Grinding and Surface Finishing consists of a finishing process that uses abrasive wheels to smooth flat surfaces to give the surfaces a more refined look by removal of imperfections on the surface of metal. Our specialized brands for Grinding and Surface Finishing machines include: NS Maquinas LMD 2500 / 3100/ 4100 .

Surface grinding produces a smooth finish on workpieces contain flat surfaces through a spinning wheel covered in rough particles. On the other hand, centerless grinding is a grinding process, and it uses two wheels (one regulating and the other is grinding) that remove the material from a workpiece until the desired diameter is achieved.

Surface finish refers to the process of altering a metal's surface that involves removing, adding, or reshaping. It is a measure of the complete texture of a product's surface that is defined by three characteristics of surface roughness, waviness, and lay. The surface roughness is the measure of the total spaced irregularities on the surface.

Surface Finish is a measure of the overall texture of a surface that is characterized by the lay, surface roughness, and waviness of the surface. Surface Finish when it is intended to include all three characteristics is often called Surface Texture to avoid confusion, since machinists often refer to Surface Roughness as Surface Finish.
