Surface Engineering is a trusted designer and manufacturer of high precision spindles, parts, and assemblies, specializing in turning and grinding. Located in an 18,000 square foot building in Sunnyvale, California, the heart of Silicon Valley, the facility was custom built for the purpose of creating extremely high precision components. We currently manufacture on a production basis several in-house aided designs of air bearing, ball bearing, and stage assemblies for the wafer and disc processing industries.

These applications require absolute state of the art 3D modeling, facilities, inspection, and assembly. Since 1976 Surface Engineering has provided first-rate customer support and on-time delivery of small lots or production quantities of our customers' most challenging designs, spanning uses from semiconductor manufacturing to medical.
Services
We have eight grinders capable of grinding ODs (outside diameters), two with the ability to grind ODs and IDs (internal diameters) concurrently.
All machines have in-process gauging.
This includes CNC-controlled Studer machines with the capability of grinding multiple diameters in one chucking, non-round and thread grinding capabilities as well as IDs.
A custom-made Blohm Planomat 412 is newly available to grind a field of 1200mm by 350mm to a flatness of 1 micron.
Resolution of 0.1 micron is possible.
With over 35 years of experience designing and building precision spindles and assemblies, the designers and staff at Surface Engineering are ready to apply their expertise to fulfill your requirements.
Surface Engineering products incorporate ball and air bearing structures with integral AC brushelss servo motors.
Typical speeds range from 0 to 20,000 RPM.
We can provide amplifier controls interfaces to the integral motor and encoder if required, or interface with your controls.
