Main drive uses a 30/37KW spindle servo motor, through a two-speed gearbox (auto 2 gears). |
Low noise, high reliability, energy saving |
Main motor is asynchronous motor --- high power consumption, low torque |
| 5 |
X, Z axes use Taiwan/Japan THK C3 class precision ball screws, pre-tensioned with Japanese NSK precision angular contact ball bearings and long-type double nuts preloaded, screw pre-stretched. |
Ensures excellent positioning accuracy. |
Use domestic ball screws, domestic bearings, no pre-stretching |
| 6 |
Table ways use high-precision rolling bearings; radial bearings are Japanese NSK/German FAG high-precision double-row short cylindrical roller bearings. Axial bearings are high-precision thrust ball bearings used as rolling guides, axially preloaded, thus improving table rotation accuracy and load capacity. |
Improved table rotation accuracy, speed 300rpm, load capacity 8T. |
Hydrodynamic guideways --- low speed, poor accuracy, low load capacity; speed 160rpm, load capacity 5T |
| 7 |
Optional: 4/5/6 station --- Servo hydraulic turret (hydraulic clamping force 9100Kgf; electric tool post clamping force 2000Kgf) |
Good rigidity, fast indexing |
Electric tool post --- poor rigidity, clamping force 2000Kgf |
