With the investment of a 3D printer, we can now 3D print certain parts for our machine tools in house. This initiative originated from a Lean Six Sigma cost-savings proposal developed by our Chief Engineer, Syed M. Hasan, focused on identifying machine components that could be produced more efficiently through 3D printing.

After the analysis of the idea was completed, it was determined that the cost savings and reduced lead times justified the investment. The idea was then put into motion with support from the city of Rockford through a grant program. We are now 3D printing 90-100 different types of parts!

Happy new machine day! We just finished installing two new Bridgeport XR 1000 mills to replace our older Haas mills. Matt, our shop foreman, is running them off today. These machines have 12,000 RPM Big Plus 40-taper spindles so we'll be making a lot more chips a lot faster!
