Mechanical Design
Single column machine with large longitudinal, cross and vertical traverses. Bed-type
design with rugged absorption of cutting forces and workpiece weights by well-dimensioned
design of the bed, column, and cross-slides. Cast-iron construction providing large
static/dynamic rigidity. Slideway faces of dense structure, mating counter-guideways with
anti-friction coating, giving a balanced relationship between static and dynamic friction.
Additional transverse guidance via preloaded, hardened and ground roller bearings.
All controlled axes are equipped with individual fast response and maintenance-free, AC
servo motors. Feed drives of axes X, Y, Z are designed without backlash, via preloaded,
precision ball bearings and preloaded gears.
The milling head may be swiveled through 90 degrees to the horizontal position on
either side of vertical. Integral with the milling head is a 300 mm or 11.81" boring
slide which may be fed either at feed or rapid traverse, at any angular position of the
head.
- Automatic programmable hydraulic clamping of all axes.
- Measuring system for X, Y, Z by Heidenhain Linear Scale.
- Slip clutch on main drive with disconnection of feed drive in case of overload.
- Coolant circulation equipment.
- Automatic central lubrication for longitudinal, transverse, spindle head carrier and
milling slide motions.
- Flexible steel way covers for X, Y, Z axes.
- Low noise level: La max. 75 dab. Sound level transmitted by air La max. = 75 dBA will
not be exceeded.
Separate control cabinet, main switch with safety interlock, power pack and control
components to ruling VDE standards for machine tools. AC main spindle motor, air cooled
with filter. Hardwired and software limit switches safeguard each axis end position from
over travel. Control voltage 110 volts AC and 24 volts DC. Pendant mounted operators
control panel.
