The CNC turning and milling method is one of the most popular ways of producing precise threads. In this method, processing is carried out on a CNC lathe, which is capable of performing very accurate and repeatable turning operations using shaped tools such as inserts or cutters. Grinding, on the other hand, is a machining process that allows for a very smooth thread surface. The Reishauer NRK machine is one of the most advanced machines for grinding threads, which allows for very accurate and repeatable results. The grinding tool used is a diamond-shaped ceramic grinding wheel.
