CNC Thread Grinding Route
The core manufacturing problem is grinding long internally threaded nuts for inverted roller screws. The route reviews temperature control, grinding allowance, pitch error, and inspection access before sample machining.
Company Profile
Inverted Roller Screw Manufacturing Team
Inverted Roller Screw provides application-driven DFM review, custom tooling, and batch-traceable production for global OEM engineering teams.
We are a high-end manufacturing facility based in Shenzhen and Dongguan, China, operating under Inverted Roller Screw We support global industrial buyers with rigorous engineering collaboration, stable production processes, and export-oriented delivery execution.
Heavy Shaft Process Options
For heavy actuator shafts, the process route is selected by load, material, heat treatment, end features, and required inspection package. Buyers should confirm whether forged, turned, or ground blanks fit the program requirement.
Heat Treatment Control
Material and heat treatment are reviewed against hardness, distortion, core toughness, corrosion, coating, and document requirements. The accepted route is tied back to lot records and inspection evidence.
Manufacturing Facilities (Shenzhen & Dongguan)
Our precision manufacturing operations are split between Shenzhen and Dongguan, delivering localized supply chain integration under the Inverted Roller Screw entity. Capability discussions are scoped by drawing, process route, inspection package, and buyer qualification requirements.
CNC Machining & Thread Grinding

Capability Matrix for Buyers
| Capability Area | What We Support | Buyer Value |
|---|---|---|
| Product Coverage | Inverted roller screws, micro screw sets, actuator screws, nuts, shafts, rollers, and timing rings | One-vendor coordination across custom compact actuator programs. |
| Customization | OD, lead, stroke, preload, shaft ends, long nut geometry, material, heat treatment, and coating adaptation | Reduces packaging, life, and sample rework risk. |
| Validation | Sample workflow with measurable acceptance criteria | Supports decision-ready prototype gates. |
| Quality & Delivery | Process checkpoints, traceability, export execution planning | Improves repeat-order predictability and audit readiness. |
What We Want Buyers to Verify
Industrial buyers should not rely on brand claims alone. The most useful qualification discussion is built around evidence that can be attached to a project file.
| Question | Evidence to Request | Where to Continue |
|---|---|---|
| Can the long nut be manufactured consistently? | Lead/profile report, runout/coaxiality check, roughness record, hardness record, and matched-set validation notes. | Internal Thread Grinding |
| Can the design move from prototype to small batch? | Frozen drawing revision, CTQ list, material certificate, heat number, first-article report, and change-control plan. | OEM Capabilities |
| Can procurement approve overseas supply? | Certificate scope, inspection report, CoC, traceability package, packaging plan, and export documentation scope. | Quality & Inspection |
