摘要： A method and apparatus for grinding a cylindrical surface of a workpiece by a traverse movement of a grinding wheel having a relatively narrow grinding surface. To improve the cylindricity of cylindrical surface, the traverse grinding is divided into a rough traverse grinding and a finish traverse grinding. In the rough traverse grinding, a traverse girding is carried out with a large depth of cut which would causes a deterioration of the cylindricity at one end of the cylindrical surface. In the finish traverse grinding, a traverse girding is carried out with a small depth of cut to improve the cylindricity. In another embodiment, one of grinding conditions such as the traverse speed of the grinding wheel, the rotational speed of the workpiece and the peripheral speed of the grinding wheel is changed when the grinding wheel approaches an end of the cylindrical surface at which the traverse grinding ends so as to make the grinding force constant, thereby improving the cylindricity of the cylindrical surface. In other embodiments, the position of the wheel head is compensated based upon the measured diameter of the cylindrical surface so that the entire area of the cylindrical surface has a desired diameter. This compensation also improves the cylindricity of the cylindrical surface.
摘要翻译：一种用于通过具有相对窄的研磨表面的砂轮的横移来研磨工件的圆柱形表面的方法和装置。为了提高圆柱面的圆柱度，横向磨削分为粗加工磨削和精加工磨削。在粗加工研磨中，以大的切割深度进行横向加工，这将导致圆柱形表面的一端的圆柱度的劣化。在精加工磨削中，以较小的切削深度进行横向加工以提高圆柱度。在另一个实施例中，当研磨轮接近圆形表面的端部时，磨削条件（诸如砂轮的横动速度），工件的转速和砂轮的圆周速度之一变化，使磨削力保持恒定，从而提高圆筒面的圆筒度。在其他实施例中，基于圆柱形表面的测量直径来补偿轮头的位置，使得圆柱形表面的整个区域具有期望的直径。该补偿也提高了圆柱面的圆柱度。

摘要： A grinding wheel for grinding a workpiece has a first grinding surface and a second grinding surface successive thereto. The first and second grinding surfaces are parallel to and inclined with respect to the rotational axis of the workpiece, respectively. A diameter of the workpiece to be ground in a next grinding operation is measured in advance. An angle to be formed between the second grinding surface and the rotational axis of the workpiece is selected based upon the measured diameter of the workpiece. The selected angle is established between the second grinding surface and the rotational axis of the workpiece. The grinding wheel is moved relative to the workpiece in a direction of the rotational axis of the workpiece, whereby the cylindrical surface of the workpiece is firstly ground by the second grinding surface and subsequently ground by the first grinding surface of the grinding wheel.

摘要： A grinding wheel which is formed from super hard abrasive grains is trued by traverse-feeding a truing tool a plurality of times (n). Among the (n) traverse feeds of the truing tool, every traverse feed except for the final (i.e., from the first to the (n-l)th traverse feed) is carried out with an infeed which is set at a relatively small value in order to remove any deflection of the grinding wheel. In the final traverse feed, the infeed of the truing tool is set at a relatively large value in order to form an excellent cutting edge on the grinding wheel. Accordingly, any deflection of the grinding wheel is removed by a plurality of traverse feeds of the truing tool carried out with a relatively small infeed, and a cutting face having an excellent cutting ability is formed on the grinding wheel by the final traverse feed carried out with a relatively large infeed.
摘要翻译：由超硬磨料颗粒形成的砂轮通过遍历进给多次（n）的修整工具进行修整。在修整工具的（n）横向进给中，除了最终（即，从第一到第（N1）横向进给）之外的每个横向进给都是按照相对较小的值按顺序设置的进给来执行的以消除砂轮的任何偏转。在最终的横动进给中，为了在砂轮上形成优良的切削刃，修整工具的进给被设定为相对较大的值。因此，用相对较小的进给量进行的修整工具的多个横动进给器去除了砂轮的任何挠曲，并且通过最终横动进给在砂轮上形成具有优良切削能力的切削面具有相对较大的进给。

摘要： An apparatus for successively truing and dressing a grinding wheel made of cubic boron nitride (CBN) with a diamond-impregnated truing roll and a metal dressing roll. The truing and dressing rolls are rotatably mounted on a roll carriage which is slidably mounted on a grinding machine so as to feed the rolls toward the CBN wheel and thereafter traversely move the rolls along the wheel surface of the CBN wheel. After truing with the truing roll, a coolant fluid mixed with liberation abrasive grain is supplied toward a gap of a predetermined distance, smaller than the mean size of the abrasive grain, which is established between the CBN wheel and the dressing roll, so that the liberation abrasive grain acts to grind and remove bond material from the wheel surface in order to accomplish the dressing of the CBN wheel.

摘要： In a grinding wheel in which abrasive tips for rough grinding and abrasive tips for finish grinding are alternately bonded to a periphery of a disk type base rotating about a rotation axis, each abrasive tip includes the abrasive layer formed by bonding abrasive grains and a lower layer overlaid and integrally for led with the abrasive layer. The abrasive tip is attached to the periphery of the base at the lower layer. A Young's modulus of the lower layer of the abrasive tip for finish grinding relative to a load acting on the grinding surface of the abrasive tip in an inward direction of the grinding wheel is less than that of the abrasive tip for rough grinding. Thereby, the surface of a workpiece can be both rough-ground and finish-ground with superhigh-precision surface roughness with using one grinding wheel.
