The machining of materials with specific mechanical properties causes problems in terms of the required quality, economic efficiency, and overall effectiveness of the process. A number of works have been published which indicate that the subjects of interest are still important (Krolczyk et al. 2013). The machining of the aforementioned materials based on conventional methods does not always meet the requirements of eco-friendly technology nor the efficiency potential of the technological device and tool (Vasilko and Strojný 1967; Krolczyk et al. 2014). The abrasive waterjet (AWJ) represents a suitable technological method that has specific benefits resulting from the nature of the tool. Many scientific reports have been written about using the water jet and the AWJ for cutting (Summers 1972; Ciccu and Grosso 2014), drilling (Teale 1965), turning (Sitek 2009; Sitek 2005, 2011), and for the purposes of underground mining (Summers 1992; Sharma et al. 2011). The AWJ can be used for the creation of rotating symmetric parts from rocks by turning. The production of parts using standard methods is very complicated and even impossible for some rock materials due to their properties (Summers 1972; Agus et al. 1993; Aydin et al. 2013). The use of the AWJ is an option for how to eliminate problems related to the standard method of turning (Sitek et al. 2005). The first results were published by Dr. Hashish (1987) 28 years ago. Ansari and his colleagues (1992) undertook relatively extensive research into turning visualizations using a high-speed camera. Hlavac and Palicka (2006) applied this method for the turning of many materials used in industry. Axinte et al. (2009) applied this method for the turning of grinding wheels. Interesting results were obtained in glass turning (Zhong and Han 2002), alumina ceramic turning (Liu et al. 2014), and the turning of hard-strength materials (Sitek 2009). The application of this turning method enables the machine rotating of semifinished products of varying structures and shapes (Henning 1999).
