Grinding wheel use precautions

1. Please check carefully before installing the cutting wheel to confirm whether the cutting wheel is deformed, cracked or collapsed.
2. When the flange is too small or the precision is poor, the fiber cutting disc Chinese supplier is easily damaged. Please use it after improvement.
3. When the cutting wheel is marked with the direction of rotation, it must be in the same direction as the machine. On the contrary, the cutting is not sharp and it is difficult to perform the performance of the cutting wheel.
4. If a cutting wheel that does not match the cut workpiece is used, it is prone to abnormal wear, poor sharpness, abnormal heat, and the like.
5. If an abnormality is found during the cutting process, stop immediately.
6. When the cutting is not sharp, the grinding wheel should be trimmed. If it continues to be used, it will cause overheating and overloading and damage the grinding wheel.
7. In the rotation of the grinding wheel, it is strictly forbidden to cut by hand, and it is not allowed to touch the grinding wheel by hand or body.
8. The cutting wheel is strictly prohibited for operations other than grooving or cutting, to avoid abnormalities due to uneven force.
9. The surface quality and cutting performance of the workpiece are mainly related to the abrasive grain size of the durable cutting off wheel. The finer the particle size, the better the surface finish. At the same time, it is also related to the workpiece material, hardness, cutting amount, machine tool conditions, processing requirements and other factors.
10. The ultra-thin cutting wheel has been shaped and edged before leaving the factory and can be used directly by the user. If the user needs further shaping, it is recommended to use green silicon carbide or white corundum whetstone. The particle size is larger than the size of the cutting wheel. If the user needs to further sharpen or use a section of the blade, it is recommended to use green silicon carbide or white corundum. Whetstone, the size of the cutting wheel is finer than the size of the cutting wheel 1-2 or the same number.

Slice deformation problem

The deformation problem of the resin grinding wheel is a difficult problem that has long plagued the fiber cutting disc Chinese supplier manufacturer. The root cause of the deformation is the uneven organization in the effective area of the grinding wheel, which in turn causes uneven stress in the hardening process of the product.
Resin grinding wheel manufacturers should focus on solving the uniformity of the mixture, the uniformity of the molding and the stability of the mesh. Only the above three problems can be solved step by step. The deformation problem of the resin grinding wheel (mainly the cutting wheel) Solve the solution.

Large sections (resin-cutting wheels with an outer diameter of more than 300 mm) have appeared in different regions and related manufacturers.

The large slice (resin cutting wheel with an outer diameter of more than 300 mm) is mainly characterized by the fact that when the grinding wheel is cooled and the appearance is detected, the hand is shaken in the diameter direction when shaking, and the bending is obviously soft; when the customer uses the grinding wheel to cut The performance is that the grinding wheel is yawed, the holding force of the flange is not enough, and the serious will be broken and broken.
Large-section film is also a technical problem that has long plagued resin abrasive manufacturers. The main reason for the analysis is the uneven stress of the grinding wheel during the hardening process.
Resin grinding wheel manufacturers should pay attention to the impact of environmental climate on durable cutting off wheel production, timely formulate countermeasures, rationally select suitable phenolic resin varieties, increase the uniformity of the mixture, and adjust the hardening process in a timely manner to make it more suitable for complete hardening of phenolic resin.
Paying attention to the above problems, the film problem will be avoided.

About grinding wheel characteristics and finishing solutions

In the daily cutting process, the loss value of the 12 inches cut off wheel is an important problem for the enterprise to overcome. How to maximize the use of the grinding wheel in the operation process is the basic operation method:
1) The finer the grain size of the grinding wheel, the smaller the roughness value

2) Abrasives should be selected that have affinity with the workpiece material

3) The hardness of the abrasive tool, when the workpiece material is soft and sticky, a harder abrasive tool should be used; when it is hard or brittle, a softer abrasive tool should be selected.

4) Using a grinding wheel with a larger diameter of the grinding wheel, increasing the width of the grinding wheel can reduce the surface roughness

5) Using a diamond pen with good wear resistance, suitable cutting edge shape and installation angle, when the dressing amount is appropriate (the longitudinal feed amount should be smaller), the abrasive cutting edge can obtain good contour and reduce the surface. Roughness.
Analysis of the characteristics of grinding wheel abrasive

The grinding work of the abrasive is carried out under the conditions of high speed rotation, high temperature, high pressure and grinding fluid. Therefore, the abrasive needs to have: high hardness, suitable toughness, self-sharpness and chemical stability.

Abrasive hardness: refers to the degree of resistance of the abrasive when it is pierced.

Toughness: The ability of an abrasive to withstand pressure without breaking or cracking.

Grinding wheel abrasive properties:
It must have a very hard mineral crystal structure to be able to crack without excessive pressure during grinding.

When subjected to an external force during processing, it can have good toughness, is not easily deformed, and is not easily worn.

It must have heat resistance, local high temperature generated during the grinding process, it is not easy to melt the particles, and there may be burned parts.

At the same time, the grinding wheel abrasives also need to have chemical stability, because the standard cut off wheel for metal grinds a wide variety of workpieces, steel, ceramics, gemstones, cloth, causing chemical instability, which is quite destructive to the workpiece.

Should pay attention to the use of cutting disc

The main causes of normal wear of the thin flat cutting disc are chemical wear, mechanical wear and heat. The former is caused by the scoring action of hard spots in the workpiece material, and the latter is caused by diffusion, adhesion, corrosion and the like.
1, abrasive wear
At various cutting speeds, the tool has abrasive wear. At low speeds, other forms of wear are significant, and abrasive wear becomes a major cause of tool wear. It is generally believed that abrasive wear is directly proportional to the cutting path. Abrasive wear Mechanical wear caused by impurities in the workpiece material, hard spots such as carbides, nitrides, and tellurides in the material carcass.
2, bonding wear
During the cutting process, the bonding of the tool and the workpiece material is highly prone to sticking due to the conditions of high temperature, high pressure and fresh surface. When the relative motion continues, the bond point is broken by a large shear or tensile stress, generally occurring on the side of the workpiece material having a lower hardness. However, the tool tree material often has defects such as uneven organization, internal stress, micro-cracks, voids, and local soft spots. Therefore, the surface of the tool is often broken and taken away by the workpiece material to form a bondage defect. Adhesive damage occurs in various tool materials. Bonding is the bonding phenomenon caused when the cutting disc is connected to the workpiece material, which is also called cold welding.
Angle cutting disc use
Angle cutting disc use diamond resin grinding wheel use:
1. The angle cutting disc can be selected according to the product model. For the purpose of the angle-cutting disc, the cutting disc for stainless steel can be rotated at high speed during operation, and the metal or non-metal workpiece can be ground, grooved and cut.
The range of angled cutting discs is very single. However, according to the abrasive used, it can be divided into ordinary abrasives and natural grinding wheels; according to the shape, it can be divided into flat shape, oblique side, cylindrical shape, cup shape, dish shape and the like.
According to the binding agent can be divided into equal.
Angular cutting disc is a kind of nylon product with a wide range of economical and applicable applications. The secondary application range is decorative grain treatment, cleaning, metal polishing, deburring, common use for strap decoration, watch case, metal equipment, Stainless steel doors and windows, kitchen utensils disposal; golf clubs, ball heads; stainless steel pipe fittings; door handles and other metal parts polishing.
