4CH_CUT

Application processing examples

4CH_CUT is an effective cutting method to decrease the burr generated when cutting a resin substrate.

Mechanism of burring generation

When a resin substrate is cut, burring is generated in the direction of the blade rotation.

4CH_CUT Method (All the processes are by down cut)

  1. 0°⇒90° (CH1⇒CH2)

    When separating into die, burring is generated in the direction of blade rotation.

    CH1→CH2
    Fig.2 CH1→CH2
  2. 0° (CH3)

    In CH1, cut lines are cut again in the direction of the red arrows and burring moves in the direction shown in Fig. 3.

    CH3
    Fig.3 CH3
  3. 270° (CH4)

    In CH2, cut lines are cut again in the direction of the red arrows shown in fig. 4, and burring is cleared away.
