Sine Centre:- Defination, Diagram, Working Principle, Uses of Sine Centre

Sine Centre:-

• This is a sine bar with block holding centre which can be adjusted and rigidly clamped in any position. • Generally used for inspection of conical objects between centre. • These are used up to inclination of 60 degree. • Principle used here is same as of the sine bar. •

• It is a convenient and accurate design for heavier components. • In that one roller of the sine bar is hinged on its datum surface. • So it can be swung at any angle from zero degree to ninety degree about its hinged end. • Very useful in measuring angles of taper plug gauge.
