A team from TE Connectivity of Norwood, Massachusetts, recently visited Bel Air Finishing Supply’s Process Technology Center in Kingston, Rhode Island, to get help in developing a very specific surface finish for a new automotive connector needed by a major automaker.
TE Connectivity designs and manufactures connectivity and sensor products for a variety of applications. Bel Air is a manufacturer and supplier of mass finishing technology. Bel Air President Steve Alviti says the team tested two or three of 23 different processing technologies, and four of about 5,000 varieties of honing media to reach a satisfactory finishing solution for the part, which was made on a Swiss-type CNC machine.
“The goal was to match the stringent finishing requirements of the end user and marry that with the manufacturing culture of TE’s facility,” Alviti says.
The team also carried out extensive testing with the aid of Bel Air’s non-contact white light interferometry measuring system to ensure that the results met the high standards.
“The final process was completely repeatable, and required very little operator effort,” Alviti says.

Surface finish types for commercially supplied stainless steel sheet are detailed in various standards. ASTM A480-12 and EN10088-2 are two; BS 1449-2 (1983) is still available, although no longer active. These standards are very similar in that they define eight grades of surface finish for stainless steel. Grade 7 is “buff polished,” while the highest polish—the so-called mirror polish—is designated Grade 8
It has been shown that the inexpensive chemically accelerated vibratory surface finishing (CAVSF) process can reduce the average surface roughness.
