Custom CNC Milled Metal Castings — Manufacturing Services

Custom CNC milled metal castings are cast metal parts machined after casting to achieve precise dimensions, finishes, bores, grooves, and mounting features. CNC milling removes material accurately and repeatably, making the casting ready for assembly or further finishing. Parkway-Kew Corporation can also pair machining with turning, grinding, and coatings when the application requires better wear or corrosion resistance.

Tolerances are reviewed against the part geometry, casting condition, material, machining sequence, and final application. Parkway-Kew Corporation evaluates drawings and wear requirements before recommending the best path, whether that involves CNC milling, CNC turning, manual turning, grinding, or coating. This helps ensure the finished component supports the intended fit, surface finish, and operating life.

Yes. Parkway-Kew Corporation has machining capabilities for parts up to 72 inches in diameter, along with large diameter grinding up to 65 inches in diameter and 12 feet in length. These capabilities are valuable for industrial castings, rebuilt wear parts, capstans, pulleys, sleeves, and other components that are too large for many standard machine shops.

Yes. CNC milling can be combined with wear-resistant coating options such as HVOF, plasma spray, thermal spray, fuse welding, and other hard surfacing methods. The engineering team recommends alloys and surfacing technologies based on wear, corrosion, surface finish, and operating conditions. This is especially useful for components exposed to heavy friction, heat, or abrasive materials.

In many cases, worn components can be rebuilt rather than replaced. Parkway-Kew Corporation has deep experience restoring industrial parts with hardfacing, coatings, grinding, and machining. Rebuilding can reduce downtime, preserve usable base material, and extend service life. For some applications, specialized processes can repair only worn areas instead of removing unnecessary good material.

These services support heavy industrial customers such as wire mills, oil and gas operations, shipping terminals, heavy equipment manufacturers, earth-moving equipment companies, and container loading or unloading operations. The common need is durable, accurately machined components that can resist wear, corrosion, friction, and repeated production stress while helping reduce frequent changeouts.

Lead time is established after reviewing the part size, material, drawing requirements, coating needs, inspection steps, and current production schedule. Parkway-Kew Corporation operates Mondays through Fridays from 8:00 am to 5:00 pm. Providing drawings, photos, wear patterns, quantity, and operating conditions early helps the team evaluate scope and plan the most efficient manufacturing sequence.

Helpful project information includes part drawings, dimensions, material type, quantity, current wear issue, target surface finish, coating requirements, operating environment, and whether the part is new or being rebuilt. If drawings are unavailable, photos and detailed measurements are still useful. Parkway-Kew Corporation can then recommend milling, turning, grinding, coating, or fabrication options.
