FIELD: mechanical engineering; devices and methods for separation of materials.
SUBSTANCE: the invention is pertaining to the device and the method for separation of materials, in particular, to monocrystals. The technical result of the invention is effective purification and removal of the stripped material during the cutting. For this purpose the device contains: a rotary cutter with a concentric hole, the edge of which forms the cutting edge, at that the rotary cutter is made with a capability of rotation around its central shaft for cutting of the material; a position device intended for positioning of the material subjected to cutting in respect to the rotary cutter in such a manner, that during the cutting process the cutting disk is moving across the material making rotation for cutting-off a separate plate; a device for feeding a lubricating-cooling liquid onto the rotary cutting disk and a device for feeding a gaseous medium onto the rotary cutting disk. At that the device for feeding the gaseous medium has a nozzle, which is mounted inside the concentric hole and is designed in such a manner, that the gaseous medium is fed onto the edge in the direction perpendicular to central shaft of the rotary cutting disk. The method provides for feeding of the lubricating-cooling liquid only onto the outlet side of the cutting disk if to look in the direction of its rotation behind the place of the rotary cutting disk pass through the material. At that the rotary cutting disk is subjected to cooling during operation of the cutting, and the plate is cooled only after operation of the cutting after the separate plate has been cut off during operation of the cutting. At that during the cooling operation the lubricant-cooling liquid is fed by the batching amounts, and during the stripping operation the lubricant-cooling liquid is fed in the bigger amount as compared with the indicated above amount.
EFFECT: the invention ensures the effective purification and removal of the stripped material during the cutting operation.
