4CH_CUT

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.

Fig. 1: Mechanism of burring generation (seen from the side)

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

	1. 0º⇒90º (CH1⇒CH2)
		When separating into die, burring is generated in the direction of blade rotation.

Fig. 2: CH1⇒CH2

	2. 0º (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.

Fig. 3: CH3

	3. 270º (CH4)
		In CH2, cut lines are cut again in the direction of the red arrows shown in fig. 4, and burring is cleared away.
