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.
GANTRY FARME
The gantry frame consists of left and right columns and connecting beams. In the upper part of the gantry frame is a lifting box, driven by AC motor, through worm gear pair and double screw to make the beam along the left and right column guide rail to do lifting and moving. Machine tool left and right columns, connecting beams and other large parts using high strength, low stress cast iron material, hardness HB170-190, so that the machine has a greater strength and higher stiffness, after aging treatment, stress elimination, the accuracy of the machine tool
Normally closed super-large caliber ultra-low pressure drop
Low fault, very long service life
TOOLREST:
The right tool rest is a CNC tool holder. The AC servo motor at the right end of the beam is controlled by the CNC system, and the horizontal ball screw is driven by the planetary reducer to rotate, so that the right tool holder moves horizontally on the beam. The CNC system controls the AC servo motor at the upper end of the rotary slide of the tool holder, through the planetary reducer, Drive the vertical ball screw to rotate, and the tool rest slider moves up and down.
