在光学冷加工的粗磨工序中,虽然各厂都有了金刚石铣磨机,但有些光学元件装夹困难,象棱镜、各种大小不同的平面一类的光学零件,部分厂还是手工操作,劳动强度大,而且要由技术高的工人进行手工加工。我厂在粗磨铣削加工中,设计和改革了一些专用特殊夹具,采用机械化铣磨,经生产使用说明,能提高加工精度和工效,减轻工人劳动强度,也充分发挥机床的作用,而且还扩大机床加工工艺范围。一、多能平面真空吸附夹具在铣磨平面工序中,我们采用纵向切入铣磨法进行铣磨。金刚石磨头下降到预定位置后,磨头只作旋转运动,纵向拖板向右运动,电磁台上的真空夹具(或棱镜夹具)吸附着工
In the optical cold roughing process, although the factory has a diamond milling machine, but some optical components difficult to install, such as prisms, a variety of different sizes of optical components of a class, some factories or manual operation, labor Strong, but also by skilled workers for manual processing. I plant in the rough grinding and milling, the design and reform of some special special fixture, the use of mechanized milling, the production instructions, can improve the machining accuracy and ergonomics, reduce labor intensity, but also give full play to the role of machine tools, but also to expand Machine tool processing range. First, the multi-energy plane vacuum adsorption fixture In the milling plane process, we use longitudinal cut milling method for milling. After the diamond grinding head descends to the predetermined position, the grinding head only makes the rotational movement, and the longitudinal sliding plate moves to the right, and the vacuum fixture (or prism fixture) on the electromagnetic platform absorbs the work
