PURPOSE: A bore hole processing apparatus of a cylinder block for a vehicle is provided to prevent the abrasion due to the piston motion by steadily the oil pocket processing mounted on a bore hole of the cylinder block. CONSTITUTION: A bore hole processing apparatus of a cylinder block for a vehicle comprises laser oscillator(100), a beam splitter(200), a spindle adjusting unit(300) and a laser beam irradiation part(400). The laser oscillator generates the laser of the different kinds. The beam splitter divides the laser beam so that the laser from the laser oscillator is emitted to the each bore hole mounted on the cylinder blocks. The spindle adjusting unit rotates in the cylinder bore inside and is connected to the lower part of the beam splitter. The laser beam irradiation part is included in the end part of the spindle adjusting unit. The laser oscillator comprises a first laser(110) and a second laser(120). |
