Marking chamfer and taper is a routine work in Mechanical drawing.
在机械制图中，通常需要进行大量的倒角和锥度的标注工作。
2
The reclaiming taper of the utility model is unlikely to be deformed and damaged under the work condition of high temperature in the production process of cement.
本实用新型在水泥生产过程中高温工作条件下，其出料锥不易 变形损坏。
3
Consequently avoid repeat operation when we wind taper cylinder, decrease labor power and increase work efficiency.
