Precision turning of an industrial metal component

Our Diamond Turning Services — Precision Machining Services

Precision machining, grinding, fabrication, and coating support for durable industrial wear components.

CNC Turning

CNC turning supports accurate machining of industrial wear parts, coated components, and solid tungsten carbide parts, with capabilities for workpieces up to 72 inches in diameter.

Manual Turning

Manual turning provides flexible machining support for custom components, repairs, and specialized part geometries that benefit from experienced machinist control and practical adjustment.

CNC Milling

CNC milling complements turning and coating work, allowing wear parts to be fabricated, modified, or finished with precision for demanding industrial applications.

Large Grinding

Large diameter grinding handles components up to 65 inches in diameter and 12 feet in length, supporting accurate finishing for substantial industrial parts.

Carbide Parts

Solid tungsten carbide parts can be fabricated without coatings, helping improve wear life in applications where traditional tool steel components fail too quickly.

Wear Coatings

Wear-resistant coating application can be paired with machining to improve corrosion resistance, reduce wear, and extend the operating life of critical components.

Portrait of Eugene Walter Klein, Founder of Parkway-Kew Corporation

Eugene Walter Klein

Founder

Eugene Walter Klein is the visionary founder of Parkway-Kew Corporation, establishing the company in 1952 after identifying an innovative solution to a pressing industrial challenge. As a welding supply salesman, Eugene was approached by a valued customer seeking help repairing worn machine parts and improving their wear resistance. Drawing on his expertise, he recommended a specialized hardfacing wear-resistant weld alloy, proved the concept by welding the first test piece in his own garage, and secured the company's landmark first order to rebuild 100 wire drawing blocks. His entrepreneurial spirit and deep technical knowledge laid the foundation for what would become the world leader in hardsurfaced wire drawing blocks and capstans, a legacy that has endured for over 70 years.
