In Rockwell testing, the minor load is 10 kgf and the major load is 60, 100 or 150 kgf. In superficial Rockwell testing, the minor load is 3 kgf and major load is 15, 30 or 45 kgf. In …

CPM MagnaCut – The Next Breakthrough in Knife Steel

The hardness tables seemed dominated by 60 – 61.5 Rc values, and the edge retention looked much lower than all the existing premium steels, the S60/90/110V, etc. But I need to look more carefully. I didn't know that it was rare to get the sort of full spectrum of data you posted.

Grinding wheels and HSS

Grinding wheels and HSS. by Harold_V » Mon Jan 15, 2007 11:35 am. Successful grinding of HSS toolbits is best achieved by the use of a wheel that is readily friable and open in structure to insure free cutting and proper removal of swarf. Grain selection can be a matter of choice, but is often dictated by the availability of wheel …

Rockwell Hardness

Hardness Testing. G. Sundararajan, M. Roy, in Encyclopedia of Materials: Science and Technology, 2001 1.1 Rockwell Hardness Testing. In a Rockwell hardness test, initially a minor load of 10 N is applied and the zero datum position is established. The major load (60, 100, or 150 N) is then applied for a specific period (a few seconds) and removed, leaving …

The Brinell Hardness Test consists of indenting the test material with a 10mm diameter hardened steel or tungsten ball subjected to a load of 3000 kg. For softer materials, there are alternate scales using a 1500 kg or 500 kg load to avoid excessive indentation. The full load is applied for 10 to 15 seconds for iron or steel and at least 30 ...

Principle and Applications of the Rockwell Method

Application. 15N. Brale. 15 kgf (3kgf) Rockwell superficial scales use lower loads than a regular Rockwell test and are used to test materials too thin or small for the regular scales or outside the normal ranges. Generally, diamond indenters are used for hard materials, while Ball indenters are used for soft materials.

Grinding Balls and Other Grinding Media: Key consumables

Tower Mills: 0.5"-1.5" grinding balls are recommended. The normal top size of media used is 10-25mm, but even smaller grinding balls can be used for very fine grinding. Isa Mills: <0.1" grinding balls are recommended. The Isa Mill is more efficient when using small media (i.e. high-chrome steel balls).

Understanding the Hardness of Metals | designnews

For softer aluminum, you may need to use the Rockwell E scale (1/8-inch diameter ball with a 100 kg load) or the Rockwell F scale (1/16-inch diameter ball with a 60-kg load). Generally, the larger the indenter or the smaller the load, the better a scale will be for soft materials.

To make best use of CBN, cutting parameters must be maintained within a tight band. Speeds around 160 sfm and feeds of just 0.004 to 0.006 inch per tooth appear slow, but they are highly productive when machining sintered materials. Exact machining parameters are best determined by 30- to 60-second test cuts.
