Guide for ramping (Slant milling)

L Ramping angle should be RMPX (Maximum ramping angle) or under in the above cutting conditions. Feed rate should be 70% or undear of the above cutting conditions.

Formula of the cutting length ap RMPX

L = “L” at max. ramping angle tan RMPX ap

Guide for helical milling

For helical milling, use between min. cutting dia. and max. cutting dia. øDh (Machining dia.) Over max. cutting dia. Under min. cutting dia. Cutting direction Center core part remains Center core part interferes after machining with toolholder

M

DCX (Cutting dia.)

Description Min. cutting dia. Max. cutting dia. Sinking depth at helical milling should be max. ap (1mm) or under.

  • Down-cut milling is recommended. (refer to the figure above)

MFH...-03-... 2×DCX-8 2×DCX-2 Feed rate should be under 50% of the recommended cutting conditions.

  • Be careful to machine in a safe environment to avoid accident caused by long chips.
