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.

Obtain an 8-10 mm piece of the main stone sample using the KemTech Geo's left side cutting station.; Roughen the surface of the glass slide to aid in securing the sample by grinding with the Lapping plate on the KemTech III using Silicone Carbide and water.; Attach the stone sample to the glass slide using KEPT epoxy resins, and place in the …
Find the sample holder with the right combination of capacity, sample size, and cutout shape. Buehler offers both central and single force sample holders to support all …
— By the end of grinding process, any cutting marks or scratches would have disappeared from the surface. The finer is the deformation surface at the end of the grinding procedure, the easier it is to carry out the polishing. ... The standard samples are usually small, so the user can mount more than one sample on the holder at the same time ...
Therefore, this paper analyzes the process of the robot abrasive belt grinding of the blisk and carries out relevant experiments to verify it. The experimental results show that: compared with manual polishing, the polishing efficiency is increased by 1.5 times; the blisk blades after polishing have good consistency, the milling cutter lines ...
— Grinding is usually a two-step process. The first step in the grinding process is known as plane grinding. Plane grinding is the process of making the entire surface similar. For example, if the sample surface had several raised areas, plane grinding would flatten those areas to a similar condition as the rest of the surface.
TargetGrip is a tiltable specimen holder. It accommodates mounted samples up to 40 mm in diameter. Adapters are provided for larger specimens, cross-sectioning, and parallel …
EMS maintains a wide selection of specimen holders and accessories, including those for scanning electron microscopy (SEM). focused ion beam (FIB), and scanning transmission electron microscopy (STEM) analysis.In general, specimen holders are the more complex mechanism that holds the specimen mount in position during imaging and can facilitate …

The beam divergence for the different sample holders was varied to ensure the beam did not hit any parts of the sample holder other than the sample. Measure-ment times for all samples differed according to the measurement setup, with a typical measurement tak-ing 8 – 10 minutes. 3 Results 3.1 Tablet composition and literature compari-son
This holder was developed to save fingers from grinding and burning, when surfacing samples on a grinding wheel or belt sander. The 40 lb. pull of the magnet, holds thesample. The retaining shield keeps the sample from sliding. A screw is used to break the magnetic field which allows removal of the sample from the powerful magnet.
