The machine tool is a gantry frame structure. There are left and right column, connecting beam and worktable base are connected to each other, forming a frame structure, by the gantry frame, the main transmission box, worktable, beam, beam lifting mechanism, left and right vertical tool rest, hydraulic device, electric control cabinet, etc.
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.

WORKBENCH STRUCTURE:
Table par is consisting of the workbench, table base, spindle components and transmission components.
Workbench and workbench base respectively for the overall casting structure, the use of high strength and low stress cast iron, grade HT250 aging treatment has sufficient rigidity, strength and stability. Workbench bearings using high precision NN30 series double row short cylindrical roller bearings, by adjusting the radial clearance to ensure high precision rotary table, and a high working life. Workbench guide rail for constant current hydrostatic guide, to ensure long-term stable work bench.
BEAM STRUCTURE:
By the beams, horizontal feed transmission structure, clamping mechanism and hydraulic device and other components.Beam using high strength and low stress cast iron, aging treatment, structural stability is not deformed, the guide after IF quenching, with sufficient rigidity, strength, to ensure the accuracy of the machine. The top of the guide rail is equipped with a weight-reducing and unloading device, which reduces the resistance of the tool holder during movement. The contact surface of the beam and the column guide rail is glued with PTFE wear-resistant guide rail soft belt, which has a small coefficient of friction and greatly prolongs the service life of the machine tool. Beam placed in front of the column, so that the vertical beam in the vertical column.
ELECTRIC SYSTEM
All machine control components such as contactors are installed in the power distribution cabinet. All the operating components are centrally mounted on the hanging button station. Machine electrical system and mechanical action set many chains, to ensure the machine control and mechanical movement of the reliability, safety, in the event of failure, just press the emergency button, the whole equipment power.
HYDRAULIC STATION
table static pressure system, the main transmission system, cross-beam clamping system, vertical turret ram hydraulic balance system. Static pressure system table by the oil pump, the static pressure oil is allocated to each oil pool, table height by adjusting the reach of 0.06-0.15mm. Hydraulic device pressure protection, such as the use of pressure will automatically shut down.
