Sintered diamond cutting discs: two sub-cold sintering sintering and pressing, pressing and sintering. 3 to ensure the processor after the lower concrete clean, faithful, no effect bonding debris. 2 highway bridge expansion joints and concrete pavement repair craft system introduced. When assimilates from the kiln into the granular guilty police. In the heat (temperatures above 30 & 8451;), dry, windy weather premise, with wet sacks coverage four hours to repair the surface. Control the porosity is to optimize the grinding process, cutting sheet prices and, therefore, optimize production costs juncture. Fill the already cut steel parts rust tick chisel, restore the structure contours. Diamond cutting sheet manufacturing process is divided into two: 1, sintered diamond cutting discs: two points and hot-cold sintering sintering, pressing and sintering. 2, welding diamond cutting discs: two minutes of high-frequency welding and laser welding, high frequency welding temperature molten media through the head and the substrate are welded together by laser welding high-temperature laser beam will head contact with the substrate edge melts to form a metallurgical bond . 3. Diamond cutting discs: the head is attached to the inner matrix powder grinding grinding characteristics of the upper corner by plating methods: ① due to restrictions within the circle diameter, Xinjiang cutting, angle of internal grinding diameter grinding small, speed is limited within the grinder spindle speed (usually 10 000-20 000 r / min), the peripheral speed of angle grinding typically reach 30-35 m / s, and therefore the mass ratio of cylindrical grinding surface grinding cut difference. ② when grinding inside diameter smaller cut sheet sales, installation angle grinding pick a major axis diameter is also smaller, but longer overhang, poor rigidity, prone to bending deformation and vibration, affect the size and shape accuracy accuracy and reduce the surface quality, but also limits the amount of grinding is not conducive to mention Gao productivity. When within ③ grinding, angle grinding diameter is small, the speed is much higher than the cylindrical grinding, so the number of grains per unit time for each to participate in the grinding higher than cylindrical grinding, and cut into the workpiece within round-contact, the contact is longer than the outer arc grinding, cutting slices manufacturers, coupled with the internal grinding in a semi-closed state, cooling conditions are poor, grinding heat larger, abrasive easily blunt, easy to plug angle grinding, the workpiece easy to heat and burns affect the surface quality.
