Blade Material and Manufacturing Process
- Blade material is fundamental to determining blade lifespan. Blades made of ordinary steel are prone to wear and chipping when exposed to the thick rubber and potential metal impurities of truck tires.
- Blades made of high-strength alloys and subjected to strengthening processes such as quenching and tempering offer superior hardness and toughness, capable of withstanding the impact and friction of tire shearing, significantly extending their service life.
- Furthermore, the blade's cutting accuracy can also affect its lifespan. An unevenly ground cutting edge can lead to uneven shearing force, accelerated localized wear, and a shortened blade lifespan.

Thorough Material Pretreatment
- The pretreatment of truck tires directly affects blade wear. If hard impurities such as metal wheels and stones are not removed from the tires, these impurities will rub against the blades during shearing, causing scratches, curling, or even cracking.
- Heavy dirt, sand, and oil deposits on the tire surface can exacerbate wear between the blade and the material. Furthermore, the oil can corrode the blade surface and reduce its hardness.
- Conversely, removing the wheels in advance, cleaning impurities, and sorting the tires can reduce contact with foreign matter, avoid unnecessary wear, and extend blade lifespan.

Daily Operation Standards
- Operator standardization significantly impacts blade life. If the feed rate is too fast, tires can accumulate in the shear chamber, causing excessive shearing force on the blades and accelerating wear.
- Failure to adjust shear parameters based on tire thickness and hardness can result in a "cutting through" situation, necessitating repeated shearing, increasing blade-to-material contact time and further wear.
- Furthermore, if the equipment is not shut down promptly while idling, the idling friction of the blades can cause unnecessary wear and shorten their service life.

Frequency and Quality of Maintenance
- Regular maintenance is key to extending blade life. Failure to periodically inspect blades will prevent problems like edge wear and loosening, leading to increased wear.
- Failure to clean residual rubber debris and impurities from the blade surface after shearing can solidify, creating additional friction during the next shearing session and accelerating blade wear.
- Furthermore, failure to lubricate blade joints as required can increase friction between components, indirectly reducing blade life. Proper maintenance can promptly repair minor wear, prevent further problems, and ensure continued stable blade operation.
