Glass machining, Silicon machining and shaping

Precision Machining & CNC Machining of Hard Materials

Valley Design is a custom fabricator of precision machined parts from Glass, Pyrex, Quartz, Fused Silica (SiO2), Sapphire (A Plane, C Plane, R Plane), Aluminum Oxide (Alumina, Al203), Aluminum Nitride (AlN), Silicon Carbide (SiC), Boron Carbide, Steatite, Silicon, Zerodur, Macor, composites, and other ultra-hard materials. Valley also machines, laps, polishes and CNC machines a wide variety of metals including Stainless Steel, Aluminum, Titanium, Brass and Copper.

Small Diameter Optical Windows

Valley Design manufactures flat plano/plano optical and technical glass windows as small as 1mm in diameter which can be thinned and polished to as thin as 10-15 microns thick, optically polished with no edge drop off. Other geometries such as squares and rectangles with similar dimensions are also available.

Precision Machined Optical Blanks

Small optical blanks from Filter Glass, Fused Silica, Zerodur, Pyrex and all other optical glasses are precision fabricated by 4 & 5 Axis CNC machining, diamond core drilling, ultrasonic drilling, impact grinding, diamond sawing, dicing, grinding, lapping and polishing.

Machined Parts from Hard and Brittle Materials

Valley's over 45 years of experience enables us to produce precision diamond machined parts by CNC machining, grinding, dicing, drilling, lapping, ultrasonic shaping and polishing. Our expertise in hard and brittle materials is unique in the industry.

These hard and brittle materials can be machined into small heat sinks, washers, precision shims and spacers, cubes, wafers, seals, diode mounts and other intricate shapes. Valley Design is your resource for all your hard material machining requirements.
