Pressure polishing Pressure polishing mp87 (Materials) (OP) 25 Jul 16 21:06 Hi, Is there anyone familiar with this machining operation? I am struggling to find any information on the Internet, maybe it is known with another name but I am bit lost at the moment. Thanks for your help. RE: Pressure polishing metengr (Materials) 20 Aug 16 20:40 Is this processing step for metals? I tried a search of pressure polishing and found several articles only related to a method for re-shaping patch pipettes during fire polishing. RE: Pressure polishing mp87 (Materials) (OP) 22 Aug 16 16:12 Hi metengr, Thanks for spending some time on my question. This process is used for a connection to a shaft in contact with a bearing. I hope to receive first-hand information from the supplier, for the moment based on the few comments I was able to collect the process should involve a "stylus" that is pressed on the surface reducing both peaks and valleys and introducing compressive stresses. It seems a smart way to improve the surface quality but I would like to know more about its cost and limitations. RE: Pressure polishing Compositepro (Chemical) 22 Aug 16 18:27 I believe what you are describing is called "burnishing". https://en.wikipedia.org/wiki/Burnishing_(metal) RE: Pressure polishing mp87 (Materials) (OP) 22 Aug 16 19:38 Hi Compositepro, Thanks for addressing me in the right direction. Considering the limited hardness increase given by the measurements, my guess is low plasticity burnishing. Will dig into further.
