Max spindle speeds possible Vertical chip ejection Longer tool life
Dramatic feed rate increase Quiet operation
WARNING: TOO LOW OF AN RPM COUPLED WITH TOO MUCH FEED MIGHT CAUSE THE TOOL TO SHATTER
FOR BEST RESULTS:
1. DIRECT MULTIPLE COOLANT NOZZLES AT THE END MILL TO ASSURE CONSTANT COOLING OF THE TOOL AND TO FLUSH CHIPS.
2. THESE TOOLS ARE SPECIALLY DESIGNED FOR HI-SPEED MILLING OF ALUMINUM.
3. THE FEEDS LISTED ARE STARTING POINTS. VARIATIONS OF THESE WILL DEPEND ON THE RADIAL & AXIAL DEPTH-OF-CUT & WORK PIECE
CONDITIONS
1. REDUCE FEED BY 50% ON LONG AND LONG REACH TOOLS OR WHEN AXIAL DEPTH OF CUT EXCEEDS 1.5XD
2. RADIAL RUNOUT OF TOOL TIP UNDER (.0005”) WHEN RUNNING TO ACHIEVE OPTIMUM FEEDS
3. CGS RECOMMENDS STARTING AT LOWER END OF SFM VALUES AND INCREASING AT CONTROLLED LEVELS TO ACHIEVE OPTIMUM FEEDS &
SURFACE FINISHES
Just as an “overnight success” is generally the result of years of effort,
a “breakthrough” in part machining productivity usually is the sum of a
number of carefully engineered individual improvements. Zaytran, Inc.
used several improvements to reduce machining time from more than
45 minutes to less than 20 for a 6061 aluminum component that
measured 6" x 5" x 2". Zaytran, located in Elyria, Ohio, is a leading
producer of precision grippers, actuators and locating pins focusing on
producing high-performance products. The component featured a 4.8"
deep cavity. The depth of the feature made it difficult to evacuate
chips, which resulted in surface finish problems. Machining time was
45 to 48 minutes.
Seeking to speed production, Jerry Williams, Zaytran process
engineer, consulted with CGS.
As a solution, CGS produced special versions of its Ferocious 2-flute, 55* high-helix, solid-carbide end mill by adding
through-coolant capability. The designs allowed coolant flow through the 3/4" dia. and 1" dia. tools with flute lengths up to
5", to effectively push chips out of the cavity. “There was no other way to get coolant down where the tool was actually
cutting,” said Steve Maxwell, Zaytran production team leader and programmer.
Zaytran was able to square the parts using just the CGS end mills, while other suppliers’ end mills, with profiling lengths of
3" to 4", were unsuccessful, thus causing Zaytran to have to apply face mills on two sides. Face milling proved
unnecessary when applying CGS end mills in shrink-fit holders. “We could do profile milling, 3-1/2" or 4" deep, and
maintain 0.001" or 0.0015" taper over the whole length of the part, eliminating the need for the face mills,” Maxwell said.
A large contributor to the decrease in machining time was the end mills’ capability to run at high speeds and feeds. The
micro grain-carbide tools feature a circular land that facilitates maximum feed rates and cutting speeds, and the tool
geometry is engineered to produce efficient sharing action and vertical chip ejection. Williams said the shop typically runs
the end mills at feeds of 100 ipm or faster, in contrast to the 40-to-50 ipm feeds employed with previously used end mills.
