Technical Overview

Ultra Fine Steel Shot is a super-fine particle blasting medium developed by LuXing Metal for precision surface treatment. Made from premium high-carbon steel via advanced atomization, it delivers excellent sphericity, uniform particle distribution, and soft impact characteristics. Compared to standard steel shot, ultra fine shot features significantly smaller diameters (0.1–0.7 mm), enabling deep penetration into micro-holes, narrow gaps, and complex internal cavities — making it irreplaceable in precision component processing.

Core Technical Features

Feature	Description
Ultra-Fine Particles	Reaches narrow gaps, micro-holes, and complex cavities inaccessible to conventional media
Soft Impact	Low surface roughness (RA), safe for thin-walled and precision substrates
Uniform Size Distribution	Tight particle size control ensures batch-to-batch consistency
Extended Durability	High density, crush-resistant — far greater recycling cycles than non-metallic media
Refined Finish	Delivers a smooth, satin-like surface without excessive erosion

Application Fields

1. Precision Shot Peening

Precision springs (watch mainsprings, micro valve springs, electronic connector elastic components)
Micro gears, micro bearings, precision transmission parts — fatigue life enhancement
Medical implants, orthopedic instruments, dental implant surface strengthening

2. Micro Deburring

Precision machined edge micro-burr removal (preserves edge sharpness)
Hydraulic / pneumatic precision valve body cross-hole deburring
Electronic connectors, contact terminals — precision deburring

3. Thin-Walled Parts Finishing

Thin-walled tubes, bellows, metal diaphragms — internal & external finishing
Precision casting surface cleaning (preserves casting contour accuracy)
Watch & clock precision components — matte / satin finishing

4. Fine Internal Cavity Cleaning

Fuel nozzles, carburetor internal channel cleaning
Mold cooling channels, vent micro-hole de-clogging
3D-printed metal parts — residual powder & support structure removal
Heat exchanger micro-tube inner wall oxide scale cleaning

5. Robotics & Automation (Fast-Growing Sector)

Collaborative robot precision joint gears, harmonic drive flexspline strengthening
Industrial robot end-effectors (grippers, suction cup connectors) finishing
Service robot precision drive components — deburring & surface refinement
Surgical robot micro-instruments surface treatment
Machine vision system precision mounts, sensor housings — matte finishing

Contraindications

Strictly prohibited for heavy rust removal, thick coating stripping, casting riser/cut-off mark grinding, or any high-impact operations — use steel grit or chilled iron grit instead.

Core Technical Advantages

Secondary Quenching Process

After primary centrifugal quenching, we apply a second hardening cycle. This creates a denser microstructure, significantly inhibiting carbon deviation. The result: 1.3× longer service life, lower breakage rate, less dust, better elasticity and faster cleaning speed.
