Novel plunge type inner/outer curved surface cutting/grinding/polishing process and system

Abstract

Disclosed is plunge type inner/outer curved surface cutting/grinding/polishing process, which comprises a hard pressure head, a cutting layer and a workpiece. The appearance of the hard pressure head can be optionally selected according to needs, the shape of an end of the hard pressure head is processed and shaped according to technical process requirements on an inner/outer curved surface of the workpiece, and the hard pressure head can be made of metal and nonmetal materials while the rigidity, the abrasion resistance and the size of the pressure head are determined according to conditions of machines and equipment. The cutting layer is made of composite cutting materials, is high in strength, not easy to be broken and fine in coincidence property, is heat-resistant, and can realize cutting/grinding/polishing effects. The workpiece is a processed part. By the aid of plunge type cutting/grinding/polishing of the forming hard pressure head, deviation of shapes and positions of inner/outer curved surfaces caused by conventional grinding wheels and abrasive stones can be avoided, the shortcoming of poor precision caused in a previous production procedure can be overcome, and reject ratio of products can be greatly reduced. The plunge type cutting/grinding/polishing technology has the advantages that firstly, the shape of the same pressure head can keep basically consistent regardless of the amount of curved surfaces of workpieces processed by the aid of the hard pressure head, and secondly, inner/outer curved surfaces in any shapes can be processed only by means of changing the shape of the pressure head, and application range of the plunge type inner/outer curved surface cutting/grinding/polishing process is wide.

Description

technical field [0001] The invention relates to a processing technology for inner / outer curved surface workpieces, in particular to a new technology and system for plunge-cut grinding / grinding / polishing processing inner / outer curved surfaces. Background technique [0002] At present, the surface processing of curved workpieces is mainly realized by grinding with grinding wheels and oil stones by various machines. Due to the uneven surface of curved surface workpieces, traditional grinding and superfinishing methods often use manual operations or grinding wheels and oil stones, which have disadvantages such as uneven force on the surface of the workpiece, time-consuming and labor-intensive grinding, and uneven arcs on the curved surface. There are disadvantages such as poor fine quality, low production efficiency, and high labor intensity. [0003] Taking the workpiece bearing as an example, the current ultra-finishing process of deep groove ball bearing raceway is a grindi...
