Delta Model Maxi 2000 / 750 Travelling Column Surface Grinder


Travelling column with stabilised Meehanite cast iron structure. All the machine axes feature full grip hydrostatic slideways along the entire travel. The spindle line has a Mackensen hydrodynamic bearing on the front and a pair of pre-loaded precision ball bearings on the rear. DELTA MAXI Series travelling column grinding machines are available in 9 models with grindable surfaces from 1200 x 750mm to 3000 x 1100mm with 2 different levels of automation: – NC or CNC.

Travelling Column 
with stabilised Meehanite cast-iron structure: With the travelling column, the wheel head is fully supported.

  • maximum rigidity
  • removes a large amount of material
  • flatness guaranteed

Hydrostatic support for all axes with full grip slideways. All the machine axles feature full grip hydrostatic slideways; therefore, the table always rests on the basement for the entire longitudinal travel; the same criterion applies to the column and the wheelhead. This involves:

  • absence of anti-friction material (turcite)
  • zero friction (optimal exploitation of the installed power)
  • zero wear (geometry guaranteed for a long period of time)
  • No stick-slip. Extremely smooth movements

The proof? Pressing the table with one finger is all it takes to move considerable loads. See the videos...
