PURPOSE:To carry out measurement over a wide range from upper to lower ends, expedite the determination of correcting quantity and improve productivity by providing plural air microsensor nozzles on the upper and lower parts of a bone head and measuring dimensions. CONSTITUTION:Plural air microsensor nozzles 8, 9 of a dimension detecting part are provided upper and lower parts of a hone head 2 to measure the dimension of a workpiece 3. Thereby, the dimension of the workpiece 3 can be measured over the wide range from the upper to lower end parts, enabling the accurate detection of a bore form and improving correcting accuracy. And, the measurement can be immediately carried out without need for drawing up the hone head 2 at the same time a machining cycle is suspended. Further, the workpiece 3 can be measured symultaneously in plural places in the vertical direction, instantly detecting the difference in dimensions and, thereby, expediting the determination of correcting quantity while reducing the cycle time of honing and improving productivity. |
