Quality & Factory
OEM capability depends on controlled process ownership and clear inspection evidence. Operating from Shenzhen and Dongguan, we coordinate precision machining, heat treatment, and inspection routes for global procurement programs.
In-House Manufacturing Processes

CNC Swiss Turning & Thread Grinding
CNC turning and thread-grinding routes are selected around lead accuracy, surface roughness, runout, and inspection evidence. This is critical for controlling motion quality in compact medical, robotics, and aerospace mechanisms.
Induction & Carburizing Hardening
Heat-treatment routes for 100Cr6, GCr15, 440C, stainless, or customer-specified steels are locked with hardness, case-depth, and surface-finish checks where the application requires them.
Quality Control Framework
Quality records are planned to reduce supplier-qualification risk for compliance-driven buyers. We align inspection packages to customer flowdowns, ISO 9001-style audit expectations, medical QMS records, aerospace documentation, and program-specific release criteria. For material-specific validations, see our engineering guide on 100Cr6 Roller Screw Components.

| Test Type | Equipment | Standards / Reports |
|---|---|---|
| Material Traceability | Spectrometer | EN 10204 3.1 Material Certificate (MTC) |
| Micro-structure & Hardness | Vickers / Rockwell Testers | Case depth and surface hardness validation |
| Dimensional Accuracy | Coordinate Measuring Machine (CMM) | Micron-level geometric tolerance reports |
| Non-Destructive Testing | Magnetic Particle Inspection | Surface crack screening report where required |
ISO 2859-1 / AQL Risk Sampling
Standard commercial orders can use ISO 2859-1 / AQL sampling, while higher-risk programs can define first-article or expanded inspection before quotation. From preload torque curves to lead accuracy charting, the required data package is agreed alongside the hardware scope.
Preparing a 10 mm Micro Roller Screw RFQ
A nominal diameter by itself is not enough to confirm fit or quote scope. Define the reference dimension, envelope, load and motion profile, and requested inspection records before supplier review.
Use the 10 mm size and drawing-based RFQ guideBuyer Evidence Package by Program Type
Procurement and quality teams can request different evidence levels by application risk. We align the inspection package before sample release so commercial quote, engineering validation, and supplier qualification use the same acceptance basis.
| Program Type | Typical Records | Decision Use |
|---|---|---|
| Humanoid robot pilot builds | First-article dimensions, preload torque, axial play, hardness, and lead accuracy trace. | Compare actuator samples and stabilize repeat-lot acceptance before scaling. |
| Medical or lab automation | Material traceability, surface finish, lubricant notes, cleanliness or packaging plan, and backlash report. | Support design-history and validation records without rebuilding samples later. |
| Aerospace mechanisms | EN 10204 3.1 MTC, heat-treatment lot, CMM report, hardness report, and customer flowdown checklist. | Give supplier quality and engineering teams a qualification package early in the RFQ process. |
Manufacturing Path by Product
- Ultra-Micro & Miniature RV uses micro turning, thread grinding, matched nut/roller inspection, and short-stroke lubrication review.
- Inverted Roller Screw (RVi) requires long internal thread grinding, nut concentricity control, and actuator-level rotor interface review.
- 10mm Inverted Roller Screw specifically evaluates manufacturing feasibility for compact 10mm actuators with complex nut concentricity.
- Recirculating & High-Stiffness Roller Screws add stiffness, support-bearing, buckling, and lubrication evidence to the production control plan.
Supplier Qualification & Factory Audits
We welcome OEM procurement teams to conduct rigorous supplier qualifications. Whether you require a physical plant tour or a virtual live-streamed audit of our CNC and CMM facilities, our engineering and QA teams are ready to provide full transparency.
