The volumetric portion of grit VG, of bond VB and of pores VP of the total volume of the grinding component V is described by the equation v = V* + v, + Vp (3.5) If the individual columns are referred to the total volume V of the grinding component, we obtain the so-called structural […]

Influencing the Material Properties of Steels
Materially speaking, the machinability of steels is determined by its structure and mechanical properties (hardness, tensile strength). Of primary importance for the composition and thus for the mechanical properties as well are: • carbon content (C-content), • alloying elements and • heat treatment. The percentile amounts of carbon or other alloying elements given in this […]
Properties and Uses
Nickel-based alloys are highly temperature-resistant, resistant to corrosion and also very tough. Thus, they are presently the more often exploited material for components that are exposed to non-uniform mechanical strains at working temperatures up to 1100 °C. Because of their high heat resistance, thermal fatigue resistance and oxidation resistance in the high-temperature range of aviation […]
Cooling Lubricant Supply
The efficiency of the cooling lubrication is not only determined by the cooling lubricant’s physical and chemical properties, but also by the method of supplying the fluid into the cutting gap. For a sufficient supply of the contact area with the cooling lubricant, the cooling lubricant volume rate, the cooling lubricant discharge speed and the […]
The Depth of Dressing Cut aed
The depth of dressing cut aed is used for stationary dressing tools and diamond form rollers. It acts directly upon the dressing chip thickness. At higher depths of cut, the initial effective surface roughness of the grinding wheel increases along with the dressing forces. For dressing cBN and diamond grinding wheels, which are highly resistant […]
