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 640mm dia. To achieve maximum stability and efficiency, the grinding wheel is mounted directly on the motor which is provided with fine screw cross adjustment. 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 knife is held on the knife carrier shaft either by arbor or direct fit if smaller bores are involved. 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.
