Precision Grinding

Achieving Ultimate Flatness and Dimensional Accuracy

1. Process Principles & Applications
Precision grinding is a machining process that uses a grinding wheel to meticulously abrade a workpiece's surface. Its primary goal is to enhance the flatness and dimensional accuracy of a component. This process is widely applied for surface finishing on precision parts such as molds, electronic device components, and inspection jigs.

2. Process Advantages

• Improved Surface Flatness: Eliminates surface unevenness, enhancing the quality of the product’s contact surfaces.
• Precise Thickness Control: Ideal for thin parts or components requiring tight thickness tolerances, ensuring uniformity.
• Corrects Heat Treatment Deformation: Grinding can remove deformation that may occur after metal heat treatment, ensuring the part remains flat and stable.
• Reduced Machining Stress: Fine surface finishing reduces residual stress on the part, extending its service life and durability.

Surface Finishing

Boosting Product Durability and Aesthetics

1. The Purpose of Surface Finishing
Surface finishing is the process of treating the surface of a metal part to enhance its properties, such as corrosion resistance, wear resistance, and appearance, thereby extending its service life.

2. Common Surface Finishing Methods

• Electroplating: Applies a thin layer of metal (e.g., chrome, nickel) to a surface, enhancing its corrosion resistance and appearance.
• Anodizing: Primarily for aluminum and its alloys, this electrolytic process forms a protective oxide film on the surface, improving corrosion resistance and hardness.
• Powder Coating/Painting: Applies a protective and decorative coating to the metal surface.

3. HIROKI's Professional Capabilities HIROKI offers a variety of surface finishing services and can select the most suitable method based on a product’s specific characteristics and client requirements. Our surface finishing expertise not only improves product performance but also strengthens its market competitiveness.
