Safety Precautions: Only professionals with electrician operating certificates should be allowed to install or repair electrical appliances.
Before starting the machine, check to ensure that the voltage and frequency on the motor nameplate match the power supply.
The power plug and socket of the machine tool should have tight contact pins, without any looseness or non-contact.
Avoid mistreating the wire, do not forcibly pull the power cord from the socket, and keep the wire away from high temperatures, grease, and sharp edges.
In case of a fault or abnormal sound, immediately unplug the machine, turn off the button switch on the left side of the spindle box, and then carry out an inspection and repair.
Do not leave the machine running unattended, always stop it after shutting it down before leaving. In the event of a power cut, press the red button, as the machine should never run without power.
Maintain a clean and tidy work area, free from dampness, mess, and poor lighting. Do not use machine tools in flammable or explosive places and keep children and visitors away from the machine to avoid any safety hazards.
Do not exceed the maximum cutting capacity of the machine tool to avoid any unsafe situations.
Wear appropriate clothing, avoid wearing loose clothing or jewelry, and secure long hair with a hairpin. Wear gloves and a hat to prevent any risk of entanglement with the machine.
Secure the workpiece during operation, do not hold it while manipulating the machine with both hands.
Keep the guide rail surface clean, and prevent sand and dust from entering and damaging it.
Do not operate the machine when tired, under the influence of alcohol, or while under the influence of anesthesia.
In case of damage to parts of the machine tool or accessories, do not make substitutions. Use only corresponding parts with the same performance.
If you are unable to use the product within one month of purchasing it, it is important to perform regular anti-rust treatment. The frequency of the treatment should be adjusted based on the local humidity levels.
It is recommended to regularly inspect the operation status for a period of one month. If the screw surface becomes contaminated with dust or metal shavings, clean it using kerosene and then apply lubricant.
It is crucial to maintain the ball screw with lubricating oil at all times.
Method of operation
To begin, find the diameter of the milling cutter. To grind an 8mm vertical mill, use an 8mm milling chuck and secure the cutter to the 50D sleeve.
Next, set the angle and adjust the milling cutter sleeve to about 4° (with the bottom angle of the milling cutter being between 2°-6°).
Start by grinding the bottom surface. For example, when grinding a 4-edge milling cutter, align the cutter with the grinding wheel. Complete the tool setting, then grind the bottom angle of the milling cutter. Finish grinding one edge, and then switch to another cutting edge to complete the grinding.
Next, grind the clearance angle at the center of the cutter. Swing the sleeve to about 10° and then grind the center clearance angle of each milling cutter.
Repeat the process for the second clearance angle.
Finally, grind the side edge of the milling cutter. Use the tip to apply pressure to the spiral groove of the milling cutter, align the grinding wheel, and move the sleeve to grind the spiral side edge of the cutter.
By following these steps on a universal tool grinder, you can keep your milling cutter in good condition and solve any milling problems.
