Delta Model Maxi 2000 / 750 Travelling Column Surface Grinder
Description
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…
