"Tolerance fit" showcase

Tolerance with teaching display case


"Tolerance fit" is an important technical foundation standard with a wide range of influences. It is a necessary condition for achieving zero and component interchange. Learning this course well is of great significance for mastering technology, guiding production and completing the work of this employee.
The model is made of imported organic board and hard polychloride. The surface panel is directly made on the chart with diagrams and text descriptions. The process is beautiful. Using this display cabinet can improve the teaching effect and save hours. It is a set of modern practical machinery teaching equipment. This set of display cabinets are divided into six cabinets, which are available in the first and second generations. ( Teaching Equipment | Teaching Instruments )
