Our Precision Machined Steel Parts Processing Flow:

1.Precision Fixturing & Positioning for Steel Workpieces: Tailored fixture systems are engineered to address steel’s high rigidity and machining forces, ensuring stable clamping and micron-level positioning accuracy of steel workpieces on machine tools. This eliminates deformation-induced errors during heavy-duty machining, laying a solid foundation for consistent precision in steel parts.

2.Efficient Multi-Process Integrated Machining for Steel: Leveraging high-performance 3-axis/4-axis/5-axis machining centers and turn-mill composites (from world-renowned brands like Brother, Haas, and BAOJI, with a precision tolerance of ±0.001 mm), we complete complex steel machining processes—including milling, turning, drilling, and thread cutting—in one setup. For high-hardness or thick-walled steel parts, this integrated approach reduces workpiece handling by 30%, shortens cycle times by an average of 20%, and minimizes cumulative errors from repeated clamping.

3.Real-Time Monitoring for Steel Machining Stability: Operators monitor cutting parameters (such as spindle speed, feed rate, and tool wear) in real time, especially critical for heat-treated or high-carbon steel parts prone to hardening. This proactive oversight prevents tool breakage, ensures uniform surface finishes, and maintains stable machining quality throughout the steel part production process.

4.Comprehensive Quality Inspection for Steel Performance: Quality is paramount in precision steel machining. Post-production, we employ advanced testing equipment—including Serein coordinate measuring machines (CMM), Mitutoyo precision gauges, 2D height measurement systems, go/no-go gauges, Rockwell/Brinell hardness testers, digital micrometers, 2.5D projectors, and X-ray spectrum analyzers—to conduct 100% full inspections. Key steel-specific parameters are verified: dimensional accuracy, tolerance compliance, surface roughness (Ra/Rz), hardness (to confirm heat treatment effectiveness), tensile strength, and corrosion resistance (for surface-treated steel parts). This rigorous testing minimizes assembly mismatches and slashes rework costs for steel components.

5.Steel-Specific Post-Processing & On-Time Delivery: We provide specialized post-processing for steel parts, including precision deburring (critical for eliminating sharp edges in load-bearing steel components), ultrasonic cleaning to remove machining residues, and customized surface treatments (such as electroplating for corrosion resistance, black oxide coating for wear resistance, sandblasting for texture uniformity, and painting for aesthetic or environmental protection). After thorough cleaning and rust-proof packaging (or custom packaging as required), finished precision machined steel parts are delivered with an on-time rate exceeding 99.5%.
