For example, the strength of the heat-treated material is manipulated at the hrc hardness of 50, and the coarse tooth H cannot be used for Z. That will reduce the application life of the rotary file. Z can use diamond grinding head to do grinding work.

1. When the substrate has large deformation, inconsistent thickness, and large internal thread service, when there are doubts about the birth defects of the above substrate, there are cutting errors and omissions regardless of the type of machine and equipment used. Larger deformation of the base material will cause deviations in the two side angles, and large body holes will cause deviations in the diameter jump; inconsistent thickness of the base material will cause deviations in the back and front angles. If there is an excessively large pitch diameter of the accumulated thread, the quality of the woodworking saw blade Precision suffers from unoptimistic hazards.

2. The distribution of the inner hole of the mill is harmful to the inner hole of the mill. The quality of the inner hole of the aluminum alloy saw blade mill depends on the model structure and installation. The model adopts column cutting, and the advantages are as many as the use of hydraulic press for infinite fitness exercise. The management system of the number of cutting tools adopts V-shaped sliding rail and ball screw. The grinding wheel or arm adopts the lower knife to advance slowly, the knife retracts and retreats, and the clamping hydraulic cylinder Reconditioning industrial base, clever and firm branches, precise positioning of gears, precise positioning of woodworking saw blades, solid and fully automatic industrial bases, reckless focus point care, effective cooling and flushing, complete man-machine interface, high precision cutting, pure CNC grinder Effective overall planning; the first type is the current vertical type, such as China Taiwan and Japan models, the gear transmission has transmission gears and mechanical equipment gaps and horn-shaped rolling precision is poor, the clip has low stabilization, and the adjustment difficulty coefficient of the branch industry base is large. The tooth extraction distribution or firmness is poor, and there is no industrial base for cutting on the two sides of the plan and behind the fiddle. The deviation of the disease is large, the focus point is difficult to manipulate, and the mechanical equipment is damaged to ensure the precision.

3. Electric welding factors. During electric welding, the aluminum alloy has a large deviation to mild to moderate degree, which will harm the cutting precision. The composition has a large force on the grinding wheel and a small force on the other. The following factors are the same as the above factors. The prevention factors are not good for the occurrence of the sand wheel and other factors during cutting to avoid the harm.

4. The quality of the sand wheel and the overall width of the particle size distribution are harmful. Use the sand wheel to grind the aluminum alloy oral epithelial cells. Pay attention to the particle size distribution of the sand wheel. The particle size distribution is too rough to cause the sand wheel mark. Clogging is less cutting and easy to burn. The diameter of the sand wheel and the total width of the sand wheel are determined according to the length and width of the aluminum alloy or the bad tooth profile and the condition of each surface of the aluminum alloy. If the tooth shape is not the same, it must be purposeful to adopt the suitable standard sand wheel.

5. The cutting speed of the grinding wheel and the cutting pros and cons of alloy saw blades are completely related to the cutting speed of the grinding wheel. Generally, the cutting speed of coarse tooth F is 6mm/sec. This value cannot be overspeed, that is, each minute should be within 20 teeth, higher than If the cutting speed of 20 teeth per minute is too high, the disease will not be optimistic, or the uneven surface of the aluminum alloy sand wheel will damage the precision of the inner hole of the grinding wheel and waste the sand wheel.

6. The cutting speed of the grinding wheel. The particle size distribution of the grinding wheel has a constant meaning for the amount of cutting. Generally, the grinding wheel is considered to be 180# to 240#. The extreme amount is 240# to 280#, and 280# to 320 is not adopted. #, or adjust the speed of the knife.

7. Cutting industry base, all woodworking saw blades should be cut with the base material as the industrial base, not with the wound as the industrial base. The plan cutting industry base cannot be taken out, and the back and foot side production and processing industrial bases cannot be polished. Woodworking saw blades, the woodworking saw blade industry base is not careless in the three steps of cutting. When cutting the side corners, still carefully observe the thickness of the aluminum alloy. The cutting industry base is not the same as the thickness. With the change, regardless of the thickness of the aluminum alloy, the sand wheel industry base line should be maintained in a parallel line with the electric welding position when grinding the side. Otherwise, the focus of the disease will endanger drilling.

8. The gear allocation is not good and careless. Regardless of the structure of all gear grinding machines, the overall planning of the gear coordinate accuracy involves the quality of knife making skills. After the machine is adjusted, the gear needle is pressed on the effective part of the journal. It is also important to not have to move. When retracting the teeth, the claws should be dexterous and firm.

9. Clip distribution: The distribution of the clips is stable and firm, which is the main position of the quality of the sharpening skills. When all the sharpening skills are not properly distributed, the clips are a little loose, or the side grinding deviation is not optimistic and cannot be controlled.

10. Cutting stroke arrangement. Regardless of the cutting position of the woodworking saw blade, the cutting stroke arrangement of the grinding wheel is very important. Generally, the grinding wheel is required to exceed 1 mm of work or to withdraw 1 mm, otherwise it will harm other teeth.

11. Selection of program flow: general knife sharpening skills There are three different program flow choices for rough, fine, and milling machines and equipment. Depending on the product requirements, it is considered that the fine polishing program flow is used when the Z final grinding ruler side.

12. The quality of the inner hole of the cryo-fluid mill depends on the grinding fluid. A lot of tungsten, cobalt, emery wheel powder occur during cutting. Do not rinse the surface of the CNC blade immediately and clean the vent hole of the sand wheel. Method to polish the smoothness, aluminum alloy will be burnt if the refrigeration is not reached.

Two: The damage of aluminum alloy saw blade and the application life of many factors can not be careless!

①Coarse tooth L damage has all normal damages and abnormal damages. The CNC blade has obvious friction with the drilling material under ultra-high pressure, which temporarily causes the blade damage and passivation treatment. They are caused by the following doubts: A. Back blade damage The incidence is on the surface of the rake adjacent to the drilling, and when the back is damaged, it forms an edge surface that tends to zero. B. After the front cutting edge is damaged, the front cutting edge gets rid of the main drill cutting edge to form a crescent crater. This type of damage usually occurs when the plastic deformation material is drilled thick enough. C. Damage to the front, rear, left and right edges together. This type of damage is caused by the front edge crescent crater and the rear edge damaged edge surface.

② Abnormal damage: A. It is the overall planning or manufacturing technical composition of the focus point of the CNC blade. B. Material ductility, plastic deformation, ground stress, rotor dynamic balance and many other factors. C. Abrasion resistance of aluminum alloy, edge curling and base material rigidity, etc.

③The reason for the damage of the CNC blade: A. The cutting edge is not smooth and the cutting edge has groove marks, and the ratio of aluminum alloy strength and wear resistance to the strength of the drilled material is small. B. Bonding is damaged. Only when the focus point of the knife and the drilling plate are rubbed, the bonding occurs at a high temperature. C. Dispersion damage During high-temperature drilling, aluminum alloy elements and wood compounds are dispersed between each other to form organic chemical purification. D. Change and damage. The aluminum alloy and base material will change due to temperature changes or dynamic forces, which will result in the loss of unstable dynamic drilling. E. Air oxidation damages the oxygen in the air and the cobalt, tungsten, and titanium carbide in the aluminum alloy. F. Other damages, due to the impact of the drilling process, insufficient rigidity of the tooth seat, ductility or plastic deformation offset, excessive thermal stress during electric welding, and mechanical equipment factors.

④ Damage process of aluminum alloy saw blade. The surface roughness is very large, and the diameter is large. The aluminum alloy blades are not operated together, some are too heavy and some are too light. If the ruler side is too small, there will be some heat dissipation in each drilling, and the grinding of the left and right corners of each aluminum alloy is inconsistent. During drilling, some aluminum alloy metallographic analysis is allocated in the cutting edge to cause changes.

⑤ Factors that endanger the life of aluminum alloy saw blades. The smaller the heat transfer coefficient, the worse the heat removal efficiency of the CNC blade. Therefore, it is difficult and doubtful to deal with the heat removal of aluminum alloy saw blade dry drilling. In order to have the effective use of CNC blades, a few main parameters can be regarded as guaranteeing their application life. The cutting speed of the enlarged ruler side is reduced, the temperature is lowered, and the compressive strength of the excessive ruler side is reduced. The cutting edge angle decreases after the back, and the cutting amount is too slow. Among them are still full of opposites, and there are still many factors that naturally endanger CNC blades.

⑥Aluminum alloy saw blades improve the application life rule, and the base material should be made of aluminum alloy steel as much as possible to make the base material not easy to deform when the temperature of the base material is at 300°, the ground stress is well removed, and the overall planning of the heat extraction groove of the tooth seat is scientifically rationalized. . Wound thickness-index 0.8~1=thickness of base material. Alloy equipment does not need to be too small, thin, or short. Electric welding must strictly consider the compressive strength, temperature, ground stress and technology of electric welding, technicality of sharpening skills, grinding fluid, raw material and particle size distribution of diamond sand wheel, rigidity of machinery and equipment, and machinery The precision of equipment, the amount of tool under grinding speed, and the life of CNC blades only need a valid standard value to reduce the production cost and develop the application life. For example, the life span of the economic development method used in production will inevitably be reduced, and the output power will develop purely.
