Traveling column surface grinding machine 1 600 x 650 mm | MINI 15
DELTA
The travelling column plane surface grinders of the MINI line are advanced technology machines designed and built to assure high production capacity, precision and reliability. The T-structure of the highest rigidity 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 stick-slip effects. The spindle, directly driven via coupling by a servoventilated motor, is supported on the wheel side by a nowear 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. Preloaded ball screws of precision ISO 3 ensure precise and stable positioning of the transversal and vertical axes. The table, driven by hydraulic cylinders, is controlled by an electronic proportional valve. 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. All the grinding machines of the MINI line are fully automatic and available with three different automation levels: DIASTEP, NC and CNC.
