Tolerances

You need to know how exact your parts must be. Some jobs, like in aerospace or medical, need very tight tolerances. This means the size must be almost perfect, like ±0.001 inches or even less. This helps parts fit right and work safely. For example, implants and airplane parts need to be measured very carefully.

Tongyu can make parts with tight tolerances. They can do ±0.005mm for turning and ±0.01mm for milling. This is good for projects that need high accuracy.

Volume

Think about how many parts you need. Some projects just need a few test pieces. Others need thousands for big orders. Here is a simple guide:

• Prototyping means making 1–10 pieces. This is good for trying out ideas.

• Low volume is 10–100 pieces. This is for small batches or test runs.

• Mass production is 100–10,000+ pieces. This is for making lots of parts.

Tongyu can help with both small and big orders. You can order more as your project grows.

Deadlines

You should plan when you need your parts. How long it takes depends on how many you want and how hard they are to make. For example:

If you need parts fast, some cnc machining services, like Tongyu, can work quicker. Always check if your provider can rush your order when you need it soon.
