A tool system for ultra-high-speed cutting of CNC machine tools

Abstract

The invention discloses a cutter system for super-speed cutting of a numerically-controlled machine tool. The system comprises a main shaft, a housing, a locking sleeve and a cutter. The system is characterized in that the upper end of the main shaft is connected with the numerically-controlled machine tool; an input bearing is mounted at the lower end of the main shaft and positioned on the housing; the main shaft is connected with a rotating frame, and a crankshaft is mounted on the rotating frame; an epicycloidal wheel and a cycloidal wheel bearing are mounted in the middle part of the crankshaft, and a planet gear which is engaged with a sun gear is mounted at the lower end of the crankshaft; an output bearing is mounted on the sun gear and positioned on the housing; the sun gear is connected with the upper end of the locking sleeve, and the lower end of the locking sleeve is connected with the cutter. The system has the beneficial effects that the cutting rotation speed is extremely high during the processing of aviation and precision optical devices; the processing effect is good; the processing accuracy is high; extremely high surface roughness can be obtained; the actual engineering requirement of high-speed cutting can be met; the technological gaps can be filled; and moreover, the social benefit and the economic benefit are high.

Description

technical field [0001] The invention relates to the field of advanced manufacturing technology, in particular to a tool system for ultra-high-speed cutting of a numerical control machine tool. Background technique [0002] Ultra-high-speed cutting technology is generally considered to be an advanced manufacturing technology that cuts parts at a speed 10 times higher than conventional ones. The research results show that when the cutting speed is increased by 10 times and the feed rate is increased by 20 times, the cutting mechanism has undergone a fundamental change, and the cutting effect has also been greatly improved. The metal removal rate per unit power has increased by 30%-40%, and the cutting force has decreased. 30%, the cutting life of the tool has increased by 70%, the cutting heat left in the workpiece has been greatly reduced, the cutting vibration has almost disappeared, and the cutting process has undergone a substantial leap. A series of problems that have be...

Problems solved by technology

At present, the main problem restricting the development of ultra-high-speed cutting technology is that the rotational speed of the machine tool spindle and the moving speed of the feed system are relatively low, which cannot meet the speed requirements of ultra-high-speed cutting.

[0004] In order to solve technical bottlenecks such as low spindle speed, poor cutting effect, low processing efficiency, and low manufacturing precision in the existing prior art CNC machine tools, the present invention proposes a tool system and implementation method for ultra-high-speed cutting of CNC machine tools. Fast, high cutting efficiency, good parts processing effect, high surface precision, beautiful appearance, can not only meet the actual engineering needs of ultra-high-speed precision machining, fill the gaps in related technologies, but also generate greater social and economic benefits
