What Are The Precautions For Using Carbide Milling Cutter?

Today Qianchui Tool will share with you what aspects of Carbide Milling Cutter should be paid attention to when using it. We will talk about installation and maintenance, parameter adjustment, and safe use specifications.

Installation and maintenance

‌We need to pay attention to the installation accuracy, ensure that the blade is aligned with the spindle, radial runout ≤0.02mm, axial runout ≤0.01mm, and preferably use large-size flanges (not less than 1/3 of the blade diameter) to clamp to reduce vibration. It should be noted that people need to thoroughly clean the blade and mechanical mounting surface before installation to avoid uneven force caused by residues, leaving safety hazards. After operation, it is necessary to carry out rust prevention treatment in time, avoid collision on the cutting edge, and keep it dry during storage to avoid oxidation. ‌

Cutting parameter adjustment

‌Before use, people need to adjust the speed and feed operation according to the material characteristics. The processing speed of softwood is 60-90 m/s, and that of hardwood is 50-70 m/s; the recommended helix angle for stainless steel is 40° (speed × 1.0, feed × 0.8), and the same is true for titanium alloy, but the speed needs to be reduced to about 70%. In addition, you need to feed at a constant speed to avoid sudden acceleration or pauses. Keeping a constant feed speed during normal cutting can prevent tooth breakage or knife hitting. ‌

Daily maintenance

‌For Carbide Milling Cutter, we need to pay attention to regular inspections, use of cooling systems, and attention to tool wear and replacement.

This product needs to idle for 2 minutes before operation to observe whether there is any abnormal vibration or sound; we also need to cooperate with high-pressure cooling (such as oil mist cooling) during processing to avoid overheating of the blade. ‌In addition, the tool should be replaced in time after passivation to avoid overload operation and increase the loss by more than 30%. ‌

Safety regulations

‌In terms of safety, it is recommended that people use protective devices. Carbide Milling Cutter must be equipped with a protective cover when running at high speed to prevent debris from splashing and injuring people. In addition, attention should be paid to operating regulations. It is forbidden to directly touch the rotating blade with your hands, and the machine should be stopped when changing the cutter. ‌
