Metal Machining

Precision Metal Machining to Meet Exact Customer Specifications

With over 200 on-site machining centers, MetalTek specializes in rough and finish machining to meet demanding customer specifications and minimize lead times. We machine components up to 200 in. (5 000 mm) outer diameter (O.D.) and up to 200,000 pounds (90 718 kg). Sandusky International can bore centrifugal castings up to 50 ft. (15 m) in length, a capability matched by few machine shops in the world.

MetalTek’s machining expertise extends beyond standard dimensions to complex shapes and custom geometries requiring specialized tools and fixtures. Whether machining high-carbon alloys known for their hardness or ensuring precise tolerances on intricate components, we deliver superior results. MetalTek also prioritizes sustainability by reclaiming machine chips to reduce both material costs and waste.

MetalTek's use of state-of-the-art computer numerical control (CNC) technology offers:

Unmatched precision to achieve exact tolerances and repeatability
High-speed production on-site to limit lead times
Scalability to adapt to a range of production needs
Versatile material compatibility to machine a wide range of alloys and metals

If we somehow cannot meet a customer’s machining specifications, we rely on one of our trusted outside metal machining partners. Contact us to learn more about our machining capabilities and how they can contribute to the success of your project.

Meeting Exact Customer Specifications with Advanced Metal Machining

Metal machining is the precision art of removing unwanted metal from a casting or workpiece to achieve exact dimensions and superior surface finishes. With over 200 metal machining centers across our network, we are equipped to handle the most demanding customer requirements.

Unparalleled Large Part Machining Capabilities

Our capabilities extend to impressive dimensions, including outer diameters (O.D.) up to 200” (5000 mm) and weights up to 200,000 pounds (90 718 kg). A key differentiator is our ability to bore centrifugal castings up to 50’ (15 m) in length – a capability matched by only a handful of metal machine shops worldwide. Whether you require custom-machined parts for aerospace, defense, energy, or other critical industries, our network offers tailored solutions.

The MetalTek Metal Machining Process: Precision and Efficiency

Our process is meticulously focused on your specific project needs. We handle a wide range of dimensions, from standard configurations to unusual shapes like balls and spherical components, often requiring specialized tools and fixtures. We also prioritize sustainability by reclaiming machine chips, which allows us to recycle materials and offer competitive metal machining costs for the parts we cast. If a customer's unique machining specifications fall outside our direct capabilities, we leverage our trusted network of outside metal machining partners to ensure your project's success. Our team collaborates closely with every customer, ensuring efficient project management, cost-effectiveness, and adherence to the highest standards.
