We Don’t Sell Machines — We Solve Machining Problems

Lonfu-Tech CNC — precision machining process & machine solution provider

You are asking whether we can hold that bore, that journal, that face—under real coolant, real chips, real shifts. We anchor on high precision, process implementation, difficult-part resolution, and training with after-sales so the capability stays on your floor.

Precision machined parts — shafts, sleeves, and journal-class components
High precision spindle and spindle-class features
Mirror turning — ultra-precision optical surfaces

China machine expertise → export mindset

  • Application-first specs for international acceptance
  • Documentation habits that survive audits
  • Training so capability stays local to your plant
Why we’re different from pure traders

From Requirement to Stable Production

Machine selection follows process evidence—not the other way around.

01

Drawing → Tolerance → Process

We work backward from the feature control frame: what must be true for your assembly and inspection method?

Datum strategy Stock & sequence Gauge correlation Risk notes
02

Machine + Tooling + Parameters

Recommendation bundles include why this stiffness, wheel, or coolant direction fits your class of parts.

Application engineering Trials plan Buyoff criteria Run-off support
03

Training & After-Sales

Commissioning without capability transfer fails in month two—we plan against that explicitly.

Send the Drawing — We’ll Respond With Process Sense

The fastest way to judge fit is not browsing brochures; it’s a structured look at tolerance, material, and batch reality.
