The radial and axial runout of the spindle should be controlled within ≤0.01mm to ensure the stability and precision of the milling cutter.
The fit between the spindle outer diameter and the cutter inner diameter should be appropriate—neither too tight nor too loose. If the spindle is worn, it should be replaced promptly to avoid affecting machining accuracy and tool life.
The flatness of the clamping plates on both sides should be controlled within ≤0.003mm. The clamping plates should be made of high-quality steel and hardened to HRC50°, with chamfered inner holes and ground flat surfaces. It is recommended to use 3.0~4.0mm thick scrap carbide milling cutter plates for modification, as they offer high hardness, wear resistance, and minimal deformation, along with excellent flatness. If needed, our company can provide assistance with clamping plate processing.
Clamping nuts should be replaced regularly to prevent increased thread clearance over time, which can cause cutter misalignment and affect machining accuracy.
The feed rate should be moderate, and the cutting speed should be consistent to avoid overloading or damaging the tool, while ensuring good surface finish.
Cooling should be sufficient, and it is recommended to use 45# mechanical oil as the coolant to effectively reduce cutting temperature, extend tool life, and improve machining quality.
