750DB cnc engraving machine

 2 spindle CNC engraving machine

 

 

Equipment features:

 Main structure of the machine tool: The whole machine (base and bed) is made of natural marble, which will not deform permanently, has good shock absorption effect, is not affected by temperature, has high processing accuracy, and has good high-speed operation stability.

 Main accessories: Taiwan Hiwin, original precision linear P-grade guide rails, Japan NSK high-precision bearings, C3 grinding-grade high-precision ball screws (0.008mm/300),

high-speed rotation high-power spindles.

 Control software: Control software: adopts absolute value control method, and the control system and driver are closed-loop to achieve high-speed and precise control.

 Domestic No. 1 brand Proton automatic lubrication and refueling system: The key precision parts such as the screw and guide rail on the machine tool are equipped with oil circuits, which automatically control the time to supply oil to them, and can also be maintained in working state.

 Newly designed automatic lubrication system, which keeps lubricated moving parts for a long time.

 Dustproof system: The key precision parts such as the screw and guide rail on the machine tool are equipped with waterproof and dustproof devices, and secondary waterproof and dustproof protection.

 Cooling circulation system: three-stage filtration and two-stage sedimentation filtration system, effectively improves the cooling effect of the cutting fluid and prevents impurities in the cutting fluid from affecting the processing effect.

 New water protection design, more effectively protects the guide rails, screws, bearings, motors, and other core components.  Equipped with the second-largest domestic brand Ruike chiller, with high stability, the working state ensures that the high-speed and high-precision spindle can operate normally at a constant temperature to ensure accuracy.
