Precision Machining and Metrology

Custom CNC machining, precision turning, fixture planning, and measurement support for humanoid actuator housings, flanges, shafts, bearing seats, and interfaces.

Best Fit ForFor teams that need reliable mechanical execution after the actuator architecture is defined.

Capability Boundary and Buyer Fit

This capability should help a serious buyer decide what evidence is needed before releasing drawings, samples, NRE, pilot POs, or repeat production.

Best buyer fit

For teams that need reliable mechanical execution after the actuator architecture is defined.

Primary evidence metric

CTQ measurement coverage: Drawing dependent

Risk to control first

Machined parts meet isolated dimensions but fail assembly fit

Capability Highlights

  • Precision machining review for tight actuator housing and interface tolerances
  • Inspection planning for bearing seats, concentricity, flatness, runout, thread quality, and surface finish
  • Prototype and pilot machining coordination with FAI and outgoing dimensional records

Typical Engagement Scope

  • Humanoid actuator housings and covers
  • Output shafts, flanges, bearing carriers, and torque sensor interfaces
  • Pilot-volume precision actuator mechanical parts

Execution Focus

  • Turn actuator tolerance stack into manufacturable drawing notes and inspection gates
  • Align material, surface treatment, datum structure, and assembly fixture strategy
  • Control first article inspection and pilot-part consistency

What This Capability Must Prove

Engineering boundary

What the buyer owns, what the supplier can review, what is frozen, and what remains an open design trade-off.

Manufacturing evidence

DFM notes, machining route, supplier scope, first-article checks, CTQ inspection, assembly controls, or sourcing records.

Validation evidence

Torque-speed, backlash, thermal rise, dynamic load, FCT, burn-in, CMM, traceability, or corrective-action records as relevant.

Commercial handoff

NRE scope, prototype quantity, pilot forecast, reporting format, packaging requirement, Incoterms, and repeat-order assumptions.

Redirect Before OEM Review If

  • The buyer still needs to choose which actuator family or component stack should be quoted. Review product families
  • The buyer is trying to match the capability to a robot program scenario first. Review solution routes
  • The inquiry is missing CAD, torque-speed data, duty cycle, quantities, schedule, or validation requirements. Prepare RFQ baseline

Program Evaluation Matrix

Program MetricTypical RangeProcurement Value
CTQ measurement coverageDrawing dependentActuator reliability depends on small mechanical dimensions that must be measured consistently.
Bearing-seat tolerance riskLow, review needed, fixture critical, or redesignBearing fits, concentricity, and runout often decide actuator noise, backlash, heat, and service life.
FAI and CMM report scopeVisual, critical dimensions, full FAI, or pilot samplingBuyers need to know which dimensions will be measured, how often, and which records ship with samples.

Buyer Inputs and Supplier Outputs

A capability page should turn procurement interest into a usable evidence agreement. These inputs and outputs keep the RFQ from becoming a vague capacity conversation.

Buyer Should Prepare

  • 2D drawings, 3D CAD, material, surface treatment, tolerance class, and CTQ dimensions
  • Inspection report requirement and sample quantity
  • Assembly responsibility and expected pilot volume

Supplier Should Clarify

  • Turn actuator tolerance stack into manufacturable drawing notes and inspection gates
  • Align material, surface treatment, datum structure, and assembly fixture strategy
  • Control first article inspection and pilot-part consistency

Evidence Chain Across the OEM Program

The useful question is not whether a supplier can make one sample. The useful question is whether the evidence from that sample can survive the next release gate.

GateBuyer InputSupplier Output
Requirement BaselineJoint CAD, drawing revision, target performance, package limits, duty cycle, and buyer-owned design boundaries.Feasibility comments, DFM questions, missing-data list, risk register, and quote-scope assumptions.
Sample EvidencePrototype quantity, acceptance limits, CTQ dimensions, test method, report format, and open trade-offs.FAI/CMM scope, sample acceptance record, torque-speed or thermal evidence, issue log, and next-build recommendations.
Pilot ReleaseApproved sample reference, drawing and BOM revision, pilot quantity, incoming inspection plan, and forecast.Release checklist, in-process gates, outgoing report, serial traceability, packaging plan, and corrective-action owner.
Repeat ProductionChange-control rules, demand plan, spare ratio, destination rules, and escalation path for field issues.Revision lock, lot records, yield trend, packaging consistency, export documentation, and issue containment path.

RFQ Preparation Checklist

  1. 2D drawings, 3D CAD, material, surface treatment, tolerance class, and CTQ dimensions
  2. Inspection report requirement and sample quantity
  3. Assembly responsibility and expected pilot volume

Risk and Mitigation

  • Machined parts meet isolated dimensions but fail assembly fit: Review datum scheme, tolerance stack, bearing fit, shaft alignment, and assembly fixture before production.
  • GD&T is unclear or disconnected from actuator function: Tie datums, runout, flatness, perpendicularity, and inspection method to bearings, output flanges, and robot-side interfaces.
  • Surface treatment changes critical dimensions: Define masking, coating thickness, post-treatment inspection, and accepted fit ranges for bearing and sealing surfaces.

This form is prefilled with Precision Machining and Metrology. Include CAD, drawing revision, CTQ list, torque-speed target, validation evidence required, prototype quantity, pilot forecast, reporting format, and delivery country.

Contact

Use a business email so engineering and purchasing notes can stay traceable.

Program Scope

These fields route the inquiry by humanoid subsystem, project stage, volume, and logistics.

Torque, Motion, and Thermal Targets

TBD values are acceptable, but blank torque and duty-cycle data usually blocks sizing.

Mechanical Interface and Reducer

Package and backlash constraints decide whether an existing platform can be adapted or a new stack is needed.

Electrical, Control, and Validation

Include the control boundary and acceptance evidence needed before pilot production.

Complete 8-point engineering datasets are prioritized for technical receipt within 24 hours, DFM questions within 3 business days, and quote direction within 7 business days after the minimum data is complete; actual timing depends on scope, attachment quality, and engineering availability.

Buyer FAQ

Can you provide only machined parts?

Yes. We can support standalone precision machined actuator parts or complete custom actuator assemblies.

What drawings are needed for a CMM quote?

Send 2D drawings with datums, tolerances, CTQ dimensions, material, surface treatment, inspection scope, and sample quantity.

Can CTQs be defined jointly?

Yes. If the buyer sends assembly intent and risk areas, CTQs can be refined before FAI and pilot inspection planning.
