MACHINE FOR PROCESSING OF COMPLEX SURFACES BY HIGH-SPEED MILLING Russian patent published in 2015 - IPC B23Q1/25 B23Q5/02 

FIELD: technological processes.

SUBSTANCE: invention relates to metal working. In a machine for processing of complex surfaces by high-speed milling, comprising a stand, a cutting spindle with a spindle head, a slide for spindle movement, the stand is made as T-shaped and comprises two parts, at the same time on the first part of the stand oppositely to each other there are T-shaped posts fixed, between which there is the cutting spindle, the body of which is hingedly connected to elements of a parallel kinematics mechanism, which represents hinged-lever links, which provide for movement of the cutting spindle by two coordinates in the vertical plane, due to vertical movements of the slide, covering upper shelves of the T-shaped profile of the posts, besides, the slide move along the posts due to a screw-nut gear, at the same time hinged-lever links are connected hingedly to the slide, and to prevent ingress of chips at the elements of the parallel kinematics mechanism on the first part of the stand, along its perimeter, there is a jacket fixed, made in the form of the surface of the rectangular parallelepiped, covering the space of posts location with the cutting spindle, which comprises a driving electric motor and a spindle located coaxially with it for fixation of a tool, for instance, a cutter, and on the second part of the stand, located in the horizontal plane of the first part of the stand and perpendicular to it there is a support installed for movement in the horizontal plane of a table that serves to fix a stock of complex processed contour, at the same time the support moves along the guides, parallel to each other and rigidly fixed on the other part of the T-shaped form of the stand, perpendicularly to the vertical plane of movement of the cutting spindle, and on the support perpendicularly to the horizontal plane of its movement and with the possibility of rotation around its axis, there is a table installed for fixation of the stock.

EFFECT: simplified design with simultaneous achievement of high dynamic and precision characteristics, as well as reduction of metal intensity.
