What is a screw machine?

A screw machine is an automatic lathe used for creating small to medium-sized circular and cylindrical components. This machine uses a rotating lathe to shave metal down to suit a particular design. A screw machine may use a single spindle or multiple spindles to shape a metal piece down to the desired size. These machines can work with great detail and complexity, and are capable of producing a large number of parts quickly.

What do screw machines make?

Despite the name, screw machines aren’t generally used to make screws. Screw machines commonly produce nozzles, fasteners, shafts, spacers, connectors and similar products. Screw machines can be used to produce many similar components with unique designs, including small, detailed parts, long, slender pieces, and everything in between.

What materials do screw machines work with?

Screw machines use metal bar stock and shave it down into the desired design. Our screw machines work with many different types of metal alloys, including mild carbon steel, aluminum and brass.

How close are screw machine tolerances?

Screw machines are preferred for many components because of their precision. Our screw machines are capable of producing detailed components with tolerances as close as +/- .002”.

What is a typical run for a screw machine?

Screw machines work quickly and can produce small runs around 1,000 pieces up to larger runs as many as 100,000 pieces or more.
