OEM Manufacturer Sewing Machine Parts Investment Casting - Machining Services – Daohong

High Precision Custom CNC Metal Machining Services

Our experienced machinists and versatile machines are well equipped to tackle even the most complex precision machined metal components. From smaller volumes on our  mills machine and lathes machine to high volumes available from Citizen automatic Swiss-style machining, along with our in-house deburring and mechanical polishing capabilities, we are ready to machine your turned parts. Our multi-axis Chmer EDM equipment adds wire-cut electrical discharge machining capability to the precision machining services we offer.

Automatic Precision CNC Machining

Years of precision CNC machining expertise and automatic machining equipment combine to make producing your high-volume, complex parts possible.  we can perform turning, boring, drilling, hexing, milling, polishing, and slotting, as well as threading and tapping. We are skilled in precision machining of ferrous and light alloys, with a specialty in stainless steel.

Wire EDM Machining Services

Our vast experience in the production of high-precision small parts combined with our Chmer equipment enables us to deliver wire EDM machining services that meet exacting design standards. Whatever your industry or application, our skilled machinists and high-quality automated process is ready to produce the parts you need, to the exact specifications you require and the highest Cpk and Ppk process results.

Multi-Axis CNC Mills, Lathes, And EDM Machining Centers

When we combine our precision small diameter in-feed and through-feed grinding capabilities and our cut-to-length expertise with our modern mills and lathes, our skilled and experienced machinists have a huge advantage producing precise yet economical micro diameter machined parts. We are able to add complex features to tiny parts we have already cut to length and ground that would be impossible to efficiently produce from traditional bar stock fed machining centers alone. These same multi-tool and live tooling equipped turning centers also allow us to produce conventional parts when needed.
