Compared with the single straight hole round bar, the manufacturing process of cemented carbide double straight hole round rods has some special requirements, which mainly include the following points:
- Raw material preparation: In addition to the preparation of cemented carbide raw material powder and the formulation of the mixed slurry, it is also necessary to pay attention to issues such as the particle size and drying effect of the raw material powder to ensure the quality of pressing and sintering.
- Pressing process: When pressing carbide double straight hole round bar blanks, attention needs to be paid to controlling parameters such as pressing pressure, pressure holding time, and pressure relief speed to ensure that the shape and size of the pressed blanks meet the requirements and to avoid cracks. , stomata and other problems.
- Forming mold: When making a double-straight-hole carbide round rod micro-hole forming mold, high-precision processing equipment and manufacturing technology are required to ensure the accuracy and stability of the mold. At the same time, attention should be paid to the selection and heat treatment of mold materials. craftsmanship to meet usage requirements.
- Sintering process: When sintering double straight hole cemented carbide round rods, parameters such as sintering temperature and time need to be strictly controlled to ensure that the sintered rods have excellent performance and organizational structure.
- Processing process: When processing double straight hole carbide round rods, attention must be paid to protecting the surface quality of the rods to avoid problems such as bumps and scratches. At the same time, attention should also be paid to requirements such as processing accuracy and surface roughness to meet the needs of different fields.
- Quality control: Quality control in the manufacturing process of cemented carbide double straight hole round rods is the key to ensuring product quality. It is necessary to ensure the overall quality of the product through quality inspection and monitoring of each link.
In short, the manufacturing process of cemented carbide double straight hole round rods has certain special requirements compared to single straight hole round rods. Various parameters and process conditions need to be strictly controlled during the manufacturing process to ensure product quality and performance.
