1. This machine bed, column, spindle box and other key parts are used Meehanna (dense baking) castings, stable organization, permanent quality. Casting after finite element analysis computer calculation analysis, reasonable structural strength and strengthening rib collocation, to provide high mechanical rigidity. The casting material grade is GC-275, the casting structure adopts one-piece molding technology, box structure, and the machining adopts our large pentahedron machining machine, which can complete the machining in one clamping, and the machine tool has high rigidity, high strength, and excellent geometric positioning accuracy. And can ensure the long-term stability and high precision of the machine tool.
Note: Meebake castings casting process control with its application
Meehanite Metal Casting: Meehanite Metal Casting undergoes a series of strict casting process control, such as the control of graphite carbon (GC) and combined carbon (CC) content in the iron material, the control of the metallurgical quality of the molten iron, i.e., the cleanliness and the control of the degree of subcooling (Under Cooling degree). After CA-SI inoculation, and then do the wedge value (Wedge Value) of the control; do 5 elements, alloying elements and nitrogen (N) content control, etc., in the casting is very easy to obtain the expected Polaroid iron base and graphite distribution, and enhance the mechanical properties.
In order to prevent deformation after processing, the castings are thoroughly annealed, which is conducive to the elimination of internal stress.
Application of GC40(GC275)
Dense baking GC40 type is most suitable for casting homogeneous castings with a thickness of 10-15mm. This type of material has dense organization, good strength, proper hardness, low friction coefficient and self-lubrication, so after surface quenching treatment, it is widely used in workpieces where the friction of metal surfaces with each other causes thermal shock, such as the body of the tool machine, the headstock, the table and the cylinder liner, etc. It has a wide range of applications.

2. LU-800 overhead crane type 5-axis machine series adopts the high rigidity structure of U-shape base with bilateral support for A and C-axis rotary table, together with the standard 12,000rpm direct-junction high-speed spindle, powerful roller-type linear slideway and 3-axis precision optical scales and other high-quality parts. It achieves five-axis high-precision simultaneous control of X, Y, Z, A, and C axes, and easily accomplishes a variety of complex machining tasks such as milling, drilling, tapping, beveling, helical surface machining, and irregular surface machining.

five-axis machining continuous turning, chips and cutting fluid exclusion clean easily.
has the double effect of fast cutting and precise positioning.

12.A and C axes adopt direct-drive motor with angle decoder to drive the rotary table, which is more excellent than the traditional worm gear structure in terms of power transmission efficiency and performance of reducing power consumption.
High degree of freedom in the working area.
High table load (up to 1000 kg).
No debris accumulation on the table surface
Oscillating A-axis and rotating C-axis in the workpiece (U-shape)
Torsion prevention by double drive correction.

13.IDD is the best design for heat source isolation, heat source isolation of the spindle straight junction design, reduce thermal deformation, improve the accuracy and life of the spindle. Heat insulated coupling design between motor and spindle, the whole spindle can choose the oil temperature cooling control, can get higher precision control. The motor and spindle are directly driven without the noise, backlash, and vibration problems of belt or gear drives. The motor and spindle are directly coupled to enhance the efficiency of the motor, and the rotational speed is detected directly from the motor shaft, so that high quality and rigid tapping can be obtained.

14. Chips generated in the machining area can be properly handled, and the sidewalls with a large inclination angle can guide the chips to the bottom of the machine. In terms of chip removal function, a very simple and efficient chip removal mechanism is designed. Chips are carried by a large amount of cutting fluid from the chip flushing device to the tracked chip conveyor at the front of the machine, and then discharged to the chip accumulator on the right side of the machine by the tracked chip conveyor, so that the user can conveniently and simply clean up the chips.

15.LU-800 5-axis machining center is subjected to dynamic cutting test according to NAS979 standard to check the high precision performance of the machine.

16. The machining program cannot be started when the safety door is not closed to ensure the safety of the operator. When the safety door is opened during machining, the machining program is suspended to protect the operator's safety.
The machine is equipped with high-brightness working lamps, which are convenient for the operator to load and unload workpieces, measurements and other work.
The working lamps are dustproof, waterproof and explosion-proof.
The oblique light field function of the work lamp can concentrate the light source to the processing area.
