The main rotation motion of the honing machine tool is controlled by a variable frequency motor frequency converter, achieving stepless speed change of the spindle. The reciprocating and introduced motion of the honing machine are controlled by a servo motor. The reciprocating speed can achieve stepless speed change. The reciprocating stroke position is accurate and has high accuracy. The honing machine can achieve local stopping in the reciprocating position and can perform local honing. The spindle feed system driven by a servo motor provides high-precision quantitative feeding, with accurate and reliable feeding. It can achieve automatic feed compensation and is used for honing the surface of related workpieces. At the same time, the honing tool ｏｒ workpiece will perform relative rotation and axial linear reciprocating motion simultaneously.
During the machining process, the oil stone of the honing head is fed radially under the action of the expansion and contraction mechanism, gradually processing the workpiece to the required size. Most honing machines are semi-automatic, often equipped with automatic measuring devices, and can also be included in the work of automatic production lines. In addition to honing machines for machining holes, there are also cylindrical honing machines, bearing raceway honing machines, flat honing machines, and curved honing machines for machining other surfaces. Thus achieving honing. The feeding method of the honing head is mainly divided into quantitative feeding and constant pressure feeding. During quantitative feed honing, the feed mechanism expands the feed at a constant speed, forcing the abrasive particles to enter the workpiece. When the cutting force decreases due to blockage of the oilstone, the feed rate is greater than the actual grinding amount, and the honing pressure increases, causing the abrasive particles to fall off, break, and enhance the cutting effect. When feeding under constant pressure, due to the uneven surface of the workpiece, it is necessary to adjust the feed amount of the honing head in real time to ensure that the workpiece bears a constant grinding force.
