Comparison of processing advantages of thread rolling head
Comparison of processing advantages of thread rolling head
For the processing of external threads, there are three main processing schemes on the market:
The commonly used processing scheme is thread turning tool processing, as well as thread rolling machine processing and thread rolling head processing.
However, where are the advantages and disadvantages of the three processing methods? Please see the comparison in the following table. I believe you will have a more intuitive judgment on the three external thread processing methods.
Comparison of thread processing technology | |||
Process name | Turning Thread | Wire rolling machining | Thread rolling |
Investment goods | Threaded turning tool bar + threaded blade | Wire rolling machine + wire rolling wheel | Rolling head + rolling wheel |
Processing mode | Machining on turning | Special machine single process processing | Machining on turning |
Consumables cost | 0.06~0.1 | 0.02~0.05 | 0.02~0.05 |
Processing time | 15s | 4s | 2s |
Whether the operation needs to be transferred | Unwanted | Want | Unwanted |
Is the geometric tolerance guaranteed | Stability guarantee | Instable | Stability guarantee |
Is it necessary to increase the site | Unwanted | Want | Unwanted |
Increase or decrease in personnel | Unwanted | Want | Unwanted |
Thread roughness (stainless steel 316) | Ra1.6 | Ra0.8 | Ra0.8 |
Increased thread strength | Unable to improve | Increase20%~35% | Increase30%~45% |
Are there any burrs | Burr | No burr | No burr |
Process stability | Instable | Instable | Stable |
Will strip iron chips be produced? | Yes | No chip | No chip |
The highest accuracy standard for machining threads | 4h | 4h | 4h |
Can automation be used | Risk of scrap iron handling | Yes | Yes |
Automation investment | 100 thousand | 200 thousand | 100 thousand |
Add equipment | No increase | Increase | No increase |
Single process efficiency improvement | Nothing | 73.33% | 86.67% |
Economical processing technology | - | - | OK |
To sum up: the advantages of thread rolling with thread rolling cutter in batch processing are still obvious!
