Machine
The DPM CNC hob inspection centers have been designed for rapid, automatic precision checking of all important hob deviations. The measuring centers have a capacity for hobs with tip diameters up to 300 mm and 200 kg respectively 600 mm and 400 kg. The machine design is horizontal for easy and save loading and unloading of heavy hobs. The tailstock has an inbuilt automatic force control to ensure constant clamping.
All components used, such as camera head, control, evaluation etc. can also be used for the modernisation of customer hob inspection machines.
