摘要： PURPOSE:To compensate the wear of a rest shoe by feeding a grindstone base and a work rest through a set program, and processing a workpiece by allowing the rest to further advance while measuring a workpiece diameter before the workpiece reaches a prescribed diameter. CONSTITUTION:A grindstone base wherein a grinding grindstone 1 is driven to turn is fed for grinding toward a workpiece 2. A work rest 4 equipped with a shoe 5 supporting the workpiece 2 on its tip is sent toward the workpiece 2. The grindstone and the work rest 4 are sent following a preset feed program. The diameter of the workpiece 2 is measured with a gauge 3 provided on the grindstone when the feed program is completed. When the diameter has not yet reached a predetermined one, the grinding is continued by allowing the work rest 5 to advance while measuring the diameter of the workpiece 2 with the gauge 3. When the diameter of the workpiece 2 reaches a predetermined value, the processing is completed.

摘要： PURPOSE:To make uniform the quantity of grinding with a grindstone, by altering the revolution speed of the surface of a cam as a function of the rotation angle of the cam. CONSTITUTION:A cam shaft 12 fitted with cams 14 at axial intervals is supported on a cam profile grinder 10 including a headstock and a tailstock. The profile of the cam 14 is shown in the drawing. While the bottom B of the cam 14 which is defined by a radius of R is in contact with a grindstone 16, the cam shaft 12 is rotated at a constant speed of VB so that the quantity of grinding of the cam with the grindstone is made uniform. The flat portions F1, F2 and protruded portion N of the cam 14 are ground at speeds of VF and VN, respectively. These revolution speeds, the feed of the grindstone 16 and the swing of the headstock and the tailstock are determined according to a predetermined program so that the quantity of grinding is made uniform.

摘要： PURPOSE:To have an uncomplicated way of dressing a grinding wheel with super abrasive grain by allowing a dressor, whose tip is provided with a grinding liquid supply hole and an exhaust groove, to have contact with the grinding wheel and by supplying a grinding liquid containing abrasive grain. CONSTITUTION:The body 6 of dressor is coupled with a shank 8, and the foremost part is provided with a correction end-face 10 consisting of diamond dust sintered with metal bond. The shank 8 and dressor body 6 are provided with a supply hole 9 for the grinding liquid which is open at the correction end-face 10. This end face 10 is also equipped with a radially oriented exhaust groove 11 for grinding liquid. This dressor is mounted on a moving arm 12 put in contact normally with the grinding face of the grinding wheel 5 to supply the grinding liquid containing abrasive grain through a piping 13. By dressing in such a way, correction of grinder wheels with super abrasive grain such as diamond and CBN can be easily made.

摘要： PURPOSE:To enhance effectiveness in the work by coupling a corrective feed motor with the feed drive system, which is to allow the wheel spindle stock to make the feed motion for cutting-in, through a differential gearing mechanism and thereby making easily correction of the stand-by position of the grinding wheel when a stepped part of the work with different diameters is to be ground. CONSTITUTION:A support shaft 4 is installed at a drive shaft 2 equipped with a pinion 3 to be coupled with the feed screw of wheel spindle stock, and is coupled with a pulse motor 13 for feed of the wheel spindle stock through bevel gears 5, 6 and gears 9, 11, 3. Another bevel gear 7 meshes with the bevel gear 5 on support shaft 4 to constitute a differential gearing mechanism. With this bevel gear 7 in fixed condition, the number of revolutions of the bevel gear 6 is sensed with an encoder 8 to control the pulse motor 13, and thereby the wheel spindle stock is supplied with a feed according to the grinding feed cycle. In case the processing diameter is changed and in case the diameter of grinding element is changed after dressing, a pulse motor for correction 18 shall rotate the bevel gear 7.
