UNIVERSAL MILLING CENTRE SHW-UniSpeed 5, Construction year: 2006
Basic machine with the travel paths:
Machine stand horizontal-longitudinal X = 2,000 mm
Vertical headstock slide Y = 1,300 mm
Headstock horizontal-transverse Z = 1,300 mm
Machine stand
In a compact, torsion-resistant welded construction.
Three hardened compact roller guides guarantee the transmission of high cutting performance with consistent quality.
Protected against chips and cooling water with covers.
Headstock slide
In cast design with hydraulic weight compensation, guided on the machine column with hardened compact roller guides.
Machine frame
Intrinsically rigid design in Hydropool composite construction as the basis for dynamic and vibration-damped movement of the machine frame in the X-axis.
Complex foundations are not required.
Compact roller guides ensure maximum precision.
