20090106995 | PLANENESS TESTING APPARATUS - An exemplary apparatus for testing planeness of a workpiece is provided. The apparatus includes a platform for supporting the workpiece thereon, a bracket vertically mounted to the platform, and a testing system mounted to the bracket for testing the workpiece. The testing system includes a testing member, a test dial indicator having a sliding pole, and a fine-tuning member for controlling the movement of the testing member. One end of the testing member is connected to the sliding pole. When testing, the fine-tuning member drives the testing member to move toward the workpiece, until the testing member contacts the workpiece. The sliding pole extends together with the testing member. A value is shown by the test dial indicator that indicates the moving distance of the testing member. A distortion value of the workpiece can be obtained according to the value. | 04-30-2009 |
