Influence the shape of cutting wheel, balance cutting performance

Influence the shape of cutting wheels, balance cutting performance:
(1), large thickness, cut slit width, wheel consumption; when the strength of the guarantee, the thickness as small as possible, saving wheel material is cut and save material; flat shape of large, slit width is determined by the thickest , but the intensity is determined by the thinnest, stone cutting wheel wear large and vibration, it will affect the entire cutting process. Wheel can be made thin in the middle, surrounded by thick is physical status.
(2), when the wheel runout is large, at the beginning of the cutting vibration, could easily lead to wheel off the block, on the strength and cutting, but cutting automatically after finishing a smaller overall impact.
(3) When the wheel side to beat the big time, cutting back and forth, cutting width large. Cut unnecessary material consumption, grinding wheels consumption naturally big, big impact.
(4), when the imbalance in the cutting vibration, could easily lead to wheel off the block, the impact strength.

Tile cutting wheelswidely used in a lot of cutting and metalworking sectors

Tile cutting wheels widely used in a lot of cutting and metalworking sectors slotting process to achieve the thinnest 0.1 mm, it completed the general saw cutting blades can not complete the processing tasks, especially high-speed enhancement after cutting discs are widely used, cutting Wheel requirements increase rapidly. In the grinding process, the surface roughness is conducive to meet higher demand. In the machining process, the grinding and polishing processes more use resin bonded grinding wheels, grinding under the same conditions, the resin abrasive finish higher than ceramic abrasive.

Cutting wheels molding include

Cutting wheels molding include: hot, cold, rolled three methods. Thermoforming law required little pressure. Molding density, high hardness, good strength; Northern China multi-pressing method; the advantages of cold pressing method is not required when the heat source for various combinations of abrasive agent; multi-use cold southern China, France; rolling law to be energy small, green density, low efficiency, are less common. Generally without reinforcing sheet wheel and export network in Bo resin sheet grinding wheel.
Cut off wheel hardening temperature is too low, too high, the holding time is too short, too long and are on the cutting performance disadvantage.

Best results of cutting wheels cutting conditions

Best results of cutting wheels cutting conditions:
1. The grinding wheel cutting line speed must be greater than 80 m / sec;
2. The grinding cutting tools must be water cooled cooling water flow is not less than 2.4 l / min;
3. The grinding wheels cutting depth is determined according to the thickness and cutting material. Usually within a maximum cutting depth of 3 mm;
The selection of films wheel, in order to ensure optimum cutting results, depending on the cutting material should select the appropriate grit size of the grinding wheel.

Improving the performance of the grinding wheel

Improve the performance of the abrasive surface and interface between the resin and bonding to improve bonding capacity, improve the mechanism of the mixing process and the performance of the grinding wheel. By heating, vacuum means of abrasive treatment to obtain a clean surface; for abrasive cutting wheels test results prepared by orthogonal experiment data processing and variance analysis, the results showed that: vacuum and heating can improve grinding wheel performance, vacuum pumping effect in improving the performance of the grinding wheel is more pronounced. By evacuation and heating can improve the surface between the abrasive and adhesive resins - Interface performance, enhance its bonding capacity, improve performance grinding wheel.
