The Non-negligible Factor Of Diamond Saw Blade in Grinding

The matrix deformation is large, the thickness is inconsistent, and the tolerance of inner hole is large. When the above matrix congenital defects exist, there will be grinding errors regardless of the type of equipment used. Large matrix deformation causes deviation of bilateral Angle. Inconsistency of matrix thickness will cause deviation of back Angle and front edge Angle. If accumulated tolerance is too large, the quality and accuracy of saw blade will be seriously affected.
Welding factor. During welding, the alloy pair deviation is large, which affects the grinding accuracy, resulting in large pressure on one side of the grinding head and small pressure on the other side. The rear Angle also produces the above factors. The welding Angle is poor, and the human unavoidable factors have an unavoidable impact on the grinding wheel and other factors.
Influence of grinding wheel quality and grain size width. When selecting the grinding wheel to grind gold pieces, pay attention to the grinding wheel grain size. If the grain size is too coarse, the grinding wheel will cause the grinding wheel trace. The grinding wheel with fine grain size is easy to block the grinding amount and easy to burn the knife. The diameter of grinding wheel and the width and thickness of grinding wheel are determined according to the length and width of the alloy or the different tooth shapes and the various surfaces of the alloy. It is not possible to grind different tooth shapes arbitrarily with the same specifications of the grinding wheel at the back Angle or the front Angle, so it must be targeted to choose the suitable specifications of grinding wheel.
Grinding head feed, the selection of grinding wheel grain size is very important to the feed amount. Generally, it is recommended to choose 180 # to 240 # for grinding wheel, and to choose 240 # to 280 # in an extreme amount, not 280 # to 320 #, otherwise the feed speed should be adjusted.
Grinding center. All the saw blades should be centered on the matrix instead of the cutting edge. The surface grinding center can not be taken out, and the processing center of the rear Angle and front Angle can not be used to grind a saw blade. The center of the saw blade can not be ignored in the grinding three processes. When grinding the side Angle, the thickness of the alloy is still carefully observed, and the grinding center changes with different thickness. No matter what the thickness of the alloy is, the center line of the grinding wheel should be kept in a straight line with the welding position when grinding the surface, otherwise the Angle difference will affect the cutting.
Tooth pulling mechanism can not be ignored. No matter how the structure of any gear grinding machine, the accuracy of tooth extraction coordinate design to the sharpening quality, in the adjustment machine, the tooth extraction needle press in a reasonable position on the tooth surface, and do not move is extremely critical, tooth retreat, tooth extraction claw should be flexible and reliable.
Clamping mechanism: clamping mechanism is firm, stable and reliable, is the main part of sharpening tool quality, any sharpening tool clamping mechanism should not be loose, otherwise grinding tooth deviation seriously out of control.
Grinding stroke. No matter grinding any part of the saw blade, the grinding stroke of the grinding head is very important. It is generally required that the grinding wheel should exceed the workpiece by 1mm or withdraw by 1mm, otherwise the tooth surface will produce a two-sided blade.
Program selection: Generally there are three different programs for grinding, including rough, fine and grinding. Depending on the product requirements, it is recommended to use fine grinding program when grinding the front Angle.
The coolant grinding is determined by the grinding fluid. During grinding, a large amount of tungsten tridges and emery wheel powder are produced. If the tool surface is not washed and the porosity of the grinding wheel is cleaned in time, the surface grinding tool cannot grind out the finish, and alloy will be burned without sufficient cooling.
Influence of gear grinding mechanism on gear grinding. Diamond saw blade grinding is good or bad in the structure and assembly of the model, the current market is about two types of models: one is the German Furmer type. The type of vertical grinding pin, the advantages of all the hydraulic stepless movement, all the feed system uses V-shaped guide rail and ball screw work, grinding head or arm using the feed slow, fast back, clamping cylinder adjustment center, support flexible and reliable, tooth extraction accurate positioning, diamond saw blade positioning center firm automatic center, arbitrary Angle adjustment, cooling and washing reasonable, To achieve man-machine interface, high precision grinding pin, reasonable design of pure grinding machine; The second type is the current horizontal type.
Feed rate of grinding head. Diamond saw blade grinding is completely determined in the grinding head feed speed, general alloy circular saw blade feed speed in 0.5 to 6 mm/s can not exceed this value. That is, it should be within 20 teeth per minute. If the feed speed exceeds 20 teeth per minute, serious nodules or alloy burning will occur, and the grinding wheel will produce convex and concave surfaces, which will affect the precision of grinding teeth and waste the grinding wheel.
