Multi-directional Bench Type Magnetic Particle Testing Machine
Magnetic Crack Detector Machine for Steel Bars
This wet, horizontal, bench-type unidirectional machine generates circular magnetization designed for inspecting both bright and black rolled steel round bars. Circular magnetization is achieved by clamping the bar directly between the headstock and tailstock, passing current through it. The machine is proficient in detecting longitudinal cracks exclusively. The headshot current can be switched between HWDC and AC for detecting subsurface and surface cracks. The machine operates semi-automatically, with all operations—loading, spraying, magnetization, demagnetization, and unloading—being automatic. The only manual operation is the inspection.
- The machine is equipped with nylon rollers designed for positioning and rotating the bar during the inspection process.
- The machine features an adjustable magnetization time of up to 2.0 seconds, enabling the thorough development of indications.
- Available in a range of part lengths and diameter sizes.
- The machine comes equipped with a darkroom frame, hood, and curtains, facilitating inspections with fluorescent inks.
