Strong tooth scraping is a continuous cutting process that can be completed in one clamping operation. This process takes much less time to produce a gear than other techniques, usually four times faster than gear hobbing. How could you not understand this practical processing technique? Shangying Transmission will decrypt for you.
1、 What is strong tooth scraping
Strong tooth scraping essentially combines two processes: rolling milling and gear hobbing. Gear hobbing requires the machining of gear teeth through repeated travel movements, which is a non machining return motion after cutting, while strong tooth scraping eliminates this unnecessary non cutting time. Unlike the wire cutting process, the strong scraping teeth only require one machining and clamping, ensuring higher flexibility and quality. In contrast, the cutting tool processing cycle of the lathe process is long and the production flexibility is low, thus becoming a bottleneck. The concept of strong tooth scraping was conceived as early as 1910, and since then, people have recognized that the production efficiency of tooth scraping may be much higher than that of gear hobbing when processing most internal gears. However, only after the machining center became more robust and rigid, and the synchronous spindle was born, the application of strong scraping teeth was realized. From its initial concept to over 100 years later, powerful scraping has finally become a practical productivity, thanks to the advancement of machine tool technology. For many types of internal gear applications, strong tooth scraping is a significant improvement in machining speed, cost, and quality.
2、 What are the special requirements for strong scraping teeth?
Strong tooth scraping requires the machining center and spindle to be able to cope with highly dynamic machining conditions; It also requires a fully synchronized spindle. This means that if the spindle of the part slows down, the tool spindle can immediately respond. In the strong scraping process, the tool shaft and gear shaft are interlocked, and the angle formed by the tool and gear shaft determines the production efficiency. The larger the angle, the higher the production efficiency. Appropriate software is also crucial for machine tool control, as they can optimize the efficiency of gear scraping processes.
3、 What are the requirements for the tool system for strong tooth scraping?
Strong tooth scraping requires cutting tools with higher production efficiency. Adjustable cutting tools can improve production efficiency and reduce the use of integral cutting tools in precision machining. This also means reducing the grinding frequency of precision machining tools.
4、 What other parts can the strong scraping technology be used to produce?
Strong tooth scraping is suitable for producing internal gears, shafts with internal/external teeth, splines, or individual gear parts with external and internal splines. It is also suitable for pre hardening of internal gears and hard working of various types of gears.
