The machine consists of a closed, thermally symmetric gantry frame with right columns, intermediate connecting beams and bench base. The main large and medium castings are cast with high strength and low stress cast iron. Large castings have reasonable design structure, high strength and high rigidity; All castings are treated with thermal aging and vibration aging twice to eliminate internal stress and ensure long-term maintenance and stability of the accuracy of the machine.
A vertical tool rest is arranged on the beam. The right tool rest is a CNC tool holder, which is rotated by the ball screw driven by the servo motor through the planetary gear reducer to realize the horizontal or vertical movement of the tool holder.

WORKBENCH STRUCTURE:
The workbench part is composed of the workbench, the workbench base, the main shaft and its transmission mechanism. The table and the base of the table are cast and machined. The thermal symmetric structure of the table and the base of the table can reduce the thermal deformation of the table, so as to reduce the influence of thermal deformation on the processing accuracy, and maintain the long-term stable work of the table.
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 stations include:
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.
