GBW-60 Computer Control Cupping (Erichsen) testing machine
Main Applications:
The cupping testing machine is used to test extend and stretch capacity of metal thin plate and band. It is the only instrument to test the metals plastic deformation.
The machine accords with GB4156-84. Also it can be used to test non-ferrous metals anisotropic character if adding impact cup mould. The machine adopts closed loop control and constant speed loading, so the test procedure can realize variable speed.
This machine is servo closed-loop control and constant rate loading. It adopts load sensor and high precision photoelectric encoder, electric control mechanical loading, high control and test precision.
Main Technical Specifications:
1. Plate thickness: 0.05 ~ 2mm can be customized (high-precision load sensor, which can be used for ultra-thin plate test)
2. Plate width: 90-100mm;
3. Punch stroke: 40mm;
4. Clamping piston stroke: 40mm.
