Improved Base for all Machines of the Horizontal G Series
The new GP 500 H features an array of innovations and establishes at the same time the new improved base for all machines of the horizontal G series. The GP 500 H is fitted with an additional CNC axis, which allows working with two separate spindles instead of just one. Both spindles can be equipped with one grinding wheel or sets of two wheels each.
Single gearings are roughed on the first spindle and finish ground on the second spindle with one grinding wheel on each spindle. Two gearings on one shaft can be roughed and finished with wheelsets on each spindle avoiding tool or format changes. Generally, two different drive variants are available with different power output and speeds for different sizes of grinding wheels. Further spindle options depend on the external diameter and width of the required grinding wheels making the machine even more flexible.
Internal gears can be manufactured based on the twin drive principle without spindle change as well. Format changes are now considerably faster executed than before. This is true for changes between external and internal grinding spindles as well, since simple adapter interfaces can be connected fast and easily by the machine operator. The GP 500 H employs electroplated CBN or dressable corundum grinding wheels depending on the workpiece requirements, delivery time and lot size to be manufactured.
