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.

   

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.

   

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.
