Surface grinder M7140H

Core Application Scenarios

The M7140H is a heavy-duty horizontal surface grinder designed for precision grinding of flat surfaces of medium and large-sized workpieces. It features strong rigidity and high processing accuracy, widely used in mold manufacturing, machinery parts processing, tool production, and hardware manufacturing industries.
  • Mold & Die Processing: Specializes in grinding flat surfaces of mold bases, die plates, and precision molds made of mold steel, ensuring uniform surface finish and tight dimensional tolerance to meet mold assembly requirements.
  • Mechanical Parts Finishing: Ideal for grinding flat surfaces of flange plates, connecting plates, and precision hardware parts, improving the surface quality and matching accuracy of components.
  • Batch Production of Flat Parts: Equipped with a rectangular electromagnetic chuck for quick workpiece clamping, it supports efficient batch processing of standardized flat parts, balancing precision and production efficiency.
  • Maintenance & Repair: Suitable for grinding and repairing worn flat surfaces of mechanical parts, restoring their original flatness and dimensional accuracy.

Batch Advantages of Equipment

  • High Precision & Stability: The reinforced cast iron bed and precision linear guide rails ensure stable operation during heavy grinding, maintaining consistent processing accuracy.
  • Heavy-Duty Performance: With a maximum workpiece weight of 800 kg, it handles heavy workpieces easily, meeting the processing needs of mold and heavy machinery parts.
  • Easy Operation & Clamping: The electromagnetic chuck enables fast loading and unloading of workpieces; the manual control system with clear markings is user-friendly for operators of all skill levels.
  • Cost-Effective: As a used grinder, it costs only 30%-50% of new models, providing small and medium-sized enterprises with a cost-efficient solution for high-precision flat grinding.
