Our grinding stones, sometimes also referred to as grinding wheels, are designed for dedicated automatic and semi-automatic plane-grinding machines. They produce absolutely flat sample surfaces and assure that all samples in a sample holder are ground to the same level in the shortest possible time and at a minimum cost.

Grinding Stone Types
The grinding stones are optimised for different types of materials and produced to suit different machines. A SiC based grinding wheel provides optimal grinding results for non-ferrous metals. The Al2O3-based grinding stone provides perfect results when grinding ferrous metals. Both types of grinding stones are available with or without a base plate depending on machine requirements. Our grinding stones are of the highest quality and therefore a cost-effective choice for the best automatic and semi-automatic plane-grinding machines without compromising the quality of the result.
A smart alternative to a grinding wheel are our diamond grinding discs, Aka-Piatto 80, 120 and 220. They also provide optimal flatness in a short time and do not require a dedicated plane grinding machine but can be used on all standard grinding/polishing machines.
Are the grinding stones available in different grit sizes?
As the grinding stones are designed for plane grinding and fast material removal, they are optimised for that and therefore only available in one grit size – #150.
How thin can a grinding stone get before it has to be replaced?
This depends on the type of grinding stone. If the grinding stone is mounted on a baseplate almost the total thickness can be used for grinding as the metal plate provides a very strong support. For stones that are entirely made of the abrasive/binder mix the amount to be used is much less. Therefore the bottom part under the flange is much thicker. But in both cases the usable height is normally defined by the machine that will stop the grinding process when the minimum height of the stone is reached.
When is a grinding stone the best choice for plane grinding?
As a grinding stone requires a dedicated plane grinding machine, which is a quite costly investment, a grinding stone makes sense when larger quantities of samples have to be ground on a daily basis. Also when larger amounts of material have to be removed, the speed of a grinding stone on a plane grinding machine outperforms other grinding options by far.
