PURPOSE:To automatically polish a work highly precisely by detecting the inclination of a work face with a gap sensor of an abrasion head, controlling a table of the work, and controlling the abrasion contact pressure with an abrasion contact pressure detector. CONSTITUTION:Although heights h1-h3 of individual ridge lines 12 are unequal caused by the torsion of blades, a change of cross section shape, etc., the height H of the valley line 17 against the final finishing face 13 is nearly uniform, therefore the groove bottom face 15 is analogous to the final finishing face 13. In addition, the valley line 17 normally generates no dirft in the lengthy direction in relation to the rotary center line 19 of the blade. Paying attention to such a characteristic of sweep milling rough finishing surface, the axis B of a contact wheel 20 is set at right angle to the ridge line 12, on which the wheel 20 is fed along it as shown by an arrow A, then a cutter wheel does not enter the groove of a cutter mark, thus offering efficient polishing. Accordingly, an automatic polishing device is provided with a gap sensor of an abrasion head, a rotating means of a table, and an abrasion contact pressure detector, etc. |
