MAXI
Traveling column surface grinding machines with 2 automation level:
CN compact plus / CNC diatronic
9 models: 1200/750 - 1500/750 – 2000/750
2000/1000 – 2500/1000 – 3000/1000
2000/1100 – 2500/1100 – 3000/1100
Max. grindable surface: 1200x750(775) ÷ 3000x1100 mm
The traveling column plane surface grinding machine of the MAXI line are advanced technology machines designed and built to assure high production capacity, precision and reliability. The T-structure of the highest rigidità is made from stress-relieved Meehanite cast iron. All machine axis slideways (table, column and wheelhead) are hydrostatic. The hydrostatic lubrication, eliminating sliding friction, allows to use all the power installed and to achieve extremely regular and precise movements without wear and stickslip effects.
The spindle (original DELTA design) is the fruit of many years of study and experimentations, and is one of
DELTA grinding machine strong points. The spindle, directly driven via coupling by a servoventilated motor,
is supported on the wheel side by a no-wear hydrodynamic bearing of the Mackensen type providing for very
smooth rotation and very quiet operation. A pair of preloaded precision ball bearings are mounted at the back.
The attention paid to the ergonomy of the machine, provided with complete protection, allows the operator
of a very good view and to work very easily under the best safety conditions, simplifying loading and unloading
operations.
