Why engineers use JunYi for CNC machining
Instant quoting & quick DFM
We are able to send you a quote 20 minutes or less after received your RFQ on working time for prototypes that less than 10 items on request. If we got RFQ before 10a.m, we'll provide quotes at the same day for prototypes. Normally quotes for tools and production will be provided within 48hours. If you have a plan to get your project move forward, we'd like to provide a quick DFM for your reference free of charge.

Available CNC machining services
| Name | Description |
|---|---|
| CNC Milling service | CNC milling is a subtractive manufacturing process that rapidly removes material from metal or plastic blocks to produce precision parts with tight tolerances. |
| CNC Turning service | CNC turning produces parts with cylindrical features by removing material from metal or plastic rods using cutters, center drills or live tooling. |
| 5-axis CNC machining | 5-axis CNC machines can produce parts with complex geometries and increase productivity by minimizing the number of machine setups. |
