1. If the shaft head rotates inflexibly or the noise is high during operation, the bearing may be damaged. Just replace the bearing. Since the shaft head is running at high speed for a long time, the bearing is easily damaged and the bearing must be replaced every 3-4 months.

2. If the shaft head does not rotate during operation, the motor may be damaged. Just replace the motor.

3. If the load is too heavy during work, the blade may not be crazy, just replace the blade.

4. Elimination of edge collapse:

(1) Both sides chipped when inserting bricks: a. The blade is not sharp, b. Insufficient water cooling, c. The track is not parallel to the four guides, d. The machine head bearing is damaged.

(2) The main reason why one side collapses when inserting bricks is that the blade and the track are not in a parallel line.

When the machine fails, it should be inspected and repaired as soon as possible. The bridge cutting machine should also be maintained and maintained normally.

We all use diamond saw blades more or less in industrial processing. Whether diamond can work efficiently is related to the concentration of diamond. The higher the concentration of diamond, the less efficient it is. In order to allow everyone to better use diamond saw blades, we briefly introduce the relationship between the working efficiency of diamond saw blades and diamond concentration.

Within a certain range, when the diamond concentration changes from low to high, the sharpness and sawing efficiency of the saw blade gradually decreases, and the service life gradually extends; but if the concentration is too high, the saw blade will become dull. By using low concentrations and coarse particle sizes, efficiency will increase.

When sawing, each part of the cutter head has different functions and uses different concentrations (that is, the middle layer in a structure with more than three layers can use a lower concentration). During the sawing process, a middle groove is formed on the cutter head, which helps prevent the saw blade from deflecting, thus improving the quality of stone processing.

We must keep in mind the relationship between the working efficiency of diamond saw blades and diamond concentration, so as to ensure that we use diamond saw blades better.

stone cutting blade


Which stone cutting blade to use for stone processing is a question that many stone accessories stores will consider. They will mainly choose based on sharpness and wear resistance!

First, it is necessary to ensure the rigidity and movement accuracy of the machine equipment. Only good rigidity and high-precision movement can suppress vibration at work, ensure smooth cutting, and make the stone cutting sheet processing more stable.

When cutting stone cutting blades, if the cutting speed remains unchanged, the sawing efficiency depends on the linear speed. Most stones have a good linear speed, and the wear of the saw blade is low at this speed.

Stone processing requires mining machinery in the early stage. The large stones mined are called blocks. Next, the blocks need to be processed. Block processing generally involves sawing and processing into stone slabs with stone cutting blades. For marble, it is also necessary. Small saw blades can be used for fine processing.

The processing of stone mainly involves a series of processes such as sawing, grinding, and polishing. The feasibility of stone processing by stone cutting blades is the ease of sawing, grinding, and polishing. These processes are very similar and are generally referred to as the feasibility of stone processing. Sawability and grindability.

The installation accuracy of the stone cutting blade and the spindle and the size of the saw blade chuck also have a great impact on sawing. Generally speaking, if the installation accuracy error is large, it will affect the sawing effect.

The cutting blades used on the cutting machine are only two types: metal (or hard alloy) and diamond grinding wheels, but their sizes are determined according to the cutting machine. Therefore, you can find stone cutting machines and their cutting blades from professional stone cutting tool suppliers As long as you provide the cutting machine model, the supplier will list all the metal saw blades or grinding wheels for you to choose from and exchange them freely



1. First, align the wrench with the hole on the fixed block of the cutting machine and loosen it counterclockwise



2. It should be noted that there is a small button at the back of the cutting machine, which needs to be held down before the cutting blade can be twisted out, otherwise it cannot be twisted out



3. After loosening, remove the fixed block and old cutting blade of the cutting machine



4. Then install the new cutting blade and tighten the fixed block, don't forget that the button at the back still needs to be pressed



5. Finally, the replacement of the grinding wheel for the handheld stone cutting machine is completed

Stone cutting is a necessary process during the processing of stone slabs. Only the cut stone slabs can become building materials that facilitate subsequent processing, and the stone cutting machine is a mechanical equipment for cutting stone.

The stone cut by the stone cutting machine is flat and in the right shape, and can be put into the subsequent grinding and polishing process well. The stone cutting machine has high cutting efficiency and high precision, and is very suitable for cutting large quantities of stone.

In order for the stone cutting machine to be used well and for a long time, we must pay attention to the maintenance of the stone cutting machine in daily operations. So, here are several aspects of maintaining stone cutting machines in daily life:

1. After the stone is clamped, it is strictly forbidden to move the blade when the host is not started to prevent the blade from hitting the stone and damaging the blade.

2. The test block must be clamped firmly to prevent loosening.

3. After clamping the test piece, use a dry towel to dry the water stains on your hands before operating the button.

4. When disassembling the blade, place the E-type card in the two small holes of the back spindle pulley, and use a special wrench to open the spindle blade locking nut clockwise (note: the E-type card must be removed after the operation is completed)

5. If the main belt of the stone cutting machine is found to be loose, tighten the belt in time.

Wear problem

Any grinding wheel has certain usage wear requirements. When the wear reaches a certain level, a new grinding wheel must be replaced. In order to save materials, you cannot use it beyond the wear and tear requirements. This is an extremely unsafe and illegal behavior. As a general rule, when the grinding wheel is worn to a diameter that is 10 mm larger than the diameter of the chuck, the grinding wheel should be replaced with a new one.

Validity issue

The new grinding wheel taken out from the warehouse is not necessarily a qualified grinding wheel, and even the new grinding wheel purchased from the manufacturer is not necessarily a qualified grinding wheel. Any grinding wheel has a certain validity period. If it is used within the validity period, it is a qualified grinding wheel; if it is used beyond the validity period, it is not necessarily a qualified grinding wheel. The regulations stipulate that "grinding wheels should be used within their validity period. Resin and rubber bonded grinding wheels must undergo an inversion test after one year of storage. Only those who pass the test can be used."

Texture problem

During use, if cracks are found in the grinding wheel, use should be stopped immediately and replaced with a new grinding wheel to avoid accidents involving broken grinding wheels and injuries.

Diamond saw blades are a processing tool we use in industrial activities. Diamond saw blades are very sharp and wear-resistant, and have a long service life, so they are widely used. When we use the saw blade, we all hope to improve its work efficiency, and then we will tell you how to improve the work efficiency of the diamond saw blade.

The working efficiency of the diamond saw blade is related to the diamond enclosing strength, the diamond particle size and concentration selected for the cutter head. The higher the diamond concentration selected for the saw blade, the greater the average density of diamond on the working surface of the diamond saw blade, the higher the wear resistance of the diamond saw blade, and the longer the service life.

The greater the longitudinal density of diamond in the working layer of the saw blade, the more diamond layers in the working layer of the diamond saw blade, the more diamond layers in the carcass, and the longer the service life of the diamond saw blade. The longitudinal density of diamond in the working layer on the surface of the saw blade is related to the diamond particle size and concentration selected for the saw blade.

The higher the diamond concentration, the greater the longitudinal density of diamond in the working layer of the diamond saw blade, and the more diamond layers in the diamond saw blade; the finer the diamond particle size selected for the diamond saw blade, the greater the diamond layer in the diamond saw blade. The more the number, the higher the wear resistance of the diamond saw blade.

Diamond saw blades are just like our common kitchen knives. They will inevitably become dull after a long time. Another reason is that the sharpness of the diamond saw blade itself is not good. If the diamond saw blade is not sharp, it can be properly polished, but it cannot be polished at will. It is necessary to use special grinding tools or contact the manufacturer directly for consultation.

It is inevitable that the diamond saw blade will become blunt after a long time of use, but if you choose a saw blade with good sharpness, you can delay the blunt time.

Everyone knows that diamond grinding wheels are used to grind many hard, high-hard and brittle materials with special effects. The methods of metal bond diamond grinding wheels are mainly sintering and electroplating. How do we maintain them during operation?

1. When the diamond grinding wheel stops running, it needs to be laid flat or hung up by using the inner hole. Do not place objects on the saw blade that is placed flat. When the operating environment is dark, pay attention to moisture and corrosion.

2. Coolant should be used as much as possible during grinding, which can not only improve the grinding efficiency and quality, but also reduce the wear of the grinding wheel. Commonly used coolants include kerosene, light diesel oil and light gasoline, etc., and kerosene is generally preferred.

3. When it is found that the diamond grinding wheel is no longer sharp due to long-term operation and the cutting surface is rough, it needs to be ground and leveled. But it should be noted that grinding cannot change the original angle of the diamond grinding wheel, otherwise it will destroy the dynamic balance.

4. When using a grinder, some operators, especially young operators, use too much force in order to grind quickly, which is a very unsafe operation behavior. Any grinding wheel itself has a certain strength, which may cause the grinding wheel to break and even fly out of the injured person, which should also be prohibited.

5. When there is a problem with the inner diameter of the diamond grinding wheel, the processing of the positioning hole, etc., it needs to be repaired by the factory. Otherwise, poor processing due to unprofessionalism will affect the effect of the diamond grinding wheel, and may bring safety hazards to the operator. Normally, the reaming should not exceed the original diameter of 20mm, so as not to affect the balance of stress.

6. If the diamond grinding wheel is not used immediately, it should be placed flat or hung up by using the inner hole. Do not stack other objects or step on the flat saw blade, and pay attention to moisture and corrosion.

marble cutting blade

Very common in marble processing. When it comes to cutting marble, it needs no introduction. It is a professional cutting piece for all kinds of marble stone. Now we can see it in many places, such as in architectural decoration.

Mainly used for stone cutting. Here we mainly understand the correct and effective cutting. What should I pay attention to?

First, prepare the marble cutting pieces for cutting. According to the angle grinder used by the saw blade, the angle grinder is generally hand-held. The most common is the cutting machine that can be bought in the hardware store. After choosing the machine, first measure the size, cut it into the size you need now, and then install and fix the stone slab.

It is best to add water when cutting. The purpose of adding water is twofold. One is to reduce the flying of dust, and the other is to reduce the temperature of the marble cutting blade during cutting. This can increase the service life of the saw blade, and the saw blade will not be deformed due to excessive temperature, thereby improving the cutting accuracy.

Use a portable disc cutter to install the marble cutting blade and cut from the back of the tile. The square hole is intact from the surface of the tile, but the back is scratched. When opening a round hole, use a portable disc cutter to install a marble cutting piece to cut from the back of the tile, and cut a cross in the middle. Knock a round hole from the surface.

Install the marble cutting disc on the cutting machine, adjust the cutting depth, place the artificial marble on the workbench, determine the size and start cutting.

Now lay the artificial marble flat, measure the size with a ruler and draw a line, then install the stone cutting blade and cut slowly from the line. If necessary, water can be added to the mineral water bottle for greater efficiency.

Let me tell you about the two processes of diamond segments: cold pressing and hot pressing.

When processing the diamond segment with grooves on both sides in the traditional method, it is divided into two steps. First, the diamond segment is cold-pressed, and then the diamond segment is hot-pressed.

Cold forming of diamond segments:

It is the shape required by the direct forming section on the cold pressing mold. The cold pressing mold includes five parts, the upper pressure head, the lower pressure head, the center plate, the front end plate, and the rear end plate. The arrangement sequence of each part is used to form the required shape of the section. The cavity, fix the periphery of the cold press mold, so that the cavity will not be deformed after pressurization, then add the required powder in the cavity, put it into the upper pressure head, and pressurize, so that the powder changes from loose to Stop pressurization when the required segment shape is in solid shape, separate the fixing devices around the cold pressing mold, and separate the cold pressing mold, take out the segments one by one, arrange the regular segments manually, and wait for use.

Diamond Segment Hot Press Forming Process:

That is, put the cold-pressed diamond segment on the hot-pressing mold, and warm-press forming. The hot-pressing mold includes five parts, the upper pressure head, the lower pressure head, the middle plate, the end plate, and the side plate. Cavity, put the cold-pressed diamond segment in the cavity, fix the periphery of the hot-pressed mold and put it into the sintering equipment, so that the diamond segment is melted under warm pressure to form an alloy, and finally shaped, finally cooled and decompressed, dismantled Fasten the device and take out the diamond segment.

In the segment manufacturing process, the selection of the segment carcass material and the hot pressing process are the more important links. Co-based and bronze-based alloys are generally selected as the carcass material, but they cannot be achieved in terms of manufacturing cost and application performance. Good combination. Fe-Ni-Cu-W alloy was proposed as the segment carcass material through horizontal analysis. After testing and application, a relatively ideal combination of manufacturing cost and performance was obtained.

The manufacturing process of the diamond segment can be described as a sintering process of metal powder under a certain pressure, which is a powder metallurgy process: uniform and heterogeneous metal powder is sintered at a temperature (800-1000°C) and a certain pressure (180-250Kgf/cm2) ), through a series of physical and chemical effects such as dispersion, welding, compounding, and recrystallization among powder particles, a sintered body with a certain shape and mechanical properties is formed, which is a segment.
