Detailed introduction of MPT-I and MPT-II grinding and polishing heads: The MPT-I/II grinding and polishing head is developed and designed through various market research and extensive listening to user requirements. It is an economical product that is very suitable for use in small laboratories with moderate sample preparation quantities. Both MPT-I and MPT-II can be used for the preparation of individual specimens. The forces acting on each sample can be controlled separately, so one, two, or three samples can be prepared at a time without the need for empty or "fake" samples. The MPT-I/II grinding and polishing head can be conveniently connected to various grinding/polishing machines produced by Weiyi Company, with simple and fast operation, high sample preparation quality, and equipped with an adjustable drip dosing device. It is an ideal choice for industrial and mining enterprises and research institutes to achieve unmanned preparation, save preparation consumables, and improve sample preparation efficiency. Technical parameters: Power supply: 220V or 380V 50HZ Speed: 50rpm Force acting on each sample: 0-40N Number of samples prepared: 1-3 MPT-I and MPT-II grinding and polishing heads can be conveniently connected to various grinding/polishing machines produced by our company
