The elastic limit also referred to as the point at which the tensile force induces permanent deformation, will eventually be reached by any material that is tested. The force required to push material to this limit is known as its yield strength. Because highly brittle materials like glass or ceramics would break under stress before they display any flexibility, they do not have a clearly defined yield point. Lower yield strengths of more fragile metals make them less useful in many industries. A metal is essentially useless if it is engineered to be so fragile that it is impossible to know where its yield point is.

Only small amounts of heat are delivered to the material when utilizing a CNC machine. Additionally, throughout the cutting operation, machine coolant is applied to the working area of the specimen. Because burns are no longer a concern, using CNC mills with any material whose properties may be altered by heat is particularly advantageous. Several metals are included in this, along with plastics, acrylics, composites, and laminates.

The repeat position accuracy of NextGen’s TensileTurn CNC – Round Tensile Sample Preparation Machine is X:±0.02mm,Z:±0.02mm.
