Similar to lathes, they can produce parts at high speeds and may have multiple spindles – the most common configuration being a six-spindled machine. Every spindle contains the same material and turns its material at the same time as the other six spindles. Screw machine parts can be made from aluminum, plastic, wood, brass, steel, and other materials. Screw machine products are integral parts of the automotive, agricultural, medical, electronic, and recreational industries.
Screw machines increase production for screws and other hardware allowing manufacturers to produce products faster than they could make them by hand. Automatic screw machines are a type of lathe designed to produce screws and other small fasteners. Unlike lathes, the spindles on a screw machine are better suited for mass production of parts.
A wide variety of metals can be used in screw machines including steel, stainless steel, aluminum, titanium, and brass. Some of the first screw machines produced only screws, today the machines are used to make many different small metal parts. Parts can now be made faster and more efficiently saving manufacturers time and money which lowers the price for the end users.
