TYPES OF GRINDING FLUIDS

Grinding fluids are commercially available with different property profiles to meet the requirements of specific machining tasks. DIN 51 385 divides grinding fluids into • Water-immiscible • Water-miscible • Water composite fluids The more general fields of application of cooling lubricants are cutting and partial forming processes [DIN 51 385]. Water-immiscible cooling lubricants are generally […]

PHYSICS OF GRINDING CERAMICS

The material-removal rates in grinding of ceramics vary widely depending on the application (Figure 14.5). With recent advances toward understanding of the mechanics of grinding ceramics, it is possible to achieve material-removal rates comparable to that in metal grinding. However, current practice achieves only about a tenth of these material-removal rates. FIGURE 14.6 Surface contact. […]

POWER AND STIFFNESS REQUIREMENTS FOR ROTARY DRESSERS

A review of some commonly available dresser spindles, sold to machine tool builders and as retrofits for grinders previously using single point dressing, gives a good indication of the power require­ments and hence stiffness. Table 15.2 lists the capacity of various Wheel Dressing and Norton (Divisions of Saint-Gobain Abrasives) dressing spindles. The first observation is […]
