Model: NL-LLSY-5T
The problem
Change the raw material batch and tensile strength or elongation can quietly drop; without a curve nobody can tell whether it is the material or the process. A hand-held force gauge gives a single peak value, fracture position, yield point and elongation are written down by hand, and batches cannot be compared. When a customer audit asks for raw curves and statistics, there is nothing to show.
Capability
The machine is built to class 0.5 accuracy with a 50kN (5 tonne) capacity selectable within the range: force measurement from 0.2% to 100%FS with +/-0.5% accuracy, force resolution 1/300000 and stepless auto-ranging across the whole span, so small crimp-pull values and heavy structural samples are both measured properly on one frame. Displacement indication error is within +/-0.5% with 0.04mm resolution; speed is adjustable from 0.01 to 1000mm/min within +/-0.5%. A Delta servo motor and servo controller drive an NMRV050 precision hollow cast-aluminium reducer through twin precision ball screws and 50mm guide columns (induction hardened and hard-chrome plated, above HRC60), with NSK ball bearings and a high-strength timing belt. Test stroke is 1000mm without fixtures and clear column spacing is 410mm. Tension, compression, three- and four-point bending, shear, tear, peel, adhesion and folding tests can all be configured. The Windows-based software offers Chinese/English interface, function navigation, graphic test flows and break-point stop; test projects are created by technicians and simply recalled by operators. Force-displacement curves are plotted live with multi-curve overlay analysis, statistical calculation (mean, standard deviation, coefficient of variation), user-defined data items and formulas, and Word/Excel report output. Protection covers mechanical limit switches, E-stop braking, over-current, over/under voltage, leakage, software over-load limits and break-point stop; the main frame and control cabinet are separate, finished with DuPont powder coating cured at 200degC.
