Grinding of turbine for power generation

It's a grinding machine for grinding high precision model HG-91-4000-B8 for the grinding of turbine shaft.

Companies belonging to the generation of energy and aeronautics sector are known for their high technological requirements in all the elements that use. High standards of safety, environmental, control, etc. that apply imply a very high level of technological development and investment compared to other sectors.

For many years, Danobat, in the crest of the technology in the manufacture of machine tool, has expressed its commitment to this kind of needs, designing and developing high level solutions for the grinding of critical components for gas turbines of power generation and aircraft engines and landing gear.

The HG-91-4000-B8 machine supplied by Danobat provides a comprehensive, accurate and reliable solution in the grinding of all the diameters, faces, radios and cones of the shaft of turbine in a single bound. Machining the workpiece in a single subject is a "sine qua non requirement" to obtain the maximum geometric accuracy and a minimum level of manipulation of the piece.

The difficulty of the management of the piece and the complexity and number of operations to perform (18 operations in a same piece), make the HG-91-4000-B8 is a perfect solution for the user, so far performed the piece in several tied. Saving time and improving accuracy are the first result.

The machine is equipped with two hydrostatic grinding wheel heads mounted on a continuous turntable powered by an integrated engine of high free of any mechanical transmission torque, patented by Danobat. Each of the heads are independent with their own electro-husillo, balancer, etc. to be able to adapt to different grinding operations of the piece.

Reliability is another critical in such processes. The complete measurement automatic of the workpiece during the process of grinding and at the end of the cycle, guarantee.

The machine has an absolute multi-diameter for the control of cylindrical and conical surfaces during the grinding process, guaranteeing the maximum dimensional accuracy. In addition, the piece in automatic cycle measurement "Post-process" and its corresponding graphic registration, remove all kinds of manual checks.

Finally, the machine incorporates a meter on the head grinding wheel for the correction of taper at the beginning of the grinding process and the measurement of cones during the cycle. This correction is done automatically by the counterpoint of double motorized Corps.

Reliability, autonomy, precision, quality and efficiency are factors that make Danobat a reference worldwide in the field of the power generation and aerospace. For this reason, leading manufacturers of turbines in the world machining components with the grinding machines Danobat brand.
