Advantage of grinding process. There are following advantage of grinding process as mentioned here. Investment is less. Working principle and operation is simple. It does not require additional skills. Surface finishing will be approximate 10 times better as compared to milling and turning process of machining.
CBN grains do not chemically react with steels and retain their strength above 10000C.Grinding with CBN wheels also improves the fatigue strength and extends the useful life of the cutting tool.
CBN is well-known throughout the industry as the best suitable grain for grinding hardened alloys since it does not generate a high temperature. This stability is due to the fact that CBN has a good conductivity for temperature; therefore the heat generated disperses quickly, helped by the shape of the metal body of the wheel.
The desire to grind faster is a reason to consider CBN. Since it has a higher hardness and can stay sharp longer than Al 2 O 3 or ceramic grains, it can be pushed harder and cut quicker. CBN grain hardness also helps maintain cutting ability for longer periods without redressing. The reduced frequency of dressing eliminates downtime. 2.
CBN Grinding Wheels. We have been using CBN grinding wheels for sharpening our turning tools for years, and have found them to be a real asset. The wheels are factory balanced, which makes our grinders run very smooth. The grinding wheels have a full 1 1/2" face to use, and they don't need any dressing - therefore you don't have the mess of truing wheels and won't …
CBN is used mainly for grinding high quality tool steels. Because of its chemical nature, CBN has no affinity for low carbon steels, being widely employed for grinding high-speed steels. CBN has an excellent thermal stability; oxidation starts above 1000 °C (1800 °F) and becomes complete around 1500 °C (2700 °F).
They will not react when lapping ferrous metals. Nor are they prone to oxidation when grinding steel alloys. These combined properties make CBN grains the abrasive of choice for high-performance grinding wheels tasked with cutting or roughing cast iron, nickel-based alloys, and a wide range of steel grades. Types of CBN Grinding Wheels
When using cBN grinding wheels, less time is spent dressing the wheel, allowing increased machine up-time for grinding gears. Gear quality is improved by the inher-ent benefits of grinding with cBN add-ing to the compressive residual stress of the gear tooth. Additionally, cBN helps to transmit heat much the way copper transmits electricity, by ...
