Problems solved by technology

[0003] After the equipment has been used for a period of time, the accuracy guarantee will decline. The technical problem to be solved by the present invention is to provide a processing technology that eliminates the time difference of the milling plane when the equipment has a slight positioning error. When the equipment accuracy cannot be fully satisfied , through process compensation to eliminate the level difference between the knife and ensure the smoothness and brightness of the large plane, the hand feel has no level difference and the appearance meets the requirements

Abstract

The invention discloses a machining technology capable of eliminating a segment gap during plane milling under the condition of the presence of an equipment positioning error. The technology comprisesthe following steps that a) a high-precision four-axis linkage full-closed-loop horizontal machining center is selected for use, and a cutterhead with the diameter phi being 200 and blades are adopted; b) a workpiece mounting table is mounted and leveled; c) rough milling is performed; d) semi-finish milling is performed; e) finish milling is performed; and f) sleeking is performed. Compared withthe prior art, the machining technology can be used for guaranteeing that a large plane is smooth and bright, free of segment gap hand feel and capable of meeting requirements for the appearance.

Description

【Technical field】 [0001] The invention relates to the technical field of mechanical processing, in particular to a processing technology for eliminating the time difference of milling planes when the equipment has a positioning error. 【Background technique】 [0002] The processing of nuclear power equipment, wind power equipment, all-electric precision injection molding machines, and high-speed precision punch parts requires extremely high precision on large planes. The gap between the knife and the knife. Since the material is nodular cast iron QT400-18, it has been unable to completely eliminate the slight step difference between the blades on the large plane, which affects the horizontal accuracy of the equipment when it is installed and fixed. The requirements for visual appearance are also increasing. It is required that the surface should be smooth, uniform in color and without mirror effect after processing, but the knife pattern should be processed neatly and withou...
