Kühlschmierung beim Keramikschleifen

1995 , Spur, G. , Brücher, T.

In order to optimize the grinding process of advanced ceramics it is of vital importance that the cutting fluid system is constructed according to the demands. One the one hand, the grinding process and the working result are considerably influenced by cooling lubrication. On the other hand, apart from merely technological aspects the layout of machining processes has increasingly to consider ecological and safety aspects In this connection the influence of the cutting fluid and the supply are explained for pendulum surface grinding of HPSN. Furthermore, a method for the selection of cooling lubricants is presented taking also ecological physiological and economical aspects into account. Additionally, recommendations for a technologically and ecologically favorable configuration of the cutting fluid supply are given.

Möglichkeiten und Grenzen des Hochleistungsbandschleifens

1993 , Spur, G. , Becker, K.

Das Hochleistungsbandschleifen ist konventionellen Fertigungsverfahren heute ebenbürtig. Mit einer Zerspanungsleistung, die der des Fräsens oder Drehens entspricht, kann sehr genau in bezug auf Maß und Form gearbeitet und eine hohe Oberflächenqualität erzielt werden. Um das Potential des Bandschleifens voll ausschöpfen zu können, müssen die Zusammenhänge zwischen den Prozeßgrößen bekannt sein.

Cutting fluids in grinding of advanced ceramics

1995 , Spur, G. , Brücher, T.

Due to the call for a better environment and health compatibility of production processes, cutting fluids are getting more and more important in grinding. Thus, technological as well as ecological and physiological aspects have to be taken into account, when an appropriate cutting fluid is chosen. The influence of various cutting fluids on the basic material removal and grinding wheel wear mechanisms and the resultant process and parameters are analyzed for the grinding of advanced ceramics. Moreover, in order to fit the ecological and physiological, as well as the technological requirements, the cutting fluid selection is assessed in view of a number of relevant criteria. As a second approach for an ecological and physiological compatible grinding process results for dry grinding of advanced ceramics are presented.

Einfluß der Schleifbandspezifikation beim Bandschleifen mit Stützplatte

1993 , Spur, G. , Becker, K. , Stark, C. , Schäfer, H.

The paper presents the results of the investigations carried out by the Institut für Werkzeugmaschinen und Fertigungstechnik (IWF) of the Technical University of Berlin on the subject of the influence of the abrasive belt specification during belt grinding with bolster plate. The objective of this investigation was to analyze the influence of the grain type, grain size and of the grinding belt system (conventional single layered, compact grain and hollow sphere abrasive multi-layered) on tool wear, the work result and the grinding forces.
