Steel Forging Blank For Input Optical Axis, Upper Transmission Shaft And Lower Rotating Shaft. Our steel forging blanks are specialized, high-performance starting materials for critical components in mechanical and optical-mechanical systems. We provide robust blanks for input optical axes, upper transmission shafts, and lower rotating shafts, all crafted through precision forging. This ensures the final machined components will have superior strength and dimensional stability for high-precision, high-speed, and heavy-load applications.
These steel forging blanks are essential precursors for shafts in a diverse range of demanding industrial and high-tech applications:

|---|---|
| Product Name | Steel Forging Blank For Input Optical Axis, Upper Transmission Shaft And Lower Rotating Shaft |
| Material Grades | - High-grade carbon and alloy steels: 45# ,35#42CrMo4 18CrNiMo7-6 - Optimized for tensile strength, wear resistance, and shaft performance - Suitable for dynamic load and rotational applications |
| Forging Equipment | - Hydraulic hammers: 5T / 8T / 12T - Open-die forging press for shaft configurations - Supports large-diameter shaft blanks with directional grain control |
| Manufacturing Process | Hot Forging → Heat Treatment → Precision Rough Machining → Dimensional & Surface Inspection → Optional Finish Machining |
| Forging Ratio | ≥ 3.0 — Our process refines the material, creating a fine grain structure that ensures exceptional fatigue resistance even under continuous cyclic torsional stress. |
| Applications | - Drive shafts, motor shafts, transmission shafts - Gearbox shafts, roller shafts, and spindle components - Widely used in industrial equipment, pumps, compressors, and heavy-duty machinery |
| Heat Treatment Options | - Tempered for optimal mechanical performance - Optional stress-relieving to improve dimensional stability before final machining |
| Testing & Inspection | - Chemical: Spectrometer-based alloy composition check - Mechanical: Tensile, yield, hardness, and impact testing - NDT: Ultrasonic Testing (UT) for core integrity - Dimensional: Length, diameter, straightness, and concentricity checks |
| Value-Added Services | - Your Shaft, Your Way: Pre-Machined, Protected, and Trackable: We deliver shafts with custom lengths, diameters, and stepped geometries, featuring pre-machined journals and shoulders to speed up your assembly. Our thorough packaging protects against corrosion and damage during transit. Benefit from traceable laser marking and optional OEM branding. |
The steel forgings production flow:
raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
