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.
Figure 12.18 shows the schematic arrangement of a CNC grinding machine. X-axis is the in-feed direction of the grinding wheel. The longitudinal traverse of the grinding wheel is the Z-axis. The spindle rotation is the S1 axis. If the grinding wheel rpm is programmable, it provides the S2 axis. Swiveling of the wheel head is B-axis.
Cylindrical Grinding is a process where you use a grinding wheel rotating in a horizontal axis to cut or grind a cylindrical work-piece mounted on a chuck or between centers rotating in an axis parallel to the grinding wheel axis, in the same plane. Abrasive particles on the grinding wheel do the cutting of material.
Surface Grinding Work, Slideway Grinding Work, CNC Machining Services, Heavy Duty Machining Job Work, Services, Pune, Maharashtra, India.
