The FUJKE CBN tool has introduced a revolutionary "car-generation grinding" process that is both eco-friendly and efficient. But what exactly is car-generation grinding, and why is it gaining so much attention in the manufacturing industry?
Car-generation grinding refers to the use of CBN (Cubic Boron Nitride) or ceramic tools to machine hardened components. This advanced technique allows for the cutting of materials such as hardened steel, gray cast iron, ductile iron, powder metallurgy, and other specialized materials. Unlike traditional grinding, which often requires specific machines and tools, this method offers greater flexibility and cost-effectiveness.
One of the main advantages of using a car-generation grinding process is its lower cost. Compared to conventional grinding wheels, CBN tools are significantly cheaper—often only a quarter of the price. Additionally, they don’t require special fixtures or dedicated grinding machines. Instead, they can be used on existing CNC or NC turning centers, reducing the need for additional equipment.
Another key benefit is the high productivity it brings. CBN cutters operate at very high cutting speeds, which greatly improves efficiency and reduces machining time. This makes it an ideal choice for hard material processing.
FUJKE’s integrated polycrystalline (FBN) cutters are designed with precision in mind. They can achieve a machining accuracy of ±0.01mm and surface roughness as low as Ra 0.8–1.6μm. This level of precision not only enhances product quality but also eliminates the need for separate grinding operations. The entire finishing process can be completed in one setup, shortening the production cycle and saving energy. Plus, since dry cutting is possible, there's no need for coolant, making it a more environmentally friendly option.
With the recent drop in the cost of CBN cutting tools, the adoption of car-generation grinding has become more feasible. The cost savings aren’t just limited to the tools themselves; they also extend to the manufacturing process. CBN tools have a long service life and a low cost per cutting edge, making them the most economical solution for hard machining.
From an environmental perspective, car-generation grinding is far superior to traditional grinding. Conventional grinding produces a mixture of abrasive particles and coolant, which is difficult to recycle and harmful to the environment. In contrast, the waste generated by car-generation grinding can often be reused, making it a more sustainable option.
Factory space is another important consideration. Grinding wheels tend to be large and bulky, requiring significant storage space. CBN tools, on the other hand, are compact and can be used directly on existing machinery, eliminating the need for new equipment and saving valuable floor space.
The rapid growth of car-generation grinding is driven by continuous advancements in CBN tool technology. In the early 1990s, only a few CBN tools were suitable for this application. Today, the number of available options has increased tenfold. Cutting speeds have also improved dramatically—while the maximum cutting speed for cast iron was around 152m/min back then, it now reaches up to 1524m/min. For hardened steels, typical cutting speeds range from 90 to 150m/min, with feed rates between 0.05 and 0.2mm/rev and cutting depths of 0.1 to 0.5mm.
Moreover, the versatility of CBN tools has expanded. In the past, they couldn’t be used on brittle workpieces, but today, they can handle a wide range of materials with varying hardness levels. This makes car-generation grinding a highly adaptable and promising technology for modern manufacturing.
