The correct use of double disc grinding machine method

Double disc grinding machine is a high-efficiency surface processing machine tool, grinding out two parallel end faces at the same time in a processing process, according to the structure can be divided into horizontal and vertical two, according to the feeding method, and can be divided into serial, rotary disk, reciprocating. Due to the high precision and high consumption efficiency of the grinding products, it is widely used in many industries such as automobile and motorcycle, bearings, and magnetic materials.

The piston pin, piston ring, valve washer, connecting rod, cross shaft, valve plate, fork, hydraulic pump blade, rotor, stator, compressor slide, bearing inner and outer rings and rollers, magnetic ring, magnetic steel sheet, graphite plate and other materials of the automobile and motorcycle industry are suitable for processing. The method and precautions of the correct installation of the grinding wheel for the double end grinder series can be fastened by screws or binder between the grinding wheel and the long shaft.

The matching gap between the inner hole of the grinding wheel and the long shaft journal of the double disc grinding machine should not be too large or too small. Too small, easy to crack the grinding wheel; When it is too large, the grinding wheel is focused and causes vibration. The clearance between the grinding wheel and the long shaft is related to the fastening method, which should not exceed 0.2mm when fastened with screws and 0.3mm when fastened with adhesives. If the gap is too large, the insert paper can be inserted between the long shaft and the inner hole of the grinding wheel to reduce the gap.

The two end faces of the grinding wheel can not directly contact the shoulder and screw end face of the long shaft, and should be padded with yellow paper and other soft padding, the thickness of 0.2mm~0.3mm is appropriate. This can make the internal grinding wheel force average, fastening firmly. The end face of the long axis and the end face of the screw of the grinding wheel of the double disc grinding machine shall not be uneven, and the contact surface shall not be too small, otherwise the friction area will be reduced, and the reliability of the fastening of the grinding wheel cannot be guaranteed.
