Taper turning and taper measurement methods

The taper turning methods is usually: turn the direction of the feeding direction of the small slide, offset tailstock method, profile modeling method and the use of CNC Turning lathe to Machining taper surface. No matter what method is used to process the taper surface, the correctness of the taper by turning is the primary problem. For the processing of the test taper is correct or not, in addition to the use of protractor, there are many measurement methods. If you need accurate measurement results, you can use the dial indicator method for taper measurement. The specific steps are as follows: After a taper section has been cut (the length of the taper surface is shorter than the length required for turning to the drawing) , fit a magnetic watch seat in the free position of the tool holder or the carriage, install a dial gauge or a dial indicator on the magnetic table, make the head of the meter contact the end of the turning taper surface horizontally vertically, remember the pointer and scale, and then the bed saddle moves toward the large end of the conical surface for a distance L, generally to L = 10mm is appropriate, make the dial indicator moves from the little end to the large end, if the difference between the scale of the head pointer at this time and the scale of the previous dial pointer conforms the value of the taper, explaining that the cone of the taper surface is correct, otherwise it is necessary to adjust the taper. The method avoids the possibility that the taper of the taper surface does not conform to the drawing. The specific adjustment method varies according to the turning requirements.
