Suzhou Krosino Mechatronic Technology Co., Ltd. provides expert CNC machining for industrial flanges and shaft couplings. These components are critical for sealing and torque transmission; therefore, we prioritize geometric precision, bolt-hole pattern accuracy, and perfect face alignment. Our manufacturing process ensures that your coupling interfaces and flange seals are optimized for high-pressure and high-load environments.
Successful performance in sealing and power transmission requires strict control over flatness and concentricity. We use multi-axis CNC turning and milling to ensure these interfaces meet your rigorous assembly standards.
| Component Feature | Typical Functional Tolerance |
|---|---|
| Flange Face Flatness | ±0.02mm to ±0.05mm (Ensures leak-free seals) |
| Bolt-Hole Pattern Pitch | ±0.05mm (Ensures easy and secure fastening) |
| Coupling Bore Concentricity | 0.01mm - 0.03mm (Prevents shaft vibration) |
Q1: How do you guarantee seal integrity on flange faces?
We employ precision CNC facing processes to achieve specified surface finishes (Ra values) and flatness tolerances. This creates an ideal mating surface for gaskets and O-rings, preventing fluid or pressure leaks in high-stakes applications.
Q2: What materials are typical for high-torque couplings?
We commonly machine alloy steels like 40Cr and 42CrMo for high-torque applications, as they offer the necessary yield strength and wear resistance. For corrosive environments, we can provide stainless steel solutions (304/316L) to ensure longevity.
Q3: How do you ensure bolt-hole alignment for large batches?
We utilize CNC indexing and programmed drilling paths, which eliminate human error found in manual layouts. Every piece in a batch is machined using the same programmed coordinates, guaranteeing interchangeability and seamless installation for your assembly team.
