Extreme Series Description

  • The working table executes only longitudinal movements; this ensures full contact and support from the machine bed, even in the limit position.
  • The column is fixed over arm carries out only cross feed movements, this guarantees uniform contact between the column slide and machine bed in any column position. The column slide is guided by box type, hand scrapped to obtain smooth stick slip free movements.
  • Vertical slide ways and the grinding wheels, creating a perpendicular movement of the spindle in relation to the working table, the housing construction is also designed for better rigidity.
  • The cartridge type spindle is supported by Class 7 Super (CP 4) precision angular contact ball bearings, preloaded and select-fitted into spindle cartridge. This will guarantee a maximum run out of 0.002 mm for stable and accurate grinding.
  • A Hydraulic overhead dresser is employed for Over Arm type and is mounted on the spindle head to allow the wheel to be dressed independent of the grinding height or column position.
  • The automatic lubrication system supplies lubricant to all of the guide ways and lead screws as the machine operates. This system ensures all the critical components are lubricated with the right amount of oil at all times.
  • The external independent hydraulic tank is located outside the machine to be easily accessible for maintenance. A specially designed valve enable smooth table reversing,
  • Electric components and functional modules are well arranged and packed in a separate electric cabinet to be easily accessible for maintenance. An independent control box with an ergonomically designed panel offers a comfortable and convenient operation environment.
