Advantages

  • The tilted table with adjustable tilt angle simplifies the installation procedure and allows machining of sealing surfaces at various tilt angles. 
  • The coordinate device ensures the part installation by three coordinates (tilt angle and positioning with respect to the x and y axes). 
  • To make installation procedure of workpiece more simple the column can turn on 290° relatively its base. 
  • Digital indication of spindle rotational speed is provided. 
  • The tool drawer unit allows to store replaceable accessories.
  • Uniform lapping plate and the adapter with eccentric allows to achieve high flatness of the surface.
