烟枪底板零件的加工

随着异形件国产化工作的深入，本文对烟枪底板的加工进行了攻关。为了得到精度高、弯曲小、内应力小、稳定性和精度保持性都好的零件，针对烟枪底板的变形，本文从烟枪底板的原材料、结构以及类似零件的加工方面入手，细化了加工工艺，并增加多道时效处理工艺，有效地保证了烟枪底板的尺寸公差及形位精度，探索出了烟枪异形件国产化的部分加工工艺。

Machining the major parts of the garniture

With the work of the diversiform parts made in our country going on, we have made great efforts for machining the major parts of the Garniture. Aiming at the deformation of the major parts of the Garniture, we have analyzed the raw material, construction and the machining of the similar parts of the major parts of the Garniture. Around how to achieve the high precision, less bent and little inner stress, start out to machine the parts with good stability and precision, fining the technological process and increasing the multi-way ageing treatment, we effectively assure the dimension tolerance and the shape and position precision of the major parts of the Garniture.
