18CrNiMo7-6 Forged Steel Blanks For Input Optical Shafts. 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 shaft, 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.

Product Features

• Superior Internal Structure: Forging refines the steel's grain, eliminating defects for exceptional toughness and fatigue resistance.
• Optimal Machining Foundation: Blanks are designed for efficient and precise machining to achieve exact dimensions and finishes.
• Enhanced Durability: Forging provides inherent strength to withstand significant stresses, leading to extended operational life.
• Customizable for Needs: Available in various steel grades and tailored dimensions to suit unique shaft designs.
• Reliable Performance Base: Provides a consistent material foundation crucial for precision and longevity.

Application Scenarios

These steel forging blanks are essential precursors for shafts in a diverse range of demanding industrial and high-tech applications:

• Input Optical Axis Blanks: For shafts driving or supporting optical elements in precision optical instruments, laser systems, and metrology equipment.
• Upper Transmission Shaft Blanks: Used for shafts in industrial gearboxes (heavy machinery, wind turbines, marine propulsion), power generation equipment, and vehicle drivetrains.
• Lower Rotating Shaft Blanks: Material for robust shafts in heavy industrial machinery (conveyors, crushers), mining and construction equipment, and hydraulic/pumping systems operating under constant heavy loads.

The steel forgings production flow:

raw material inspection → unloading → inspection → preheating → forging → heat treatment → inspection → rough machining → non-destructive testing → inspection → packaging → delivery.
