CUTTING METHOD

Japanese Patent JP2015139860

A

PROBLEM TO BE SOLVED: To provide a cutting method capable of reducing a fear of the adhesion of cutting chips to work, and suppressing the generation of chipping on the work.SOLUTION: On a blade cover 13 provided on a cutting device 1 used for a cutting method, a discharge port 136 communicating with a slit-shaped opening portion 132 and connected to a suction source 14 is formed. Therefore, if a cutting step is executed, a cutting liquid 155 including cutting chips can be discharged to the outside from the discharge port 136, and a fear of adhesion of the cutting chips on an upper surface of work W can be reduced. In the cutting step, the suction source 14 is actuated, and even if negative pressure is generated in cavities 17a and 17b formed around the slit-shaped opening portion by being surrounded by the cutting liquid 155 supplied to an upper surface Wa of the work W and the work W is floated, the pressurized cutting liquid 155 is supplied on the upper surface Wa of the work W, so that the floating of the work W is suppressed, and the generation of chipping on the work W can be suppressed.
