Détails du produit
La grenaille d'acier coupée est fabriquée en découpant des fils d'acier de haute qualité en granulés uniformes. En fonction du procédé de fabrication, elle peut être proposée sous deux formes principales : la grenaille cylindrique et la grenaille sphérique (grenaille arrondie). Grâce à une technologie d'arrondissage de pointe, les arêtes coupées sont éliminées, ce qui permet d'obtenir une grenaille lisse et résistante.
Caractéristiques
Dureté élevée – Généralement supérieure à 50 HRC, bien plus dure que les billes en acier moulé classiques, garantissant des performances de grenaillage très efficaces.
Résistance et longue durée de vie – Une microstructure homogène et une excellente résistance à la fatigue garantissent une durée de vie plus longue.
Forme homogène – Disponible en versions cylindrique et sphérique, garantissant une qualité de sablage constante.
Gamme de dimensions – Dimensions standard allant de CW1,0 mm à CW3,0 mm ; des dimensions sur mesure sont disponibles sur demande.

Applications du produit
Grinding shots are forged to eliminate voids, cracks, and breakage, ensuring durability during use. In operation, their shape gradually wears down and becomes smaller. Once the size is reduced to less than 30% of the original, the shots are automatically removed by the dust removal and separation systems of the blasting machine, completing their service life cycle.
As a subcategory of steel wire cut shot, grinding steel shots are produced by cutting steel wire into cylinders with equal diameter and length, then rounding the sharp edges to form spherical particles. This process gives them the combined advantages of both cast steel shots and steel cut wire: uniform grinding, no damage to the workpiece, high wear resistance, and long service life. They are widely used in precision processing industries, especially for automotive and motorcycle parts, where they provide excellent surface finishing and strengthening results.
With a mature and standardized production process, grinding steel shots are free of internal pores and feature highly uniform particle sizes. Their short blasting cycle improves efficiency, while maintaining consistent quality. In industrial applications, they are ideal for components such as quenched gears, screws, springs, chains, stamping parts, stainless steel pieces, and other high-hardness workpieces. They effectively remove oxides, perform surface strengthening, achieve dust-free blasting, and highlight the metallic luster of the product.
