许多零件、模胎经机械加工后,还要进行表面打磨、抛光——大多先用手工锉修或刮削,然后再用砂布抛光。为了解决工效低、劳动强度大的问题,我们研制了一种高速快装的风动打磨工具。经过试用与改进,现已普遍用于生产。提高工效1～5倍,尤其在大面积抛光中效果更为明显,抛光后的表面光洁度可达▽6～▽7。 Many parts, mold tire after machining, but also for surface grinding, polishing - most of the first with manual file repair or scraping, and then polished with emery cloth. In order to solve the problem of low efficiency, labor-intensive, we developed a high-speed quick-loading pneumatic grinding tools. After trial and improvement, is now widely used in production. Improve work efficiency 1 ~ 5 times, especially in large area polishing effect is more obvious, polished surface finish up ▽ 6 ~ ▽ 7.
