Shaft Manufacturing Process and Quality Standards
The Shaft Manufacturing process starts with understanding the application, operating conditions, cause of failure of previous shafts, and project requirements including third-party approvals and testing. Depending on failure analysis results, the engineering team may suggest a design modification or other components to be manufactured.
The Engineering team verifies and records the dimensions of the shaft, design and create prints if not available from OEM. Additional strength calculations, bending, and torsional stress calculations are also considered to enhance the performance of the new shaft.
Manufacturing the shaft then involves CNC turning. A bar of solid material like steel is attached to chucks and cut with specialized tools through a subtractive process. Subtractive processes such as cutting and grinding shape the shaft to the proper dimensions and tolerances. Machining processes like boring and drilling create grooves where gears attach to the shaft. Specialized shafts may use different machining processes and require a specific material. Metallurgical analysis can be used to ensure the selected material fits the application.
The material used needs to have a high tensile and endurance strength to withstand static and dynamic loads. If gears are attached to the shaft, the gear is usually made from an extremely durable material, such as carbon steel. These can be further hardened by heat treatment. Depending on the application, some shafts would require additional protective coating such as fiberglass/ epoxy polymer.
Quality manufactured shaft can extend the life and reliability of many critical components used in various industries with demanding operating conditions such as in marine, hydropower, wind, pulp & paper, oil & gas, and manufacturing.
Our shaft manufacturing facility is well equipped with CNC lathe with 78″ centers, engine lathes with 78” swing X 482” centers, vertical boring mill with 103″ vertical, horizontal boring with 60″ x 120″ table capacity.
Most importantly, Western Machine Works has an experienced team of engineers and technicians who can tackle any challenging project. The shaft manufacturing process at Western Machine starts and ends with an engineering-focused approach, valuing quality control with comprehensive initial and final dimensional checks.
More about Shaft Manufacturing
In mechanical terms, a shaft is a rotating component that transfers rotational power from one part to another. Shafts are almost always cylindrical, and often have a toothed wheel or gear that connects to another component to transfer energy to the absorbing component.
Shafts play an intrinsic role in the mechanics of many industries: energy, marine, aerospace, automotive, oil & gas, mining, manufacturing, agriculture, and paper milling.
Engineers can connect shafts and gears of different sizes to create more torque, mechanical energy, and power within equipment.
Shaft manufacturing involves innovative techniques and technology to make the shafts more productive and meet tighter tolerances.

Shaft Manufacturing Projects
This 850 HP rotor used for a chemical compressor was failing due to a bearing fit damage to the shaft. Western Machine Works inspected the part and determined that the damage was not repairable. A new shaft was reverse engineered, manufactured, and installed within the customer’s production schedule.
Western Machine Works reverse engineered and manufactured a new shaft for a motor armature. The old shaft was severely damaged and repairing it was not a viable option. The armature bore was precision machined to 100% concentricity and the new shaft was installed with the required interference fit.
The plate roller shaft broke off of a drive roll with the bearing housing and bearings still installed. The engineering team evaluated the loading parameters and operational stress analysis and developed an interference shaft fit design. A new shaft was manufactured using a 4340 steel material.
Western Machine Works provided a comprehensive shaft manufacturing solution for this shaft that broke off with both bearing housing and bearings still installed. Our engineering team proposed an interference joint design and manufactured a new shaft that will be as strong as the original and will be optimized for long-term runnabilty. Manufacturing new shafts with an engineering-focused approach sets our process apart and ensure reliability from start to completion of the project.
