西德 Leitz 200型象点仪可对线纹,端面和内孔零件进行精密测试。在长期使用以后,该仪器不免会出现一些机械故障。笔者现将调修中的一些体会介绍给大家,供参考。1.快速调整台架时,电磁抖动声的产生和排除如图所示,如果永久磁铁与滑板在通电脱开后间隙过大,将影响台架与底座的锁紧程度,若间隙过小,由于磁场的作用,便会产生较大的电磁抖动声。调修中,将仪器右边的读
The West German Leitz 200 Pixel Tester accurately tests line, face and bore components. After long-term use, the instrument will inevitably be some mechanical failure. I now introduce some of the experience in the repair for everyone for reference. 1. Quickly adjust the gantry, the generation and removal of electromagnetic jitter sound as shown, if the gap between the permanent magnet and the skateboard is too large after the power is off, will affect the degree of locking the gantry and the base, if the gap is too small, Due to the magnetic field, it will produce a large electromagnetic jitter sound. During the repair, read the instrument on the right
