It is composed of worktable, worktable base, spindle device and transmission mechanism.
The working table has the function of starting, stopping, moving and changing speed. The spindle is equipped with a double-row centripetal short cylindrical roller bearing, and its inner ring has a taper hole. The radial clearance is adjusted to ensure the spindle accuracy. The worktable adopts constant current hydrostatic guide rail to bear the load in the vertical direction. The machine tool can work normally under the ambient temperature of 0--40ºC.
The gearbox is driven by a 55KW AC motor, and the gearbox is driven by a hydraulic cylinder to achieve 16 gearshifts. The gear material is 42 chromium molybdenum, which is treated by high quenching, and the hardness reaches HRC52-58. The tooth surface grinding tooth can achieve the precision of 6 grades.

WORKBENCH STRUCTURE:
The working table has the function of starting, stopping, moving and changing speed. The spindle is equipped with a double-row centripetal short cylindrical roller bearing, and its inner ring has a taper hole. The radial clearance is adjusted to ensure the spindle accuracy. The worktable adopts constant current hydrostatic guide rail to bear the load in the vertical direction. The machine tool can work normally under the ambient temperature of 0--40ºC.
THE LEFT TOOL REST IS DVT CONTROL
THE RIGHT TOOLREST IS CNC CONTROL
BEAM PART
It is composed of beam, horizontal feed transmission structure, clamping mechanism and hydraulic device. The beam is made of high strength and low stress cast iron, which has enough stiffness and strength. After aging treatment, it can ensure the precision of the machine tool.
ELECTRIC SYSTEM
The machine tool is controlled by Fanuc 0i-TF numerical control system, and the DVT tool rest is controlled by PLC. The system control elements and motor drive units are installed in the independent distribution cabinet, and all the operating elements are centrally installed in the floor cabinet type button station. The operation control part is concentrated on the independent floor operation platform, the CNC tool rest and the DVT tool rest are equipped with hand-held units respectively, the operation is simple, convenient and flexible.
GANTRY
Gantry from the left and right columns and connecting beams. Box in the upper part of the gantry around the lift, driven by AC motor through worm pairs and pairs of screw rail to do the lift move the beam along the left and right columns. Machine left and right column, connecting beams and other large high-intensity, low stress HT250 cast iron materials, the hardness of HB170-190, so that the machine has greater strength and high stiffness, aging treatment, eliminate stress and ensure that the machine accuracy.
