Scarifier Cutter Tool Structure and Failure Factors
The scarifier cutter tool consists of four parts: 1. carbide head, a. cutter body, 3. retaining ring, 4. elastic sleeve.
Carbide head of the cutter body by brazing, it directly involved in the milling of pavement; retaining ring knife body and a knife block separated so that no direct contact with the knife block, knife block to protect from being worn; Scarifier cutter Tool Installation in the knife block, your tool tight elastic sleeve with hard hole in the knife block, while the flexible pouches knife physical rotation tool in the milling process to ensure even wear and tear.
1. Not the particular milling surface hardness to select the match with the milling cutter, giving you abnormal wear for this tool.
2. Cooling water is not enough the first hot corrosion caused by carbide cutting specialist tools.
3. Milling speed and milling does not match the depth of wear and tear caused the knife block interference.
4. Knife within body and elastic sleeve has been catching sand, milling cutter body as soon as the flexible pouches just cannot rotate, resulting in partial cutting tool wear.
The rational use of three tools
Tool for the above four failure factors, proposed by the rational use of tools measures:
In order to prevent interfering in a knife block tool wear caused by excessive wear, recommend the following milling speed and milling depth of the corresponding table:
Milling depth from the larger, the tool in contact without the pain . material the longer the more friction and heat to be able to avoid carbide cutter head heat loss, the need strengthen the amount of cooling water spray Segment. When the milling, when the depth of shallow (5cm below) should reduce the amount of cooling water spray Segment in order to throw totally to reduce the milling tool and being under the prospect of contact materials lower tool wear.
Under the power of size in the milling machine, milling of hard and soft road conditions in the associated with cutting tools
Wirtgen listed under the outstanding tools and tool Knnametal associated with operating conditions in numerous construction
Every 6 to eight hours of work, inspection tool rotation and wear, ensure that the installation tool can be freely rotating knife block hole, the tool should be the timely replacement of significant wear and tear; tools extend the length of the impact close to the construction quality on the more large, the replacement tool supplementations to ensure the extended length within the line tool; if half of milling tool wear serious need of replacement, it is recommended to replace the entire tool is out; used, but wear and tear is not serious re-combined into several tools, continue for usage this way, can guarantee the quality of road construction, but also to extend the tool life, reduce construction costs.
Through the above analysis and figured with the construction process, the rational use of the scarifier cutter construction quality, construction efficiency and construction cost of great significance.
