The 135-30 straight column cutter is a core rock breaking tool designed specifically for heavy mining machinery such as coal mining machines and tunneling machines. This category mainly solves the problem of efficient crushing of materials in high hardness coal seams or semi coal rock tunnels, and is suitable for longwall coal mining working faces and tunnel excavation conditions. As a direct contact component connecting the drum and coal rock, the 135-30 straight column tooth is subjected to enormous impact loads and wear through its specific geometric structure, ensuring the cutting efficiency and stability of the equipment during continuous operation. It is an indispensable key vulnerable component in coal and non coal mining systems.

  The 135-30 straight column cutting teeth are made of high-quality alloy steel substrate, with high-purity tungsten carbide alloy heads (commonly known as alloy beans) embedded in the head, and firmly bonded through vacuum brazing technology. Its overall length, handle diameter, and alloy head protrusion height strictly follow the 135-30 model standard to ensure precise fit with the coal mining machine tooth seat. The product complies with relevant mining machinery industry standards and undergoes strict heat treatment processes to enhance matrix toughness and wear resistance. The alloy head has extremely high compressive strength and red hardness, which can maintain sharp cutting edges in high temperature, high dust, and strong impact environments, extending single use life.

  When selecting 135-30 straight column cutting teeth, it is important to confirm whether the specifications of the tooth seat of the coal mining machine drum match the size of the handle and the position of the clamp groove of the model. This model is suitable for complex geological conditions ranging from medium hard to hard coal seams and some containing gangue. If the working conditions are extremely hard rocks or whole rock tunnels, it is recommended to evaluate whether higher strength irregular cutters or variants with different alloy ratios are needed. Compared with ordinary conical cutters, 135-30 straight column cutters have better chip removal performance and self sharpening under specific drum layouts. When purchasing, it is necessary to check the original equipment drawings to avoid installation difficulties or detachment during operation due to dimensional deviations.

  Before installing the 135-30 straight column tooth cutter, the internal debris of the tooth seat should be cleaned, and the elasticity of the retaining spring should be checked to ensure that the tooth cutter is inserted in place and locked firmly, preventing it from loosening due to vibration during operation. In daily maintenance, it is necessary to regularly inspect the wear of the cutting teeth. When the alloy head is worn flat or the substrate is severely deformed, it should be replaced in groups in a timely manner to maintain the balance of the roller's force and avoid eccentric wear and damage to the tooth seat. Common faults include alloy head detachment or substrate fracture, often caused by welding defects or encountering unbreakable foreign objects. If abnormalities are found, the machine should be stopped immediately for troubleshooting, optimizing the mining process to reduce abnormal losses and ensure continuous and efficient production of the mine.
