DEVICE FOR ABRASIVE-CUTTING DISC COOLING, CLEANING AND STABILIZING Russian patent published in 2004 - IPC

FIELD: cutting technique by abrasive-cutting discs, cooling, cleaning and stabilizing equipment. SUBSTANCE: abrasive-cutting discs are installed in case including two fixedly connected sidepieces. Cavities for lubrication-cooling fluid or air feeding under pressure are made on sidepiece inner surfaces. Cavities are arranged around concentric circles and formed as voids of hydro(aero)static guides. Hydro(aero)static guides are open. Hydro(aero)static guides are connected with lubrication-cooling fluid and air sources by adaptive control system. Control system comprises execution unit and feedback sensors, which connect in pairs to case sidepiece concentrically to hydro(aero)static guides. EFFECT: enhanced disc stability due to provision of pressure difference on sides of abrasive-cutting disc deviated from cutting plane, which is carried out by lubrication-cooling fluid or air flow rate change. 5 dwg
