 1. Before installing the grinding disc, the marking of the cutting piece with high quality grinding disc factory price must be checked first. The grinding disc with unclear or no marking must be re-tested by the rotation, otherwise it is easy to be confused.
2. We must understand the working line speed of the grinding disc. If the cutting piece with a working line speed of 50m/s is installed on a machine with a working line speed of 80m/s, it will easily break.
3. Before installation, use a wooden hammer to tap the grinding disc. If a crisp sound is heard, the grinding disc is qualified. Otherwise, there may be cracks in the grinding disc. This grinding disc cannot be used.
4. The flanges sandwiched on both sides shall have the same shape and shape. The diameter of the flange is generally half the diameter of the resin grinding disc, and the inner side shall have a concave groove. Between the end face of the grinding disc with high quality grinding disc factory price and the flange, a thickness shall be placed. Approximately 1 to 2 mm of elastic cardboard or leather, oil-resistant rubber gasket, the diameter of the gasket should be slightly larger than the outer diameter of the flange.
5. The flange screws should be tightened symmetrically in order to make the clamping force evenly distributed, but the force should not be too strong, otherwise one side will be fractured.
6. After the grinding disc with high quality grinding disc factory price is installed, it must be idling for one minute. This is for the last time to check the quality of the grinding disc. After the installation, the cutting piece must be carefully checked before use. It should work under high-speed rotation conditions. The installation must be secure and balanced. To avoid personal and quality accidents caused by cracks in some quality problems due to high speed operation.

The above is the relevant matters needing attention in the installation of the grinding disc, then our Henan Aurora Abrasive Tool Co., Ltd. specializes in grinding disc cutting, grinding disc ultra-thin, Henan abrasive grinding equipment special equipment development and production management business.

High Quality Grinding Disc Production Process - Firing Process

2018-11-15 11:33:16 | 日記
The main working contents of the grinding process of the high quality grinding disc are: shaping before burning, placing the workpiece and vacuum firing.

The firing process of the high quality grinding disc is the most meticulous work of the brazing operator. To do this work, it is necessary to understand how the vacuum is built and how the temperature in the furnace thermal field changes. The principle of doing this work is: no solder can be placed in the non-welded place, the workpiece should be placed in the furnace, and strictly in accordance with the vacuum firing process.

Among them, the pre-burning shaping of the high quality grinding disc and the work of placing the workpiece are manually performed by one person. It takes 4 hours to complete the 500 grinding discs and share 4 working hours.

The vacuum firing of the high quality grinding disc is performed by a ZKR-3FH manual vacuum brazing furnace, which is usually performed manually by one person. It takes 12 hours to complete 500 grinding discs and share 12 working hours.

Classification of bonding agents for centerless grinding discs

2018-11-14 15:11:31 | 日記
There are three types of bonding agents commonly used in the high quality metal grinding discs:

1. Ceramic bond (code A). Ceramic binders are formulated from clay, feldspar and other natural silicates. These binders are abundant in the source, inexpensive, and have a wide range of applications. It can manufacture a variety of high-quality metal grinding discs with different particle size, hardness, structure, shape and size. It has stable performance, is not affected by climate and temperature, and is resistant to water, oil, acid and corrosion. It is suitable for grinding under various coolants. Dry grinding. The disadvantage is that it is brittle and does not tolerate severe vibration.

2. Resin binder (code S). The characteristics of this kind of bonding agent are high strength, high-speed grinding disc with a grinding line speed higher than 50 m/s and a very thin grinding disc; secondly, the combination with the abrasive grain is poor, and the high quality metal grinding disc made by the grinding disc is used. The grain is easy to fall off, and the grinding disc has good self-sharpness, so the grinding efficiency is low. However, the grinding disc wears quickly and is not easy to maintain the contour; the third is that there is a certain elasticity, and the contact surface between the high quality metal grinding disc and the workpiece is large, which not only increases the abrasive particles which are involved in cutting but also offsets part of the vibration, and is easy to obtain high smoothness. The disadvantage is that the corrosion resistance is poor, so the grinding disc made with it should not work under the reducing coolant, and the storage period should not be too long (limited to - year).

3. Rubber bond code X). It has a higher elasticity and a higher strength than the resin binder, and can be used to make a very large grinding disc. Since the rubber has good elasticity, the polishing effect is good during the grinding process, and high gloss is easily obtained. The disadvantage is that the high quality metal grinding disc is easy to wear, the shape of the grinding disc is poor, and because of the high density of the grinding disc, there is almost no air hole, and it is impossible to grind a lot of machining allowance, which is not suitable for rough grinding. At the same time, rubber has poor oil resistance and cannot be used as a coolant.

On the centerless grinding machine, the guide disc is mostly made of rubber bonding agent, and the grinding disc is mostly made of ceramic bonding agent. Sometimes, in order to improve the quality of grinding, the high quality metal grinding disc also uses a resin bond and a rubber bond.

At present, domestic high-speed grinding discs, although there are three kinds of bonding agents. However, at the time of manufacture, various additives are generally added to the binder. For example, alloying elements such as boron, lithium, barium and calcium are added to the ceramic bond grinding disc to improve the tensile strength of the bonding agent and ensure that the high quality metal grinding disc does not break at high speed.
