Greenleaf End Mills Optimize Machining Stability

Greenleaf Corp.’s 
Capstone-360 high-performance end mills feature a ceramic tip combined with a carbide shank. Capstone-360 provides the speed and efficiency of solid ceramic end mills with the additional strength and stability provided by the carbide shank, offering optimized tool life.

Designed for high-performance slotting, pocketing and face milling applications, Capstone-360 is well suited for machining heat-resistant super alloys (HRSAs), cast iron and hardened steel materials for the aerospace, oil and gas, power generation and medical industries.

Features of Capstone-360 include:

• Optimized value and high performance: Delivers an optimal balance of productivity and tool life.
• Lower heat generation: The specialized combination of geometry and chemistry optimized for Ni-base HRSAs results in lower cutting forces and less heat generation even at speeds as high as 2,600 sfm (800 m/min), improving dimensional tolerances and tool retention, and reducing spindle wear.
• Necked shank for additional clearance: All tools feature a necked shank that enables access to cavities and facilitates programming in shoulder milling while maintaining rigidity.
• Versatility: Capstone-360 performs well at a wide range of cutting speeds in HRSAs, and offers similar cycle time and cost reduction benefits in most face-milling applications in hardened steel and cast iron.

“By combining advanced materials with cutting-edge design, we have developed an end mill line that enhances productivity, extends tool life and provides greater value across a wide range of applications,” says Bernie McConnell, executive vice president – commercial at Greenleaf Corp. “Capstone-360 represents a significant step forward, providing our customers with a powerful solution to maximize efficiency and extend tool life in demanding applications.”
