Nine processes under one roof, so a part that needs turning, hardening, grinding and EDM does not travel between four suppliers.
Nine processes under one roof, so a part that needs turning, hardening, grinding and EDM does not travel between four suppliers.
Most precision parts are not made by one process. They start on a lathe, go through heat treatment, come back to a grinder, then get a wire-cut profile or a sunk cavity. Every handover is a chance to lose a datum, and every supplier is a separate argument about who moved it.
Because all nine processes run in the same building in Fenggang, the part stays on one datum chain and one engineer stays accountable for it. Below is what each department actually does, and what it is not the right answer for.
The nine processes
Choosing a process
| If the part is | The process is usually | What changes the answer |
|---|---|---|
| Round, with a concentric bore | CNC turning, mill-turn for cross features | Whether the features stay concentric without a second setup |
| Prismatic, with pockets and holes | CNC milling, 4- or 5-axis if angled faces appear | How many setups the geometry really needs |
| Tooth forms, splines or timing features | Hobbing or shaping, ground after hardening | Internal or external, and whether the part is hardened |
| Hardened, with a running surface | OD or ID grinding after heat treatment | Stock left for grinding and distortion in the furnace |
| Hardened with sharp internal corners | Wire EDM | Corner radius the wire can physically leave |
| Deep, square-bottomed or ribbed | Sinker EDM with a shaped electrode | Depth-to-width ratio and flushing |
| A plastic part at volume | Mould making, then injection moulding | Whether the volume ever pays back the tooling |
We do not run Swiss-type turning below 4 mm bar, we do not do heat treatment in-house, and we do not claim cleanroom assembly. Where a job needs those, we say so at quotation instead of learning it halfway through.
