A machining system having plural machining devices installed at plural points in a robot arm. the machining system carrying out machining to a processed object made of metal be by using these machining devices, the machining system further having a control device that controls drive of the machining devices so as to offset processing reaction forces by at least one of a thrust force and a torque to be obtained when the machining devices carry out machining to the processed object simultaneously between the machining devices.

The invention relates to a device (1) for drilling holes in the axial and radial direction of a blade root of a wind turbine, wherein the device comprises: a first base (2), which is to be stationary positioned on the ground; a second base (3), which is moveably mounted to the first base (2) and movable along a first direction; first drive means for positioning the second base (3) along the first direction; a rotary arm (4), which is pivotally mounted to the second base (3) around a main axis (5); second drive means for rotating the rotary arm (4) around the main axis (5); wherein the rotary arm (4) comprises a guide track (7) which extends from a first outer end to a second outer end of the rotary arm (4) thereby passing the main axis (5); first drilling means (8) moveably arranged on the guide track (7), comprising a first drilling tool (8-1) for drilling holes in a second direction (8-2), which second direction (8-2) is perpendicular to the main axis (5) andthird drive means for positioning the first drilling means (8) along the guide track (7); second drilling means (9) mounted on the rotary arm (4), comprising a second drilling tool for drilling holes in a third direction (9-2), which third direction (9-2) is parallel to the main axis (5).

A wheel bolt hole chamfer device is composed of a base, a support frame, a lower servo motor, a turntable, stop blocks, guide rails, strong springs, a driving friction wheel, driven shafts, driven friction wheels, chamfer cutters and the like. The device can be put into a production line as a fourth-procedure machining device, and bolt hole chamfers are no longer machined in three procedures, so that the three-procedure machining time is reduced; and after the fourth procedure for machining the bolt hole chamfers is supplemented, the machining time of a single wheel is shortened, and the efficiency is improved. The device integrates pitch diameter adjustment and rotating drive of the chamfer cutters, so that a drive system and a power system are greatly simplified, i.e., the manufacturing cost of the device is reduced, all bolt hole chamfers can be machined at the same time.
