Since grinding comprises both cutting and sliding, it is necessary to provide a balanced environment of heat extraction and lubrication. Thus it requires a controlled grinding environment such as MQL. The current study is an experimental investigation on the significance of the MQL parameters on grinding performance of Inconel 751.
To dissipate grinding heat in the contact zone and guarantee workpiece surface quality, a novel cooling method that dissipates grinding heat assisted by forming rotating heat pipe inside the grinding wheel (HPGW) is proposed. Tests were performed to determine its heat transfer capacity in high-efficiency grinding of Inconel 718 alloy.
Sep 21, 2004· AEROBOR(TM) high-porous vitrified CBN grinding wheels were tested recently by one of world's majour turbine building company for the grinding of turbine shroud segments made of AMS5666 Nikel-based alloy (Inconel 625). Up until now with the grinding of "hot section" segments, a CBN plated wheel has been used to remove the bulk of the material to ...
Inconel's high temperature strength is developed by solid solution strengthening or precipitation hardening, depending on the alloy. Inconel alloys are typically used in high temperature applications. Common trade names for Inconel Alloy 625 include: Inconel 625, Chronin 625, Altemp 625, Haynes 625, Nickelvac 625 and Nicrofer 6020.
