As an important fixture, Spring collet has its own unique application characteristics in different machining fields.
1. Turning Processing Field
In turning processing, Spring collet is mainly used to clamp circular workpieces. Since the workpiece needs to rotate at high speed during turning, the concentricity of the chuck is extremely high. Spring collet can provide good concentricity to ensure the stability of the workpiece during rotation, so that the outer cylindrical surface turned out has high precision and low roughness. Moreover, the diameter range of the workpiece for turning processing is relatively wide, and Spring collet can adapt to workpieces of different diameters through its own elastic deformation. For some slender shaft workpieces, the uniform clamping force of Spring collet can prevent the workpiece from deforming during processing. For example, when precision turning small-diameter shaft parts, Spring collet can accurately fix the workpiece and achieve micron-level processing accuracy.
2. Milling Processing Field
Milling involves the processing of various features such as planes, contours and grooves of the workpiece. The application of Spring collet in milling is different from turning. During milling, the workpiece is not only subjected to the cutting force of the rotating tool, but also may be subjected to axial and radial forces. Spring collet needs to have sufficient clamping force to resist these forces and prevent the workpiece from being displaced during processing. In addition, milling may involve workpieces of complex shapes, and the versatility of Spring collet allows it to adapt to different shapes of connection parts. For example, when processing mold parts with cylindrical shanks, Spring collet can quickly clamp the workpiece, facilitating milling operations of various contours. However, due to the large milling force and variable direction, the strength and rigidity requirements of Spring collet are relatively high to ensure that there will be no loosening or deformation during long-term, high-intensity processing.
3. Grinding Processing Field
In grinding, the processing accuracy requirements are higher, usually at the sub-micron level. The main function of Spring collet is to provide precise positioning and stable support for the workpiece. Because the heat generated during the grinding process can easily deform the workpiece, the clamping force of Spring collet needs to be precisely controlled to ensure that the workpiece does not move and cannot be deformed due to excessive clamping force. At the same time, the surface quality of the workpiece in grinding processing requires near perfection, and Spring collet cannot cause any damage to the workpiece surface. In high-precision external and internal grinding, the high-precision concentricity and stable clamping performance of the Spring collet are crucial to ensuring the roundness and cylindricity of the workpiece. Compared with turning and milling, grinding has the most stringent requirements on the precision and stability of the Spring collet.
