MACHINE WITH PARALLEL KINEMATICS OF INCREASED VIBRATION RESISTANCE Russian patent published in 2021 - IPC B23P23/02 B23Q5/04 

FIELD: machine building.

SUBSTANCE: invention can be used in designing base parts of machines for high-speed processing of parts. Machine comprises a base, three racks, slides installed with possibility of movement along vertical guides of posts, spindle motor with tool, located in spindle head body, three pairs of rods, which are fixed in pairs by one ends by means of universal hinges on slides with formation of parallelograms, table for installation of processed part. Spindle head housing is equipped with metal and polymer concrete slabs alternating in lengthwise direction installed around it, wherein metal plates have through holes and grooves filled with polymer concrete, and other ends of said pairs of rods by means of universal hinges are fixed on plates from metal.

EFFECT: use of the invention increases vibration resistance of the housing of the spindle head and the machine as a whole.
