Applications of Shot Peening in Robotics and AI:
1. Flexsplines and gears of harmonic drives: Harmonic drives are the core components of robot joints. Their flexsplines and precision gears are subjected to high-frequency alternating loads in service and are highly prone to fatigue failure. Shot peening improves the fatigue strength of the flexspline, strengthening both the tooth root and the flank, and significantly extends the overall service life of the harmonic drive.
2. Shafts and transmission components: Various precision transmission components in robots—drive shafts, ball screws, guide rails, and others—also require shot peening to improve their fatigue resistance and wear resistance.
3. Shot blasting of robot bodies and structural parts: Robot bodies—chassis, base, joint arms, etc.—are mostly castings or forgings and require shot blasting during manufacturing.

We Understand Your Supply Requirements:
1. R&D and production of ultra-precision media: Components such as robot harmonic gears require fine-particle media (0.02–0.2 mm), placing extremely high demands on precise screening and classification capability.
2. Product consistency and traceability: Precision robot components demand extremely high reliability. Batch-to-batch consistency in hardness, particle size and chemical composition of blasting media is critical. Suppliers must establish a complete quality traceability system covering the full product lifecycle.
3. Media purity control: For lightweight materials such as aluminum and titanium alloys, iron-free media—stainless steel shot, ceramic media, etc.—is required. The media must have high purity and consistent sphericity.
4. End-to-end technical service: Suppliers must be able to provide blasting/peening solutions for different components—harmonics flexsplines, precision gears, aluminum alloy castings, and others. The supplier must offer professional testing of residual stress, roughness and coverage, and be able to help develop shot peening/blasting specifications and product warranty guidelines.

Tonglve metal's Solutions:
1. As a contributor to industry standards, Tonglve profoundly understands and observes the shot peening process requirements for robot transmission components such as precision gears and springs, so as to supply standard media.
2. Cut wire shot for gear peening—a core strength of Tonglve Cut wire shot is one of Tonglve’s core strength products. It covers a full hardness range of 40–65 HRC and particle sizes from 0.2 to 3.0 mm, meeting the needs of applications ranging from micron-level precision strengthening to routine cleaning.
3. Compared with cast steel shot, Tonglve’s cut wire shot offers irreplaceable advantages: no porosity, no shrinkage cavities, and a uniform structure—making it the best choice for shot peening precision gears, flexsplines, and similar components. Its surface is free of sharp corners and contains few fragments, so it does not damage precision workpieces. Its uniform particle size allows it to introduce a higher level of residual compressive stress.
4. Tonglve provides not only high-quality media but an integrated solution spanning R&D, manufacturing, sales, and service: professional shot blasting/peening process services for robot precision gears, flexsplines, springs, and other components; customized blasting/peening process solutions for harmonic drive flexsplines, precision gears, aluminum alloy castings, and other components; assistance in developing blasting/peening process specifications and product warranty guidelines; professional process testing for residual stress, roughness, and coverage; and frontier technical consulting and process optimization support through long-term collaboration with universities and research institutes.
