Case Study: Reaming Blind Bores in Steel


One of our customers was manufacturing electrical motion control components using a 4-spindle CNC Lathe in high volume. The parts were made of 1215 steel with an aluminum-bronze weld. This particular blind bore required a surface finish of 32 Ra microinch (.8 Ra).

When the customer contacted us, we recommended our Diatool 3252, standard monoblock reamer with Cermet blades and a unique geometry to achieve a very good surface finish without the need for a secondary operation. The reamer has (6) cutting blades and features coolant through the center of the tool.

The customer was very happy with the tool life and cycle time they achieved. They use two other reamer sizes also on high production jobs and have been a loyal customer since 2010.
