Tooling applications

Milling of aluminum components

Cutter weight and insert comparison

The HFC cutter weighs approximately half as much as competing products on the market. 
A 125mm 4.921” cutter with BT30 arbor* has a total weight of 2kg 4.4 lbs or less.
This lightweight design allows 125mm 4.921” cutter to be used even on compact machine.
* Using a BT30-FMNA25.4-40 ( 0.7kg 1.54 lbs )

Safety clamp mechanism

Unique pocket design uses a wedge shape and centrifugal forces to help prevent the insert from sliding out.

Insert regrinding capability
  • Inserts can be reground up to four times.
  • Each regrind reduces the insert width and height by 0.1mm .004” from the previous condition.
  • A star marking indicates the number of completed regrinds.

*The number of re-grinds per insert may vary depending upon cutting edge damage evaluation.

Process

  • Loosen the axial adjustment screw
  • Install inserts (lightly hand tighten)
  • Clean the inserts
  • Adjust height of inserts (initial setup)
  • Tighten wedge set screw (firmly tighten)
