Automatic CNC milling machine is used for mold making and 3D milling works, including metal molds, clock parts, metal electrode, shoe molds, metal arts and crafts, jewelry and other molds making, the CNC mill can make 2D or 3D relief on various materials.
A CNC milling machine is an automatic computer-controlled manufacturing tool, working with programmed instructions, using a milling cutter to remove excess from a workpiece, resulting in precise shapes with high repeatability.
CNC milling machines are extremely popular for precision machining of most materials, including metals, wood, and composites, allowing complex designs and high-tolerance parts to be created with an automated process.
CNC mills are typically used in mold making, prototyping, making parts for aerospace, automotive industries, electronics, medical devices, and custom tooling along with fixtures. What gives them a critical standing within modern manufacturing workflows is that they can perform various functions, including cutting, engraving, tapping, grooving, milling, drilling, tapping, and surface finishing.

CNC milling machine is a high-precision and high-efficiency machining equipment. Regular maintenance is important to keep its accuracy and extend its service life.
1. Dust Cleanup: Use soft cloth and detergent to clean the surface of the engraving and milling machine equipment, keep the appearance of the equipment neat, and prevent dust and debris from entering the equipment.
2. Parts Maintenance: Regularly check the various parts of the engraving and milling machine, including guide rails, transmission systems, spindles, fixtures, etc., to ensure that they operate normally, and find and solve problems in time.
3. Lubrication Maintenance: Lubricate the various parts of the engraving and milling machine according to the requirements of the equipment manual to ensure the friction coefficient and operation efficiency between the parts of the equipment.
4. Temperature Control: Regularly check the working temperature of the engraving and milling machine to avoid excessive temperature affecting the normal operation of the equipment, and deal with abnormal temperature problems in time.
5. Cooling System Maintenance: The cooling system must be used during the engraving and milling process to ensure the heat dissipation of the spindle and tool, reduce tool wear and extend the life of the equipment.
6. Regular Calibration: Calibrate the machine regularly to ensure the processing accuracy and stability of the equipment.
7. Safety Protection: Ensure that the safety protection facilities around the machine are intact to ensure the safety of the operator and avoid accidents.

So far this automatic milling machine is as good as I expected and serves its purpose in my gunsmith shop to repair, design, modify, or build guns. Sturdy enough with its structure for metal fabrication. If you take the time to learn the CNC controller software, the mill table will be easy to use and provide excellent quality works. In addition, there are some upgrade kits to bring it to the next level. I recommend ST7090-2F for the price and quality.
