Maximum Cutting Depths
For safe and efficient operation, adhere to the following maximum cutting depths:
For ae ≤ 3.0mm: ap = 0.15D for materials up to HRC30, increasing to ap = 0.25D for harder materials (HRC50-65).
For ae > 3.0mm: ap = 0.25D for materials up to HRC30, increasing to ap = 0.05D for harder materials (HRC50-65).
Usage Recommendations
Initial Use: Begin with 50% of the recommended cutting speeds and feed rates for trial cuts. Gradually increase these once the cutting conditions are stable.
Tool Holding: Utilize high-precision, high-stiffness tool holders with good dynamic balance. If tool runout exceeds 0.01mm, improve the setup before proceeding with cutting.
