Surface grinding is used to produce precise flat surfaces with tight tolerances and smooth finishes on metal or non-metal materials. It is commonly used in tool and die making, mould manufacturing, precision component finishing, and machine part refurbishment.

Modern surface grinding machines can achieve tolerances as tight as ±0.001 mm depending on the machine type, material, and operator expertise. High-precision CNC surface grinders can produce very flat surfaces with finishes ranging from Ra 0.2 to 0.8 µm.

Manual surface grinding machines require operator control for movements and grinding depth, making them suitable for simple tasks and small batches. CNC surface grinders are computer-controlled, offering higher precision, automation, repeatability, and efficiency for complex parts and high-volume production.

High-precision CNC surface grinders or automatic hydraulic surface grinders are ideal for die and mould work. These machines provide excellent rigidity, precise depth control, and fine surface finishes required for mould inserts, punches, dies, and hardened tool steel components.
