 High grade cast iron bed is designed to damp vibration and assures high accuracy. 60 ° slant bed structure provides smooth chip removal and more convenient handling of the workpieces, and ensures accuracy stability. |
| An extremely precision cartridge type main spindle rotates without vibration, driven by a powerful AC spindle motor. ZF two gearshifts reducer and spindle box gears deceleration make large torque and smooth running possible. |
| Imported 8-station hydraulic turret makes tool change rapidly and reliably. |
| The sliding guideways surface of carriage and slide adopt special plastic-coated material. The bed sliding guideways surface undergoes intermediate frequency quench and precision grinding. The carriage uses hydraulic cylinder to balance the weight of turret so that the machine has good dynamic responsibility and high accuracy retainability |
| Integrated full-enclosed guard of machine,which is clean and environment-friendly. The centralized machine operation panel made operation more convenient and more prompt. |
