1. This machine bed, column, spindle box and other key components 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 geometrical positioning accuracy. And can ensure the long-term stability and high precision of the machine tool.
Note: Meebake castings process control with its application
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. After CA-SI inoculation, and then do the 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 coefficient of friction and self-lubrication, so after surface quenching treatment, it is widely used in the 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 uses.

     The spindle direct junction design isolates the heat source, reduces the thermal displacement, and improves the accuracy and life of the spindle. No belt or gear drive noise, backlash, vibration problems. And enhance the efficiency of the motor, directly from the motor shaft to detect the speed, can obtain high quality and rigid tapping. There is a heat insulated coupling design between the motor and spindle, and the spindle has oil temperature cooling control, which can obtain higher precision control.

    The tool magazine has a capacity of 30 tools, which allows for loading and unloading of tools while machining.

    The arm-type tool changer and magazine are mounted on the left side of the machine to minimize the waiting time for tool preparation.

    Quick tool change time is 3 seconds (T to T).
 

    In the chip removal function, a very simple and efficient chip removal mechanism is designed. Chips are carried to the chip conveyor in front of the machine by a large amount of cutting fluid from the chip flushing device, and then discharged to the chip accumulator on the left side of the machine through the chip conveyor, so that the user can conveniently and simply clean up the chips.
 

    Convenient and simple maintenance design

    The tool magazine is equipped with maintenance door, which is convenient for loading and unloading tools and maintenance.

    Hydraulic piping and oil cooling system piping are centralized at the back of the machine for easy maintenance.

    The wiring in the electrical box complies with CE safety standards to ensure that the control system operates without external interference.

    High-performance numerical controllers are systematized and networked to meet the needs of the high-speed and high-precision era.

    The electric box adopts wall-mounted heat exchanger, so that the hot air inside the electric box can be discharged quickly to stabilize the operation of the control system.
 

    High-performance configurations

    Safety gate system: When the safety gate is not closed, the machining program cannot be started, ensuring the safety of the operator.

    When the safety gate is opened during machining, the machining program is suspended to protect the operator's safety.

    Lighting equipment: Equipped with high-brightness working lamps, it is easy for the operator to load and unload and measure the workpieces.

    The working lamps are dust-proof, water-proof and explosion-proof.

    When the working lamp fails, the parts can be obtained in the market, which is convenient for the maintenance work and service time.

    Air pressure and lubrication system: The air pressure unit and lubrication system adopt high-performance and high-quality components to ensure system reliability.

    The processing space is large, the interference area of the processing workpiece is small, and the configuration of the chip flushing system makes it easy to discharge chips.

    Ergonomic and space saving
 

Distance between operator and spindle:313-663mm.
Distance between operator and table center:488mm.
Opening size of front operating door:900mm.
