Precision Metal Blanks for the Semiconductor Industry

We supply precision metal blanks for the semiconductor industry, serving the manufacturers of critical equipment and the machine shops that support them. Our process delivers machine-ready aluminum and stainless steel blanks that are ground, milled, and cut to tight tolerances, providing the dimensionally stable material required for components like base plates, vacuum chambers, and support structures. This eliminates the need for initial material preparation and allows our customers to move directly to their high-value finishing work.

Aluminum and Stainless Steel for Critical Equipment Components

The materials used in semiconductor equipment must offer stability and cleanliness. We primarily work with aluminum alloys like 6061-T651 and 7075-T651, which provide an excellent combination of strength, light weight, and machinability for structural components and vacuum chambers. For applications requiring higher corrosion resistance, particularly in cleanroom environments or where certain chemicals are present, we provide 304 and 316 stainless steel blanks.

Precision Processing for Semiconductor Components

Our value is in the processing that transforms a raw plate or bar into a machine-ready blank. We perform several key operations to ensure your material arrives with the flatness, parallelism, and dimensions your project requires.

Precision Grinding for Extreme Flatness

For components that require exceptional flatness, our precision grinding services deliver tight-tolerance surfaces. This process is essential for base plates, tooling, and fixtures where a uniform and flat foundation is critical for subsequent machining and assembly operations.

Saw and Waterjet Cutting for Near-Net Shapes

We produce blanks cut to near-net shape to reduce the amount of rough machining required at your facility. Our plate saws are capable of cutting thick blocks of aluminum and steel to precise dimensions. For more complex shapes or materials where maintaining the temper is critical, our waterjet cutting service produces blanks without creating a heat-affected zone.

Duplex Milling for Parallelism

Duplex milling creates two opposing surfaces on a block or plate that are flat and perfectly parallel to one another. This capability is vital for manufacturing components that must fit together with high precision, such as interlocking parts of a machine frame or fixtures that require parallel clamping surfaces.

Common Applications for Our Machine-Ready Blanks

Our precision blanks are the starting point for a wide range of components used in the construction and operation of semiconductor manufacturing equipment. Customers use our materials to produce items such as:

• Machinery base plates
• Vacuum chamber body and lid components
• Support frames and brackets
• Inspection equipment jigs and fixtures

Accelerate Your Production Timelines

By procuring a machine-ready blank from us, you can bypass the time-consuming initial stages of rough machining and material preparation. Starting with a part that is already flat, parallel, and cut to near-net shape frees up your internal machine time and skilled operator hours. This allows your team to focus on the final, high-value machining that defines your finished component, resulting in a compressed overall timeline from material procurement to final part delivery.

FAQs

What are the size limitations of your equipment?

Our grinding, milling, and cutting equipment can handle a wide range of material sizes, from small blocks to very large plates. To ensure we can accommodate your specific needs, please provide the overall dimensions of your required blank in your request.

Do your materials come with mill certifications?

Yes, all of our materials are sourced from reputable mills and can be supplied with full material certifications upon request. Please specify this requirement when you submit your project details for a quote.

Do you work with customer-supplied material?

Yes, in addition to supplying the material, we are able to process material that you provide to us. If you have existing stock or prefer to use your own material, contact us to discuss the specifics of your project and our processing capabilities for your components.

What flatness and parallelism tolerances can you typically hold?

Our standard tolerances for precision grinding and duplex milling are very tight, but final specifications depend on the material type, its thickness, and overall size. Please include your specific flatness and parallelism requirements in your request so we can confirm our capability for your project.
