PURPOSE: To improve an operation rate by controlling a grinding wheel rising/ lowering means, a work clamping mechanism on a work loading table and a work loading table moving/turning means respectively according to a prescribed procedure.

CONSTITUTION: For example, in the case of carrying out cutting processing on a work W on a right work loading table 4 (hereinafter referred to as table), an automatic switch of an operation panel 16 is turned on. Thereby, tables 4 and 5 are moved in a left prescribed position by means of a cylinder 27. Next, the table 4 is turned by means of a turning cylinder 42, and an arm 46 is moved in the standby position by operating a cylinder 47 of a clamping mechanism 43. Here, an operator loads the work W on a loading stand 48 of the table 4 by means of a handling device 6. Next, the work W is clamped by operating the clamping mechanism 43. When a cutting part is set, a grinding wheel 37 of a grinding wheel cutter 3 is lowered, and carries out prescribed cutting. After the cutting is finished, the grinding wheel 37 is rised, and the table 4 is moved/turned and so on, and the next cutting is carried out.
