H P Machine & Engineering Inc

Applied Fusion is a provider of electron beam welding. Electron beam welding is a process that joins metals with minimal distortion. The process enables welding to take place in close proximity to heat-sensitive components and hermetically sealed welding of evacuated enclosures while a vacuum is retained inside of the component. The company welds a variety of standard metals, as well as titanium, tantalum, niobium and molybdenum. Its facilities house several computer-numerically controlled and programmable electron beam welders. The welders feature a chamber size that is 3 feet by 7 feet by 8 feet. The rotary-tilt tables have a capacity of 7,500 pounds. Applied Fusion is located in San Leandro, Calif.

Surface Engineering brings to the market over 30 years of custom design, extremely close tolerance grinding and assembly experience on precision rotary spindles. Our products incorporate ball and/or air bearing structures with DC and AC brushless servo motors. The typical speeds range from 10 to 10, 000 RPM with speeds of over 30, 000 RPM possible. Surface Engineering can provide DSP based motor control & drive systems for speed control of +/- 1 RPM at 5, 000 RPM. State of the art design, manufacturing and inspection capabilities allow spindle errors of 0.5 microns and asynchronous errors of 0.25 microns.
