Embodiment 1

[0027] Raw materials and weight percentages are as follows:

[0028] Polyethylene glycol 1~10%

[0029] Triethanolamine 1~9%

[0030] Industrial glycerin 1~10%

[0031] Castor oil triethanolamine 1~4%

[0032] Boric acid 1~15%

[0033] Sodium nitrite 1~16%

[0034] Potassium tripolyphosphate 1~4%

[0035] Potassium hydroxide 1~12%

[0036] Sodium Benzoate 1~3%

[0037] Sodium thiosulfate 1~ 2%

[0038] Isothiazolinone 0.3~1.3%

[0039] water balance.

[0040] Each raw material can be selected within the weight range, so that the weight sum is 100%.

[0041] The production method is as follows: add the calculated and weighed water into the oil reaction kettle, start the agitator, control the speed at 80 rpm, and then add the calculated and weighed potassium hydroxide, potassium tripolyphosphate, sodium benzoate, and sodium nitrite , sodium thiosulfate, boric acid and other solids were gradually added to the reaction kettle in turn, and stirred while adding until it w...

Embodiment 2

[0043] Production method is the same as embodiment 1, but raw material and percentage by weight are as follows:

[0044] Polyethylene glycol 5%

[0045] Triethanolamine 4%

[0046] Industrial glycerin 5%

[0047] Castor Oil Triethanolamine 2%

[0048] Boric acid 7%

[0049] Sodium nitrite 8%

[0050] Potassium tripolyphosphate 3%

[0051] Potassium hydroxide 6%

[0052] Sodium Benzoate 2%

[0053] Sodium Thiosulfate 1%

[0054] Isothiazolinone 0.8%

[0055] water balance.

[0056] The products of Example 1 and Example 2 of the present invention are used to prepare working fluid at 4-6%, put into the grinding fluid tank of the machine tool, and use the pumping circulation spraying method for grinding. Applied to the grinding of bearing steel, the grinding temperature and grinding force can be minimized, the grinding efficiency, the grinding accuracy and surface quality of the workpiece can be improved, and the service life of the grinding wheel can be extended.

Description

technical field [0001] The invention relates to a grinding fluid for metal grinding, in particular to a grinding fluid which can reduce the grinding temperature and grinding force to the greatest extent, improve the grinding efficiency, ensure the grinding accuracy and surface quality of the workpiece and extend the length of the grinding wheel. A bearing steel grinding fluid and a production method that have a long service life, reduce costs, and meet environmental protection requirements. Background technique [0002] Grinding is a processing method that uses the high-speed rotation of the grinding wheel to cut the workpiece. During the grinding process, due to a large number of deformations and new friction surfaces, and the grinding wheel also bears huge impact and vibration during the processing, Therefore, there will be problems such as reduced durability of the grinding wheel, rough machined surface of the workpiece, and poor dimensional accuracy. Therefore, during t...
