· Climb milling is the recommended technique of milling.

· Workpiece rigidity is necessary for optimum cutting results.

· Correct coolant placement and pressure is essential for lubrication through the cut & to assure efficient chip evacuation and a longer tool life.

· Horsepower to cubic inch removal ratio should be checked for optimal performance.

· The minimum radial width of cut should not be less than the radius of the end mill.

· When slotting, the axial depth of cut should not exceed the diameter of the end mill.

· Feeds and speeds are recommendations and should be considered as starting points with possible variations to achieve optimum results.

· Workpiece rigidity should be checked to assure there is no vibration.

· Check the horsepower available to cubic inch of material removal.

· The proper coolant flow and placement will wash the chips out of the cut, thus eliminating the recutting of chips, and damage to the end mill.

· PROMAX Rougher-Finishers bridge the gap between full roughing and finishing.

· The PROMAX Rougher-Finisher can be used with any radial depth of cut.

· Surface footage generally can be increased with the rougher-finisher when light radial depths of cuts are made.

1. Manual override feed rate to 60% of recommendation.

2. Run end mill at 60% for 15 to 30 seconds into part.

3. Slowly increase feed rate to 100% of recommendation.
