from geological exploration of reserves in the subsoil, mining and processing of ore to obtaining finished products.

Milling cutters, such as solid milling cutters, inserted-blade cutters, and indexable-insert cutters, are also discussed. The article explains the capabilities and limitations of peripheral milling, face milling, and end milling methods. It concludes with a comparison of milling with broaching, planing or shaping, and grinding.
