What are the gear grinding processes introduced by the small module gear processing manufacturers?

1. Material preparation: purchase qualified raw materials and outer diameter steel according to customer requirements.

2. Material cutting: cut steel according to the drawing requirements.

3. Turning: make tooth blanks according to the drawing requirements.

4. Semi-finished product inspection: the quality management personnel shall check whether there is any error between each dimension and the drawing.

5. Gear hobbing: hobbing the gear teeth on the gear hobbing machine.

6. Pulling tooth: pull the inner hole tooth of the pin workpiece on the broaching machine.

7. Gear planer: the workpiece that is not suitable for gear hobbing is processed on the gear planer.

8. Burr treatment: remove the burr in the process of gear tooth treatment by hand or corner machine.

9. Gear scraping: in order to meet the requirements of gear surface finish and tooth shape, the gear surface is scraped and finished on the gear scraping machine.

10. Drilling and milling: milling the gear in the form of drilling and tapping in the machining center.

11. Heat treatment (carburizing): In order to increase the gear hardness and improve the mechanical properties of the product, the workpiece is put into the carburizing furnace for heat treatment.

12. Heat treatment (high cycle): In order to increase the surface hardness of the gear and enhance the mechanical properties of the product, the workpiece is subject to high-frequency heat treatment.

13. Calibration: In order to ensure that the dimension requirements or grinding process are met, the outer diameter deviation of the shaft center after heat treatment is corrected on the calibration machine.

14. Sand blasting: in order to remove oil stains and enhance the mechanical properties of the gear surface, the workpiece surface after heat treatment is sandblasted.

15. Burr treatment: in order to improve the transmission power and reduce the transmission noise, it is necessary to effectively remove the edges and corners at the tooth end of the workpiece.

16. Meshing: In order to reduce the transmission noise, it is necessary to effectively remove the burr or debris on the workpiece teeth.

17. Internal research: In order to meet the requirements of its surface roughness and size, it is necessary to grind the inner hole of the workpiece.

18. External research: In order to meet the requirements of its surface roughness and size, it is necessary to grind the outer diameter of the workpiece.

19. Plane research: in order to meet the requirements of its surface roughness and size, it is necessary to grind the plane (end face) of the workpiece.

20. Tooth lapping: in order to meet the requirements of its surface roughness and tooth profile accuracy, the workpiece tooth surface needs to be lapped.

21. Finished product inspection: In order to ensure that the workpiece meets the requirements of the drawing, the quality control department carries out sampling inspection on the gear workpiece.

22. Cleaning: In order to remove the oil stain or other magazines on the surface of the workpiece, do a good job of anti-rust treatment and facilitate storage, it is necessary to clean the workpiece after the inspection of the finished gear.

23. Packaging: the cleaned products are packed and warehoused or shipped.

24. Warehousing: The packed gears are warehoused in the designated warehouse for shipment or inventory.
