摘要： PROBLEM TO BE SOLVED: To provide a grinding device able to control the grinding wheel width with constant precision. SOLUTION: When an end surface of a work is machined, the cutting position of a grinding wheel 22 is stored, while, at the completion of the machining, the end surface of the work is detected in contact with a feeler 54, and the contact position is stored. Based on a difference between the cutting position and the contact position, a relative distance between the end surface G1 of the grinding wheel and the feeler 54 is calculated. After this, a difference between the relative distance as an initial value and the relative distance calculated at present (the amount of actual decrease in the width of the grinding stone) is calculated. Then, based on the amount of decrease in the grinding wheel width, the grinding wheel width data are corrected.

摘要： PROBLEM TO BE SOLVED: To reduce cost and time and improve accuracy all required in manufacturing eccentric cylindrical pins. SOLUTION: While a workpiece is rotated clockwise around an axis of rotation C after a cylindrical journal B is so chucked that a point OB on its center axis is positioned on the y-axis, the height (h) of a point (p) is measured optionally many times. This provides that angle of rotation Ψ of a point P giving the height (h) a maximum value H which is measured with respect to the point OB in a counterclockwise direction on the axis of rotation C. The application of the cosine formula to a triangle OAOBC develops: ε=ScosΨ±(E2-S2sin2Ψ)1/2. The height S of the center axis of the cylindrical journal B from the axis C of rotation is measurable in known techniques. The calculation of the eccentricity εthrough, by way of example, the measurement of the angle of rotation Ψof the point P in that manner in turn offers accurate x-y coordinates of the center axis of a cylindrical pin A, which is then afforded high-precision grinding.

摘要： PROBLEM TO BE SOLVED: To make a linear motor driving and feeding device of a machine tool compact and further prevent thrust required for machining from being reduced. SOLUTION: A moving base 15 supporting a tool G for machining a work piece W is guided and supported to a base 12 so that the moving base 15 may be reciprocated. By a linear motor 16 constituted of a primary motor element 16a and a secondary motor element 16b opposed to each other, the tool G is reciprocated between an advancing position where the tool G is abutted on the work piece W and machining this work piece W and a retreating position where the tool G is separated from the work piece W. Either one of both of the motor elements 16a and 16b is shorter than the other in length of the reciprocating direction. The motor elements 16a and 16b are arranged so as to be completely opposed in the reciprocating direction at the advancing position to be a stroke range to be used for machining of all stroke ranges of the moving base 15 and so as to be partially opposed at the retreating position to be the stroke range which is not used for machining.

摘要： PROBLEM TO BE SOLVED: To delay occurrence of 'shear drop' in an arc part of a grinding wheel caused by difference in removal quantity between a cylindrical material and a shoulder part and between the cylindrical material and a corner part by sticking a grinding wheel of high grinding rate to a part corresponding to the shoulder part and the corner part rather than the cylindrical part. SOLUTION: A grinding wheel 1 is composed of a ring first grinding wheel layer 3 which grinds a cylindrical part 41 of a pin P of a crankshaft, W and a segment forming second grinding layer 4 which is stuck to the outer circumferential part, of both side faces of the grinding wheel layer 3 and grinds a shoulder part 42 and a corner part 43 of the pin P. The second grinding layer 4 is formed of different grain sizes and materials of abrasive grain, for example, a CBN grinding wheel or a diamond grinding wheel so as to enlarge the grinding rate compared with the first grinding wheel layer 3 and an arc part 5 having an almost same arc as a desired one is formed in the tip part corresponding to the corner part 43 of the pin P.
