Is it advisable to attempt to filter or purify cutting lubricants?
If straight oil is used as a cutting lubricant, the filtering would be an economical process, but if using a compound composed of small percentage of oil and water, the process of cleansing is not economical. Cutting oil, as sold today, can be filtered very economically and profitably.
CUTTING SPEEDS (See also heading "Number of Cuts Necessary") Cutting speeds for Geometric Dies on cold-rolled steel and brass... work, about 1. 5" diameter stock?
We cannot give a hard and fast rule for cutting speeds, as conditions, such as the pitch of thread, chamfer of dies, lubricant used, finish required, shape and form of thread, also kind of stock, will govern the speed.
Some stock, supposed to be of the same grade, is harder than others.
However, an approximate speed for cutting cold rolled steel would be from 20 to 25 feet per minute, or from 50 to 65 R. P. M. For 1. 5" diameter stock, pitch between 10 to 32 threads per inch.
