Square shoulder milling nose tool

The maximum depth of cut (DOC) should be less than or equal to 10% of the diameter of the ball.

Stepover should be greater than or equal to DOC.

The nose tool is not designed for rough machining. The use of high speed machining (optical DOC and high feed rate) for stable and rapid cutting requires more metal removal.

Shunmill is preferred.

When using a bulb, use the maximum pecking cycle. 002; The maximum recommended depth is 30% of the diameter of the ball.

Pad design of floor and bottom board is not used for falling; Slope in maximum 2 ° Angle.

Effective cutting diameter compensation (see table/chart below).

Compensation chip reduced feed rate adjustment (see table below).

Surface finish (RMS) is a function of the meat stew and feed for each tooth.

Try working on the recommended surface video and chip load.

Reduce the feed rate to reduce the flutter.

For long – term use, the core cutting tools of hard alloy shank/hard alloy are used to increase hardness and reduce flutter.

Application information

Technical factors

Use the anti-robbery compound regularly on screws.

Thoroughly clean every insert replacement pocket.

Insert screws for every 10 inserts.

Use short length knife rack (end milling cutter) to achieve maximum hardness. The cutting tool shank shall be as upward as possible in the spindle cone of the machine.

Use a tool holder for rough handling: use end mills and power clamps; There is a seam jacket not recommended.


Square shoulder milling allows for heavy cutting depth (DOC), but DPA recommends no more than 2/3 insertion length to reduce the chance of screw breakage.

Although the cutter has a heavy cutting ability, it also takes into account the power and stiffness of the machine tool.

Use cutting edge (DOC) as much as possible to get the most metal cutting in the life of the insert tool

The feed rate should not be significantly lower than the recommended range (see below) or fail prematurely.
