Within the day, our engineers were operating the machine and milling our square stock specimens. The unit has proven to be an easy round tensile sample preparation solution. As a result, we had ordered 9 additional machines for various locations across the country. This user friendly round tensile sample preparation machine is one of a kind.

1.1 Working principle of conventional milling machining. In milling operation metal is removed by a rotating multipoint cutter which is fitted on the arbor of the milling machine and fully operated by human as Fig. 1. [] had determined a technical concept and machining possibilities for milling of micro structures by using a fast tool servo (FTS) for high precision product.

Milling: Manual milling machines use handwheels and lead screws to articulate a cutting tool onto a workpiece. In a CNC mill, the CNC moves high accuracy ball screws to the exact coordinates programmed instead. Milling CNC machines come in a wide array of sizes and types and can run on multiple axes.
