Chamfering Endmill AVIC
¢ Features • Cutting force is significantly reduced by the high rake design of the cutting edge. Burr-free machining suppresses the surface warping caused by machining. • For machining titanium alloys (KH26) and nickel-based heat- resistant alloys (ACF07C). Special materials are used for each to achieve stable and long tool life.
• Highly efficient machining with a 3-flute design
• Chamfering of front and back surfaces with only one tool
¢ Tool Shape
Front
Back
Chamfering of the front and back surfaces is possible with one tool
Secondary burr suppression Improved surface quality
3 flutes, high rake design, large rake angle
¢ Cutting Performance ¢ Cutting Force
The AVIC significantly reduces cutting force during chamfering.
