MATERIALS MECHANICAL PROCESSING DEVICE AND METHOD BY MILLING AND DRILLING Russian patent published in 2017 - IPC E21C27/24 E21C25/10 E21C35/24 

FIELD: technological processes.

SUBSTANCE: group of inventions relates to materials mechanical processing method and device by milling and/or drilling, particularly for removal of hard rocks, concrete, minerals or coal. Device includes tool drum accommodating several tool shafts with machining tools attached to their ends, projecting from tool drum. At that, tool shafts can be driven into rotation. Tool shafts driving element and tool drum can rotate relative to each other, wherein drum carrying device can displace relative to material using displacement device. Using control device tool carrying device displacement speed can vary relative to material and tool drum speed. To avoid occurrence of critical operating conditions device is equipped with, at least one measurement transducer for measurement of natural translational vibration and/or, at least one measurement transducer for determining tool drum angular oscillations, and control device, which contains at least one vibrations analyzing module, using which vibrations range can be defined during analysis of oscillations, and at least one controller module, using which rotation speed and/or relative speed are controlled or adjusted as oscillations function defined by analysis module. Method of materials machining by means of device.

EFFECT: improving mechanical processing device.
