LEMAN concrete cutting wheels Development Status

To solve these problems, scientists and technicians have been studied from various aspects, including the performance of low-temperature ceramic vitrified diamond grinding cement mass memory and the key factors affecting the development. Therefore, the study of high-strength, low-temperature, low thermal expansion depressed center cutting wheel coefficient and excellent performance of low-temperature ceramic adhesive is home to pottery wheel materials research. 
Tanaka T, EsakiS, Nishida K, etc. by selectively increasing the number of holes in the wheel and size, you can make self-sharpening wheel materials set times can be further improved. Jackson MJ, Barlow N, Mills B super hard materials by controlling the pore structure inside the pottery wheel, so that the production of grinding wheels with high bond strength, good grinding efficiency and cooling performance when grinding. 
Vitrified started on Toughening studies, such as binding agents for glass ceramics processing phase, adding an appropriate amount of suitable binders whiskers. They found that the addition of boric acid binding agent in silicon whiskers, one can suppress the generation of prevent at 100 ° C ~ 200 ° C when leaving the wheel due to the rapid expansion of the volume of cracks; hand whisker whisker itself can serve to enhance the effect to improve the tensile strength of the binding agent. 
Because when vitrified diamond abrasive combination of factors such as difficulty coefficient is relatively large, vitrified bond diamond wheels development and production has been hampered. I overcome the technical challenges of vitrified diamond, first in the domestic production of vitrified diamond grinding wheel with gems, and develop a variety of wheel size, has been favored gem processing field. In recent years, research and development of grinding PCD / PCBN cutting tools vitrified diamond grinding wheel, grinding PDC vitrified diamond grinding wheel series cutting disc for inox vitrified diamond grinding wheel in the market has a good reputation.

Grinding wheel is the most important one class abrasive

Grinding wheel is the most important one class abrasive. Abrasive wheel is a binding agent was added to the porous body by the pressure of the blank, made cut off wheels of dried and calcined. Abrasive wheel is one of the most widely largest amount, use face, high-speed rotation, can cylindrical, inner circle, plane and a variety of surfaces such as metal or nonmetal type workpieces when using coarse grinding, fine grinding and half grinding and grooving and cutting and so on. The wheel is a binding agent to form a certain shape ordinary abrasive solids (mostly circular, the central through-hole), and has a certain strength abrasive. Which generally consists of abrasives, binders and pores form, these three parts is often called abrasive three elements. Grinding wheel is the most important one class abrasive. Abrasive wheel is a binding agent was added to the porous body by the pressure of the blank, made of dried and calcined. Since abrasives, binding agents and different manufacturing processes, a large difference in the characteristics of the wheel, so the quality of the grinding process, productivity and economy has an important effect. The main characteristics of the grinding wheels is determined by the abrasive particle size, binder, hardness, structure, shape and size and other factors. Central wheels in combination with the abrasive agent and abrasive made ??of a circular through-hole.‍

Binding agent plays the role of holding the abrasive and concrete cutting blades‍ grinding a given geometry. It is an important sign of abrasive performance. Binders made ​​from thermoplastic resin binder composition with a variety of fillers, (the widely used phenolic resin, polyimide resin, a small amount of application; apply some filler metal oxides), the nature of its various components usage how many have a great influence on the physical properties, mechanical properties and grinding performance binders, therefore, must be selected for the workpiece material properties, flat cutting disc‍ in order to achieve good results.

concrete cutting discs on the scale of the knife

Use and maintenance knife when in use, first crop of about location, Cut off wheel‍ move left and right to adjust the crop size on the scale of the knife, then forced down the handle of the knife for cutting through the uniform. Generally can crop 4 to 5 80g paper. After the knife used for some time, you need to clean the cutting blades edge, remove the remnants of paper confetti. If the crop such as paper stickers and the like, but also at the cutting edge of the blade several times to clean, avoid adhesions confetti material impact on the effect of cutting again. 

The side cutter shaft can metal cutting wheels‍ adjust the tightness, easy cutting items when using different materials.

Diamond cutting discs mainly consists of two parts

concrete cutting blades belonging wheel, abrasive and binder resin made ??for ordinary steel, stainless steel sheet metal and nonmetal materials. concrete cutting concrete cutting blades made of glass fiber reinforced resin bonding material, with high tensile, impact and flexural strength, widely used in ordinary steel, stainless steel and non-metallic materials production, the excellent material, exquisite craftsmanship guarantee for high Cut off wheels cutting blades efficiency of different material of the workpiece and the best economic results. Resin cutting discs are resin binder, combined with a variety of materials, for alloy steel, stainless steel and other difficult to cut materials, cutting performance is particularly significant. Cut pieces of material and hardness of choice, can greatly increase your concrete cutting blades efficiency, saving you the cost of production. Diamond cutting disc is a cutting wheels tool that is widely used in the processing of stone, concrete, precast panels, new and old road, ceramics and other brittle materials, diamond cutting discs mainly consists of two parts;. Substrate and the substrate is bonded knife blade the main part of the head support.‍
