No. 4 finishing on laser cut 20-mil flat bar

Hi there,

How are you all? hope well. I am just a welder fabricator of stainless steel jobbing. I mainly do balustrades so in my job line I get so many flat bar and angel iron to give no 4 finish. I use 60grit sanding disk followed by 80 and 120 and then finally I use scotch brite belt. It takes a a bit long time to finish one piece. I am just wondering how can I speed up my polishing time coz my boss thinks that I am not doing right way, thats why I am taking so long to finish my job. Please advise me what can I do to get it done fast.

Thanks and take care.

Regards,

If you are starting out with 60 grit, the metal you are working with must be pretty rough. Succeeding step are typical; therefore, the only way to improve time is to try to create a fixed pass through wheel system (semi-automatic) or start out with a better surface finish bar metal. Lastly, maybe ask your boss to do it himself.
