<\/span><\/span><\/div><\/div><\/div><\/div><\/div>SatrindTech blade resharpening is performed in our specialized machine shop, following controlled procedures and thorough preliminary inspections. Before beginning any work, we analyze the condition of the blade set to assess:<\/p>\n<\/div>
- <\/i><\/span>wear conditions and integrity<\/div><\/li>
- <\/i><\/span>presence of damage or deformation<\/div><\/li>
- <\/i><\/span>feasibility of the intervention<\/div><\/li>
- <\/i><\/span>number of remaining resharpenings compatible with specifications<\/div><\/li><\/ul>
The work is performed using computer numerical control (CNC) centers<\/strong> to ensure high-quality and repeatable grinding. The objective is not to simply “touch up” the blades, but to restore the original conditions<\/strong> of the entire blade pack, including profiles and cutting edges<\/strong>, in accordance with design geometries. <\/p>\nTo maintain geometric specifications, the operation is completed with the addition of necessary components (such as spacers and cleaning sectors<\/strong>) that compensate for the millimeters of material removed during sharpening.<\/p>\n<\/div><\/div><\/div>
