Surface Peripheral Plunge Grinding

Turbine blades in jet engines are exposed to high levels of mechanical and thermal stress. The materials used must be highly heat-resistant and possess a high level of creep and rupture strength. Nickel-based forging alloys, those high-temperature properties are based on the mechanisms of mixed crystal, separation and carbide hardening, are especially suited to this. […]

Examples of Application

7.4.1 Plateau Honing The goal of plateau honing is to achieve a defined surface topography character­ised by periodically appearing deep honing traces with interjacent, fine bearing surfaces called plateaus (Fig. 7-33). This surface topography is achieved in two phases. In addition, the workpiece is pre-honed with coarse-grained diamond hon­ing stones, e. g. D 150, or […]

The Abrasive Carrier

Abrasive carriers have the task of receiving the abrasive in the form of slurrys or pastes in even distribution on their surfaces and binding them loosely. The re­moval and smoothing process must be supported by the abrasive carrier without the latter being involved in the process directly. This is the condition, chiefly, for a profiled […] Environmental and Machine Noises as Sources of Disturbance

It is indispensable for the reliability of the attributes derived from the acoustic emission that the noise emissions stemming to the operation of the machine, which are not directly related to the machining process, are stationary and separa­ble from the process noise. Fig. 10-5 shows an assortment of relevant emission sources in grinding ma­chines. Measurement […]

. Continuous Profile Grinding

In continuous profile grinding, a globoid-shaped grinding worm serves as the grinding tool. As opposed to continuous generating gear grinding, the globoid­shaped grinding worm does not have a tooth rack profile as its reference profile, but rather the contour of a tooth flank. Since we are dealing with a profile grinding process, contact between the […]


Honing is a cutting process with bonded grain and is used to improve the form, dimensional precision and surface quality of a workpiece under constant surface contact with the tool. In general, honing is applied after precision machining (e. g. grinding). Tables 7-1 and 7-2 illustrate the different honing techniques and their main fields of […]

Gear Honing of Externally Toothed Spur Gears with an Internally Toothed Tool

Gear honing is a fine machining process for gears which was originally imple­mented after grinding in order to create low-noise surface patterns on the tooth flanks. In the process, small allowances of approximately 15 pm were removed from the flanks. In further developments, this procedure came to be used directly after hardening, eliminating grinding from […]


The mechanisms which ultimately effect material removal take place on the boundary surfaces between the polishing grains and the workpiece surface. The abrasives in table 8-2 have proved effective for the polishing of metallic and hard — brittle materials. Table 8-2. Abrasives used for the processing of metals, hard and brittle materials and glass [WASC93] […]
