135-25 straight column cutter is a core cutting tool designed specifically for heavy-duty mining machinery such as coal mining machines and tunneling machines. This product mainly solves the problem of frequent downtime caused by fast tool wear and high fracture rate during the excavation process of hard rock, coal seam, and semi coal rock tunnels. By optimizing the geometric structure and material ratio, the 135-25 straight column cutter can maintain stable cutting efficiency under high impact and high wear conditions, and is suitable for various fully mechanized mining faces and tunnel projects. It is a key vulnerable component to ensure continuous mining operations.

  This model of tooth cutter uses high-quality alloy steel as the base, and undergoes precision forging and heat treatment processes to ensure that the tooth body has extremely high toughness and bending strength. The head is embedded with high-quality hard alloy balls (alloy beans), and the diameter and joint surface are strictly controlled with tolerances to ensure that they do not fall off or break under high temperature and pressure. The implementation standard refers to MT/T240-1997 "Cutting Teeth for Coal Mining Machinery" and related industry specifications. Each batch of products has undergone hardness testing and flaw detection. The dimensional accuracy and material properties of 135-25 straight column cutting teeth meet the requirements of mining machinery matching, ensuring interchangeability and installation convenience.

  When selecting, special attention should be paid to the compatibility of equipment models. The 135-25 specification is usually suitable for specific models of coal mining machine drums or tunneling machine cutterheads. If the working condition is extremely hard rock (compressive strength greater than 80MPa), it is recommended to choose a variant model with a larger alloy head diameter or coating reinforcement; If it is soft coal or soil layer, the conventional 135-25 straight column cutter can meet the demand and has a better cost. Compared with ordinary conical cutters, the straight column structure has a tighter fit in the installation holes, stronger anti rotation ability, and is suitable for high-speed cutting scenarios. When purchasing, it is necessary to check the size of the tooth seat aperture and the card spring groove.

  When installing the 135-25 straight column tooth cutter, it is necessary to clean the debris inside the tooth seat, apply an appropriate amount of lubricating grease, ensure that the snap spring is installed in place, and prevent the tooth cutter from rotating or falling off during operation. In daily maintenance, the wear of the cutting teeth should be regularly checked. When the alloy head wears down to the substrate or shows obvious eccentric wear, it should be replaced in groups in a timely manner to avoid vibration caused by uneven force on the drum due to a single missing piece. Common failures include early fall off of the alloy head or fracture of the tooth body, which are mostly caused by excessive impact load or material defects. It is necessary to adjust the traction speed or optimize the spray dust suppression system in combination with the site geological conditions to reduce thermal stress.
