Can I have prototypes or samples before placing the order? Sure, it can be made by soft tooling or hard tooling. What types of material can be machined for the sleeves and shafts? Aluminum, Copper Alloys (Bronze, Brass), Titanium, Nickel Alloys and all kind of Plastic material can be machined. Is it possible to know how are my products going on without visiting your company? We will offer a detailed production schedule and send weekly reports with digital pictures and videos which show the machining progress. What is a shaft used for? A shaft is a rotating machine element, usually circular in cross section, which is used to transmit power from one part to another, or from a machine which produces power to a machine which absorbs power. What manufacturing process are the shafts or sleeves to be used? Mostsly by using CNC turning can make a shaft or sleeve, sometimes CNC milling is also need to be used to make holes or irregular shapes processing. If the quantity is larger we will use swiss CNC turning process to make them.The samples delivery is about 7~15 days and the lead time for mass production is about 25-40 days.
