Description
Technical field
The invention belongs to cutter and its manufacturing process areas, specifically, be related to a kind of ultra-thin alloy cutter of overlength and its
Manufacturing method.
Background technology
Alloy cutter is widely used in cutting for wooden, plastics and other items；Such as a kind of photo frame cutter, shape are that length is flat
Shape, length are differed from 500mm to 2500mm, and thickness is generally in 10mm or less；Common alloy cutter length is in 2000mm hereinafter, thickness
Degree is in 10mm or more, and processing and manufacturing difficulty is little, and the prior art disclosure satisfy that the performance requirement of the alloy cutter；But by
Requirement is cut in handicraft product, cutting precision is higher, and the length and thickness requirement to alloy cutter are also increasingly harsher, and length exists
2000mm or more, thickness in the ultra-thin alloy cutter of 10mm overlength below using more and more, however, the manufacture work of this cutter
Skill still cannot then meet its performance requirement using traditional processing method, low so as to cause precision is cut, and service life is low etc.
Varied problem.
Analysis conventional technique process the ultra-thin alloy cutter problem of above-mentioned overlength it is found that long flat alloy cutter essence
Degree is embodied in its whole straightness, and it is 0.03-0.05mm that traditional handicraft, which processes the attainable straightness of common alloy cutter institute,
And the ultra-thin attainable straightness of alloy cutter institute of overlength that traditional handicraft is processed has dropped an order of magnitude, is only capable of maintaining
0.1mm or so, this obviously greatly reduces the precision quality of alloy cutter；In addition, common alloy cutter is direct using ratio-frequency welding
Alloy cutter head and cutter hub are welded, in conversion to the ultra-thin alloy cutter of above-mentioned overlength, cause alloy cutter head not prison welding solid, rear
It is easy to be partially disengaged when continuous straightening technique, seriously affects the quality and service life of alloy blade.
