Domes of CNC Special Shape

- Appearance and Structure: A flange is added to the edge of a standard hemispherical base. This flange is typically a flat, ring-shaped structure with mounting holes. - Core Functions: Easy Installation and Sealing: Bolt holes on the flange allow the dome to be securely fastened to the equipment housing directly with screws. Provides a Sealing Surface: The flat surface of the flange mates with the sealing ring on the housing to achieve a reliable pressure seal or environmental seal. Increased Structural Strength: The flange structure enhances the strength of the dome's edge, enabling it to withstand greater installation torque and external pressure.

- Appearance and Structure: Grooves are machined into the surface of the dome (usually near the equator or a specific location). - Core Functions: Mounting and Positioning: Engages with retaining rings or locking rings within the equipment housing for quick installation and precise circumferential positioning. Preventing Rotation: Ensures the dome does not rotate accidentally within the equipment, crucial for directional optical systems.

- Appearance and Structure: Perforations are drilled at specific locations on the dome. - Core Functions: Sensor Integration: Provides a pathway for other non-optical sensors (such as temperature and pressure sensors). Pressure Balancing: In non-hermetic applications, it balances the air pressure inside and outside the dome to prevent fogging or deformation. Wiring Path: Provides a wiring path for internal heating elements or other electronic equipment. Mounting Assistance: Serves as locating pin holes to assist in installation.

- Appearance and Structure: A standard spherical edge is cut to create a non-spherical opening. Common methods include flat cutting (forming part of a cylinder) or beveling. - Core Functions: Space Adaptation: When installation space is limited, beveling allows it to adapt to a more compact equipment layout. Field of View Control: Intentionally cutting away part of the spherical surface limits unnecessary field of view, preventing the view of the equipment's own structure. Reference Surface Formation: The cut-out plane can serve as a mounting reference, facilitating positioning and bonding.
