UNIPOL820 Dual 8-Inch Platens Grinder/Polisher with Magnetic Plates and Independent Speed Control for Metallographic Sample Preparation
The UNIPOL820 is engineered to meet the demanding needs of metallographic laboratories requiring efficient and precise sample preparation. This dual-platens grinder and polisher is designed to accelerate the processing of small samples by providing two independent 8-inch diameter lapping plates, each with its own speed control. This configuration allows simultaneous or separate operation of the platens, enhancing workflow flexibility and throughput.
The machine incorporates upgraded magnetic plates that facilitate rapid and secure attachment of sandpapers and polishing pads, significantly reducing setup time. Its robust construction features a heavy-duty cast frame with a black bright paint finish, ensuring durability and stability during operation. The belt-driven platens operate quietly and smoothly, while a soft rubber splash guard ring enhances operator safety by containing splashes during polishing.
