Hi,
I am looking for someone to machine on a CNC mill some steel "dogbone" tensile samples for uniaxial testing on an Instron.
I would provide rough stock in the form of steel rectangular bars that will be oversized by up to 3 mm in each dimension. Each of those bars needs to be CNC machined to the ASTM E8 size of 100 mm long by 4-6 mm thick with grips of 10 mm width and narrowed gage portion width of 6+/-0.1 mm width.
See sub-size specimen (0.25 in wide) in the table of Flat test specimen dimensions: https://en.wikipedia.org/wiki/Tensile_testing
I will have sets of 20 samples per week, mostly steels with occasional nickel-based or titanium alloys. If you are interested in this job or have used a service you'd recommend, please let me know.
Thanks!
