DrillMeister DMP -Automotive drivetrain component-
IMPROVED TOOL LIFE
For drilling of an automotive drivetrain component, an DrillMeister DMP head was proposed. Under the same cutting conditions as the existing tool, the number of holes per cutting edge increased from 1,700 to 3,000 while maintaining equivalent surface quality, resulting in a 76% improvement in tool life.
