Aluminum and its alloys, except iron alloys, found nowadays the broadest application in any type of design structures. Modern technologies, as well as tendencies aimed at the broadest possible use of light alloys - Al-Si mainly - call for more and more rigorous requirements. These requirements concern not only mechanical properties, but also technological features like: castability, capability to be fed of the casting, tightness, machinability. Automation of production, being result of mass series production, effects in increased requirements concerning properties of starting material, inclusive of machinability mainly. The paper presents a preliminary results of AK9 alloy machinability, subjected to typical treatments of refining and modification. Measurement of machnability of investigated alloy was performed with use of reboring method, with fiat drill and constant feed force. It has enabled to determine a correlation between implemented enrichment treatments and machinability of investigated alloy. Further investigations shall be connected with determination of machinability of heat treated alloy and determination of optimal parameters of enrichment treatments in aspect of machining operations of casting made from AK9 alloy.
