Finishing of superabrasive ultra-thin sheets:
Trimming usually involves shaping and sharpening. Shaping is to achieve the required geometry and precision of the ultra-thin sheets while achieving the balance requirements. Sharpening means that the ultra-thin sheet is passivated or not sharp. During the trimming, the bonding agent between the abrasive grains is removed, so that the abrasive grains are exposed to a certain degree to form a cutting force, and a certain gap is formed between the abrasive grains to accommodate the cutting shoulder.
Ordinary ultra-thin shaping and sharpening can be completed in one dressing, while for super-hard abrasive grinding wheels, it is often necessary to divide the first and second processes. Because the super-hard abrasive ultra-thin is trimmed with single-grain diamond, the shape and dimensional accuracy of the ultra-thin sheet are affected due to the excessive wear of the dressing tool. If trimmed with a diamond roller, the dressing tool can be prevented from wearing too fast. However, the shape after trimming is very smooth, the grinding performance is poor, and it needs to be sharpened after shaping.
Diamond cutting sheet features

The large plates for domestic production of laminate flooring are mostly 1.22mx2.44m, which are cut into small plates of a certain length and width through a multi-saw saw production line. In order to improve the utilization efficiency of the equipment, improve the quality of the sawing and reduce the cost of the tool, diamond circular saw blades are often used. The specifications and angle parameters of the diamond standard cut off wheel for metal are: 250mm x3.2/2.2 x100mm, the number of teeth is Z36, the tooth shape is flat tooth (FZ), the front angle is 3°, the back angle is 10°, and the front tooth surface has a concave angle of 0.4. °, the back teeth with a concave angle of 6°. Diamond cutting discs are generally not clamped in a flange, but are clamped with an arbitrarily positioned hydraulic clamping shaft set. The interior of the hydraulic clamping sleeve has a cavity filled with hydraulic oil. When the pressure is applied, the inner wall of the hydraulic shaft expands and evenly encloses the saw shaft, completely eliminating the matching clearance between the inner hole of the foot saw blade and the saw shaft, ensuring that the twisting center of the cutting piece and the axis of rotation of the saw shaft are uniform, and the rotation is reduced. The radial runout of the teeth ensures that all the teeth are balanced to participate in the cutting.
Features:
1) Reduce the weight of the saw shaft component S and the unbalance of the saw shaft, and extend the service life of the bearing
2) Reduce the damage of the material below the cutting plane and the motion ripple, reduce the chipping phenomenon, and improve the processing quality of the workpiece surface.
3) No load and load noise are reduced
4) The repeatability of clamping accuracy is very high, safe and reliable
5) Compared with the gasket and flange clamping method, the assembly and disassembly time is reduced by 90%.
6) Adjusting the distance between the 12 inches cut off wheel without relying on the spacer, the board width adjustment time is greatly shortened
