TURNING AND BROACHING MACHINE WITH BALANCE MEASUREMENT FUNCTION

摘要

PROBLEM TO BE SOLVED: To provide a turning and broaching machine with a balance measurement function which can reduce the number of defective components.SOLUTION: A turning and broaching machine 103 comprises first and second encoders 38, 48, first and second oscillation sensors 39, 49, and a controller 80. The first and second encoders 38, 48 detect phases of a material crank shaft 1 centered on a rotation axis AX during a rotation of the material crank shaft 1 and output phase data indicative of a detected phase. The first and second oscillation sensors 39, 49 detect an oscillation of the material crank shaft 1 in a radial direction during a rotation of the material crank shaft 1 and output oscillation data indicative of a detected oscillation. The controller 80 calculates a rotational unbalance amount of the material crank shaft 1 on the basis of the phase data and the oscillation data.
