1. The base body is deformed greatly, the thickness is inconsistent, and the inner hole tolerance is large. When there is a problem with the above-mentioned substrate congenital defects, there is a grinding error regardless of the type of equipment used. The deformation of the base body is deviated from the two side angles; the thickness of the base body is inconsistent with respect to the back angle and the rake angle. If the cumulative tolerance is too large, the quality and accuracy of the saw blade are seriously affected.

2. The influence of the grinding mechanism on the grinding teeth. The alloy circular saw blade grinding teeth is good or bad in the structure and assembly of the machine. At present, there are about two types of models in the market: one is the German type of floating ink. This type adopts vertical grinding and pinning. All the advantages are hydraulic stepless movement. All feed systems use V-shaped guide rails and ball screw rods. The grinding head or boom adopts the advancement of the feed, the retraction is retracted, and the clamping cylinder is adjusted. The heart and the support piece are flexible and reliable. MMSonline.com.cn is copyrighted, the tooth extraction is accurately positioned, the saw blade positioning heart is firm and self-centering, the angle is adjusted at any angle, the cooling and flushing is reasonable, the man-machine interface is realized, the grinding precision is high, and the pure grinding machine is rationally designed. The second type is the current horizontal type, such as the Taiwanese model of Japan. The mechanical transmission has gear and mechanical clearance. The sliding precision of the dovetail is poor, the stability of the clip is low, the adjustment of the support core is difficult, the tooth extraction mechanism or reliability is poor, and the two sides of the plane are The left and right rear corners are not ground in one heart, resulting in large deviations, difficult angle control, and large mechanical wear to ensure accuracy.

3. Welding factors. When the welding is performed, the deviation of the alloy is large, which affects the grinding precision. When the grinding head is pressed, the pressure is small, the back angle also produces the above factors, the welding angle is poor, and the human inevitable factors are all factors such as the grinding wheel during grinding. Produce unavoidable effects.

4. Influence of grinding wheel quality and particle size width. When using the grinding wheel to grind the alloy sheet, the plastic industry network copyright, pay attention to the grinding wheel particle size, the grain size is too coarse grinding to produce the wheel wheel trace, the grinding wheel is fine and easy to block the grinding amount and easy to burn the knife. The diameter of the grinding wheel and the thickness of the 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 a chamfer or front angle grinding wheel that can grind different tooth shapes arbitrarily. Specification grinding wheel.

5. Grinding head feed speed. The grinding of the alloy saw blade is completely determined by the feed rate of the grinding head. Generally, the feed rate of the alloy circular saw blade should not exceed this value at 0.5 to 6 mm/sec. That is, it should be within 20 teeth per minute, exceeding every minute. If the feed speed of 20 teeth is too large, it will produce serious knife or burnt alloy. The grinding wheel will produce convex and concave surface, which will affect the grinding precision and waste the grinding wheel.

6, the grinding head feed amount, the choice of grinding wheel size is extremely important for the amount of feed. General grinding wheel is recommended to use 180# to 240# extreme quantity selection 240# to 280# not to use 280# to 320#, otherwise the feed rate should be adjusted.

7, grinding the heart. All the saw blades are grounded with the base body instead of the heart of the knife edge. The surface grinding heart cannot be taken out. The back corner and the front corner cannot be ground with a sawing blade. The three process saw blades are ground. Can not be ignored. When grinding the side angles, the thickness of the alloy is carefully observed. The thickness of the grinding heart changes accordingly. Regardless of the thickness of the alloy, the core 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.

8, the tooth extraction mechanism can not be ignored. Regardless of the structure of any gear grinding machine, the accuracy of the tooth extraction coordinate design is designed to the quality of the sharpening. When the machine is adjusted, the needle is pressed at a reasonable position on the tooth surface. It is also extremely important to move the tooth. When the tooth is retracted, the tooth extraction claw should be Flexible and reliable.

9. Clip mechanism: The clip mechanism is firm, stable and reliable. It is the main part of the sharpening quality. ZAOCHE168.com is the copyright. Any clip mechanism should not be loose when grinding, otherwise the grinding teeth will be out of control.

10. Grinding stroke. Regardless of the grinding of any part of the saw blade, the grinding head grinding stroke is very important. It is generally recommended that the grinding wheel exceeds the workpiece by 1 mm or exits 1 mm, otherwise the tooth surface will produce a two-sided cutting edge.

11. Program selection: Grinding knives are generally set with three different procedures: coarse, fine and abrasive. Depending on the product requirements, it is recommended to use the fine grinding program when grinding the front corner.

12, the cooling fluid grinding is determined by the grinding fluid. When grinding, a large amount of tungsten crucibles and diamond powder are generated. The surface of the cutter is not washed in time and the pores of the grinding wheel are cleaned, so that the surface grinding tool cannot be polished, and the alloy is burned without sufficient cooling.
