CNC milling machines, CNC lathes, and precision grinders are commonly used for machining sensor components. The machining process includes milling, turning, drilling, and grinding operations to achieve precise dimensions and shapes.

Common surface treatment methods include electroplating, coating, and anodizing. Electroplating provides corrosion resistance and aesthetic appeal, coating offers protective layers and color options, while anodizing enhances hardness and wear resistance of the material.

The specific material selection, equipment and processes involved, and surface treatment methods may vary depending on the type and application of the sensor.
