Posed by chemical substances are mainly quartz
Posed by chemical substances are mainly quartz (silica), calcite (calcium carbonate, dolomite (calcium and magnesium) (carbon dioxide), kaolin (Hello, 2SiO, 2HO) and so on.
From the above analysis we can see that to reduce tool wear, reduce downtime, improve economic efficiency, needs to be done: a reasonable selection of tools, the tool and engine power, milling pavement materials, milling depth and forward speed to match; adequate watering Segment temperature reduction, and efficient conveying systems to reduce the milling chamber reactor materials. Second, the worn tool tip led to a different cutting diameter, milling off the road is not flat, reducing the quality of the machine operation. Figure 5 is a carbide tip (tungsten cobalt) wear scanning electron micrographs. Described above is not found in the normal wear and tear and normal wear blunt Segment Segment Segment extreme right), on the need for timely replacement. Cutter crack easily after the wear and tear should be replaced immediately.
Can be seen from Table 1, the road material contains a very high hardness of quartz, the hardness near the carbide. Asphalt concrete pavement material is mixed materials, energy spectrum analysis know-main component elements are silicon, calcium, aluminum, carbon, potassium, iron and other elements, in which content is more silicon and calcium. Normal wear and tear process shown in Figure 7, such wear and tear conditions to maximize the extended tool life.
smcc-group. Therefore, the timely replacement of worn tool is beneficial to increase economic efficiency.
As the shank itself hardness lower than the tip, they are often the first to be abrasive. This occurs should immediately check the conveying belt speed, if there is no question I will replace the cutter BT-ER Spring Collet Chuck head, the use of larger diameter at the bottom tip of the cutter head, the effective protection of knife handle..com is a professional manufacturer of , we offer various of Cheap as your requirement. Asphalt concrete pavement is a high consistency of asphalt binder, heated at high temperature minerals in materials with a variety of forced mixing, paving, rolling made. A clear direction pits and scratches, and this is hard quartz particles on the alloy particles produced by wear and tear tip. First of all, with the tip wear, tip diameter and larger, resulting in reduced cutting ability, which also reduces the machine&SFM Square Face Mill Head39;s operating efficiency. This should be tungsten carbide alloy cutting tip assume their tasks, because of the shape of the tool, the installation location and poor working conditions, resulting in knife handle some direct contact with the pavement material, friction wear. But in the actual construction process, the cutter head often can not achieve the desired state of wear and tear, resulting in the following non-normal wear and tear, as shown in Figure 8. Note that replacement must use copper hammer typing, to prevent the alloy crack Cutter Knife Block Knife Block replacement need to mark lines to assess the wear and tear. Causes partial wear more complex and may include: watering enough, leading to overheating tool; knife block excessive wear and tear; milling high levels of sticky asphalt material, the use of light Segment; small milling waste into the knife handle and spring up between the and so on.
Partial sharpening head in the milling process does not rotate, only on one side produces wear and tear, will result in eccentric wear.
Replacement Tool
Tool replacement for two reasons. Tip hardness have enough surplus to connect tip of the knife handle part of the # excessive wear and tear, if not immediately replaced, wear insufficient to support the knife handle was broken cutting tip, and then began to wear a knife block, causing greater damage to the machine. Can be seen, sometimes layered milling but more economical. Eccentric wear of the cutter head is also needed to replace.
Tool Wear
Tools, in particular, Cutter, life is very low, in the process of breaking ground with the ground and waste generated intense friction, wear and tear quickly. In addition, the milling deep and large, forward speed is small, then the small size milling waste on the tool wear is also more serious, single-output also dropped the knife. A variety of materials structure and morphology and hardness shown in Table 1 . A 2 million milling machine milling depth and forward speed as shown in Figure 3. Although the delay in the replacement of tools to make it in the worn state to continue its work, you can save the cost Cutter, but the blunt of the cutter head will reduce the pace of work and reduce milling yield. Because the milling depth increased, and forward speed is bound to decrease. In order to Blade wear uniform, knife cut into the ground, Blade tip path plane of the axis is not, there is a certain angle, prompting Cutter cut into the ground at the same time, knife block hole rotation, uniform wear and tear. Figure 6 is to use 45 steel knife handle made of wear and tear after the scanning electron micrographs, near the tip Department has significant scratches and furrows. When they find the machine vibrations increase, milling after the roads are rugged, you need to stop checking Segment.
Crack tip suddenly encountered in the milling process of a hard object, such as steel, Manhole cover, large pieces of cement and so on, tip easy to crack.

Tools and practices
It seems simple, operational efficiency and the milling depth and speed of the advance. Large milling deep, full speed ahead seems to be most productive time, but in reality not the case. Through the above analysis we can see that a reasonable tool wear mainly occurred in the upper tip and the knife handle. Figure 4 represents the single-Segment of a particular model to production and milling of deep relationship. When the flag when the line was finished grinding, you need to replace the knife block.

The replacement of a specific time is felt by the manipulator by the vibration of the machine and observation to determine the road surface after the milling tool wear
