    • A process for chucking and machining an elongated cylindrical article made of a ceramic material according to the present invention, comprises the steps of: (1) chucking the elongated cylindrical ceramic article between chuck heads at longitudinally opposite end portions of said ceramic article; (2) holding the elongated cylindrical article between the chuck heads under such a low chucking pressure as allowing the ceramic article to slip inside a driven side chuck head while being kept inside the chuck heads at the opposite end portions, and slipping the ceramic article inside the chuck heads for a given time under rotation of a driving chuck head so that any positional deviation between the location of a center axis passing centers of of the chuck heads and an axis of the ceramic article may be removed due to a self aligning centrifugal action of the ceramic article; (3) raising the chucking pressure of the chuck heads to such a level as required for machining the ceramic article; and (4) then machining a surface of the ceramic article by a machining tool.

    • A sanding tool 10 includes a block 11 mounting an abrasive member 50, and a shroud 12 which extends around the block and includes a channel 20 which is configured to receive abraded dust. The abrasive member is configured to project beyond an outer edge region 16 of the shroud 12. The shroud further includes an outlet 21 which is connected to a source of suction, and at least one inlet 22 which is formed as an interruption in the edge region 16 of the shroud 12. In use, when the sander is located on a planar surface, and suction is applied to the outlet, air is able to be drawn into the channel over the edge region of the peripheral wall and the inlet is configured to introduce a draft through said channel to facilitate clearing of abraded dust from the channel to the outlet.

    • A wheel truing device for a centerless grinder comprises a first grinding wheel (4) for grinding a stem (24a) of a workpiece and a second grinding wheel (21) for grinding a head of the workpiece, respectively. The device also comprises:

      a first dresser (46) for truing the first grinding wheel (4);
      means for moving the first dresser (46) in a direction parallel with an axis of the first grinding wheel (4);
      first positioning means for extending or retracting the first dresser (46) in a direction perpendicular to the axis of the first grinding wheel (4) so that a truing surface of the first dresser (46) contacts with an outer circumferential surface of the first grinding wheel (4);
      a second dresser (60) for truing the second grinding wheel (21); and
      second positioning means for moving the second dresser (60) in the direction perpendicular to the axis of the second grinding wheel (21) so that a truing surface of the second dresser (60) may contact with an outer circumferential surface of the second grinding wheel (21).
    • 一种用于无心研磨机的砂轮修整装置包括用于研磨工件的杆(24a)的第一砂轮(4)和用于分别研磨工件的头部的第二砂轮(21)。 该装置还包括:用于修整第一砂轮(4)的第一修整器(46); 用于沿与第一砂轮(4)的轴线平行的方向移动第一修整器(46)的装置; 第一定位装置,用于沿着与第一砂轮(4)的轴线垂直的方向延伸或缩回第一修整器(46),使得第一修整器(46)的修整表面与第一研磨件(46)的外圆周表面接触 轮(4); 用于修整第二砂轮(21)的第二修整器(60); 以及第二定位装置,用于沿着垂直于第二砂轮(21)的轴线的方向移动第二修整器(60),使得第二修整器(60)的修整表面可以与第二研磨件(60)的外圆周表面接触 轮(21)。
