A complete guide to grinding wheel technology

The selection of a grinding wheel’s bond strength is a critical aspect of grinding operations. It must be based on grinding theory while considering multiple factors, including the physical properties of the workpiece, the relative speed of the grinding wheel and workpiece, the size of the contact area, the grinding method, and the stability of the mechanical equipment.
Soft workpieces are best suited for hard grinding wheels, while hard workpieces require soft grinding wheels. For high-speed operations, softer bond strengths are preferable, whereas low-speed operations favor harder bond strengths. Workpieces with large contact areas require soft grinding wheels, while those with small contact areas are better suited to hard grinding wheels. Manual grinding and equipment with high vibration call for hard grinding wheels, while stable mechanical grinding is better suited to soft grinding wheels.
Selecting the appropriate bond strength not only enhances grinding efficiency and processing quality but also extends the life of the grinding wheel and reduces costs, providing a foundation for efficient and cost-effective machining.

The grinding wheel is an indispensable tool in grinding processes, and its performance directly impacts machining efficiency and the surface quality of workpieces. During grinding, the cutting edges of a grinding wheel exhibit an irregular distribution at the microscopic level, undergoing complex changes such as wear, dislodgment, and self-sharpening under high-temperature and high-pressure conditions. These

This chapter discusses key issues in grinding processing, including machining surface accuracy, smoothness, and surface stability. Due to thermal load and mechanical stress, problems such as deterioration, residual stress, and poor surface roughness often occur, which in turn affect the performance and lifespan of the workpiece. Corresponding solutions are proposed to improve processing quality.

Grinding processing is a precision surface treatment technology, where controlling the surface roughness of the workpiece is crucial for quality. Surface roughness affects appearance and functionality, such as wear-resistance. The article discusses the definition of surface roughness, influencing factors, and improvement methods, emphasizing the importance of selecting suitable grinding wheels and controlling various parameters to enhance processing quality.

Grinding heat is an important phenomenon caused by high-speed friction between the abrasive grain and the workpiece during the grinding process, which will affect the workpiece and the grinding wheel. Controlling the generation and transfer of grinding heat, utilizing the appropriate coolant and adjusting process parameters can help to improve the surface quality and process stability of the workpiece.
