The machine has two motors, one to drive the knife carrier shaft and the second to drive the grinding wheel. The assemblies are mounted on a heavy and substantial cast iron base through which the knife carrier shaft passes carried on self lubricating bearings with grit excluders. The machine will accommodate circular knives of all designs and sizes up to 200mm dia dependant on the rate of required stock removal. This machine is designed essentially for knives at the smaller end of the range. Adjustments are made using quick release clamp levers. Accurate facilities are provided for all grinding angles, positive or negative using clearly graduated scales, and a vertical pillar at the rear of the machine provides adjustment for height and knife diameter. The rotating blade is fed into the grinding wheel automatically at a constant and adjustable rate, controlled by a ratchet and cam arrangement. The ratchet also incorporates a detachable slide which can be preset so that after a pre-determined amount of stock has been removed, feed will be automatically arrested. After locating the blade, the whole operation, which covers grinding, feed and limit, and deburring if requested, is automatic and the inaccuracies and variations of hand grinding are avoided.
