| The Problem: |
Customer needed to rough and finish mill a bronze forging.
Roughing operation was .150" stock removal at 2" depth
of cut. Finishing operation was also 2" depth of cut. |

|
| The Solution: |
For roughing, we recommended a 1" diameter Cleveland
Twist Drill PM Plus Series 538 roughing end mill with
TiCN coating. Cutter was run at 1,500 SFPM (5,700 RPM, 180
IPM).
For finishing, we recommended a 3/4" diameter Cleveland
Twist Drill PM Plus Series 539 end mill also with TiCN coating.
Cutter was run at 1,500 SFPM (7,600 RPM, 274 IPM) taking .012"
per tooth. Customer reported zero deflection.
Customer could not say enough about the performance of the
two PM Plus tools. |
