The treatment of balata whorl

The only head of 5 ～ 1280mm and bull balata whorl, its quality all accords with a requirement. Because the hardness of balata is very low, stretch model quantity has 2 only.

35N, be equivalent to the 1/85000 of carbolic steel, below the action of outside force, be out of shape extremely easily, when cutting very difficult. Especially cutting machines whorl of a few abnormity, more difficult. To solve the treatment of balata whorl, a wheelhead that can adjust helix angle arbitrarily is installed on lathe, or in whorl precision requirement not high case falls, wheelhead of usable also pneumatic is replaced. Emery wheel uses Ø80mm of diametical Ø60mm ～ , the white corundum emery wheel of the 60# ～ 100# that granuality is. After emery wheel is installed, it is good nap of emery wheel appearance to use diamond pen, the law that the appearance of emery wheel is whorl to sectional appearance. Whorl lead is small, lathe nameplate has, can pull motor-car bed handle to obtain directly. Go up when lathe nameplate, must calculate those who give place to need to hang annulus. Can check manual commonly, also can use calculative method, beg what go out and make place need to hang annulus. When common thread lead is more than 300mm, must reduce main shaft rotate speed, lest because main shaft rotate speed is high and quality of influence whorl grinding, also make operate the part of insecurity or attaint feed box at the same time. The method of decelerate has: Change advocate, passive leather belt annulus diameter; Reducer casing increases outside lathe. Separately method, with the method of car bull whorl. Grinding balata whorl is used on lathe, it is the treatment craft of a kind of efficient, Gao Zhijin, use the method of grinding early or late, treatment lead is 1.
