Description
Technical field
The present invention relates to field of machining, relate in particular to slabbing process tool and processing method.
Background technology
At present, generally all there is the problem that working (machining) efficiency is low, processing cost is high in domestic Mechanical Manufacturing Enterprises in the man-hour that adds of carrying out heavy parts such as engine housing, and these workpieces to be machined often have the characteristics that working (finishing) area is big, chipping allowance is big.For the situation of this big surplus plane processing, use common face milling cutters usually, adopt the processing mode of layered milling to process, also can adopt the processing mode of a milling of big cutting-in milling cutter to process sometimes.But all there is certain defective in above-mentioned two kinds of processing technologys: if 1 employing layered milling processing; Owing to need the surplus of removal big; Especially for the bigger plane in enormous quantities processing of area, layered milling processing will influence process velocity greatly, cause working (machining) efficiency low; If 2 adopt a milling of big cutting-in milling cutter to put in place; Then very high to the machine power requirement, and the very big cutting force that in working angles, will produce, this not only can cause machine vibration; Also can influence the life-span of cutter, generally not adopt this processing technology in the therefore actual processing; 3, owing to be the removal of big surplus, long-time cutting all will blade cause very lossy with big cutting force cutting, and this has increased processing cost to a certain extent.
Summary of the invention
The technical problem that the present invention will solve is the deficiency that overcomes prior art, and a kind of loss of blade, the big surplus unequal-diameter double-layer milling cutter that reduces machine power loss, raising working (machining) efficiency, minimizing waste of material and big surplus slabbing method of reducing is provided.
