Cross-sectioning Cross-sectioning or microsectioning is a failure analysis technique for mechanically exposing a plane of interest in a die or package for further analysis or inspection.. It usually consists of sawing, grinding, polishing, and staining the specimen until the plane of interest is ready for optical or electron microscopy.
A Planar grinding machine, like the PlanarMet 300 planar grinding machine shown in Figure 3.3, utilizes a fixed abrasive stone for rapid sample grinding. This type of automated grinder produces planar samples in 1-2 minutes replacing up to 3 traditional grinding steps.
Our 8000 series Mixers/Mills® are high-energy ball mills that pulverize samples by shaking one or two sample vials with grinding balls, in a figure-eight motion, several hundred times a minute! Typical samples include hard or brittle samples such as rocks, minerals, cements, and ceramics.
EF1 Dry grinding - for the same range of work as wet grinding, dry grinding requires 1.3 times as much power as wet grinding. EF2 - Open Circuit Grinding - when grinding in open circuit ball mills, the amount of extra power required, compared to closed circuit ball milling, is a function of the degree of control required on the product produced.
In a drum mill the sample (usually pre-crushed material) is placed inside the drum with the grinding media (grinding balls or rods) and subjected to external forces. The Ball Mill and Rod Mill Modules are used for fine grinding of solid matter by impact and friction, in wet or dry condition.

A different method to produce a sample that has a very consistent amount of thermal damage. 48 Human Machine Interface (HMI) in Gear Manufacturing "Documentation is not a Substitute for an Intuitive Interface." The author explores the development of modern controls for a CNC gear grinding machine. 49 Cutting Down on Setup Time
A ball mill, a type of grinder, is a cylindrical device used in grinding (or mixing) materials like ores, chemicals, ceramic raw materials and paints.Ball mills rotate around a horizontal axis, partially filled with the material to be ground plus the grinding medium. Different materials are used as media, including ceramic balls, flint pebbles, and stainless steel balls.
Some general considerations during sample preparation are to minimize sample losses and to prevent contamination. Possible mechanisms for sample loss during preparation steps are discussed in Section 12.2.1, and the contamination of samples from sources in the laboratory is discussed in Section 12.2.2.
Metallography Grinder & Polisher - QGP Series of grinding and polishing machines offer practical and economical. Metallography Polisher - QualiPol Qualitest covers a complete and competitive range of metallography polishers such as the Metallography Polisher -.
8507R Multiple-Sample Rack permits processing of three smaller samples. 10-minute electronic timer with LCD display and environmentally safe, push-button membrane switch. Cam-activated clamp requires only moderate hand pressure to secure the grinding dish in the Shatterbox and is adjustable for containers of different heights.
Sample preparation, in analytical chemistry, the processes in which a representative piece of material is extracted from a larger amount and readied for analysis. Sampling and sample preparation have a unique meaning and special importance when applied to the field of analytical chemistry.
May 29, 2014· Grinding a herbal supplement by liquid nitrogen and a mortar and pestle. Use caution with liquid nitrogen.
The two concerns with cryogenic grinding is that the sample may warm up, and secondly, throughput is very low. Preventing sample warming can be done be adding additional liquid nitrogen to the mortar while pulverizing the sample. Low throughput is a more difficult issue as a mortar can only be used once before it must be cleaned.
Rough grinding produces a flat, plane surface and removes harmful effects resulting from cutting-off operations. It is advisable during the rough grinding operation to bevel the sharp edges of the specimen, or specimen mount to prevent tearing of grinding papers .
