The upper surface 3 of. Fu;. 17. the base makes up the sliding ways, over which cross-feed car-riage 4 is moved by means of a hydraulic cylinder and piston,similar in principle to that used on grinders, located below thecarriage cover 4. When the carriage moves for operating theburr, it slides along way 7. Water under high pressure is sup-plied to the cylinder by means of hose connections to carriage for GRINDERS AND GRINDING 29 both inlet and outlet water at 5 and 6. The burr-feed motor isshown mounted on top of the cross-feed carriage. This dresser is macle of four essential parts: the feed motoror hydraulic cylinder 8, which forces burr against stone; the handwheel 9, for controlling depth to which the burr is allowed to cutinto the stone; the automatic return mechanism 10, controllingthe return of the carriage to starting point and the withdrawalof the burr from contact with the stone; and the valve 11, for start-ing and stopping the hydraulic lathe in operation. The burr,in another type of holder, is sh
