The choice of tool material depends on the material to be cut as well as on the maximum spindle speed of the machine. Smaller milling machines may not be capable of reaching the spindle speeds recommended for carbide end mills. End Mill Coatings . The use of coatings will increase the surface hardness of the tool.

The industrial pin mill (also known as a universal mill, turbo mill, and impact mill) is a one pass grinding equipment ideal for achieving the micronization of bulk materials and powdered products. Common applications involve the fine grinding of sugar, salt, sodium bicarb, etc. The average achievable particle size range of the pin mill is around a d50 of 80 microns.

Material Costs. Let's start out looking at material costs. Given the issues make a plate larger than my machine's travels, I will be looking at dimensions of 34 x 12 x 3/4″. I will shoot for 4140 Pre-Hardened plate as well. I came up with quotes that ranged from $739 to $837 for Hardened and Ground Plate.

A material like aluminum produces large chips compared to other materials. For that reason, 4 flute end mills are rarely used with aluminum because the flutes can get jammed with chips and break the cutter. For harder materials, you want to use more flutes. Having more flutes reduces chip load and improves surface finish.

When you have thin pieces, the end mill's torque is more effective in potentially kicking off your material because it's lower and closer to the material's center of mass.Also for small objects, there's little adhesion keeping the bottom surface in place, raising the likelihood of the mill throwing the object off.Thus, it's important to design your piece with this in mind.

Consider using a corn-cob end mill, an end mill with little burred teeth rather than a standard fluted end mill. These bits take little tiny cuts out of your material rather than shaving away chips, preventing the foam from being pushed out of the way. Foam dust is very fine and sticks to surfaces. It is recommended to use a dust shoe.
