    摘要： A wheel dresser having a diamond point carried by a slider supported on an arm swung from the top of a column support and adapted to have its lower end swing into engagement and rest against a gage block supported against the column. The arm has a cylinder attached to its lower end that engages the gage block to provide a positive precision locating device for the arm so that a sine bar is formed by the arm supported on the column.

    摘要： A grinding machine for grinding a helical groove in a workpiece of tapering axial section, to give a conical cutter, has means for rotating the workpiece at a varying rate as it is advanced towards the grinding wheel. The rotating means includes a pinion in the workhead engaging with a rack extending across the machine. The rack is connected to a slide lockable in position along a pivotal arm, so that the end of the rack follows a circular path as the workpiece is advanced.
