Horizontal development for large workpieces from Danobat

DANOBAT is showcasing its HG-72 horizontal grinding machine in EMO Hannover 2017. It can machine workpieces of up to 3,000 mm long, 740 mm in diameter and 1.5 tons in weight.

The main advantage of this solution lies in its capacity to meet all grinding needs in a flexible way and can be adapted to clients’ demands.

The machine is fitted with a three-wheel head allowing for the machining of external, internal and curvic diameters. This spindle, which swivels on its own vertical axis and manages to reach all points on the workpiece, is driven by a 22-kW motor generating peripheral speeds of up to 60 m/s with wheels with a maximum diameter of 610 mm.

With these features, the machine can meet all grinding needs, including workpieces with Ra 0,1, in one set-up and guarantees geometric quality.

The machine is fitted with a DANOBAT MDM-400 multi-diameter measuring device which has, so far, only been available with the 300 and 500 models of this same range. The company has broadened its offer of this development and also has a wide selection of heads with an aim to adapting to the needs of each client.

The MDM-400 is capable of measuring diameters from 20 to 400 mm and works simultaneously with the machining process, a characteristic whose main advantage is the possibility to avoid the subsequent measuring process, and means that the grinding process is carried out in one operation.

DANOBAT’s MDM has a repeatability of ± 1.5 micron, it can measure diverse diameters and has the capacity to make post-process measurements once the grinding cycle has been completed and before the workpiece is removed.
