Dahao DH-V series high precision vertical machining center castingsusing Gray cast iron (FC300 or above) , in accordance with the internationalstandard (Jls G 5501) composition requirements, to the casting production,natural aging; all the assembly of the contact surface, for example,thecontact surface of the base and the column, the contact surface of the ballguide screw, the contact surface of the line rail and the contact surface ofthe motor base, etc. , effectively extend the life of the machine tool. Themachine tool structure is rigid enough, only the DH-V856L model weightreaches 7.2 tons,increases the main shaft to flush the water motor toreduce the tool wear, enhances the processing efficiency and the stability,also may choose the center outlet water and the auxiliary water tank.

The DH-V series high-precision vertical machining center castings of Dahao are made of gray mouth casting (FC300 or above), in accordance with the composition requirements of international standards (JIS G 5501), for the production of castings and natural aging; All assembly contact surfaces, such as the contact surface between the base and the column, the contact surface of the ball screw, the contact surface of the wire rail, and the contact surface of the motor seat, are processed by experienced technicians to ensure that the structure and accuracy of the machine tool can be stable for a long time and effectively extend the service life of the machine tool. The machine tool has sufficient rigidity, and only the DH-V856L model weighs 7.2 tons. Increasing the spindle flushing water and electricity reduces tool wear, improves processing efficiency and stability, and the center water outlet and auxiliary water tank can also be selected.
