Defense Industry CNC Precision Machining Services

Parkway-Kew Corporation supports demanding components that require CNC turning, CNC milling, large-diameter grinding, or hard-surfaced wear protection. Typical work includes wear parts, pulleys, sleeves, blocks, plungers, and other high-wear industrial components. Defense-related projects can benefit from the company’s experience with durable coatings, corrosion resistance, and parts designed for severe operating environments.

The company lists machining capabilities up to 72 inches in diameter for CNC milling, CNC turning, and manual turning. Large-diameter grinding capabilities extend up to 65 inches in diameter and 12 feet in length. These capacities make Parkway-Kew Corporation suitable for oversized, heavy-duty, or rebuildable components requiring accurate finishing and extended service life.

Yes. Parkway-Kew Corporation combines machining with wear-resistant coating application, including HVOF, plasma spray, thermal spray, fuse welding, and submerged arc welding. This allows parts to be fabricated, rebuilt, coated, and finished within an integrated workflow, helping improve wear resistance, corrosion resistance, and long-term durability for demanding applications.

CNC machining is often used when repeatability, geometry control, and efficient production are priorities. Manual turning remains valuable for specialized repairs, oversized components, rebuild work, and parts that require experienced operator judgment. Parkway-Kew Corporation offers both, allowing the team to match the machining method to the part’s size, condition, material, and performance requirements.

Yes. Parkway-Kew Corporation fabricates wear parts with coatings or without coatings, including solid tungsten carbide parts when coating is not required. One documented example involved redesigning a tool-steel pulley into a steel carrier with a solid tungsten carbide insert, dramatically improving wear life compared with the original tool-steel design.

Project requirements typically include drawings, dimensions, material specifications, target tolerances, operating conditions, wear issues, and any coating or surface finish expectations. For rebuild work, photos and information about the component’s failure mode are also useful. These details help Parkway-Kew Corporation recommend machining, grinding, or coating options that match the intended duty cycle.

Turnaround depends on part size, machining complexity, coating selection, grinding needs, and inspection requirements. Standard availability is Mondays to Fridays from 8:00 am to 5:00 pm. Because many projects involve specialized rebuilds or custom wear-resistant surfaces, the most accurate schedule is determined after reviewing drawings, part condition, and material requirements.

Parkway-Kew Corporation does not list specific defense certifications in the provided company information. However, the team can review project documentation requirements, part specifications, material needs, and process expectations before work begins. Customers with controlled drawings or special compliance needs should identify those requirements early so the correct workflow can be evaluated.
