DELTA specialises in tangential grinding machines with travelling column and provides the largest range available on the market. 15 models - 3 automation levels.
The tangential rotary table grinding machines with travelling column and hydrostatic slideways of the ROTAX range are state of the art machines designed and manufactured to ensure high productivity, precision, and reliability
MANUFACTURING FEATURES
TRAVELLING COLUMN with stabilised Meehanite cast-iron structure:
maximum rigidity
removes a large amount of material
flatness guaranteed
With the travelling column, the wheelhead does not fall off. This solution eliminates the problem of the wheelhead falling off due to transverse travel and relative compensation measures.
HYDROSTATIC SUPPORT ON ALL MACHINE AXLES WITH FULL GRIP SLIDEWAYS. All the machine axles feature full grip hydrostatic slideways along the entire travel. 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
mandrino idrodinamico Mackensen
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. The result:
zero wear and, therefore, maximum durability
zero friction (super accurate surface finishes)
high geometric and machining precision
L11e
ROTARY TABLE supported by a pair of pre-loaded high precision ball bearings with 25° contact angle driven by a brushless servomotor, which can be equipped with electro-permanent magnetic chuck.
