小口径不锈钢圆管内壁抛磨机的研制

Development on polishing machine of small diameter stainless steel tube wall

针对化工、制药、食品等行业用小口径不锈钢管内孔壁光亮度需求很高的问题,研制了一种可抛磨小口径不锈钢圆管内壁的抛磨机床。该机床可抛磨口径为6～24mm的不锈钢管内孔壁,抛磨后不但去除了氧化层,而且内壁粗糙度可由原来Ra1.2μm减小至Ra0.5μm以下,为电解抛光工序作好了必要的准备。

For the chemical, pharmaceutical, food and other industries with a small diameter stainless steel tube bore wall problem of the high brightness requirements, developed a polishing machine that can polish small diameter stainless steel tube wall. The polishing machine can be within the diameter of 6～24 mm hole wall stainless steel tube, after polishing not only removes the oxide layer, and wall roughness can be reduced to Ra0.5 μm from Ra1.2 μm, prepare for the electrolytic polishing process.
