The flexibility design of resin cutting polishing disc polishing grinding disc is the key to improving the polishing effect of complex curved surfaces. Through material property adjustment, structural optimization and process innovation, the grinding disc can closely fit the contour of the curved surface and achieve uniform and efficient polishing. In terms of material selection, it is necessary to break through the limitations of traditional hard grinding discs. Ordinary grinding discs are hard in texture. When contacting complex curved surfaces, it is difficult for them to fully fit the concave and convex changes of the curved surface, which is prone to problems such as excessive local pressure or polishing blind spots. Flexible grinding discs use elastic resin as a binder. This resin has good deformation ability and can adaptively fit the shape of the curved surface under pressure, ensuring that the contact area between the grinding disc and the workpiece surface remains stable at all times, avoiding surface damage or uneven polishing caused by local over-polishing.
The internal structure design of resin cutting polishing disc polishing grinding disc also has an important impact on flexibility and polishing effect. To enhance flexibility, a honeycomb or grid-shaped internal structure can be used. This structure not only ensures the basic strength of the grinding disc, but also gives it better elastic deformation space. When the grinding disc contacts a complex curved surface, these special structures can compress and rebound like a spring, and flexibly adjust their shape as the curvature of the curved surface changes. For example, when polishing a workpiece with a special-shaped structure such as a circular arc or a groove, the honeycomb structure of the grinding disc will automatically shrink in the convex part and naturally stretch in the concave part, always maintaining close contact with the curved surface, thereby achieving uniform polishing of the entire curved surface and eliminating the polishing dead angle that is easy to produce with traditional hard grinding discs.
Processing is the key link in achieving a balance between flexibility and polishing performance. In the process of making grinding discs, the flexibility of the grinding disc can be precisely adjusted by controlling the curing degree of the resin binder and the ratio of additives. Resin binders with a lower degree of curing can make the grinding disc softer, but excessive softness will affect the wear resistance and cutting force of the grinding disc; conversely, excessive curing will reduce flexibility. Therefore, it is necessary to find the best combination of process parameters through repeated experiments and optimization. At the same time, adding an appropriate amount of plasticizer or elastic fiber to the grinding disc can further improve its flexibility and tear resistance. These additives will not only not weaken the grinding ability of the grinding disc, but also play a buffering role during the polishing process, reducing scratches and damage caused by the hard friction between the grinding disc and the curved surface.
The advantage of flexible resin cutting polishing disc polishing grinding disc in polishing complex curved surfaces is also reflected in the uniformity of pressure distribution. When polishing curved surfaces, traditional hard grinding discs cannot fit completely, which easily leads to pressure concentration in local areas, causing over-polishing in the area and insufficient polishing in other areas. Flexible grinding discs, with their good deformation ability, can evenly distribute the polishing pressure on the entire contact surface. When the grinding disc contacts the curved surface, the elastic material will automatically adjust the pressure according to the ups and downs of the curved surface, apply less pressure on the convex parts, and appropriately increase the pressure on the concave parts to ensure that the entire curved surface can be properly polished, so as to obtain a consistent surface finish.
The convenience of operation during use is also a major feature of flexible grinding discs. Due to its good flexibility, this type of grinding disc is more convenient to install and replace, and can quickly adapt to polishing equipment and workpiece fixtures of different shapes.
When polishing complex surfaces, operators do not need to adjust the angle and pressure frequently like using hard grinding discs. They only need to maintain normal polishing speed and strength, and the grinding disc can automatically adapt to the changes in the surface, greatly reducing the difficulty of operation and labor intensity. At the same time, the flexible grinding disc produces less vibration during the polishing process, which can reduce the wear and noise of the equipment, extend the service life of the equipment, and improve the comfort of the working environment.
The durability of the flexible resin cutting polishing disc and polishing grinding disc should not be ignored. Although flexibility is emphasized, this type of grinding disc can still maintain good wear resistance and fatigue resistance through reasonable material formulation and process design. The elastic resin binder forms a strong bond with the abrasive particles, and the abrasive will not fall off easily even during frequent deformation. At the same time, the special structural design helps to disperse the stress during the polishing process, avoid cracks or damage to the grinding disc due to excessive local force, and ensure that the grinding disc always maintains a stable polishing effect during long-term use.
The research and development and application of flexible resin cutting polishing disc and polishing grinding disc is a process of continuous innovation and optimization. With the development of material science and manufacturing technology, new elastic materials and structural designs are constantly emerging, providing more possibilities for improving the polishing effect of complex curved surfaces. By combining advanced simulation technology, the stress and deformation state of the abrasive disc during the polishing process of different curved surfaces can be simulated and analyzed, which can optimize the design plan in advance, shorten the R&D cycle, and promote the widespread application and sustainable development of flexible abrasive discs in the field of complex curved surface polishing.
