Abstract
The present invention relates to a high efficiency grinding wheel and a processing method of the grinding wheel. After the heating processing, an ordinary grinding wheel is immersed into filling agents of gasoline or higher fatty acid or a mixture composed of the gasoline, the higher fatty acid and paraffin wax according to a certain proportion; after completely immersed, the grinding wheel is taken out of the filling agents and is volatilized until dried. The grinding wheel after processed by the method has the advantages of great improvement on grinding capacity, high smoothness, high quality of processed workpieces, short processing time and low environmental pollution. The grinding wheel can replace import cubic boron nitride grinding wheels, can replace diamond grinding wheels, greatly lowers the cost, and saves a large amount of foreign exchange for China.
Description
The present invention relates to instrument that grinding, polishing or sharpening use and the method for processing this instrument.Particularly increased the method for emery wheel and this emery wheel of processing of mixed filler.
At present, the steel of the mould of manufacturing cutter mainly contain: old high-speed steel, new high-speed steel, aluminium high-speed steel, vanadium aluminum steel and vanadium
3Nitrogen steel (its hardness increases in turn) also has carbide alloy firm in addition.Steel jaundice, annealing phenomenon appear in homemade emery wheel easily when the old high-speed steel of processing grinding, new high-speed steel and aluminium high-speed steel, and emery wheel consumption is very fast.The import cubic boron nitride abrasive wheel can grinding vanadium aluminum steel, but the grinding vanadium
3Nitrogen steel still effect are bad, and the emery wheel price is very expensive.
A kind of " through the emery wheel and the dirt facture that disappears thereof of the dirt processing that disappears " disclosed in Chinese patent 89101982.0, be that plain wheel is soaked into the back drip-dry in oil or fat or mixing deep fat that the two is made into by a certain percentage stand-by, its main purpose is to eliminate dust, reduce environmental pollution.Though processed workpiece surface quality increases, fundamentally the grinding effectiveness of emery wheel and the phenomenon that workpiece turns to be yellow, anneals are given full play in solution yet.
The method that the objective of the invention is to overcome above-mentioned weak point of the prior art and a kind of emery wheel of high effect is provided and processes this emery wheel.Steel turn to be yellow in grinding, the annealing problem thereby solve, the utilization rate of raising fineness, the grinding capacity of giving full play to emery wheel, raising emery wheel.
Task of the present invention is achieved in that a kind of high effect emery wheel, it is the emery wheel that adds bond pottery, resin and form by corundum class abrasive material (alundum (Al) or silicon carbide abrasive in the prior art with pore, handle through special: promptly whole emery wheel by gasoline, higher fatty acids or gasoline, higher fatty acids and paraffin by a certain percentage (weight %) filler of mixing soaked, make emery wheel contain this filler.
The processing method of this high effect emery wheel is as follows: 1. heat treatment, earlier emery wheel is heated, temperature is controlled in 20～80 ℃ of scopes, 2. mixed filler, it is even that gasoline, higher fatty acids or gasoline, higher fatty acids and paraffin are heated between 30～70 ℃ mixed melting in following ratio (weight %):
Gasoline 60～90% gasoline 30～90%
Higher fatty acids 10～40% or higher fatty acids 3～35%
Paraffin 3～35%
3. soak, volatilize, the good emery wheel of heat treatment is immersed in the hot mixed filler, treat to take out to volatilize after emery wheel soaks into fully promptly to obtain high effect emery wheel.
The present invention compares with prior art (emery wheel that does not add filler) has following advantage:
1. filled up domestic no special grinding wheel grinding vanadium
3The blank of nitrogen steel;
But 2. the cubic boron nitride abrasive wheel of import substitution, emery wheel price of the present invention only is 10～20% of a cubic boron nitride abrasive wheel price;
3. greatly improved the grinding capacity and the effect of emery wheel, tabulation expression (condition: use same grinding machine, processing is with a kind of aluminium high-speed steel workpiece):

4. emery wheel improves a grade use, reduces expenses 50%.General corundum wheel has three kinds, brown corundum, white fused alumina, pink fused alumina at present.Its price palm fibre corundum is minimum, and the more brown corundum of white fused alumina is high about 1 times, and pink fused alumina is high 1.3 times than white fused alumina.After adding mixed filler, brown corundum can replace white fused alumina to use, and white fused alumina can replace pink fused alumina to use.In addition, silicon carbide grinding wheel can replace skive after handling by method of the present invention.
5. because emery wheel is heated in grinding, makes mixed filler melt the absorption dust gradually, thereby reduced environmental pollution.
The present invention is described in further detail below with reference to embodiment:
Embodiment 1. is heated to 20 ℃ with corundum wheel.Mixed filler is pressed 9 kilograms in gasoline, 1 kilogram of palmitic acid, and it is even to be heated to 30 ℃ of mixed meltings, and the good emery wheel of heat treatment is immersed in the hot mixed filler, treats that emery wheel soaks into the back fully and takes out to volatilize and promptly obtain high effect emery wheel.
Embodiment 2. is heated to 40 ℃ with corundum wheel.Mixed filler is pressed 6 kilograms in gasoline, 4 kilograms of stearic acid, and it is even to be heated to 70 ℃ of mixed meltings, and following process operation is with embodiment 1.
Embodiment 3. is heated to 60 ℃ with silicon carbide grinding wheel.Mixed filler is pressed 3 kilograms in gasoline, 3.5 kilograms of stearic acid, 3.5 kilograms in paraffin, and it is even to be heated to 50 ℃ of mixed meltings, and following process operation is with embodiment 1.
Embodiment 4. is heated to 80 ℃ with silicon carbide grinding wheel.Mixed filler is pressed 9 kilograms in gasoline, 0.5 kilogram of palmitic acid, 0.5 kilogram in paraffin, and it is even to be heated to 40 ℃ of mixed meltings, and following process operation is with embodiment 1.
Embodiment 5. is heated to 70 ℃ with resin wheel.Mixed filler is pressed 6 kilograms in gasoline, 2 kilograms of palmitic acid, 2 kilograms in paraffin, and it is even to be heated to 60 ℃ of mixed meltings, and following process operation is with embodiment 1.
