Simultaneous 5-Axis CNC Milling Solutions

Precision lapping and polishing services on all types of materials both hard and soft has been a specialty of Valley Design for over 50 years. We operate over 100 single and double-sided lapping and polishing machines ranging in size from 12”,18”,24” 28”, 32” 36”48”and 64” diameters producing parts from as small as .127mm (.005”) sq. to 450mm diameter and larger. Depending on the material, lapped finishes can range from 10-25u” Ra. Polished surfaces on ceramics can range from 0.3 -3u” Ra, and optical finishes on fused silica and glass can be as good as 3A Ra.

Our dicing services can cover all your needs from prototypes to production dicing services. With 15 K&S and DISCO dicing saws, we have one of the highest diamond dicing volume capacity in the industry. Silicon die from as small as .127mm square to Silicon stacks as high as 6.25mm can be diced, as well as a wide variety of hard materials including Fused Silica, Glass, Aluminum Nitride, Alumina ceramics, Sapphire, Silicon Carbide SiC, Silicon Silicon-Carbide (SiSiC) and many others.

Valley Design understands the importance of precision in microelectronic devices substrates. In our 50 years of experience, we’ve delivered a multitude of important semiconductor materials for electronics, and we’re pleased to include 450-mm silicon wafers. We offer 300mm and 450mm diameter wafer back grinding, lapping and polishing services on a wide variety of materials such as ceramics, glass, Fused Silica and Sapphire.

Valley Design provides lapping and polishing services of flat mechanical seals, pump parts, valve seats and discs. Valve components made from a large variety of materials include Hastelloy, Inconel, Monel, Stainless Steel, Carbon Steel, Copper, Nickel, Ceramics, Glass, Sapphire, Macor and many exotic materials. We have even polished large wind tunnels for NASA.

Over the years, Valley Design has served as a resource to its customers on Research & Development projects and provided technical support to the leading research institutions and labs worldwide. These include such distinguished technology centers as Lawrence Livermore National Lab, Los Almos National Lab, Lawrence Berkeley National Lab, Sandia National Lab, Army Research Lab, Massachusetts Institute of Technology (MIT), Rutherford Appleton Lab (UK) and Max Planck Institute (Germany).

Our capabilities in providing precision machining services make us a world-leading company in precision materials engineering and manufacturing. For nearly 50 years, our services have grown and evolved with the changing trends in precision material engineering and manufacturing. Our in-depth experience with components needed in the manufacturing of electro-static chucks (ESD) for the semiconductor industry, combined with our 3, 4 and 5 axis CNC machining services put Valley Design at the cutting edge of technology. We also offer CNC hole drilling, optical edge polishing services and small diameter core drilling.
