Screw Machine Products & Screw Machine Product Manufacturers

Although specialty screws and fasteners are a common product manufactured by screw machining, also known as Swiss screw machining, other types of turned parts have crucial applications as precision medical tools, automotive tools, laboratory tools, electronics components, appliance components, military parts and many others. Precision turning and machining processes are often required for the construction of such products. CNC turning and CNC Swiss machining are accomplished by CNC screw machines or CNC lathes and they produce quality CNC turned parts, which can also be described as precision turned parts. CNC machining and turning equipment may machine up to six parts simultaneously, and screw machining is considered one of the fastest and most cost-effective methods of small rotary part manufacturing. Different kinds of screw machines are capable of different processes, including knurling, thread rolling and many other processes. Once a screw machine tooling process has produced screw machining equipment, the possibilities for that equipment are extensive.

Screw machining offers design capabilities and structural benefits that cannot be cost-effectively reproduced with any other manufacturing method. Specialty fasteners, metal knobs, miniature medical instruments, bio implants, tire gauges, threaded rods, splines, spindles, fittings and a limitless variety of custom metal parts can be machined to precision tolerances by turning. Not only can metal parts be shaped by screw machining, but they may also be surfaced; turning can produce a smooth, near-polished finish or it can produce a knurled finish. Knurling is the process of creating a patterned texture on the surface of a metal to provide grip; common knurling applications include tool handles, metal flashlights, knurled nuts and knurled knobs. Knurled patterns are achieved with specialized CNC turning tools. Thread rolling and thread forming processes are employed in the formation of screw heads. Both processes involve pressing a shaped die against a work piece. Thread rolling and forming are cold forming processes, which requires a minimum threshold of ductility from the involved work pieces. In other words, metals formed by thread rolling and forming processes must be able to be formed by compressive force at low temperatures.

Both lathes and screw machines are used to produce screw machined parts, although screw machines are capable of carrying multiple spindles, unlike lathes, and are therefore more commonly used for mass production. Screw machines are also known as Swiss screw machines due to their invention in Switzerland in the 1800s. They may have more than eight spindles, which all operate simultaneously; round, square or hexagonal metal bar stock is attached to the spindles’ spring collets, which spin as multiple automated cutting, drilling, notching and knurling tools attached to the screw machine work the bar stock into parts by shaving away excess material, smoothing and drilling. The main drive shaft of a screw machine provides power to the machine bed’s lead work shaft and controls the two front cam shafts. The machine motor, located at the base of the machine, is the central power source for all operations and will vary in horsepower, depending on the size of the machine, speed and stock to be machined. Virtually any metal may be manufactured by screw machining; common screw machined materials include steel, stainless steel, brass and aluminum. Titanium is often used for sanitary and miniature medical tools.

CNC screw machining and CNC turning have greatly expanded on lathes’ manufacturing capabilities. Not only are screw machines capable of machining several parts simultaneously, but they also achieve high production rates, making it possible for manufacturers to make a large number of uniform precision machined parts with very little process time. Unlike manual lathes and non-CNC machines, multi-spindled CNC screw machines require a lengthy set-up process involving part design and system programming, including CAD design. For this reason, long runs are typically most cost effective, although no dies or hardware must be created custom for custom screw machine parts, making even short run screw machines a relatively cost effective means of precision production. Very few other metal forming and metal fabrication processes come close in precision to screw machining; some types of metal stamping can reach tolerances close to those of screw machined products, but for the extremely small, precision tools used in critical medical applications, screw machining is the only practical means of manufacturing.
