HG - Universal heavy-duty grinding with moving table
HG: universal heavy-duty grinding machine
These cylindrical grinding machines have been designed to fulfil the requirements of a wide range of applications from 1500 mm up to 5000 mm in length.
The most demanding industries can benefit from tailor-made configurations for turbine shafts, large transmissions, axles for rail units and landing gear components, among other examples.
Complex processes with in-process measuring, special dressing systems and custom enhancements have been developed accordingly. The structure of independent axes is ideal for a single or double wheelhead, to optimise versatility with sequential grinding operations.
- Workpiece length: up to 5000 mm
- Workpiece OD: up to 1040 mm
- Grinding wheel diameter: up to 915 mm

Advantages
- A wide range of wheelhead arrangements for OD and ID grinding operations.
- Single or double wheelhead configuration machine.
- One piece stabilized pearlitic cast iron machine base and sub assemblies.
- Machine V and flat guides are hand scrapped to ensure positioning accuracy and repeatability, correct surface contact and lubrication.
- Danobat high-frequency electro spindles with temperature control, improving grinding power and accuracy, minimizing vibrations.
- “B”-axis with integrated high precision torque motor for high positioning accuracy ensuring zero backlashes, less maintenance and longer product life.
- Multi-diameter absolute in-process/post-process measuring systems MDM.
- Additional contact or non-contact in/post process measuring devices.
- Grinding of all type of exotic materials: HVOF, glass, tungsten carbide, chrome, etc.
- DoGrind+
- Most relevant machining information displayed in a single view.
- A clearer, more comprehensive list of operations showing the main parameters so that they are easier for the user to understand.
- Multiple optional integrated modules; Profile editor, Contour module, Threads module, Forms module, CAD files import.
