resin bonder grinder wheel for ceramic Resin bond diamond wheel grinding carbide coated ring

Resin bonder diamond wheel

Resin bonders are used to bond loose abrasives, solidify into a certain shape, and after heating and cementing, they have a certain degree of hardness, strength and grinding performance. The resin binders are composed of binders (resins) and various fillers.

The physical and mechanical properties of the binder are greatly influenced by the type and amount of filler.

Therefore, the type and amount of filler must be chosen reasonably.


Resin bond should have the following properties: good bonding performance, strength of the bond should be high, hardness should be appropriate;

Good heat resistance can improve the grinding efficiency and reduce the surface roughness of the workpiece.

Good economy and environmental protection.


The resin that makes resin abrasive tool commonly is man-made phenolic resin, epoxy resin, polysulfone resin, polyamide.

For the special requirement of quartz grinding tool, mainly phenolic resin, some other resin is added.

Such as phenolic - epoxy resin, phenolic - polyamide.

Grinding wheel usage


Grinding wheel operation

1. Before using, please check the resin grinding wheel whether it has cracks and mute. If yes, cannot be used.

2. The line speed of resin diamond wheel shall not exceed the provisions of safe working line speed.

3. Dressing the grinding wheel, we should use the special dressing tool.

4. In the grinding process, we should be chose the correct coolant.

The reason and solution for the waste of resin bond grinding wheel

There is no doubt that the emergence of waste is not a kind of loss for enterprises. There are two kinds of waste, one is repairable and the other is irreparable.

In reality, any enterprise is trying to improve product quality, so as to improve the market competitiveness of its products and make it invincible in the fierce market competition.

Here are some reasons and solutions for waste of resin grinding wheel:


1. Raw material size and hardness of resin grinding wheel are inconsistent

Method: strict according to ingredient list business accounting ingredient, check is key procedure;


2. Body crack of forming blank

The hot pressing temperature is too high, the commodity is too cold and hot, the temperature is too low when the core is removed, the core should be removed in time, the raw material is subjected to moisture transformation, or mixed material fault;

A. End crack

Molding material plasticity is poor, the method of unloading mold and taking billet is improper.

Forming mold base is uneven or the backing plate is not too parallel.

B. peripheral cracks

Die wear is severe, when unloading die, too skew.

C. Aperture crack

The strength of blank part is low, the vibration during mold unloading is too big, the core rod wear is too big or the taper is too small, and the order of mold unloading is not in accordance with the technical rules.

D. Diagonal cracks

The selected spring pad iron does not have the same spring force and causes diagonal grain in the die.

Speed limit of fine abrasives too fast, insist on short pressure time, too large space for mould cooperation.

E. Prevention of crack on resin grinding wheel

F. the plasticity of the mixture is well regulated, the molding tool shall not exceed the regular wear standard, the template and the pad iron shall adhere to excellent flatness, the thickness of the pad iron shall be used together, and the spring force of the spring pad iron shall be used together, and the mold shall be unloaded according to the order of technical rules;


3. The mixed

Mix before and mixing process next to the side, with the finishing equipment.

Check all raw materials for impurities before adding ingredients.


4. Uneven mixture

Mix according to technical requirement.

Replace the parts of the mixer which wear too much at any time.

The powder resin material shall be screened according to the number and times of the technical rules.


5. Forming hardness is inconsistent

The first part shall be checked as required, no less than 30% of each batch of blank parts shall be checked, the weight of the weight shall be checked frequently, and the survey pressure shall be changed.


The bridge is uneven.

Uniform cooling is required;

The appearance of the part "warping" without flat plane is called bridge leng.

This is caused by uneven cooling resulting in the shortening of the workpiece.

Come from thin section grinding wheel and fine grain thin product more.

It is very easy to produce the bridge end waste when the grinding wheel cools too fast.


7. Uneven arrangement and uneven hardness

Adjust the dry humidity of the mixture to make it have excellent molding.

According to the technical requirements for the operation of material and scraping.

Press the technical requirements first with the pad iron, adhere to the accuracy of the press;

Uneven striping, wet mix, or aggregate, uneven feeding, wear of the mold, severe leakage, need to replace the mold;


8. The two ends are not parallel

Stick to the precision of the pressure machine and operate according to the technical rules.


Uneven appearance.

The equipment is protected within the precision range required;


9. Blister

Control the temperature hardening according to the standard hardening curve of commodity, and control the quality of blending process strictly.

Molding temperature is too high or too low, demand adjustment temperature.

The curing temperature is too high and the curing furnace is out of control.

Mismatch of the linking agent;

Some of the superhard grinding tools have a convex surface deformation or the whole surface of the swelling, and resin luster, some show a turtle - like crack.


Causes:

A. The heating rate is too fast or the temperature is shaken greatly, which simply makes the fine particle size, high hardness and tight arrangement of parts bubble and expand.

Because this kind of commodity contains connection dose much or stoma is small, if the temperature control is not accurate to make the heating rate is too fast, can cause connection agent to react violently, volatiles quantity increases sharply, the air pressure inside billet body is big and make the product bubble and expand.

B. The mixture of type materials is not uniform, and the materials contain a combination of agents or solvents with relatively low boiling point (such as ethanol and acetone).

C. Due to the negligence of mixing and molding process, the contact dose of the parts increased, the single weight increased and the pressure increased.
