- Distance between centers ranges from 600 mm (23.62 in.) to 2,000 mm (78.74 in.).
- Maximum turning diameter and work length correspond to these dimensions.

3. Axis Travel and Movement
- X-axis travel varies by model, with upper (U) and lower (L) axis ranges specified, e.g., U: 290 mm (+210 to -80), L: 195 mm (+155 to -40).
- Z-axis travel ranges from approximately 1,015 mm to 2,075 mm depending on upper or lower axis.
- Y-axis and C-axis rotations are specified, with C-axis capable of 360° rotation.

4. Spindle and Speed
- Spindle speeds range from 45 to 5,000 rpm, with some models featuring two auto ranges via VAC motor coil switching.
- Spindle nose types conform to JIS standards (A2-6, A2-8, A2-11).
- Bore diameters and front bearing diameters are provided, e.g., bore diameter 40 mm (1-1/2 in.).

5. Tooling and Turret
- Tool stations vary between 8 to 12 per turret.
- Tool shank heights are typically 25 mm (1 in.) or 40 mm (1-1/2 in.) with VDI shank standards.
- Indexing times for turret tool changes are approximately 0.18 to 0.23 seconds per station.
- Turret types include V8, V10, and V12 NC turrets, with multitasking capabilities.

6. Power and Drive Systems
- Spindle motors range from approximately 3.3 kW (4.5 hp) to 7.0 kW (9.5 hp) depending on continuous or 30-minute rating.
- Live tool motors and axis drives are specified, e.g., XA: BL 4 (5.4 kW), ZA: BL 6 (8.1 kW).
- Coolant pump power is around 0.8 kW (1 hp).

7. Feed Rates and Rapid Traverse
- Rapid traverse rates for X and Z axes are up to 20,000 mm/min (787 ipm) and 25,000 mm/min (984 ipm) respectively.
- Cutting feed rates are adjustable from 0.001 to 1,000,000 mm/rev (0.0001 to 40,000 ipr).

8. Physical Dimensions and Weight
- Machine heights range from approximately 2,176 mm (85.66 in.) to 2,641 mm (103.98 in.).
- Floor space requirements vary from 2,950 x 2,050 mm (116 x 80 in.) to 6,500 x 2,813 mm (256 x 111 in.).
- Machine weights with CNC system range from 6,400 kg (14,080 lb) to 17,000 kg (37,400 lb).

9. CNC Control and Additional Features
- CNC systems used include Okuma OSP-P200L.
- Features include live tooling, multi-axis control (X, Z, Y, C), and optional quill specifications.
- Indexing and turret tool change times are optimized for productivity.

10. Notes and Standards
- Measurements are provided in metric units with inch equivalents.
- Spindle and turret standards conform to JIS specifications.
- VAC integral motor/spindle technology is used for spindle drives.

This summary captures the critical technical parameters, capacities, and operational features of the LU series CNC machines, facilitating comparison and selection based on machining requirements and workspace constraints.
