Surface roughness and surface finish are important indicators for measuring the surface quality of parts, and they play a vital role in the CNC machining manufacturing industry. Surface roughness focuses on the microscopic geometry of the part surface, while surface finish focuses more on the smoothness and appearance of the surface.

A threaded hole is a hole with spiral lines on the inner wall of the hole. This hole is often used to connect or fix parts such as bolts and nuts. Tapping is the process of creating internal threads. Understanding the difference between tapping and threading is crucial for any CNC machining project.

Insert molding technology is a technology that embeds inserts made of metal, plastic or other materials into plastic or other base materials to form a composite structure. Understanding the process flow, design points and applications of insert molding can help manufacturers better apply this technology in different industries.

Brushing is a process of producing fine textures or lines by rubbing or scraping the surface of a material through mechanical means such as rollers, brushes or special mechanical tools. In-depth exploration of brushing surface treatment and precise application based on the characteristics of different materials can help enhance the visual effect of the product.

Metal materials such as brass, bronze and copper play an important role in the field of CNC machining. In-depth exploration of the differences and distinctions between brass, bronze and copper, and through in-depth understanding of their characteristics and application range, we can make the best material selection for metal projects.
