Automating Post-Production to Scale-Up Additive Manufacturing
Unshackled by the limitations associated with traditional production processes, AM has made the leap from prototype to end part production and continues to open up exciting opportunities around localised production, digital inventories and on-demand manufacturing.
The Potential of Polymer 3D Printing - Exploring Advanced Manufacturing Processes and Bearing Design
3D printing has evolved significantly over recent years, with much of the research effort placed in the materials science field. This has enabled the development of a whole range of high-performance polymers with mechanical characteristics similar to those of metal.

T.J. Davies' Retention Knobs
Our retention knobs are manufactured above international standards or to machine builder specifications. Retention knobs are manufactured utilizing AMS-6274/AISI-8620 alloy steel drawn in the United States. Threads are single-pointed on our lathes while manufacturing all other retention knob features to ensure high concentricity. Our process ensures that our threads are balanced (lead in/lead out at 180 degrees.) Each retention knob is carburized (hardened) to 58-62HRC, and case depth is .020-.030. Core hardness 40HRC. Each retention knob is coated utilizing a hot black oxide coating to military specifications. Our retention knobs are 100% covered in black oxide to prevent rust. All retention knob surfaces (not just mating surfaces) have a precision finish of 32 RMA micro or better: ISO grade 6N. Each retention knob is magnetic particle tested and tested at 2.5 times the pulling force of the drawbar. Certifications are maintained for each step in the manufacturing process for traceability.
