Long-Life Rubber-CushionedAbrasive Grinding Bits for Metals. A diamond abrasive that's bonded to a rubber cushioning makes these bits last 10 to 20 times longer than rubber-cushioned bits without diamond. Because they're cushioned during grinding, these bits produce a smoother surface texture than other bits with similar grits.

AISI grade 4340 alloy steel is difficult to be machined. Friction also affects tool-work and tool-chip interfaces adversely during machining. Due to friction, more temperature generated at both rake and flank faces. Less wear was found at low speed but as speed progresses more wear was observed for all nanofluids.

The AISI/SAE system uses a 4-digit number to identify the chemical composition of alloy and carbon steels. The first digit indicates the main alloying elements, the second digit the top grade elements, and the last two digits show the carbon content in hundredths of a percent. For example, AISI/SAE 1020 steel is a plain-carbon steel containing ...
