Raise the method of precision of angle of machine tool roll

5 ° , and often can encounter the work with angle precision higher demand in actual production. Be like: XMilling machine of 53K vertical lifting platform establishs milling head, the scale division value of original dial is every case 0.

5 ° (show) 1 times like the graph, want to machine angle precision to ask expensive work assures very hard. The author is made a bit to milling machine in real work improve, got very good use result. Are its main does the method introduce following: ? ? (1) writtens guarantee composition of a picture shows the case that makes dial spread out to use cursor principle 2 times basically, advocate feet is the original dial on milling machine dial, its engrave line interval to be 30 ′ (0.

5 ° ) , stand; we change our costume or dress in position of line of milling machine former null one secondary scale, take advocate on feet 29 case (namely 14.

5 ° ) length cent is 30 case, criterion the reticle scale division value of secondary scale is 29/30 × ′ of 30 ′ =29. Principle of reticle of graph 2 (2) advocate the difference of the reticle scale division value of feet reticle scale division value and secondary scale is 30 ′ - ′ of 29 ′ =1, this one margin is the reading value of this index plate namely. When secondary scale 0 lines and advocate 0 lines check rule neat when, the first reticle of secondary scale and advocate the first reticle of feet differs 1 ′ , the 2nd differs 2 ′ thirtieth differ 30 ′ (namely 0.

5 ° ) . Rotate right when secondary scale when 1 ′ , criterion secondary scale the first reticle after 0 lines and advocate some reticle of feet is become to neat; secondary scale rotates right when 2 ′ , criterion secondary scale the 2nd reticle after 0 lines and advocate some reticle of feet is right neat ordinal analogize. (3) reading method: of the first pace? Does facial gum carry Bi Lang on the back well is Gu of Qiao of Lie of an insect destructive of the roots of seedlings Piao of mu of benevolence  saddle benevolence  ? : of the 2nd pace? Qiao of leg of smile of flood of  of mother of summer of Gu of swiftly hammer back knocks at? of cloud of be favored with of which morning flood to numerate directly fractional portion. : of the 3rd pace? Amine of benevolence  of Piao of  of  benevolence  pledges? of Su of  branny obstruct reachs the angle that establishs milling head roll is counted namely. The graph is shown 3 times turn to establish milling head 46 ′ of 2 ° . Graph 3 courses carry out a proof, this kind of method is simple, swift, rose to machine precision greatly, this method still can be used at similar orgnaization, if the small slide of general accuracy machine tool is rotational,wait.
