Customer Challenges
Our customer is a manufacturer specializing in industrial automation equipment. They needed a critical connecting component for their high-precision pneumatic or hydraulic control systems. From the structure of the part shown in the image, it can be seen that it includes multiple holes, flat surfaces, and steps, with a relatively complex structure. The customer’s core pain points are as follows:
- Extremely high cutting efficiency: The part has a complex structure, and the customer needs to complete mass production quickly and efficiently.
- Excellent dimensional stability and surface finish: As part of the control system, the part must have precise dimensional tolerances and a smooth surface to ensure sealing performance and smooth fluid transmission—this requirement is also reflected in the smooth surface of the part in the image.
- Good corrosion resistance: The part may be used in humid environments or environments with corrosive fluids, so the material needs to have a certain level of corrosion resistance.
Our Solution: C360 Brass & Precision CNC Machining
To address these challenges, we provided the customer with a professional manufacturing solution: selecting C360 brass as the raw material and using our advanced CNC equipment for precision machining.
Material Selection: C360 Brass
- Advantages of “free-cutting brass”: C360 brass is one of the copper alloys with the best machinability available on the market. Its machining performance serves as the benchmark for measuring material workability (with a machinability rating of 100). This means the chips generated during cutting are small, easy to break, and do not easily wrap around the tool—greatly improving machining efficiency and surface quality. This can be intuitively seen from the fine structure and smooth surface of the part in the image.
- Comprehensive performance: In addition to its excellent machinability, C360 brass also has good corrosion resistance (performs well in the atmosphere, fresh water, and non-oxidizing acids), electrical conductivity (with a conductivity of approximately 56% IACS), and thermal conductivity (with a thermal conductivity of approximately 100 W/(m·K)). It is very suitable for manufacturing precision parts in electrical, mechanical, and fluid control systems, which is highly consistent with the application scenario of the part shown in the image.
Manufacturing Process: Precision CNC Machining
- Efficient production: We used high-speed CNC machining centers with a maximum spindle speed of 12,000 r/min and a maximum feed rate of 8,000 mm/min. By fully leveraging the excellent machinability of C360 brass, we achieved efficient and stable mass production. All holes, flat surfaces, milling, and drilling processes on the part can be completed in a single clamping, significantly shortening the delivery cycle and meeting the mass production needs of complex parts like the one shown in the image.
- High-precision control: Although brass itself is relatively soft, the precise structure of the part in the image shows that through precise tool path planning and strict parameter control, we ensured the part’s dimensional accuracy could reach ±0.01 mm, with a surface roughness Ra value ≤ 0.8 μm. All machined surfaces are smooth and burr-free, fully meeting the customer’s high-precision requirements.
RPS Value and Results
Through our precision CNC machining service for C360 brass, the customer gained the following core value:
- Win-win for cost and efficiency: The extremely high machining efficiency (with a single-shift production capacity of up to 500 pieces) and long tool life (one carbide tool can machine over 300 pieces) reduced the unit cost. This gave the customer a price advantage in the highly competitive market and enabled more efficient production of precision parts like the one shown in the image.
- Reliable performance: The high-precision dimensions (e.g., key fitting diameter tolerance controlled within ±0.01 mm) and smooth surface (Ra ≤ 0.8 μm) ensure the part operates stably in mechanical equipment with no leakage and high efficiency—and the structural design of the part in the image also helps it perform better.
- Customized service: From material selection to production manufacturing, we provided comprehensive professional advice to ensure the final product perfectly meets the customer’s application needs. Just like the part shown in the image, it accurately satisfies the usage requirements of specific mechanical equipment.
With our in-depth understanding of various metal materials and rich experience in precision machining, RPS successfully provided this key brass mechanical part for the customer—once again demonstrating our professional capabilities in the industrial manufacturing field.
