1.Shorten the product manufacturing process chain and improve production efficiency
Turn-milling can achieve a single load to complete all or most of the processing processes, thus greatly shortening the product manufacturing process chain, can significantly improve production efficiency.
2.Reduce the number of clamping, improve the machining accuracy
The number of card loading is reduced to avoid the accumulation of errors, and the turn-milling equipment has the function of online detection, which can realize the in-place detection and precision control of key data in the manufacturing process, so as to improve the processing accuracy of the product.
3.Reduce footprint, reduce production costs
It can effectively reduce the overall production operation and management costs.
A:Multi-task turn-mill can process materials including copper, iron, aluminum alloy, stainless steel, iron dragon and so on.
A: Parts most suitable for turn-mill machining are primarily those requiring simultaneous turning and milling processes, featuring complex structures (e.g., shafts with keyways/pin holes/curved surfaces, irregular rotational parts), having high demands for precision (such as coaxiality and geometric tolerances) and lead time, or made of difficult-to-machine materials (titanium alloy, stainless steel 316L, etc.) with small-to-medium batch sizes. These parts can be integrally processed in one clamping, significantly reducing positioning errors, improving efficiency, and shortening lead times.
