Ford Typewriter Ford Typewriter The Ford typewriter was an early prototype typewriter introduced in 1895 by Eugene A. Ford, who later became chief development engineer at IBM (no relation to Henry Ford who founded the Ford Motor Company). It was a commercial failure and only a few were manufactured. Unlike many competing typewriters of this time, it was a forward-striking machine, meaning the hammer struck forward against the paper which was held against the platen roller, instead of up from underneath. This allowed the typist to see the text as it was typed, which was not possible in most other typewriters of
Roller burnishing Roller burnishing Roller burnishing is a surface finishing technique where hardened rollers cold work surface imperfections to reduce surface roughness. Roller burnishing differs from abrasive surface finishing techniques in that material is displaced rather than removed. The tooling typically consists of a hardened sphere or cylindrical roller. The tooling is pressed into the surface of the part while it is rotated (in some applications, the tools are rotated instead of the part). The burnishing tool rolls against the surface of the part at a constant speed, producing a very consistent finish across the part. A surface finish of less than
