Described sensor block comprises sensor block and following sensor block, and described sensor block detecting element comprises the last sensor block detecting element that detects upward sensor block vertical direction displacement and detects the following sensor block detecting element of sensor block vertical direction displacement down; The described sensor block of going up is fixed on the tappet with following sensor block, and last sensor block detecting element and following sensor block detecting element are fixed on the cutter shaft of vertical direction.
Last sensor block and following sensor block can detect the deflection of processing work in the in the vertical direction distortion downwards and the distortion that makes progress respectively; For the high umbilicate distortion in two of longaxones parts, processing parts can be processed punishing into two sections in minimum point at least, just can detect for these two sections that are divided into by different sensor blocks.
Described position of going up sensor block can be higher than sensor block down, and like this, last sensor block detecting element promptly is lower than the position of going up sensor block, and following sensor block detecting element promptly is higher than the position of sensor block down.
Described detecting element can adopt near switch, perhaps adopts infrared ray distance detecting element accurately to detect.
Beneficial effect: a kind of numerically-controlled machine provided by the invention follow job operation automatically, when the processing longaxones parts, can cancel and follow workpiece support mechanism, avoid to guarantee requirement on machining accuracy owing to follow the problem that is caused when the support of workpiece support mechanism changes.
