Title: Grinding working machine
Inventor: ENDO TAKAHIRO
IPC: B24B7/04
Filed: 1987-05-30
Abstract: PURPOSE:To work the step difference plane and starting-up surface of a workpiece having a step difference with high accuracy by providing each feeding mechanism in the axial direction onto one among a work arranged in parallel to a revolution shaft and a spindle for grinding and in the direction perpendicular to the shaft onto the other and alternately operating the both mechanisms. CONSTITUTION:A work spindle 3 and a grinding spindle 6 are shifted relatively in the X and Y directions. Therefore, the relative position of the workpiece 1 and a grindstone rate 5 can be set arbitrarily. Therefore, the workpiece 1 having the step difference of a cylindrical surface is installed onto a chuck 2 so that the revolution center of the cylindrical surface becomes concentric to the revolution center of the spindle 3, and the grinding spindle 6 is shifted in the vertical direction to the revolution shaft, and then grinding is performed by feeding the grinding spindle 6 in the axial direction and the direction perpendicular to the shaft, and the step difference plane and the starting-up cylindrical surface of the workpiece 1 having the step difference can be ground. Further, since the accuracy of the worked shape on the step difference plane is influenced only by each guide accuracy of two shafts in the X and Y directions, the accuracy can be improved drastically.

Filed: 1994-06-20
Abstract: PURPOSE:To detect to which injection valve abnormality not to inject a given amount of fuel occurs by deciding whether or not abnormality occurs to each injection valve through comparison of a fuel pressure lowering amount, estimated by an estimating means, with an actual fuel pressure lowering amount detected by a pressure detecting means. CONSTITUTION:A fuel pressure PA in a pressure accumulating chamber 2 right before an opening command for a corresponding injection valve and a fuel pressure PB right after a closing command are detected by a pressure sensor 11.
