BT-60 Manual Cupping testing machine Cupping testing machine, designed according to GB/T 4156-2007, is used to evaluate the resistance of metal materials to the anti-cracking or anti-separation of metal substrates after being subjected to the indentation test under the standard test method. Usage Cupping testing machine, designed according to GB/T 4156-2007, is used to evaluate the resistance of metal materials to the anti-cracking or anti-separation of metal substrates after being subjected to the indentation test under the standard test method, Two-way composite cylinder for measuring metal stretchability. It uses a sphere with a diameter of 20 mm. The steel ball is topped at a certain speed, and the surface of the test plate is observed through the observation hole. Stop immediately when the test plate is deformed and the first crack is observed.
