The composition of YG6X carbide scoring wheel mainly includes the following parts:
1. Main metal content:
WC (tungsten carbide): 93.5% or 94%, is the main component of YG6X cemented carbide, which determines its hardness and wear resistance.
Co (cobalt): 6%, is an important binder for YG6X cemented carbide, which can improve the impact resistance and toughness of the alloy.
2. Impurity content:
Ni (nickel) and other impurities: low content, usually no more than 0.5%.
3. Mechanical properties:
Density: about 14.5-15.0g/cm³.
Hardness (HRA): can reach 91 or 90HRA or above.
Flexural strength (σbb/MPa): about 1400-1500MPa.
Impact toughness σK/(J/cm²): 2.5.
Machining carbide scoring wheels is a process that involves multiple steps and details. Here's a clear process that incorporates the relevant information from the reference article:
First, Preliminary preparation
Preparation of alloy bars: select bars with appropriate hardness according to the customer's requirements. Cemented carbide is made of tungsten carbide, titanium carbide and other metals as the hard phase, cobalt and other metals as the binder, through the method of powder metallurgy, with high hardness and low thermal conductivity.
Selection of process card: cut according to the corresponding process card to ensure that the material meets the processing requirements.
Second, the processing process
Pressing: Pressing with punches and dies in an automated press to obtain basic shapes and dimensions. This step is the key to ensuring the shape of the scoring wheel foundation.
Sintering: Through the sintering process, the melted cobalt is bonded with tungsten carbide particles, which further enhances the hardness and stability of the scoring wheel.
Grinding: Diamond grinding is used to give the carbide insert an accurate shape. During the grinding process, it is necessary to select the right grinding wheel and grinding parameters to avoid tool wear and loss of machined surface quality. At the same time, it is necessary to pay attention to the occurrence of grinding cracks, which are usually caused by the tensile stress formed on the surface of the tool that exceeds the tensile limit of the material. Therefore, the source of tensile stress should be strictly controlled during the grinding process.
Cutting edge treatment: The cutting edge is treated to obtain the correct shape to achieve the maximum wear resistance required for machining. This step is essential to improve the cutting performance and durability of the cutter wheel.
Third, Post-processing
Coatings: Chemical vapor deposition and physical vapor deposition are the two coating methods available, depending on the material and processing method. The coating can enhance the wear resistance and corrosion resistance of the scoring wheel, prolonging its service life.
Quality inspection: The quality inspection of the processed cemented carbide cutter wheel is carried out to ensure that it meets the design requirements and use requirements.
Forth, Precautions
During the whole processing process, it is necessary to pay attention to safe operation to avoid accidents.
Strictly control the processing parameters and process requirements to ensure the quality and performance of the scoring wheel.
Regularly check the status of equipment and tools, and replace seriously worn parts in time to ensure machining accuracy and efficiency.
Through the strict implementation of the above steps and precautions, the high-quality machining and long-term use performance of the cemented carbide scoring wheel can be ensured.
