Ordinary abrasive grinding wheels such as white aluminum oxide, silicon carbide, and SG have always been evergreen in the field of gear processing. However, in recent years, super-hard abrasive grinding wheels have also emerged in this field, and have also performed well in some high-precision and high-shape retention fields. This article briefly discusses the advantages and disadvantages of super-hard gear grinding wheels and ordinary gear grinding wheels.
Advantages:
Excellent hardness and wear resistance
Vitrified CBN gear grinding wheels have higher hardness and wear resistance than traditional grinding wheels. CBN (cubic boron nitride) is a very hard material, harder than traditional corundum (aluminum oxide) abrasives, so it is more suitable for high-speed and efficient grinding processes.
High grinding efficiency
Due to its hardness and wear resistance, vitrified CBN gear grinding wheels can maintain their grinding performance for a longer time, are not prone to wear and deformation, and can complete the same amount of work in a shorter time.
Improve processing quality
The use of vitrified CBN grinding wheels can improve the surface accuracy and finish of the workpiece, and reduce the surface damage and deformation of the workpiece caused by grinding.
Cost saving
Although the cost of vitrified CBN grinding wheels themselves is relatively high, due to their strong wear resistance, they require less replacement and dressing, which can save overall grinding costs in long-term use.
Disadvantages:
High cost
Compared with traditional ordinary grinding wheels, vitrified CBN gear grinding wheels are more expensive, which is a limiting factor for their popularity and widespread use.
High processing technology requirements
Using vitrified CBN grinding wheels requires a higher level of processing technology and professional operating skills to ensure grinding results and workpiece quality.
Not suitable for all materials
Although vitrified CBN gear grinding wheels perform well in most metal processing, they may not be suitable for certain materials or composite materials or require specific design and selection.
In summary, vitrified CBN grinding wheels are suitable for applications that require high efficiency, high precision and long life grinding, but their high cost and professional operating requirements limit their widespread use in some applications.
In traditional large gear grinding, due to the high unit price of vitrified CBN grinding wheels, in this field, traditional gear grinding wheels are indeed more in line with the company's equipment, process, and tool cost control. However, in small-size, high-precision gear grinding, ceramic CBN gear grinding wheels have incomparable advantages over traditional gear grinding wheels. Enterprises can flexibly choose according to their own needs.
