The CNC gear hobbing machine has a wide range of applications, which can be used for batch, small batch, and single piece production and processing of cylindrical gears and worm gears, as well as drum gears with certain parameters. It can also be used for continuous indexing and hobbing of 6 teeth and short spline shafts with a length of less than 300 and more using spline hobbing cutters. Sprocket hobbing cutters can also be used for hobbing sprockets. When processing cylindrical gears, reverse milling and forward milling hobbing can be used, The method of axial feed (vertical feed) is used to process the full tooth width. CNC hobbing machines use radial feed for hobbing ordinary worm gears. When CNC hobbing machines process spline shafts and sprockets, the adjustment and processing methods of the machine tool are the same as when processing cylindrical spur gears, which can bring certain help to the production of various industries
Operating procedures for CNC gear hobbing machines:
1. Operators should conscientiously achieve the "three good" (good management, good use, and good repair) and "four skilled" (proficient in use, maintenance, inspection, and troubleshooting)
2. The operator must be familiar with the structural performance, transmission principle, and processing application program of this equipment, and can only operate independently after passing the exam and obtaining an operation certificate
3. Operators must comply with the "Five Disciplines" for using equipment and the "Four Requirements" for maintaining equipment
4. Operators should always inspect the equipment according to the requirements of the "patrol inspection content"
5. Strictly follow the oil requirements of the equipment for refueling, and achieve the "five fixed" lubrication (fixed time, fixed point, fixed quantity, fixed quality, and fixed person)
6. It is strictly prohibited to move or damage the warning signs on the machine tool
7. When multiple people operate, they should coordinate and coordinate with each other
8. It is strictly prohibited to overload or use equipment beyond specifications
9. When the CNC gear hobbing machine is stopped for more than eight hours, the hydraulic lubrication of the machine tool should be started for 5-10 minutes first, and then manually operate each motion axis to check if each part operates normally; Confirm normal operation, good lubrication, and no alarms before starting work
10. The tool must be installed correctly before work
11. The contact surface between the inner hole, end face, spindle, and washer of the cutting tool should be clean and properly matched
12. If the specifications and taper of the cutting tools do not match, they must not be clamped
13. The clamping tool must be tightened
14. When machining sector gears, it is necessary to balance and balance the workbench
15. Before work, the cutting amount should be reasonably selected based on the material, technical parameters, and tool material of the workpiece. The machining program should be correctly written and verified to be correct before trial cutting and workpiece processing can be carried out
16. When multiple workpieces are piled up for cutting, the contact surfaces should be flat and clean, and there should be no debris such as iron filings
17. When lifting (unloading) workpieces, safe lifting tools and methods must be selected based on the weight and shape of the workpieces, and they must not collide with the machine tool
18. The clamping workpiece should be securely fastened and not loose
19. When cutting gears with different helical angles, the tool holder should be tightened firmly after turning
20. When using automatic tool setting, pay attention to lowering the gear position of the multiplier switch, and do not shift gears during equipment operation
