Aplicación del "método de ajuste de herramientas" en Fine Grinding
The main task of PCD fine grinding is to control the final dimension precision of grinding accurately and stable.Wheel wear, accurate positioning of edge tip grinding point and grinding resistance will eventually affect the machining accuracy. These factors have nothing to do with the movement accuracy of the machine but are related to when to start (that is, to the point of the tool setting), finish grinding and other issues and the monitoring of grinding state is closely related.
Although wheel wear is difficult to measure and the height of the insert (which affects the position of the grinding point ) is difficult to measure within a certain range, the control system with the voice-activated device can easily record the exact position of the insert tip and the wheel surface at the moment of contact. Taking this as the starting point, the relative feed can guarantee dimensional accuracy. We call this " tool setting method ".Of course, the premise of "tool setting method" is that the previous process has an accurate reference, or the dimension can be accurately measured before grinding. This can be done by CCD online measurement system. In the industry, when using the manual machine, the grinding process of the first back Angle of PCD tool (i.e. polishing edge) is as follows: on the basis of the dimension of rough grinding, grind 0.02~0.03mm further to form the blade of 0.05~0.1mm. This also happens to coincide with " tool setting method ".
