Part Structure Description

1. Square Flange Housing / Mounting Base

Features four mounting holes, internal stepped cavities, and sealing groove designs. Suitable for sealing ring assembly.

Applications include instrument housings, sensor bases, and motor end covers.

Ensures precise positioning and reliable sealing performance.

Flange surface parallelism can be controlled within ≤0.02mm.

2. Multi-Step Cylindrical Sleeve Housing

Designed with multi-level stepped internal cavities, positioning structures, and multiple grooves for internal component fixation.

Used for precision positioning and assembly of internal components.

Coaxiality can be controlled within ≤0.03mm, ensuring accurate alignment of internal parts.

3. Lightweight Hollow Flange Ring

Ring-shaped flange structure with distributed mounting holes and lightweight cut-out grooves.

Reduces component weight while maintaining structural strength.

Suitable for:

• Spacer rings

• Bearing retaining rings

• Connection flanges

Ideal for lightweight equipment applications.

4. Tapered Diameter Adapter Housing

Features variable-diameter cavity structures with internal and external threads.

Manufactured through CNC mill-turn processes to achieve seamless transitions between cavities and pipelines.

Suitable for space-limited assembly applications.

5. Sealing Plates & Thin Flange Washers

Available in square or round designs with reserved O-ring sealing grooves.

Used for compressing sealing components.

Groove dimensions are precisely matched with standard O-rings to ensure dust-proof and leak-proof performance.

6. Positioning Key Blocks

Small flat key components designed for transmission positioning.

Used together with shaft components to transmit torque and ensure accurate mechanical positioning.

Product Advantages

High Precision Control

Mill-turn machining enables one-time clamping and forming, reducing fixture positioning errors.

Critical geometric tolerances, including:

• Coaxiality

• Parallelism

• Perpendicularity

are strictly controlled throughout production.

Strong Structural Compatibility

Supports complex structures including:

• Deep cavities

• Irregular shapes

• Lightweight hollow structures

• Sealing grooves

• Internal and external threads

• Multi-step composite designs

Turning, milling, tapping, and slotting can all be completed through one-stop machining.
