Cylindrical grinding with the cylindrical grinder HG 2

HG 2 – the efficient solution for the cylindrical grinding of shafts

Finding the right balance between flexibility and productivity is the high art of designing machines for cylindrical grinding. This demand is met with the HG 2 machine for cylindrical grinding. From batch sizes of 50 shafts up to and including 3-shift operations every application of the cylindrical grinding technology for shafts is covered. The object of the HG 2 is to provide a manufacturing solution for the cylindrical grinding of shafts at an attractive price. This has been achieved with a high degree of standardisation and the modular design of this cylindrical grinder. The HG 2 with cylindrical grinding technology is available as a manually loaded machine or an automatically loaded version that uses a gantry. The automated version can be used for the cylindrical grinding of workpieces between 150 to 400 mm (the manual version up to 600 mm) in length. The services offered in conjunction with the machine include the following options: process design, setting up the cylindrical grinding process, commissioning and assistance during production.

When EMAG introduced the HG 2 series to its horizontal grinding machine platform it took into account all the demands made on modern cylindrical grinders. In fact, with the HG 2 External Cylindrical Grinder EMAG presents a new, highly productive and exceptionally flexible machine concept for the grinding of small, medium and large batches of shaft-type components.

The quality requirements for ground components in particular are increasing all the time. In addition to that, process integrity is also a highly important criterion in cylindrical grinding.

The horizontal cylindrical grinder HG 2 from EMAG takes into account all the requirements that need to be met with the cylindrical grinding process. The thermostable cast iron base of the cylindrical grinder HG 2 carries the compound slide and is of high static and dynamic rigidity. The sturdy compound table design reduces the footprint and saves on expensive floor space. It also makes the exchange of grinding wheels easier. The HG 2 is equipped with precision ball screws. In combination with absolute measuring systems in X- and Z-axis (glass scales) this guarantees greatest precision in cylindrical grinding. The machine is separated from its envelope and the automation equipment to ensure that vibrations have no adverse influence on the cylindrical grinding process. NC tailstock and integrated automation ensure the cylindrical grinding machine is flexible enough to accommodate a variety of workpieces. It is thus possible to machine different shafts and workpiece variants on a single cylindrical grinder using cylindrical grinding technology. Anti-friction bearing-supported guideways in all linear axes allow for the tiniest infeeds with excellent continuity of all movements. The stick-slip free, well dampened infeeds result in outstanding contour accuracy and exceptional surface finishes in the application of the cylindrical grinding technology.
