example 1

[0045] Select the bonding mixed abrasive of the following ratio, and its ratio by weight percentage is:

[0046] 24# brown corundum abrasive 40%

[0047] 30# brown corundum abrasive 37%

[0048] Phenolic resin solution 5%

[0049] 240 mesh phenolic resin powder 10%

[0050] 120 mesh ice crystal 7%

[0051] PTFE powder (average particle size 5μm) 1%

[0052] Its preparation process is as follows:

[0053] Put 24# and 30# brown corundum into the mixing pot according to the proportion and weight to mix evenly, then add phenolic resin solution, after the corundum abrasive is completely wetted, add cryolite and polytetrafluoroethylene powder in turn, mix well and then put in phenolic resin The powder continues to mix until the phenolic resin powder is evenly attached to each abrasive. Then weigh according to the single weight of the cutting piece and then feed the material. Before feeding, put the grinding wheel mesh, spread the material with a scraper, put a grinding wheel m...

[0056] Select the bonding mixed abrasive of the following ratio, and its ratio by weight percentage is:

[0057] 30# brown corundum abrasive 41%

[0058] 36# brown corundum abrasive 34%

[0059] Phenolic resin solution 5%

[0060] 240 mesh phenolic resin powder 10%

[0061] 120 mesh ice crystal 5%

[0062] PTFE powder (average particle size 5μm) 5%

[0063] Its preparation process is the same as that of Example 1, and the hardening curve is shown in Figure 1.

[0064] Using this formula and process to produce a 355*4.0*25.4 double mesh reinforced resin cutting sheet, it can cut 60 rails made of PD3 by 1 knife, with a loss of 55mm, and the entire cutting process is normal.

example 3

[0066] Select the bonding mixed abrasive of the following ratio, and its ratio by weight percentage is:

[0067] 30# brown corundum abrasive 41%

[0068] 36# brown corundum abrasive 36.5%

[0069] Phenolic resin solution 5%

[0070] 240 mesh phenolic resin powder 10%

[0071] 120 mesh cryolite 5%

[0072] PTFE powder (average particle size 5μm) 2.5%

[0073] Its preparation process is the same as the above examples, and the hardening curve is shown in Figure 1.

[0074] Using this formula and process to produce a double mesh reinforced resin cutting sheet with a model size of 355*4.0*25.4, after cutting a 60 steel rail made of PD3, the loss is 25mm, and the entire cutting process is normal.

[0075] According to the above three examples, the comparison of the use effects of the three cutting sheets produced by the above three examples is shown in the following table 1:

Abstract

The present invention is one kind of resin grinding wheel with teflon dry grinding lubricant and its making process, and belongs to the field of metal cutting and grinding utensil. The resin grinding wheel is made through preparing adhesive abrasive material mixture with brown corundum abrasive material 40-80 %, phenolic resin liquid 1-5 %, phenolic resin powder 3-15 %, teflon dry grinding lubricant 0.5-5 % and cryolite stuffing 2-10 %, and pressure forming. The resin grinding wheel with teflon dry grinding lubricant has high grinding and cutting efficiency, long service life, capacity of destructing obstruction and no chemical corrosion to the machined metal.

Description

technical field [0001] The invention relates to a resin grinding wheel containing polytetrafluoroethylene dry grinding lubricant and a manufacturing method thereof, belonging to the field of metal cutting and grinding tools, in particular to metal cutting and grinding grinding wheels. Background technique [0002] Resin grinding wheels are widely used in mechanical metallurgy, construction, military industry, railway construction and other fields. They are mainly used for cutting and grinding general metal materials such as steel pipes, steel bars, and steel bars. The so-called resin grinding wheel includes resin cutting grinding wheel and resin grinding wheel. Resin grinding wheel cutting disc is a cutting disc formed by mixing resin binder and corundum abrasive to form a cohesive abrasive, and then pressing and forming a cutting disc on the grinding wheel mesh. Compression molding, some grinding wheels are added with mesh, and some grinding wheels need to be inserted into...
