Hongxin Precision offers one-stop custom machining services for high-precision bearing housings and transmission flange assemblies. Leveraging advanced turn-mill composite machining technology, we manufacture critical support components for the semiconductor equipment, automation systems, and precision machinery sectors.

Whether the requirement calls for high-strength, corrosion-resistant stainless steel structures or lightweight aluminum alloy assemblies, we deliver high-precision manufacturing that ensures exceptional concentricity and repeatable positioning performance—even in high-speed operating environments.

• High-Precision Bearing Seat Tolerance Control: Addressing the critical need for precise bearing fit, Hongxin Precision employs precision CNC boring and grinding processes to consistently maintain internal bore tolerances within the H7-H8 grade range. By strictly controlling mating dimensions, we achieve precise interference or clearance fits, effectively reducing operational vibration and noise while extending the overall service life of the equipment.
• Integrated Turn-Mill Machining Capabilities: Utilizing multi-axis simultaneous machining equipment, we complete the precision machining of stepped bores, counterbored holes, and complex structural features in a single setup, thereby eliminating the cumulative errors associated with multiple setups. This fundamentally guarantees the coaxiality and perpendicularity of the bearing seat relative to the flange face, enhancing the overall assembly precision and stability of the machine.
• Multi-Material Compatibility & Surface Hardening Treatments: We support the machining of a wide range of engineering materials, including SUS304/316L stainless steel, aerospace-grade aluminum alloys, and copper alloys. Depending on the specific application environment, we offer various surface treatment solutions—such as hard anodizing, electropolishing, and electroless nickel plating—to significantly enhance the parts' wear resistance, corrosion resistance, and chemical stability.
• Full-Process Digital Inspection & Quality Traceability: All products undergo critical dimensional inspection using high-precision Coordinate Measuring Machines (CMM), with a specific focus on verifying core metrics such as concentricity and positional accuracy. Every delivered batch is accompanied by Material Test Reports (MTR) and comprehensive dimensional inspection data, ensuring full-process traceability and guaranteeing high assembly yields and long-term stability for our products.

All our CNC machined parts come with complete inspection reports and material certifications. We offer comprehensive after-sales service, including technical support, rework when necessary, and timely handling of any quality issues.

We use standard export wooden crates or custom packaging according to your requirements, and support air, sea, or express shipping. If you have any questions about the products, please feel free to contact our technical team.
