What Is a Machine Taper?
Taper refers to the ratio of the diameter of the bottom surface of the cone to the height of the cone. The taper plug gauge is mainly used to check the large diameter, taper and contact rate of the product, which is a special comprehensive inspection tool. Taper gauges can be divided into two types: size gauges and painted gauges. Because the design and testing of the color taper plug gauge are relatively simple, it is widely used in workpiece measurement.

- 6 1: 19.180 63.348
- The relationship between the taper C and the cone angle is:
- C = 2Xtg ( / 2) [2]
