Sine Center: It measures the angles of the conical workpieces that have male and female parts. This type of sine bar can't calculate an angle of more than 45 degrees. Sine Table: This wide and large sine bar locks itself after positioning. That's why it can hold the workpiece during the whole measuring process. Compound Sine Table: This type of sine bar is used for large components, which you can’t measure with the simple bar. In the compound sine table, two sine tables are installed at the right angle and can be rotated as per measurement requirements.
