Basic Machine

A universal vertical boring and milling machine type WF3/12, 6 axes under CNC, with the Fidia M2 or Fanuc 15 MB control in standard design. With one set of accessories to the machine. The machine is provided to the US market with 460 volt operating voltage, 60 cycles.

Six axes of motion:

• X = Longitudinal movement of table
• Y = Transverse movement of table
• Z = Vertical movement of spindle head carrier at column
• C = Circular movement of the table
• B = Rotation of the spindle from vertical to horizontal 90 degrees in 2 directions
• W = Movement of the milling spindle

Machine Accuracy

• Accuracy of the machine to VDI/DGQ 3441: Direct Path Measurement
• Position allowance: Tp = 0.02 mm/m or .0008/39.4" absolute to ± 3 sigmas.
• Repeatability tolerance: Ps = 0.01 mm or .0004" absolute to ± 3 sigmas.
• Volumetric Accuracy: 0.002" Overall

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 operator’s control panel.
