The quality of honing reciprocation control means directly determines the precision and efficiency of honing processing, and cross-hatch formed after honing reciprocation plays a special role in oil lubrication of an engine cylinder body or a cylinder sleeve, so that the working condition of a coupling piece during high-speed movement is greatly improved, and the key effects of improving the running speed, prolonging the service life and saving energy are achieved. In a numerical control system, the precision of honing processing can be improved by adopting a scientific reciprocating control technology.
In the honing control processing process of the numerical control system, the most commonly used honing reciprocation control mode is to use the reciprocation upper reversing position as a starting point of forward reciprocation of the honing head and the reciprocation lower reversing position as an end point of forward reciprocation of the honing head. The reciprocating lower reversing position is used as a starting point of the reverse reciprocation of the honing head, and the reciprocating upper reversing position is used as an end point of the reverse reciprocation of the honing head. The method is characterized in that the reciprocating motion from top to bottom is defined as forward reciprocating, the reciprocating motion from bottom to top is defined as reverse reciprocating, and the upward and downward changing positions of the honing head are not changed in the control process of the honing motion, so that the honing process is carried out by adopting the method, a good process of processing the cylindrical hole on the inner surface can be obtained, and the roundness of the inner hole is improved.
In the process of the matched movement of the cylinder hole and the piston, the diameter of each section of the cylinder hole can be changed due to heating deformation, and a certain taper is generated, so that the influence of the taper generated by heating on the movement of the piston is avoided, the service life and the use efficiency of the piston are reduced, and in the cylinder hole honing process, a certain taper can be firstly honed, so that the diameter of a part which is easy to deform during heating is small, and the diameter of a part which is difficult to deform is large. The cylinder hole is expanded at the position of a part which is easy to deform and generates high heat in the actual movement process, and the part with small diameter of the cylinder hole is enlarged, so that the cylinder hole keeps good cylindricity in the process of matching movement with the piston, and the service life and the efficacy of the piston are improved.
