Li Dexin saw blade grinding machine manufacturers introduce grinding gear machining precautions?
 
 
 
First, Li Dexin saw blade grinding machine manufacturers introduce grinding machine machining program editing principles
 
 
 
 1. Under normal circumstances, the workpiece material with larger modulus is more difficult to grind the workpiece with higher precision, and the smaller single step tool and slower workpiece rack moving speed are selected. The material with a small modulus is easy to grind, and the precision is low. The larger feed rate and the faster moving speed of the workpiece holder are selected.
 
 
 
 2. If there is displacement in the machining program, the amount of feed in the stroke with displacement will decrease, the speed will slow down, and the amount of feed of 0.1 mm or more will be left after the displacement.
 
 
 
 3. In the machining program, the total number of strokes of the upper retracting knife is selected as the odd number, and the total number of strokes of the lower retracting knife is double, and the direction of the control retracting direction is consistent with the direction in the program.
 
 
 
 4. Under normal circumstances, the workpiece with more than 40 teeth, the grinding wheel working speed is 1500r/min, and the height is 1650r/min. The working speed of the workpiece grinding wheel below 40 teeth is appropriately reduced, and the low rotation speed is 1000/min.
 
 
 
 5. Sometimes in order to process high-precision workpieces, the coarse grinding can be separated and two machining programs can be written. The rough grinding program reflects the efficiency and the precision grinding program ensures the accuracy.
 
 
 
Second, Li Dexin saw blade grinding machine manufacturers introduce grinding gear machining wheel dressing
 
 
 
 1. The single-stepping tool of the grinding wheel is generally 0.03mm. When the modulus is large, the amount of cutting is appropriately reduced. When the modulus is small, the amount of cutting is appropriately increased.
 
 
 
 2. In order to improve the machining efficiency, the amount of the feed is increased during the one or two strokes of the trimming, and the sharpness of the grinding section of the grinding wheel is increased. Sometimes, in order to improve the machining accuracy, the amount of the feed is reduced during one or two strokes of the trimming. , let the grinding wheel grind the cross section to get a better shape.
 
 
 
 3. When grinding the wheel for the first time, you must first take a trip, in case the wrong number of the hanging wheel or the wheel is wrong.
 
 
 
 4. It is recommended that the user use 80K grinding wheel for small modulus and 80J grinding wheel for large modulus.
 
 
 
 5. The amount of the amount to be repaired after the grinding wheel is used up is determined by the modulus of the workpiece, the material of the workpiece and the grinding wheel, and the precision of the machining requirements. The theoretical value is the modulus multiplied by 0.1 mm, and the small amount of each trimming value is 0.25 mm.
 
 
 
 6. After correcting the tooth profile of the grinding wheel, the grinding wheel of the hand plate should not move after the file is finished.

Third, Li Dexin saw blade grinding machine manufacturers introduce grinding gear machining grinding notes:
 
 
 
 1. During the operation of the machine tool, the separation mechanism must be opened to avoid excessive cooling of the oil, and the increase in viscosity affects the cooling effect.
 
 
 
 2. The cooling nozzle position is fixed in the middle of the grinding wheel, and the upper and lower sides are adjusted to ensure that cold oil is sprayed on the processing area.
 
 
 
 3. The machine cannot touch any button on the operation panel during the grinding cycle.
 
 
 
 4. After the initial position of the grinding wheel is determined, the override of the handwheel is turned off.
 
 
 
 5. It is not allowed to press the balancer during machine work.
 
 
 
 6. The modulus hanging wheels are neatly discharged to prevent bumps.
 
 
 
 7. After the grinding is finished, the grinding wheel should be oiled for a long time to prevent the vibration of the next grinding wheel due to unbalance.
 
 
 
 8. Ensure that the machine bed is clean and free of debris, ensure that the oil return is smooth, and prevent oil mixing. When adjusting the installation angle of the workpiece, pay attention to the position of the wire to prevent it from being damaged. After adjusting the angle, the oil return line below the workpiece frame should be leveled to avoid poor oil return and oil mixing.
 
 
 
 9. When the grinding wheel is trimmed, do not open the oil as much as possible. The grinding wheel cover is repaired after the tooth shape is finished. The oil is smashed downwards and then the outer circumference of the grinding wheel.
 
 
 
 10 When changing the specifications, make sure that the gear parameters are correct. The X-axis starting position should be confirmed repeatedly and the action should be slow.
 
 
 
Four: Li Dexin saw blade grinding machine manufacturers introduce grinding machine processing machine maintenance:
 
 
 
 1 Run for 15 minutes before starting work every day, and simmer for 15 minutes before shutting down.
 
 
 
 2 Clean the separation cylinder every day to check the tank pressure and the wheel box lubricant.
 
 
 
 3 Clean the accessory filter net regularly.
 
 
 
 4 Clean the chucks regularly.
