HB 3000: Automatic Grinding Machine

Automatic sample preparation improves reproducibility
The fully automatic HB 3000 cup wheel and abrasive belt grinding machine permits automated sample preparation for spectroscopic analysis with all its advantages. Operation with program-controlled grinding processes results in a considerable improvement in the reproducibility of sample preparation and therefore consistent analysis results at reduced time and cost. 

Best machining time
The HB 3000 is characterized by its rapid and precise grinding of iron, steel and particularly high-alloy steel samples in a wide range of geometries, the temperature of which may reach 800 °C. A pneumatic clamping unit enables symmetrical samples with a diameter of up to 60 mm to be gripped reliably and in a defined manner.

Processing of incandescent samples
The HB 3000 is equipped with program-controlled intermediate cooling during the grinding processes to ensure optimum grinding results. This cooling system enables incandescent samples to be processed.

Flexible grinding parameters
In conjunction with the abrasive, grain and hardness, the integration of cup wheel and abrasive belt into a single machine ensures that preparation of the sample meets the requirements of analysis perfectly. The abrasive belt, for example, is suitable for absolutely exact fine grinding of high-cost calibration samples. Conversely, optimum service life is achieved with coarse grinding by means of the cup wheel.

Fine grinding on the 200 mm wide abrasive belt offers advantages which are evident in the quality, service life, and low costs of abrasives. The width of the abrasive belt enables different samples to be ground on a number of tracks, which reduces material costs and saves time owing to the reduces wear on the abrasive belt and the increased intervals between belt changes.

The facility for preselection of abrasive belt zones prevents the transfer of material from one sample type to another and the consequent falsification of the sample characteristics. In addition, the HB 3000 enables the cup wheel and abrasive belt to be used not only in combination but also separately as programmed by the user.

HB 4000: Automatic Grinding Machine

Precision at high speed
The HB 4000 is characterized by quick and precise grinding of iron and steel samples with widely differing compositions, geometries, hardnesses and temperatures up to 800 °C. A pneumatic clamping unit allows symmetrical samples with diameters of up to 60 mm to be gripped reliably and in a defined position, thus enabling high grinding capacities and short sample preparation times.

Combination of different grinding techniques
Roughing on the coarse belt grinding offers long service life. The fine grinding of extremely hard samples on the 200 mm wide grinding results in higher quality, longer service life, and lower abrasive costs.

The width of the grinding belt enables different samples to be fine ground on several tracks – this reduces cutting material costs and time due to reduced grinding belt consumption and replacement. Preselectable grinding belt zones prevent cross-contamination of the samples during the preparation of different sample qualities.

The HB 4000 with its integration of the different machining methods, "Coarse Grinding " and "Fine Grinding" ensures optimum sample preparation for the analytical requirements for samples with all degrees of hardness and alloys.
On steel with very low carbon contents, abrasives can leave residues in the form of minute carbon particles which lead to falsified and useless analysis results. For these samples the "Automatic Grinder and Miller HBF 4000" is available.

HBF 4000: Automatic Grinding & Milling Machine

Combined advantages of grinding and milling within in one machine
The HBF 4000 abrasive belt grinding machine permits fully automatic sample preparation for spectral analysis with all its benefits. The method of operation with program-controlled grinding process offers significant improvements in the reproducibility of the sample preparation and thus accurate analysis results in less time and at lower costs.

Shortest machining time with the highest precision
The HBF 4000 is characterized by quick and precise grinding and milling of iron and steel samples with widely differing compositions, geometries, hardnesses and temperatures.  A pneumatic clamping unit allows symmetrical samples with diameters of up to 60 mm to be gripped reliably and in a defined position, thus enabling high grinding capacities and shirt sample preparation times.

Effective grinding
Roughing on the coarse belt grinding offers long service life. The fine grinding of extremely hard samples on the 200 mm wide grinding results in higher quality, longer service life and lower abrasive costs. The width of the grinding belt enables different samples to be fine ground on several tracks – this reduces cutting material costs and time due to reduced grinding belt consumption and replacement. Preselectable grinding belt zones prevent cross-contamination of the samples during the preparation of different sample qualities.

On steels with very low carbon contents, abrasives can leave residues in the form of minute carbon particles which lead to falsified and useless analysis results. For these samples, use of the mill instead of fine grinding after coarse grinding is, therefore, the right decision. Finish cutting of steel samples with low carbon contents using the milling cutter guarantees precise analysis results for evaluation.

The HBF 4000 with its integration of the different machining methods, "grinding belt" or "milling cutter" for fine machining, ensures optimum sample preparation for the analytical requirements for samples with all degrees of hardness and alloys. The HBF 4000 also allows the grinding belt and milling cutter to be used not only in combination but also for separate grinding and milling operations.

HTS 2000: Semi-automatic Grinding Machine

Reproducible grinding for precise analyses
The HTS 2000 cup wheel grinding machine prepares iron and steel samples of all conceivable geometries for spectral analysis. The grinding process is controlled by a PLC control system. The reproducibility of sample preparation is improved considerably. The grinding support is driven by a servo motor. Cup wheel wear is monitored by a measurement facility. This ensures extremely precise grinding results in conjunction with short processing times and long service life.

The sample temperature may be up to 900°C. The sample is cooled during the grinding process with compressed air or by liquid coolant, depending upon the machine configuration. The tank for the cooling facility can be removed from the enclosure in a few simple steps for fast and straightforward cleaning.

Numerous options for different requirements
A hydropneumatic clamping fixture is available for clamping samples of any given geometry. An electromagnetic or permanent magnet clamping plate is available for use with magnetic samples. Cup wheels are available with a range of hardnesses and grains. This assures perfect adjustment to a range of different sample material.

PLC for precise, simple and safe grinding
All parameters required for sample processing are entered on an operator terminal. They can be saved and protected by a password. The subsequent operating cycles are then controlled automatically by the program controller. Maloperations are virtually impossible. Grinding results can be reproduced at any time.

The machine is fully enclosed and therefore generates low noise. It corresponds to the effective safety standards. A dust exhaust facility can be connected without difficulty as the machine is equipped with a connecting sleeve as standard.

HT 350: Manual Grinding Machine

Precise surface grinding
HT350 is a manual disc grinding machine for sample preparation of iron and steel samples. It offers an excellent grinding performance with precision surfacing.

Efficient, fast and precise
By means of the HERZOG Dual Disk Surface Grinder, it is possible to achieve a precision flat surface of iron and steel samples with reduced material cost.  Coarse and fine grinding on two separate grinding discs is possible using one machine. The abrasive paper is solely affixed to the grinding disc by vacuum, eliminating the requirement of glue or any other fixing material.

This unique feature ensures a flat surface. Cheaper abrasive papers can be used still resulting in excellent flat surfacing.  In order to obtain an excellent grinding performance, each disc has its own driving motor. The correct selection of abrasive papers with respect to the grain and hardness will give a proven performance for the best analytical results.

Clean working with maximum of safety
The excellent integrated dedusting system with a spark trap and easily replaceable filters guarantees a healthy dust – free atmosphere. This machine is completely enclosed except for the small operating segment. It is fitted with safety switches and with the use of mechanical sample holder ensures maximum operator safety.

Further operator safety is guaranteed by circuitry which activates a break stopping the disc immediately the top cover is opened or the panel main switch is switched off.  The ergonomic height of 1000 mm means the operator is positioned at a convenient and comfortable height to use the machine.
