摘要： PURPOSE:To eliminate uneven wear and damage further the generation of disorder, by providing plural rotary dressers to be arranged spacing a predetermined distance and setting peripheral surface grinding wheel sides of the dressers so as to form almost the same projection figure to the peripheral surface shape of a grinding wheel so that plural abrasive surfaces are corrected by one time operation. CONSTITUTION:A device, which provides rotary dressers 5a, 5b successively spacing a predetermined distance to be arranged in a direction of the peripheral tangent A of a grinding wheel 10, sets a peripheral surface grinding wheel side, when it is projected in the direction of the tangent A, of these dressers so as to form almost the same shape to the peripheral surface shape of the grinding wheel 10. And the device, if the grinding wheel 10 is moved as shown by an arrow head B in the drawing, first corrects one abrasive surface 10b by the rotary dresser 5b next the other abrasive surface by the dresser 5a. Accordingly, the device enables the plural abrasive surfaces of the grinding wheel 10 to be corrected by one time operation while prevents the rotary dressers 5a, 5b from unevenly wearing, and damage in the peripheral surface and the generation of disorder can be eliminated by exchanging or correcting only the dressers 5a, 5b.

摘要： PURPOSE:To continuously carrying out dressing work on a grinding surface of a grinding wheel while carrying out grinding work on a work by arranging a bell crank one end of which is connected to a connecting ring and on the other end of which a dresser holder is provided. CONSTITUTION:Following rotary motion of a variable long crank 2, a bell crank makes oscillating motion at oscillating angle theta around a point O12 as its fulcrum. Consequently, a lever part 12 provided on one side of the bell crank makes the same oscillating motion, and accordingly, a dresser 7 stored inside of a dresser holder 11 provided on the head end part of the lever part 12 makes approximate linear motion in the radial direction. That is, in the radial direction of a grinding wheel 99, the approximate linear motion is made. Consequently, a grinding surface of the grinding wheel 99 making rotary motion is uniformly and continuously dressed and a work 95 is ground by the grinding wheel 99.

摘要： PURPOSE:To quantitatively grasp a dressing condition and surely carry out the optimum dressing by stopping dressing when a statistic value becomes below a defined value for each defined period of a detected discharging current value. CONSTITUTION:A switch 56 is closed by a switch control circuit 58 for a short time for each defined period T at the end of grinding of a grinding wheel 1, and the maximum value of the voltage V1 which is inputted during this defined period T is held by a peak hold circuit 5 and outputted. The output voltage V2 therefrom is inputted into a low-pass filter circuit 6 and smoothed. The smoothed voltage 3 is inputted into a comparing circuit 7, where it is compared with a constant voltage VA and, when the smoothed voltage V3 becomes lower than the constant voltage VA, a comparing output of level '1' is generated, thereby exciting a relay 82 and opening a normally closed contact to stop the feed of power to a motor 8. Thereby, the feed of the grinding wheel 1 is stopped at the point of time of the optimum dressing condition, to complete dressing.

摘要： PURPOSE:To make highly accurate dressing at an acute angle and accuracy retension attainable, by depositing rectangular sectional abrasive grains of a top side angle each being smaller than that of a furrowlike convex section alternately on both sides on the top of a furrowlike projecting part. CONSTITUTION:In each of abrasive grains, an angle at the side of a top part 14a is formed into an acute angle being smaller than that at the side of a top part 12a of a furrowlike convex part 12 of a dresser body 11, and height from the top part 14a is formed to be higher than that from the tip part 12a of the furrowlike convex part 12. In addition, a bae part 14b and a side part 14c are set up in the convex part 12 in the state that they are embedded in the furrowlike convex part 12, while another side 14d is exposed alternately to each of sides 12b and 12c, and the tip part 14a is situated on the top part 12a. Therefore, dressing for a grinding wheel is accurately performable at an acute angle and in addition, since the base part 14b of each abrasive grain 14 and the side part 14c are embedded in the furrowlike convex part 12, holding force of each abrasive grain is large enough, whereby a drop of each abrasive grain is kept back and the specified dressing accuracy is maintainable for a long time.

摘要： PURPOSE:To enable partial exchange of a part where wear is progressed, by a method wherein the outer periphery part of a dresser is axially divided, dresser members are classified into a dresser member for rough dressing and a dresser member for finish dressing, and the dresser members are combined together in a multilayer manner. CONSTITUTION:When a grinding stone G is dressed as a dresser D is traversed in an axial direction A, dressing is effected in a way that the dresser is progressed in a manner that diamond grinding grains 1b of a dresser member 3 for rough dressing crush grinding grains 5 on the grinding stone G side and diamond grains 1a of a dresser member 2 for finish dressing smooth the grains 5 on the crushed grinding stone G side. Dressing of the grinding stone G is affected in a manner described above, and when wear of the dresser member 3 for rough dressing is progressed due to the use for a long time, a fastening bolt 4 is unfastened, the existing dresser member 3 for rough dressing is removed from the dresser member 2 for finish dressing and is replaced with a new dress member, and dressing is performed in succession.

摘要： PURPOSE:To reliably attach and fix abrasive grains in a single layer by filling abrasive grains between a casing and covers then circulatively feeding an electrodeposition liquid to an enclosed space under a pressed state for the machining grindstone of a negative electrode sealed and set in the casing of a positive electrode. CONSTITUTION:In the manufacturing device 6 of a machining grindstone, a screw type grindstone base material 1 is set between a casing 3 and covers 9, 9', and abrasive grains 5 are filled into an enclosed space 4 formed between the casing 3 and covers 9, 9' and having a ring-shaped cross section. An electrodeposition liquid 25 is filled into the enclosed space 4 under a uniformly pressed state. The hydrogen gas generated here is discharged to an electrodeposition liquid tank 24 together with the electrodeposition liquid 25 and floated and removed, thus electroplating is accelerated under a uniform and stable state. Accordingly, abrasive grains in a single layer can be correctly deposited and formed on all shape faces even if the outer shape of the grindstone base material 1 is complex.
