A predictive model of grinding force in silicon wafer

2016-10-1  Silicon wafer thinning is mostly performed by the method of self-rotating grinding. In grinding, the grinding force is a crucial factor of affecting the grinding performance, form accuracy and surface/subsurface thinning quality. To control the thinning quality of ground wafer, grinding force is the most essential factor need to be controlled.

Modelling and experimental study of roughness in

Axial rotating heat-pipe grinding wheel for

2020-8-1  Therefore, in this paper, an axial rotating heat-pipe profile-grinding wheel was designed, fabricated, and used for clean grinding of Ti–6Al–4V alloys without conventional flood coolant. By developing this heat-pipe profile-grinding wheel, a clean and sustainable grinding process will be achieved with less resource utilization, no harmful coolant, less cost for the process, and positive

Balance Quality of Rotating Equipment Miki Pulley

Set the balance quality grade according to the type of the rotor. The smaller the balance quality grade value, the higher the balance accuracy. However, special attention needs to be paid to G1 and G0.4 as mentioned in the JIS text. Obtain the allowable residual specific unbalance e per from the max. rotation speed at which the rotor is actually used. This can be obtained by the following calculation formula or

Investigation on cooling behavior of axially rotating

2021-1-5  When the RHP cooling method was applied, a low average grinding temperature was found. When coolant was applied, the grinding temperature is a bit higher than the case with RHP cooling, but was still kept in a low value of about 115 °C. When grinding without cooling, the average grinding temperature was much higher, approximately 580 °C.
