HERZOG expertise in seperating and stamping

Some sample types will have to be sectioned or cut before they can be prepared for further chemical analysis. As an example, cylindrical or conical samples (so called bomb samples) are separated at the center and the surface of one of the pieces is ground or milled. Afterwards, the chemical composition of the sample can be determined by using, e.g., optical emission spectroscopy. Furthermore, a slice can be cut from a cylindrical sample. Subsequently, small pieces are punched out of the slice for combustion analysis.

Cutting

Some sample types will have to be sectioned or cut before they can be prepared for further chemical analysis. As an example, cylindrical or conical samples (so called bomb samples) are separated at the center and the surface of one of the pieces is ground or milled. Afterwards, the chemical composition of the sample can be determined by using, e.g., optical emission spectroscopy. Furthermore, a slice can be cut from a cylindrical sample. Subsequently, small pieces are punched out of the slice for combustion analysis.
Usually, abrasive cutting is the preferred method for separating of samples made from unalloyed to high-alloyed steel including special alloys and hardened steel. There is a wide range of benefits of this technology: Virtually all metal materials are workable, cut surfaces are even with a very good surface finish, preparation time are extremely short and there is minimal burr formation.
In most cases, cutting wheels have different mixtures of aluminium oxides as abrasives. In rare cases, also silicon carbide is used. The performance of the cutting wheel is also determined by grain size, degree of hardness representing the adhesion strength of the abrasive grain, structure, type of binding and reinforcement.
HERZOG is offering manual and fully automatic machines for cutting of samples. The design of the automatic cutting machines is focused on short preparation times to allow a chemical analysis as quick as possible. At the same time, all machines are optimized for an efficient heat dissipation and chip removal.

Punching

Metals are widely used due to their wide range of properties, which are tailorable for every specific application. The individual properties of metals are strongly controlled by the elements carbon, sulfur, oxygen, nitrogen and hydrogen. Even little changes in concentration alter the mechanical properties like, e.g., ductility, corrosion tendency or brittleness. Combustion analysis is the method of choice whenever highly precise and fast analysis of these elemental concentrations is required. Thus, optimum properties of metals are assured by applying combustion analysis with Elementar’s inductar series.
HERZOG offers various solutions for collection of samples for combustion analysis. On the one hand, chips can be collected during milling using the Chip Capture Unit (CCU) in the various milling machines. The operator can take the chips from a cup for further processing. Alternatively, chips can be sent automatically and pneumatically to the combustion analysis unit. On the other hands, small pieces for combustion can be punched from disk or double-thickness samples. This is done using the HUST which is available as a semi-automatic or fully automatic version. In the semi-automatic HUST, depending from the used matrix, a different number of punched pieces is produced and provided within a cup. In the fully automatic HUST, the punched pieces are singled and sent pneumatically to a magazine or combustion unit for analysis. The HUST is available with various options including a sand blasting unit for surface cleaning, induction heating unit for very brittle samples and cooling unit. HERZOG is cooperating with all leading manufacturers of combustion analysis devices.
