DrillMeister – Gear housing – AH9130
IMPROVED TOOL LIFE
For bolt-through hole machining in a cast iron gearbox, conventional methods used a 5xD interchangeable head drill from another company with a long tool to avoid interference.However, there were issues with tool life.
To improve machining stability and extend tool life, we proposed combining the DrillMeister modular head with a Φ20 steel shank to enhance tool rigidity.
As a result, the number of holes machined increased from 1260 to 2115, achieving a 1.7-times longer tool life.
