Tool grinding machines are nowadays operated fully automatically. They are utilized, among others, for sharpening drill bits, knife blades, milling cutters, and lathe tools etc.
The highest form of automation is the grinding machine with integrated measurement control, where measurements are performed at regular intervals and the grinding process is subsequently adjusted accordingly. The measurements can be scanned or selectively taken. In addition, the abrasive tool is brushed and rotated during the grinding operations.
Surface grinders are used for grinding flat surfaces. Different spindle variants provide these machines with their versatility.
When used in combination with professional CNC controls many diverse high-precision grinding tasks can be realized.
Milling machines produce the desired shapes of the work pieces by removing material from them with the help of its rotating cutting tools. Because the milling machines have at least three feed directions, then complex spatial bodies can be prepared. Thus complex parts such as engine blocks or gear wheels are produced with milling machines, but simple jobs such as drilling or reaming precise holes are also possible. In modern machines the axes of motion are often implemented with quite different relationships to each other. Additionally, rotational or moveable tool pieces or work piece holders are also now common.
