For grinding wheels for titanium, armored steel, Inconel ®, tool steel, high-nickel alloys and other hard-to-grind metals, get fantastic results with a Tiger Ceramic grinding wheel. These tools take on any metal types and deliver a superior combination of cut rate and wheel life.
Considering the physical mechanisms involved in the grinding process, the model provides more in-depth knowledge about the grinding forces which can be used for finding the optimum conditions. This model is able to explain some inherent characteristics of grinding forces such as the high ratio of normal to tangential force and high specific grinding energy in low feed rates and depth of cuts.

The new profile grinding spindle (Figure 3) is used when grinding gears with space or feature limitations such as small diameter wheels are called for—as small as 60 mm, in fact. This unit is simply mounted to the standard grinding spindle in place of the larger wheel that is used for the continuous generating process.
With the in-feed method, the regulating wheel spins the part at one speed while pushing it towards the grinding wheel, which is spinning at a faster speed. The greater the difference in speeds, the faster the removal rate. 4. The choice of grinding …
Complex grinding requires innovative solutions. Armed with additive manufacturing technology, 3M has developed a groundbreaking new solution in precision internal diameter grinding. New 3M™ Precision Structured Vitrified CBN Grinding Wheels are 3D printed, layer by layer, to help you reach higher dimensions of performance in cylindrical grinding.
When you're grinding hardened steel and superalloys, you need a grinding wheel with a hard mineral and a reliable bond. 3M Cubic Boron Nitride (CBN) grinding wheels with vitrified bonds stand up to the most demanding precision grinding applications. ... Our partially crystallized glass bonds have higher inherent strength than bonds of ...

If you want a good grind, put a ring on it! This adapter provides no inherent means for balancing the wheel. Some much larger wheel adapters have balancers built in. There is a pervasive falsehood in the grinding world that "small wheels don't need to be balanced", and that "you can true the wheel to remove the effects of imbalance."
