Technical details and manufacturing context for Surface Grinding Machine

Definition
A surface grinding machine is a precision machine tool designed to produce extremely flat and smooth surfaces on metallic and non-metallic workpieces. It operates by rotating an abrasive grinding wheel against a stationary or reciprocating workpiece, removing minute amounts of material to achieve tight dimensional tolerances and fine surface finishes. These machines are essential in manufacturing for creating precise reference surfaces, achieving specific surface roughness values, and finishing components to exact specifications. The machine typically consists of a reciprocating worktable, a vertical spindle carrying the grinding wheel, and a coolant system. Workpieces are often held by a magnetic chuck or fixture. The table moves back and forth under the wheel, while the wheel is fed vertically to control depth of cut. Cross-feed movement allows grinding across the entire width. Coolant is applied to dissipate heat and flush away swarf. Typical specifications include a maximum grinding length of 500–1000 mm, width of 200–500 mm, and distance under wheel of 300–600 mm. The grinding wheel diameter ranges from 200–400 mm, with spindle speeds of 1500–3000 rpm. Table travel speed is 5–25 m/min, and motor power is 2.2–7.5 kW. Achievable surface finish is Ra 0.1–0.4 per ISO 1302. The machine operates on a 380 V AC, three-phase, 50/60 Hz supply (IEC 60038) and within an ambient temperature of 5–40 °C. Overall dimensions range from 2000×1500×1800 to 3000×2000×2500 mm, with a net weight of 2000–5000 kg. These values are reference ranges; verify model-specific data with the manufacturer. The machine is used in tool rooms, job shops, and production lines for finishing components such as dies, molds, and machine parts. Proper maintenance includes regular inspection of the wheel, spindle, and coolant system. Failure to maintain can lead to vibration, poor surface finish, or wheel breakage. Always follow safety guidelines and use appropriate guards and personal protective equipment.
Working Principle
The surface grinding machine operates by mounting a workpiece on a magnetic chuck or fixture on a reciprocating table. A high-speed rotating abrasive grinding wheel, mounted on a vertical spindle, is lowered to make contact with the workpiece surface. As the table moves back and forth horizontally beneath the wheel, the abrasive grains on the wheel's periphery remove material through a combination of cutting and shearing actions. The vertical feed mechanism allows precise control over the depth of cut, while cross-feed movement enables grinding across the entire workpiece width. Coolant is typically applied to dissipate heat, flush away swarf, and improve surface finish.
