Finishing tools and calculators
Working tools for the problems that actually cost money in finishing: threads that will not gauge after plating, media that jams in cross-holes. Free, no sign-up, and the arithmetic is shown so you can check it.
MFI has been finishing parts in Cincinnati since 1992. These are the calculations we run for customers on the phone, built so you can run them yourself before you release a drawing or send an RFQ. Where a number comes from a published standard we cite the clause. Where it comes from a formula we show the formula. Where it is trade practice rather than a standard, we say so.
