The 7140 surface grinder is a high-precision metal processing equipment, widely applied in machinery manufacturing, mold processing, precision instrument production, automobile parts manufacturing, aerospace components processing, and tool sharpening industries. It is mainly used for grinding flat surfaces of workpieces, and can also process inclined surfaces, stepped surfaces, and special-shaped surfaces with auxiliary fixtures.

This machine is suitable for grinding ferrous metals, non-ferrous metals, hard alloys, ceramics, and other materials with high hardness and precision requirements. It is an essential equipment for precision processing in small and medium-sized enterprises, mold factories, precision processing workshops, and research institutions, ensuring the flatness, parallelism, and surface finish of workpieces meet strict technical standards.

• Superior Processing Precision & Surface Quality: Equipped with high-precision quenched and ground guideways and a precision spindle system, the machine minimizes vibration during operation and ensures excellent motion accuracy. The grinding wheel spindle adopts high-quality bearings and precise dynamic balance treatment, enabling it to achieve a surface roughness of Ra ≤ 0.08μm and a flatness error of ≤ 0.02mm/m, meeting high-precision processing requirements.
• Stable Structure & Strong Load-Bearing Capacity: The machine base and column are made of high-grade cast iron with aging treatment, which effectively eliminates internal stress, reduces deformation, and enhances structural stability. The worktable has a large bearing area (400×1000mm) and can carry workpieces weighing up to 500kg, adapting to large and heavy workpiece processing.
