Large Crankshaft Grinding Machine for Construction Machinery, Power Generation, Pumps, and Marine Applications

Capable of Large Crankshaft Grinding
 

  • The grinding of large size crankshafts presents challenges such as workpiece, unit size and weight increase, shaft deformation, positioning, and environmental factors. Komatsu NTC supports stable production with our many years of experience, extensive technology, and technical expertise.

     

Main features and specifications

High-Precision Positioning

  • The wheel head infeed uses NTC's unique hydrostatic slide and linear motor drive, combined with the NTC roundness correction system, to enable high-speed, high-precision profile grinding with reduced vibration.

High-reliability grinding wheel

  • The grinding wheel bearings utilize NTC's original hybrid hydro-static bearings with no metal contact, ensuring high rigidity, vibration suppression, and high stability.

Full automatic CNC workrest

  • All journals are automatically measured to prevent deformation of heavy shafts, and the CNC workrest is set to the optimal position.
    It can be adjusted to suit the characteristics of the shaft, improving operability and setup.

Environmentally and user friendly

  • The sealed overall cover and the localized sealed cover for the grinding area prevent the scattering of grinding mist.
    Besides, the automatic measurement function, correction system, and grinding status monitor support the operator.
