Company Profile


About

Incorporated in 1980, Specialty Components began producing precision products for the optics and aerospace industries. The production of metal optics frequently involved the use of air bearing machinery and measuring instruments. Air bearing consulting work evolved into the production of our standard series LRA linear air bearing pads. Their ease of integration and simple design quickly made them popular throughout the semiconductor industry. At the same time, we began producing our now popular UTT universal turntable cylindrical bearings for work-holding and roundness measurement. With nano-metric run-out (<50nm), smooth and frictionless motion, UTT bearings found uses in many grinding and diamond turning applications. Working with several universities worldwide providing them custom spherical air bearings led to the development of our standard SRA series. Over the past 10 years their popularity has grown considerably. In 2006, we produced our first 12,000 pound load capacity unit for satellite simulation with a 17 inch diameter sphere and +/- 45 degrees travel.

Manufacturing in our diamond point turning division has increased 800 percent since 2002. We have recently added to our CNC diamond turning equipment including a Moore diamond turning lathe with a B-axis. This lathe is capable of producing 20 inch diameter parts to nanometer form and finish. Also, we have two Nanoform 250 precision lathes. This machinery includes in-process optical measurement of surface form and finish on the machine to speed production.

To further meet our diamond turning needs, we have greatly expanded our ability to measure and characterize surface forms and finish with the recent acquisition of advanced optical measuring equipment. Our non-contact white-light scanning profilometer (Zygo NewView 5000) can resolve vertical surface roughness to 0.1 nanometers with step heights as high as 5mm without damage to the part. Our two laser interferometers (Zygo GPI XP Hr) measure form and flatness to lambda / 50 with partsup to 6 inch diameter in one measurement. Form and finish measurements can also be performed on our new Taylor-Hobson PGI 1240 surface profilometer with 0.8 nanometer resolution.  We also have purchased new in 2012 Zeiss’s most accurate production CMM for manufacture and qualification of our critical parts.
