PROBLEM TO BE SOLVED: To easily adjust a pair of cooling water nozzles at an optimal position to a cutting blade.SOLUTION: A nozzle adjusting jig (8) is mounted to a stationary flange (332) mounted to a tip of a spindle (31) instead of a cutting blade (34), so as to adjust front and rear positions of a pair of cooling water nozzles (71) arranged to sandwich the cutting blade (34). The nozzle adjusting jig (8) is mounted to a support face (333) of the stationary flange (332) by a magnetic force, and the cooling water nozzle (71) positioned in front of the cutting blade (34) is brought into contact with the nozzle adjusting jig (8), so as to properly adjust the front and rear positions of the pair of cooling water nozzles (71) to the cutting blade (34). |
