CNC precision machined non-standard brass valve bodies

Product Introduction

1. Material

The component in the image is made of Tin Bronze (common grades include QSn6.5-0.1, QSn10-1). This copper-based alloy, with tin as the primary alloying element, offers outstanding wear resistance, friction reduction, corrosion resistance, and mechanical strength, making it an ideal material for heavy-duty, high-precision mechanical parts.

2. Machining Process

· The core process is CNC machining, which includes turning, milling, drilling, and tapping to transform the tin bronze blank into a complex polyhedral structure with high-precision holes.

· The machining ensures the dimensional and positional accuracy of all mounting holes and locating surfaces, meeting the requirements for precision assembly and transmission.

· The surface retains the natural metallic luster of tin bronze without additional coatings, preserving the inherent texture and cutting marks from machining.

Applications of Machined Tin Bronze Products

· Bearings and Transmission Components: Sliding bearings, bushings, worm gears, and worms, leveraging their excellent anti-friction and wear-resistant properties.

· Hydraulic and Pneumatic Systems: Valve bodies, spools, and seal seats, relying on their good corrosion resistance and sealing performance.

· Marine and Offshore Engineering: Marine valves, pump bodies, and propeller components, which can resist seawater corrosion and heavy-duty operating conditions.

· Heavy Machinery: Wear-resistant bushings and gears for mining and metallurgical equipment, maintaining stability under impact and vibration.

· Instruments and Meters: Precision adjustment mechanisms and elastic elements, benefiting from their good elasticity and dimensional stability.

Advantages of Machined Tin Bronze Products

1. Excellent Wear and Friction Resistance: Maintains a low coefficient of friction even under oil-free or boundary lubrication conditions, effectively extending component lifespan.

2. Superior Corrosion Resistance: Provides excellent resistance to atmospheric, fresh water, seawater, and some chemical media.

3. Good Mechanical Properties: High strength and toughness, capable of withstanding significant impact and alternating loads.

4. High Machining Precision: CNC machining achieves micron-level precision, meeting the assembly and transmission requirements of precision machinery.

5. Good Casting and Machinability: Suitable for casting complex blanks and easy for subsequent precision machining, resulting in high yield rates.
