The type of steel used for manufacturing is a key factor in the durability of the final product. High quality wear-resistant alloy steel with high wear resistance and durability shall be selected, including 40Cr, 20CrMn, stainless steel, etc.
Before drilling, the round bar is cut and turned to a specific diameter and thickness, and then the dimensional tolerance and surface quality are checked. After successful measurement and testing, we receive a unique product number and have detailed technical documents to track each stage of the production process.
Before drilling, it is necessary to select the geometric shape and proper length of the hole. In order to ensure high accuracy and obtain the maximum hole flatness, high-quality drill bits are required.
The depth and angle of the counterbore will depend on the granulating material, and these parameters are key factors for the quality of the final product.
The hardness of heat treatment is HRC55-66, which has good durability, so as to improve its wear resistance and productivity. The heat treatment process shall be carried out with appropriate parameters for materials to ensure maximum hardness and appropriate resistance to eliminate the risk of cracking.
High quality products should have perfectly smooth and countersunk holes. Hammer adopts Italian imported drilling and advanced vacuum heat treatment process to avoid oxidation of horizontal holes, effectively ensure the smoothness of mold holes, and the granulated products are first-class.
In order to maintain the high quality of the granulator, the manufacturing process must be continuously supervised, and each production process must be strictly monitored to reduce the number of defective products.
