With the continuous advancement of production technology, the quality of customized gear processing has also greatly improved. However, if not careful during the machining process, errors can still occur. What are the reasons for these errors in gear customization machining?
1. The accuracy of the machine tool transmission chain is not high, and during operation, it exhibits vibration or impact, which affects the instability of the machine tool transmission.
2. The contact between the worktable spindle and the conical guide surface of the worktable shell does not meet the requirements. The conical guide surface is hard to touch, and the worktable rotates heavily. Vibration occurs during work. Causing errors during processing.
3. Make the blade mechanism malfunction and return the blade to scrape the surface of the workpiece.
4. Poor quality of gear hobbing blade grinding.
5. Excessive feed rate causes the gear cutter to cut the rack in a timely manner, resulting in rough surface of the rack.
6. The gear rack blank cannot be installed properly, resulting in vibration during cutting.
7. The cutting fluid is dirty or has been flushed into the cutting tooth groove. Causing the surface quality of the rack to be unqualified.
