Delta

Rotary table models:
• Toothed belt drive and planetary gear unit 
• Electro-permanent magnetic chuck with
standard electronic control unit
Oscillating table models:
• Toothed belt drive
• Electro-permanent magnetic chuck with
standard electronic control unit
 

Rotary table supported
• In the Rotax 7, by a pair of pre-loaded high precision ball bearings with 25° contact angle
• In the Rotax 9 and 12, by an hydrostatic journal bearing and driven by a torque servomotor, which can be equipped with electro-permanent magnetic chuck.
 

Hydrostatic support on all machine 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
 

Mackensen hydrodynamic spindle
The spindle line has a Mackensen hydrodynamic bearing
on the front and a pair of pre-loaded precision ball bearings on the rear.
• Zero wear and, therefore, maximum durability 
• Zero friction (super accurate surface finishes) 
• High geometric and machining precision
