Drawing-based micro roller screw, inverted roller screw, and miniature actuator component integration for prototype-to-small-batch OEM programs.
Use the OEM integration path when a catalog roller screw is not enough: the actuator package needs custom shaft ends, a non-standard nut interface, controlled preload, documented inspection evidence, or a prototype route that can become a repeatable small-batch process.
Choose standard micro RV for compact screw/nut sets, inverted RVi for rotor-integrated packages, and recirculating or high-stiffness designs for fine-lead or high-force axes.
Risk if missed: Starting from a preferred part number without checking actuator packaging can create a sample that meets catalog data but fails assembly review.
Clarify which team owns shaft-end machining, nut housing geometry, anti-rotation features, bearing seats, and coupling details.
Risk if missed: Unassigned interfaces cause late drawing revisions and make sample acceptance hard to interpret.
Set the required inspection report level before quotation: engineering sample notes, first-article records, AQL sampling, or expanded inspection.
Risk if missed: Adding documentation after price lock changes cost, lead time, and sometimes manufacturing route.
| Program Metric | Typical Range | Procurement Value |
|---|---|---|
| Prototype lead time | 4-6 weeks after drawing and acceptance criteria lock | Keeps hardware teams moving without hiding the dependency on final geometry, material, and inspection scope. |
| Practical diameter range | 1.5-12 mm micro RV, 5-20 mm inverted RVi screw OD targets | Lets buyers screen whether the supplier is suitable for finger-scale, pump-scale, or compact joint actuator programs. |
| Customization scope | Shaft ends, flats, grooves, flanges, nut housing, anti-rotation features, and matched assemblies | Most OEM failures happen at the interface, not at the nominal thread size. |
| Release evidence | Material certificate, hardness, lead accuracy, axial play, preload torque, CMM dimensions, and packaging record | Gives engineering and procurement a shared basis for sample sign-off and repeat-order control. |
| Capability | Evidence | Buyer Value |
|---|---|---|
| DFM and drawing review | Marked-up drawing, open-issue list, tolerance-risk notes, and proposed control characteristics. | Makes hidden integration risks visible before prototype machining starts. |
| Micro machining and thread process control | Process route covering Swiss turning, thread grinding or rolling, heat treatment, finishing, and matched assembly checks. | Connects the quoted geometry to an actual manufacturing path instead of a generic custom promise. |
| Prototype-to-pilot traceability | Material lot, heat-treatment record, lead accuracy report, preload torque window, and revision-controlled acceptance checklist. | Lets the buyer reuse approved sample criteria for pilot and repeat lots. |
Step 1
Architecture recommendation, risk list, missing RFQ inputs, and preliminary manufacturing route.
Acceptance: Buyer confirms the proposed screw family and interface assumptions are compatible with actuator CAD.
Step 2
Sample parts with agreed inspection records, material evidence, preload or axial-play result, and packaging notes.
Acceptance: Parts pass fit, torque, backlash, and early duty-cycle checks without uncontrolled drawing changes.
Step 3
Controlled lot with CTQ checklist, sampling plan, traceability package, and delivery cadence.
Acceptance: Measurements repeat across the lot and procurement can release repeat orders against the same acceptance basis.
Yes. We support mutual NDAs before drawing exchange and can separate commercial RFQ data from controlled engineering files when required.
Yes. Send the current envelope, load target, stroke, and interface assumptions. We can return a feasibility direction and a list of values that must be locked before prototype machining.
Yes. Prototype and pilot lots can include material certificates, hardness results, lead accuracy, axial play, preload torque, CMM dimensions, and packaging notes depending on project scope.
Lead time is most affected by non-standard material, long internal thread grinding for inverted screws, custom shaft-end machining, heat treatment route, and the required inspection level.
