Key Benefits At-a-Glance

NB’s experience in spindle shaft manufacturing and other precision machining dates back to 1939. In that time, we’ve developed a reputation for unsurpassed quality and innovation in everything we do. When you contact us for any spindle shaft engineering project, you are working with a company that’s dedicated to providing:

Flexible manufacturing options

including bearing case and spindle base design, complete unit engineering and overhauling of worn components

Precision machining capabilities

in our state-of-the-art, climate-controlled facilities designed to meet exceptionally high requirements for tolerance and overall quality control

Innovative surface treatments

including hard chroming and ceramic coatings for new components, as well as re-plating and grinding worn units to restore them

Our spindle manufacturing capabilities include BT, BBT, HSK inner tapers, gauge and bearing matching, thread grinding and more. We work with a wide range of standard materials, including high-carbon chromium bearing steel, Martensitic stainless steel, steel alloys and carbon steel for tools and machinery, aluminum chrome molybdenum steel and more.

Our facilities are equipped with CNC lathes, boring and milling machines, vertical machining centers, internal grinding machines and other machine tools. To discuss your specific requirements with one of our engineers, contact the NB office today by phone or email.

Total Manufacturing Solutions

NB is committed to providing total manufacturing solutions for clients in any industry. We’ll work with you every step of the way to deliver a product that meets your needs, offers excellent value for your budget and is turned around within a reasonable timeframe.

Upon receiving your drawings, we’ll review what’s required, order the necessary materials and develop a comprehensive plan for completing the project. From there, the spindle shaft production process involves multiple steps of turning, heat treatment, grinding and milling. It concludes with a final inspection to confirm we completed all work to the requested specifications.

Our internal quality management processes ensure we complete orders of any size on time, on budget and to the highest standards of accuracy possible. Highly skilled technicians use sophisticated 3D measuring tools and work in a climate-controlled environment to deliver the best possible results for our clients. We ship the final product with a complete inspection sheet confirming your order meets your specifications.
