The invention provides a method for
machining a narrow groove in a planing mode by a
numerical control boring and milling
machine. The method comprises the steps of 1, clamping a work-piece and enabling the
machining face to be parallel with a main shaft of the
numerical control boring and milling
machine and the length direction of the narrow groove to be parallel with the direction of the main shaft; 2, clamping and correcting a cutter and enabling the
machining direction of the boring cutter to be parallel with the length direction of the narrow groove and the feed direction to be parallel with the thickness direction of the narrow groove; 3, fixing the main shaft; 4, carrying out
programming machining, wherein a
numerical control shaft parallel with the length direction of the narrow groove to be machined does the main
cutting motion, a numerical control shaft parallel with the
depth direction of the narrow groove to be machined does the feed motion and then a program is started for machining. Through the steps, the numerical control boring and milling
machine can be used for machining the narrow groove in the planing mode. By adopting the numerical control boring and milling machine for machining the narrow groove, the machining efficiency is improved, the machining quality is guaranteed, the operation is simple, convenient and practicable, and the width of the groove is easy to control. By adopting the method, the efficiency of machining the narrow groove is 2-5 times that of machining the narrow groove by an
end mill, and the economic benefit of machining the groove with the width
ranging from 2 mm to 4 mm is the most remarkable.
