1. Consider the hardness and toughness of the material: For materials with high hardness and strong toughness, such as industrial rubber, you can choose a sharp and wear-resistant carbide tool, and increase the slitting pressure appropriately to ensure that the tool can smoothly cut into the material to avoid slitting size deviation due to large cutting resistance. For soft and easily deformed materials such as silk, it is necessary to reduce the slitting pressure, use a tool with a thinner and sharper blade, and reduce the slitting speed to prevent the material from shifting or stretching during the slitting process.
2. Pay attention to the thickness and elasticity of the material: For materials of different thicknesses, adjust the tool height and cutting depth of the slitting machine. For thicker materials, the tool needs to be adjusted to the appropriate height to ensure complete cutting; for thinner materials, the cutting depth must be accurately controlled to avoid over-cutting. For materials with high elasticity, such as sponges, the tension must be accurately controlled during slitting. Excessive tension can easily stretch the material, and too little tension will cause the material to wrinkle, affecting the slitting accuracy. The optimal tension value can be found through multiple tests.
3. Based on the surface characteristics of the material: Smooth-surfaced materials, such as plastic films, are prone to slipping during slitting. You can increase the friction of the conveyor belt or use a vacuum adsorption device to fix the material to ensure that the material is in a stable position during the slitting process. For materials with rough surfaces, such as felt, pay attention to the wear of the tool and replace the tool in time to prevent uneven slitting edges due to tool wear, which affects the slitting accuracy.
