Gantry type rough and finish composite five-axis precision machine tool and processing method thereof

Abstract

The invention relates to a gantry type rough and finish composite five-axis precision machine tool and a processing method thereof and belongs to the field of precision machine tools. A rack is horizontally arranged; an X-Y feeding component is installed on the rack; a two-axis turntable component is installed on the X-Y feeding component through a Y-direction sliding plate; a sharp knife processing component and a fast removing component are installed on the two sides of a middle cross beam in a gantry shape through a guide rail seat and a vertical plate respectively; and a detector is installed on a sliding plate of the sharp knife processing component. The gantry type rough and finish composite five-axis precision machine tool has the characteristics of high processing efficiency and processing precision and can meet the processing precision requirement for rough milling semi-finish milling; by adopting a five-axis linkage processing method, multi-angle flexible processing can be realized, and the processing process from a blank to a finished product can be completed at one time; as a two-axis turntable is compact in structure, high in rotation precision and good in rapid response characteristic, the gantry type rough and finish composite five-axis precision machine tool has better use reliability; and with three-direction rotation and one sharp knife feeding system moving in a longitudinal feeding direction, multi-dimensional adjustment of a milling cutter processing angle is realized.

Description

technical field [0001] The invention belongs to the field of precision machine tools, in particular to a gantry type rough-fine compound five-axis precision machine tool and a processing method. Background technique [0002] Since the beginning of the 21st century, some optical components with non-rotating, asymmetric complex surfaces or microstructures have been used more and more in military and civilian fields with high automation requirements and even in scientific research fields.
