How We Make Micro Precision Screws and Screw Machine Parts

We use a variety of machines and manufacturing techniques to produce ultra precision screws for our OEM customers, including:

  • Single spindle Tornos / Tornos Bechlers with up to 6 attachments (including Polygon) for screw sizes .010 inch diameter to 1.0 inch in diameter. In this approach, cam operation assures excellent repeatability of high precision screw part dimensions, while the single spindle system assures maximum accuracy for parts.
  • Tornos Deco 2000 is used mainly for mass-produced parts, including Swiss precision screw machine parts, providing exceptional operating flexibility and reliability. Diameters range from .10 to 1 inch.
  • Transfer Machines: Our transfer machines include Hydromat and custom machines. These are employed for complicated mass-produced screws and parts like housings.
  • CNC machines: Most useful in shorter runs, our computer numerical control (CNC) machines help automate control of machine tools through software. These machines enable precision screw creation up to 1.6 inch diameters.
  • WAHLI gear cutting machines, that provide extraordinary precision and accuracy for screw manufacturing.
  • Escomatic machines, which we employ for simple, mass-produced precision screw products.
