We like Constant Torque Because of the unique geometry our tools perform best under constant torque Take a look at the torque curve for your CNC machine If you have a 10 000 RPM spindle motor and the torque drops from it's constant peak at 8200 RPM then 8200 RPM would be the maximum RPM

Ball milling is a grinding method that grinds nanotubes into extremely fine powders During the ball milling process the collision between the tiny rigid balls in a concealed container will generate localized high pressure Usually ceramic flint pebbles and stainless steel are used 25 In order to further improve the quality of dispersion and

Apr 02 2011I can help in inches rpm = cutting speed x 4 divided by cutter dia cutting speeds roughly alloy steel = 50 feet per minute cast iron 70 mild steel 80 to 100 and brass and aluminum 200 these are for hss tools If you talk limey its aluminium In the lathe dia is the diameter of the work you are turning Of course if you are drilling a 1//4

The feed (milling machine feed) can be defined as the distance in inches per minute that the work moves into the cutter On the milling machines we have here at LBCC the feed is independent of the spindle speed This is a good arrangement and it permits faster feeds for larger slowly rotating cutters The feed rate used on a milling machine

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 Cutting speed (SFM) SFM - Also called surface speed or simply speed is the speed difference ( relative

Jun 07 2006If I was starting from scratch on this setup I would go for 300 sfm for carbide in mild steel and calculate the best RPM as: RPM = 4 x 300 sfm/ 125 = 9600 RPM However you can't spin that fast so we set the RPM at your max 4200 I use the following formulas and guides to calculate the chip load per tooth and thus feed rate

Basic Math For Ballnose Tools for example is the wrong value to use when calculating the correct rpm value to achieve a particular value of surface feet per minute (sfm) The diameter at which the tool cuts is determined instead by how much of the ball is engaged To calculate this effective diameter DEFF use the tool diameter D and the
