High-Quality CNC Shot Peening Machine Factory & Factories

Shot blasting focuses on visual surface cleanliness—removing scale, rust, and surface contaminants. In contrast, CNC shot peening is an exact metallurgical cold-working process designed to induce controlled compressive residual stress layers. Peening demands strict real-time verification of blast pressure (±1 PSI), shot flow rate (±3%), nozzle standoff angle, and Almen intensity per SAE J442/J443. Every KOSHIN machine incorporates closed-loop telemetry to maintain repeatable saturation and coverage without damaging workpiece geometry.

Our CNC machines are purpose-built to satisfy aerospace computer-monitored peening specifications (AMS 2432B). The control architecture constantly monitors critical parameters: pneumatic pressure, media mass flow, part rotation, and nozzle translation speeds. If any parameter drifts outside pre-set safety tolerances, the system automatically pauses the cycle, retracts the nozzle, and generates an error flag. All operational data is saved into encrypted batch records for streamlined Nadcap audit readiness.

Yes. KOSHIN operates full-scale laboratory testing and contract development centers. Our engineering group generates empirical Almen saturation curves, performs coverage mapping studies, and evaluates X-ray diffraction (XRD) residual stress depth profiles on your test parts. Once parameters are verified, the exact CNC kinematic recipes are uploaded directly into your production machine prior to factory acceptance testing (FAT).

To size the right machine, our application engineers require: (1) Workpiece 3D CAD data or dimensions, material grade, and hardness; (2) Target areas for treatment and masking boundaries; (3) Specified Almen intensity range and coverage targets (e.g., 0.008-0.012A, 100% or 200%); (4) Media specifications (e.g., cut wire CCW14, cast steel S110, or ceramic beads); (5) Production volume requirements per shift; and (6) Factory footprint dimensions and pneumatic supply capacity.

We support installations across more than 50 countries. Every project includes structured Factory Acceptance Testing (FAT) at our production base, followed by on-site Site Acceptance Testing (SAT) led by our field service engineers. We conduct comprehensive training programs for maintenance personnel and operators covering machine programming, sensor calibration, Almen strip measurement, and routine preventative servicing.
