Metalographic laboratory grinding polishing machine QPOL

The grinding and polishing process is automated by intuitive touch-screen controls. Easy manual loosening and tightening of sample holder for central pressure simplifies the preparation process. Grinding or polishing media is automatically changed and all parameters can be adjusted directly during the process.Grinding samples has many benefits for sample preparation since it increases homogeneity, increases surface area and decreases particle size which can improve extraction efficiency. Some of the negatives regarding grinding samples are: potential contamination, increase in moisture, evaporation, loss or alteration of volatile Principles of Sample Preparation by Grinding or Comminution

Grinding and Polishing Guide Buehler Metallography

Sample pressure is applied by the weight of the sample itself or by the addition of extra weights. The samples must be sufficiently rigid and typically should have a minimum total mass of 4 N [0.4 kg]. If the weight is too low, the samples could corrode or tarnish during the polishing. Figure 3.20 Preparation with sample holder and adding weight.Cutting and Grinding processes combined. Specimen Holder with Vacuum for standard slides. Built in micrometer with digital readout.

Sample Preparation Grinding and Polishing Kemet

With this simple process, your samples will be prepared automatically, ready for analysis. Equipped with a powerful 1.1 kW motor, the grinding/polishing station offers adjustable variable wheel speed ranging from 50 to 600 RPM, along with a soft start-stop function. It can accommodate 250 mm grinding/polishing discs.Fig. 2 illustrates the process of cutting out a 3 mm round TEM sample from a thin slice using a core drill to grind a circular channel through the slice. Grinding is made by the rotating metal tube drill bit and abrasive particles contained in a slurry. As the grinding process must erode the surface of the slice, it is most effective on brittle A precision core drill for transmission electron microscopy sample

(PDF) Design of a compact grinding machine ResearchGate

An initial design of the grinding machine was made using SolidWorks CAD software. A prototype was subsequently constructed and tested by using typical metallurgical sample preparation process withA 4 kW drive motor drives the grinding stone of the Qgrind XL and ensures high material removal and rotational speeds of up to 2000 rpm. The sample holder is driven in the grinding head with up to 1.1 kW, which means that grinding forces of up to 750 N can be achieved. The speed of both systems can be variably controlled.Qgrind XL Pre-Grinder Grinding / Polishing / Etching QATM
