Cutting knives are used in a large variety of industrial sectors. In the woodworking industry, planing knives of various lengths are required. Circular knives are used in other industrial sectors, like the paper and metalworking industries. There are also machine knives and profile knives. After a certain amount of time, tools need to be ground. Some companies can provide this as a special service.

However, if one requires a high number of knives to be ground, it is useful to buy a machine and stay independent from the grinding shops. Knife grinding machines are machine tools that sharpen knives using grinding wheels. It is important to make sure that the knives do not wear out by the grinding process, and thereby soften the tool steel. Using these machines to grind knives does require a certain amount of experience.
Particularly long planing knives need to be clamped in along their whole length and can be moved along the grinding wheel using a mobile carriage. This prevents the planing knives to be worn and ensures that the cut surfaces maintain their sharpness. This guarantees the tools create a clean cut in the processed material. A further use of this machine is to manufacture knives and scissors. After these products are manufactured, they are finished by being ground.
Basically, all knife grinding machines contain a clamp to hold in the knife. Furthermore, a grinding head is available, which can house grinding wheels of various grain sizes and diameters. The grinding wheels are operated by an electric motor and have a high rotation speed. A large part of the machine is equipped with a cooling device. This cooling device prevents the cutters from overheating during the grinding process.
