Processing device

Provided is a machining device capable of accurately adjusting the inter-axial distance between a first rotating tool and a second rotating tool. A processing device (2) is provided with: a mounting table (3) capable of moving in a first direction (X); a moving member (6) capable of moving in the second direction (Y); a first machining unit (S1) having a first spindle (7) that rotatably supports a first rotary tool (8); and a second processing unit (S2) having a second main shaft (7) for rotatably supporting a second rotary tool (8), and a support device (9) for supporting the second main shaft (7) so as to be adjustable in position in the first direction (X) and the second direction (Y). The support device (9) has: a fixed part (9c); a support section (40) that is supported so as to be rotatable about a first rotation axis (12b) extending in a third direction (Z) with respect to the fixed section (9c), and that supports the second main shaft (7); and a first operation section (31) that rotates the support se
