Ball end mills are used for drilling shallow holes, slotting a channel where a flat bottom is not required or most commonly used to produce multi-dimensional contours in molds or dies. The design of ball end mills forms a hemispherical cutting action identical to the diameter of the tool. Because of the shapes required in these products it's common that multi axis machining
Drilling speeds and feeds are based on jobber length drills. For deep hole drilling reduce speeds by 10% for 3xDiameter, 20% for 4xDiameter, 30% for 5xDiameter and 40% for over 6xDiameter. Important Disclaimer: The Accupro speed and feed rates are suggested by .

Like anything else having the right Feeds and Speeds is very important when Thread Milling. A Threadmill can be small, delicate, and expensive, so it's no fun to break one. The good news is our G-Wizard Feeds and Speeds Calculator does Threadmill Feeds and Speeds.
Milling Speeds and Feeds Charts The most important aspect of milling with carbide end mills is to run the tool at the proper rpm and feed rate. We have broken these recommendations down into material categories so you can make better decisions with how to productively run your end mills.
Acrylic works very well with all sizes of end mills; however, the tool should be very sharp, preferably one reserved for use only with plastics. During cutting, you should pause the job every so often and clear chips from deeper slots and cutouts to avoid the material binding onto the tool.
Mar 10, 2009 · A little help with speeds and feeds for ball endmills. What do some of you recommend for speeds and feeds for a 1/2 diameter solid carbide 2 flute ball end mill roughing 1018 cold rolled steel. DOC, RPM, Feed rate? What is a good rule of thumb for this.
The phrase "speeds and feeds" (or "feeds and speeds") refers to two separate velocities in machine tool practice: cutting speed and feed rate. They are often considered as a pair because of their combined effect on the cutting process.
