I.Use a rigid and precise machine and holder.
2.When machining carbon steels or hardened steels, using MQL(Minimum Quantity Lubrication / mist coolant) is recommended.
3.The above condition shows an approximate standard for contouring operation (side milling) with a low machining load. If abnormal cutting sounds, vibration or chattering occur depending on the machining shape, cutting amount, rigidity of the machine or work holding condition, etc., please adjust the speed, feed and the depth of cut.
4.Adjust the speed, feed rate, and depth of cut if chattering, vibration or abnormal
grinding sounds occur. 5.Helical or ramp milling is recommended during the approach of a Z cut. 6.Adjust the speed, feed rate, and the depth of the cut according to the shape of
the work, rigidity of the machine, and how the work is held. 7.When the workpiece requires precision shaping, re-running the end mill in the
identical tool path is recommended.
