The superabrasive grits cBN and diamond are a great deal more expensive than the conventional abrasives already mentioned. Thus, the construction of superabrasive grinding wheels is also different from that of conventional ones. A further reason for the altered construction has to do with the fact that such grinding wheels exhibit a higher wear resistance. […]

Material Properties as a Function of Heat Treatment
The amount, form and arrangement of the structural elements and thus the mechanical properties of steel can be adjusted to the requirements at hand by means of a defined heat treatment. Heat treatment is understood as a process in the course of which a workpiece or a workpiece section is exposed to defined temperature sequences […]
Construction and Structure
Metallic Titanium Titanium and titanium alloys have a low density (p = 4.5 g/cm3) and high tensile strength (Rm = 900 — 1400 N/mm2). They exhibit good heat resistance up to temperatures of ca. 500 °C. In addition, they are resistant to many corrosive media. From these properties are derived the main applications of titanium […]
Grinding
5.2 Preparation Grinding tools are not in a usable condition as delivered or after a longer period of use. Grinding wheels exhibit macrogeometrical faults (e. g. roundness deviation, waviness, macro-wear, loss of profile), which lead to problems in the grinding process or to deficient dimensional accuracy of the components worked upon. Micro-wear, i. e. dulling […]
Parameters
With the help of parameters or characteristics, grinding processes can be generally described independently of the grinding method used. For a methodologically comprehensive comparison of various grinding strategies, various process parameters were generated, which will be described in the following. Process parameters offer the grinding technician the possibility of comparing various methods and interpreting the […]
