It is the cutter blank by the cutter blank forged relative to sheet material, its knife middle part is recessed cambered surface, cross section is tapered, thickness is inconsistent,
Mechanization polishing can not be carried out with levigator.
At present, grinding technique for forging non-corrodible steel knife is all artificial grinding, and emery wheel is slightly polished first, and people holds cutter blank in rotation
Emery wheel on slowly grind, then with diamond dust to cutter blank carry out fine grinding it is repeated multiple times, last polishing cloth is polished plus antiscuffing paste,
Technique is cumbersome, and whole forging non-corrodible steel cutter blank is during manual polishing, and the stage is roughly ground due to being manual polishing in emery wheel
There is no water-spraying control, the bad control of cutter hub temperature after the temperature of cutter blank is due to emery wheel friction more than 400 degree, will result in
It is relatively more that the hardness of cutter blank declines scrap.
In addition, traditional cutter blank fine-processing technique polishing is ground by one side, flat stone mill, the surface of knife before mill, after pass through
Rubber wheel is polished, and specular light is thrown in another polishing.Mainly the knife back turns into a gradient with the edge of a knife, is easy to polishing.Now
Our cutter blank be forge cannot use this method.The requirement back of the body thickness 6mm-10mm of knife, when the knife back is to blade direction 25mm
Its thickness is 1.5mm, is being 1.0mm to blade direction 2.0mm its thickness, behind 0.8mm to sword 0.03mm.It follows that knife
Carry on the back blade band cambered, structure can be destroyed with traditional processing polishing.
