Applications of High-Efficiency Abrasive Process with CBN Grinding Wheel

Abstract

High-efficiency abrasive process with CBN grinding wheel is one of the important techniques of advanced manufacture. Combined with raw and finishing machining, it can attain high material removal rate like turning, milling and planning. The difficult-to-grinding materials can also be ground by means of this method with high performance. In the present paper, development status and latest progresses on high-efficiency abrasive machining technologies with CBN grinding wheel relate to high speed and super-high speed grinding, quick point-grinding, high efficiency deep-cut grinding, creep feed deep grinding, heavy-duty snagging and abrasive belt grinding were summarized. The efficiency and parameters range of these abrasive machining processes were compared. The key technologies of high efficiency abrasive machining, including grinding wheel, spindle and bearing, grinder, coolant supplying, installation and orientation of wheel and workpiece and safety defended, as well as intelligent monitor and NC grinding were investigated. It is concluded that high efficiency abrasive machining is a promising technology in the future.

Development of a model of tool surface dressing when grinding with crossed wheel and cylindrical part axes

“…The method of high-speed grinding with crossed axes of the wheel 2 and part 1 [4,5] was performed by Junker on Quickpoint 1000, Quickpoint 3000, Quickpoint 5,000 machines [6]. Elbor or diamond grinding wheels with a height of 4-6 mm and a coating width h of several millimeters at speeds of the grinding wheel up to 140 m/s and the part rotation up to 12,000 rpm are used.…”

Mechanical strength increasing of abrasive reinforced wheel

“…Nowadays, a fairly large number of works of study on the processes of metal grinding have been carried out [5,6]. There are practically no works aimed at increasing the mechanical strength of abrasive reinforced wheels, which are widely used in cutting and cleaning operations.…”

Experimental Studies on MoS2-Treated Grinding Wheel Active Surface Condition after High-Efficiency Internal Cylindrical Grinding Process of INCONEL® Alloy 718

“…The introduction of advanced high-efficiency abrasive technologies into the modern machine, automotive, and aeronautic industries, as widely described by Hou et al and Wang and Li [1,2], forced the producers of abrasive tools to constantly improve them, as well as to search for more effective abrasive materials, allowing an increase of the efficiency and stability of the machining process and extending the tool life. One of the key factors with a decisive influence on the stable course of the grinding process [3] (and hence its efficiency) is the temperature increase in the grinding zone (GZ).…”
