How to use end mills for shoulder milling?

What is shoulder milling?

Shoulder milling processes two surfaces at the same time, which requires the combination of circumferential milling and surface milling. Machining a true 90 ° shoulder is one of the most important requirements. Traditional shoulder milling, vertical milling, long edge milling and three face milling can be used for shoulder milling. Because there are many options, the requirements of the process must be carefully considered in order to make an appropriate choice.

Milling cutter selection:

Traditionally designed shoulder milling cutters can usually mill real 90 degree shallow shoulders. Many shoulder milling cutters are universal milling cutters, which can be conveniently used for hole machining. When milling a vertical face or near a vertical face, they are ideal alternatives to face milling cutters.

  • End milling cutter: Indexable inserts and integral carbide end mills provide an ideal solution for square shoulder machining requiring accessibility.
  • Long edge milling cutter: Long edge milling cutters are usually used to mill deep square shoulders.

How to apply square shoulder milling?

  • Shallow shoulder milling: This common process is usually performed by shoulder and end mills. Small cutting depth can achieve larger cutting width. These milling cutters can usually replace face milling cutters, especially when the axial pressure for parts becomes a limiting condition, and when there are requirements for the accessibility of vertical surfaces or fixtures. The large size of shoulder milling cutter can ensure good accessibility when it is located at the deep shallow shoulder.
  • Deep square shoulder milling: Repeat with shoulder milling cutter and end milling cutter. In order to minimize surface tools, such as blade overlap and double tool overlap, it is important to use high-precision tools that can process a true 90 ° shoulder. If the shoulder depth is less than 75% of the cutting edge length, the quality of the vertical surface usually does not need to be finished.
