The core highlight of this portable metallographic polishing machine lies in its portable design, with a net weight of only 12kg and a handle design, which is easy to carry and transport. It supports dual power supply modes of DC 24V battery and AC 220V, meeting the needs of indoor and outdoor use. The built-in mini water tank can realize independent cooling without external water supply, which is suitable for on-site testing scenarios without water supply conditions. The equipment adopts a high-precision frequency conversion motor, with a rotational speed range of 300-1800rpm, which can meet the polishing needs of different materials. The manual pressure control device allows operators to adjust the pressure according to the sample state, ensuring the quality of sample preparation. It is also equipped with a detachable base, which can be fixed on the workbench or used directly on site.

The polishing disc diameter is 150mm, the rotational speed adjustment range is 300-1800rpm stepless adjustable, the rated power is 0.55kW, the power supply specification is DC 24V built-in battery or AC 220V 50/60Hz, the net weight of the whole machine is 12kg, the overall dimensions are 450mm (length) × 350mm (width) × 600mm (height), the built-in mini water tank capacity is 2L, the applicable sample diameter range is φ10mm to φ30mm, the pressing force range is 0-30N adjustable, the operation control adopts manual knob speed regulation and pressure adjustment, the noise level is ≤68dB(A), and it is standard equipped with a detachable base and dust cover.

It is mainly applicable to on-site failure analysis of mechanical equipment maintenance sites, outdoor material testing scenarios, mobile quality inspection of production sites, and emergency sample preparation for scientific research field trips. It can be used for rapid sample preparation of metal parts, hardware accessories and engineering components on site, such as failure analysis of construction machinery parts, quality inspection of on-site hardware products, and sample preparation of field scientific research. It can also be used for small-scale sample preparation in mobile laboratories, providing convenient and efficient metallographic sample preparation solutions.
