Features of China CNC Drilling And Milling Machine

• The Z-axis structure is the point of this CNC mill drill machine. Unlike some similar equipment with two linear rails on their Z axes, the spindle box utilizes an embracing design and it’s Z-axis is equipped with four 45mm roller linear guideways. This design brings the machine some improvements and several benefits, such as heavy-duty load capacity, high motion rigidity, excellent positioning accuracy, and great machining stability.

• The milling spindle is driven by a transmission mechanism consisting AC servo motors and ball screws. Furthermore, it has functions of automatic tool loosening, pneumatic and hydraulic compound loosening, and disc spring tensioning.

• The mechanical spindle is directly connected to the servo motor by a timing belt, allowing the spindle to tackle orientation and rigid tapping functions. The mechanism of a dedicated AC servo motor driving the spindle rotation via a belt is very helpful for increasing its torque.

• A Japanese six-row bearing is placed inside the spindle; however, there are four in the front and two at the back. This angular contact bearing set ensures that spindle speed changes uniformly and steadily. Alongside the BT50 tool taper, it also features an Italian rotary joint— allowing the machine to attain center water discharge. The enigmatic U-drill high-speed drilling would not be possible without these components.

•The CNC drilling milling machine operation is made faster and easier with the spindle tool changer and the rotating tool magazine.

•The double nitrogen balance cylinder motion is operated by a separate air pressure system. A more special design than ordinary cylinders, this type of cylinder can assist us in balancing out any unbalanced force that occurs during machine operation. It aids in reducing wear as well as no-load torque; this contributes to assuring the precision and stability of ball screw since it eliminates any effect coming from other external factors, other than what is needed for the intended operation.

• Through the spiral chip grooves on both sides of the bed, coolant flows into the chain plate elevator at the rear of the CNC drill mill.

• The Coolant is filtered and separated, then transported to the cooling nozzle on the spindle via an electric pump after flowing into the coolant tank on the elevator.

• Using CNC technology, a handheld unit with a USB interface and LCD display is combined with a centralized control box. Programming, storage, display, and communication are all made easier with the operation interface's functions such as dialogs between humans and computers, error compensation, and automatic alarms.

• Breakpoint memory function. If a sudden power outage or other reason stops the operation, the operator can quickly and easily locate the position of the last hole drilled before the power outage, and proceed to the next operation without delay.

• The system lets the operator control both the chip breaking time and cycle, therefore enabling different purposes for chip breaking.

• The operator just has to indicate the interval of time separating two oiling runs. The oiler will start running on its own once the predetermined time has passed. An automatic oiler lubricates every transmission component automatically, therefore lowering friction resistance and extending the service life of the drill mill CNC machine.

• Both internal and external cooling systems are included into this machine. While light milling processes require exterior cooling, high-speed drilling calls for internal cooling.

• Simple operation of the fixture consists simply a pressure plate, a push rod, a pull rod, and a pad securing the workpiece.

Application of CNC Drill Mill

Applicable Field

The machine is ideal for drilling holes and milling operations into metal elements such as flat plates, wind power flanges, discs, and rings.

Applicable Materials

Any kind of metal.

Design Features of The Mechanical Part

• HT250 cast iron makes up every casting component and element in this machine.

• The base, worktable, column, beam, ram and other pieces make up the machine mostly. And they are all constructed using resin sand molding and high-strength cast iron. This promise the machine has good shock absorption, thermal stability, and great general structural strength and rigidity.

• The three axes—X, Y, and Z—use a ball screw plus a servo motor for transmission;

• The base and beam are directed by linear guides; and the spindle is powered by four linear guides, thereby forming an encompassing structure.

Operating Environment for CNC Drilling Milling Machine

• Precision machining depends on a steady ambient temperature being maintained, the machine's appropriate operating temperature range is -10℃～35℃.

• Equipped with a voltage stabilizer to guarantee steady voltage in the machine working region.

• The mill drill CNC should feature a safe grounding; The grounding wire need to be copper wire with a resistance of at least 4 ohms and a diameter more than 10mm².

• To avoid machine tools failure or loss of precision, kindly keep the equipment away from direct sunlight, vibration sources, heat sources, high-frequency generators and electric welders. 

Quality Inspection of China Best CNC Milling Drilling Tapping Machine Center

• Every EagleTec CNC milling drilling machine is precisely tested and compensated for pitch error, backlash, positioning accuracy, and repetition positioning accuracy by means of the British RENISHAW laser interferometer. This mechanism guarantees both machine processing accuracy and dynamic and stationary stability.

• All our cnc milling machine has to be ballbar tested. This test will evaluate the three-dimensional machining accuracy and roundness of the machine by calibrating its geometry and roundness using a ballbar from the UK business RENISHAW and doing arc cutting tests.

Required Preparation Work Before Receiving the Drill Mill CNC Machines

Foundation Preparation:

• Please engage a professional design institution to modify the foundation construction plans depending on the actual soil conditions based on the foundation drawings given by the machine manufacturer before starting the manufacturing of the plant.

• Please ensure that the foundation is built according to the professional foundation construction drawings. The foundation should be made of solid, rigid and smooth concrete that meets all the requirements specified in the manufacturer's foundation drawings. After the foundation is laid and the concrete is completely solidified, the CNC mill drill machines can be installed.

Power Cord and Ground Wire Preparation:

Before formally installing the equipment, please prepare the power cord from the main power supply of the factory to the machine cabinet and the ground wire from the electrical cabinet to a separate grounding point. The ground wire part requires separate grounding.

Tool Hoist Preparation:

Opening tools, lifting equipment, and lifting ropes

Q & A

Q: Does the machine have the function of automatically focusing the center?

A: When processing a circular flange workpiece, it can be placed at any position on the workbench. The edge finder installed in the spindle taper hole measures any three points on the workpiece (inner diameter or outer diameter) and then aligns it. The center position is automatically calculated by the CNC program, which is accurate and fast.
