In November, 1909, Machinery was published a description of a No. 1 surface grinding machine developed at that time by the Wilmarth & Morman Co., 1180 Monroe Ave., N. W., Grand Rapids, Mich. This machine has since then been completely redesigned, and is now furnished with an adjustable swivel sub-table, as shown in the accompanying illustration, an improvement which provides a means of conveniently and accurately handling certain grinding operations. It particularly adapts the machine for grinding work of angular or irregular shape, as it is unnecessary to remove the work from the table and reset it in order to procure the proper angle. This is accomplished by swiveling the sub-table which has suitable graduations to enable close adjustments to be made. The sub-table is also provided with T-slots for attaching a headstock and a tailstock, or a dividing head, when grinding work held between centers. The wheel can also be trued without disturbing the work on the table, by means of a built-in truing device permanently located on the wheel hood. The machine is especially recommended for use in accurate gage or die work. |
