The cooling nozzle 107 sprays a mixture of high-pressure gas and atomized cooling oil to cool the tool and the grinding wheel. After spraying, the debris drips into the recovery unit with the cooling oil, and the cooling oil is recovered by the recovery unit for secondary use.

[0035] In this embodiment, the debris in the cooling oil is gradually filtered through multiple groups of the filter components, and the filter apertures of the multiple groups of the filter components become smaller from top to bottom, so that the debris content of the cooling oil that finally flows into the recovery collection box is reduced.

The power interface 121 is used to connect the electromagnetic component to an external power source to power the electromagnetic component. When the electromagnetic component is energized, electromagnetic force is generated, so that metal debris is tightly adsorbed on the magnetic plate 120, which makes it more convenient and quick to recover the cooling oil.

[0044] Furthermore, each group of the electromagnetic components includes an insulating tube 122, a power-carrying coil 123 and a magnetic column 124, one end of the magnetic column 124 is embedded in the insulating tube 122, and the magnetic column 124 covers the insulating tube 122, the power-carrying coil 123 is embedded in the insulating tube 122, and the power-carrying coil 123 is sleeved on the outer wall of the magnetic column 124.

[0046] See also Figure 6 The present invention also provides a high-precision hard material tool grinding method, which is applied to the high-precision hard material tool grinding device as described above, and comprises the following steps:

[0047] S1: installing the tool to be processed on the clamping mechanism 102 for clamping and fixing, and adjusting the position of the cooling nozzle 107 so that the cooling nozzle 107 is located within the tool safety range;

[0048] S2: Then the grinding mechanism 101 is started to grind the clamped tool;

[0049] S3: During the grinding process, the tool simultaneously pumps cooling oil into the liquid inlet pipe 105 and pumps high-pressure gas into the air inlet pipe 106;

[0050] S4: The cooling oil and the high-pressure gas enter the mixing chamber 104 together for mixing and pressurization, and are finally sprayed out through the cooling nozzle 107 to cool the surface of the tool and the grinding wheel;

[0051] S5: The cooling oil and the adhered grinding chips drip onto the frame and are recovered by the recovery unit for secondary use.

[0052] In the present method, cooling oil is sprayed on the grinding wheel and the tool during the grinding process, which can effectively play a cooling role. At the same time, the mixture of high-pressure gas and cooling oil can improve the cooling efficiency and reduce the use of cooling oil. The recovery through the recovery unit can further reduce the processing cost. The cooling oil can effectively absorb the heat generated during the grinding process, reduce the temperature of the grinding zone, prevent the tool and the workpiece from thermal deformation due to high temperature, and help maintain the dimensional accuracy of the workpiece and the cutting performance of the tool. The lubricating effect of the cooling oil can reduce the friction between the tool and the workpiece, reduce the generation of grinding force and frictional heat, not only prolong the service life of the tool, but also reduce the wear and chipping of the tool.
