Fig. 121 represents a hand geared lathe centre grinder, while in fig. 122 it is seen fixed to the tool base of a lathe ready for use. It can be fixed in any lathe, no alteration thereon being required. It consists of a small sapphire corundum wheel A, mounted between plates upon a steel spindle, driven through a pinion by the handle B. When grinding, the corundum wheel is moved horizontally by means of the hand lever C.
Mode of operation.—The stalk D carrying the apparatus is clamped upon the slide rest in exactly the same manner as an ordinary turning tool would be, taking care that the centre of the corundum wheel A coincides with that of the lathe centre. The angle to which it is necessary the centre should be ground is then obtained by slackening the centre pin E. The grinding wheel is then revolved at a very high speed by turning the handle B, at the same time moving the spindle horizontally by means of the lever C. |
