The proven precision - grinding machines for valve seats with Ø up to 200 mm.. Condition: used. Operating principle: A clamped in the valve guide pilot centered the machine. For grinding of the valve seat, the grinding wheel is positioned in front of the inner edge of the valve seat and the desired depth of cut. After switching on the machine, the valve seat is automatically rounded. The driven at a high speed grinding body executes a circular movement around the valve seat and at the same time a cross feed movement across the valve seat. The valve seat is thereby inevitably ground on the predetermined seat angle concentric with the valve guide. Characteristics: The grinding head is equipped with a corresponding seat angle 30 ° arranged guide and optionally with a further corresponding to the seat angle 45 ° arranged guide. The powerful grinding spindle can optionally be used in one or the other guide. The drive of the grinding head is carried by a direct current motor with infinitely variable speed. A housed in the wheelhead feed gear causes at the revolving movement of the grinding head, a continuous feed movement of the grinding spindle. In the SB 3, a dressing device is provided on the grinding spindle, with which the abrasive article may be dressed quickly. The required for centering the engine pilot is adapted to the valve guide of the respective engine type.
