Device for supplying and recovering minimal quantity lubricant in magnetic field-assisted abrasive grinding

A device for supplying and recovering a minimal quantity lubricant in a magnetic field-assisted abrasive grinding, comprising:

• a grinding wheel guard assembly, comprising a grinding wheel guard, a grinding wheel mounted inside the grinding wheel guard, and a wind deflector provided on an outside of the grinding wheel;
• a magnetic worktable mounted on a lower side of the grinding wheel guard, and a magnetic clamp provided on a surface of the magnetic worktable;
• a controllable magnetic field assembly, comprising a permanent magnet and a first guide rail mechanism mounted on a surface of a first side of the wind deflector, the permanent magnet is connected to the first guide rail mechanism to move in a circular direction along the grinding wheel;
• the permanent magnet is also connected to a recovering and filtering device;
• a controllable nozzle assembly, being connected to the wind deflector and located on an opposite side of the wind deflector with respect to the controllable magnetic field assembly, comprising a nozzle, being connected to a linear motion mechanism;
• and
• a controlling and monitoring assembly, comprising a vision camera disposed on the magnetic worktable for obtaining images of temperature and wear conditions of a machined surface of a workpiece;
• the vision camera is connected to a system control box.
