Friction Coefficient Testing Machine
NK-M500E Friction coefficient testing machine
Product introduction
NK-M500E high-strength bolt comprehensive detector mainly detects high-strength bolt connection pairs. It can detect the axial force, torque, torque coefficient, total friction coefficient, thread friction coefficient, and bearing surface friction coefficient of high-strength bolt connection pairs. The equipment is driven by a servo motor to automatically load a cycloidal pinwheel reducer, with a linear guide, a full Chinese operation interface, and a computer to control the automatic tightening, loosening and resetting of high-strength bolts. The operation process is intelligently prompted, and the operation is convenient and fast. When the axial force reaches the standard setting value, the detector will automatically record the test data, and automatically calculate the average axial force, average torque, average torque coefficient, average total friction coefficient, average thread friction coefficient, and average bearing surface friction coefficient of the sample through the computer, and can automatically calculate the standard deviation and coefficient of variation. At the same time, it can also display the axial force curve, torque curve, etc. in real time, and has the functions of parameter setting, calibration, data report printout and query.
Application:
This equipment is currently the most popular high-strength bolt testing equipment with low investment and high return in scientific research institutions such as wind power bolt manufacturers, engineering quality inspection agencies, steel structure construction units, engineering supervision agencies, high-speed railways, bridge power, and universities and colleges.
