Milling and polishing integrated equipment and machining method

Abstract

The invention provides milling and polishing integrated equipment and a machining method. The milling and polishing integrated equipment comprises a lathe bed, a five-axis linkage system and a tool selecting mechanism, the five-axis linkage system and the tool selecting mechanism are installed on the lathe bed, the five-axis linkage system comprises a tool displacement mechanism used for adjusting the space pose of a tool and a workpiece pose adjusting mechanism used for adjusting the space pose of a to-be-trimmed workpiece, the tool selecting mechanism comprises a milling cutter magazine, a polishing wheel magazine and a tool changer which are mounted on the lathe bed, the tool changer is used for tool replacement, the tool displacement mechanism comprises a spindle box, a spindle for mounting the tool is mounted in the spindle box, and a plurality of holes for spraying cutting fluid and polishing fluid are further formed in the spindle box. According to the milling and polishing integrated equipment and the machining method, during machining, the workpiece only needs to be clamped once, a milling cutter is replaced with a polishing wheel through the cutter changer after milling machining is completed under the same set of machining parameters, chemical mechanical polishing is conducted in combination with the polishing liquid, secondary clamping is avoided in the polishing process, the milling process and the polishing process have the same cutter feeding path, and the form and position precision of the polished part can be obviously improved.

Description

technical field

[0001] The invention relates to the technical field of mechanical processing equipment, in particular to a milling-polishing integrated equipment and a processing method. Background technique

[0002] High-performance parts with complex curved surfaces are usually processed by five-axis simultaneous milling. After processing, the surface roughness Ra≥3.2μm, while high-performance parts require surface roughness Ra≤0.8μm. Service requirements for high-performance parts with complex surfaces. High-performance parts with complex curved surfaces usually use manual grinding and polishing to meet the surface roughness requirements, and high-performance parts with complex curved surfaces in some fields also use manual grinding and polishing technology abroad. However, manual grinding and polishing is labor-intensive, low in efficiency, and unstable in quality, and it is easy for operators to inhale dust and cause occupational diseases. Traditional mechanical grind...
