Provided is a machining tool in which the effort in exchanging a ball screw can be alleviated. A machining tool (1) is provided with: a base 5; a moving body 6; a ball screw 7 having a nut 7n and a screw shaft 7s; a cap member 8 that covers an end 72 of the screw shaft 7s and allows rotation of the screw shaft 7s about the center line AX0; and a support part 9 that is provided to the base 5 so as to support the cap member 8. The cap member 8 includes: a body section 81; and a flange section 85 that is disposed at the outer side D1o, in the axis direction D1, from the body section 81 and that is wider than the body section 81. The support part 9 includes: a recess 95 in which an opening 96 for passing the screw shaft 7s in a direction D2 orthogonal to the axis direction D1 in the state where the support part 9 is provided to the base 5, is provided to receive the body section 81; and a positioning section 91 on which an inner surface 86 of the flange section 85 abuts in the axis direction ...
