New energy vehicle motors, inverters and electric drive casings

For the procurement needs of motor casings, end covers, inverter and controller casings, electric drive axles and reducer casings, process evaluation is carried out around bearing holes, sealing surfaces, assembly interfaces, heat dissipation structures and key hole systems.

PART SCOPE

Scope of parts that can be evaluated

The following classifications are used to help purchasers quickly confirm the direction of demand; whether it can be processed is still subject to review of drawings, materials, quantities, rough status and technical requirements.

01

Motor housing, end cover and bearing seat

02

Inverter, controller and charging module housing

03

Electric drive axle, reducer and supporting structural parts

EQUIPMENT MATCH

Equipment capabilities and project boundaries

1270 and 856 three-axis vertical machining centers are suitable for motor end covers, controller housings and small and medium-sized electric drive accessories; large housings or special clamping requirements need to be reviewed separately.

The repeated positioning deviations of the equipment are listed as 0.0015 mm for the 5041 equipment, 0.003 mm for the 1270 equipment, and 0.005 mm for the 856 equipment; this value is not equivalent to the final dimensional tolerance of the part. Final tolerances depend on dimensions, construction, materials, clamping, temperature, processing paths and inspection methods and are subject to written technical confirmation.

RFQ REQUIREMENTS

Inquiries and technical reviews are required

Drawings and versions	2D drawings, 3D models, drawing numbers, version numbers, assembly relationships and unchangeable functional interfaces.
Materials and blanks	Material grade, status, casting/forging/plate requirements, machining allowance and whether equivalent material recommendations are allowed.
Key requirements	Datums, key tolerances, roughness, sealing surfaces, heat treatment, surface preparation, cleanliness and functional requirements.
Quantity and delivery	Sample quantity, single batch quantity, estimated annual usage, destination country, expected delivery date, packaging and trade terms.
quality document	Material documentation, dimensional reports, traceability requirements, and scope of PPAP, control plans, MSA or other automotive project documents.

Please indicate bearing bore, seal groove, mounting surface, coaxial relationship, positioning, leakage control, surface treatment and cleanliness requirements. If the project involves braking, steering, suspension or other safety-related functions, the technology, quality system, traceability and regulatory requirements must be reviewed separately; this page does not constitute a commitment to mass production qualifications or system certification.

FAQ

Procurement FAQ

Can the housing bearing bore be committed to uniform tolerances?

Unified commitment cannot be separated from the drawings. The aperture, coaxial relationship and position must be confirmed based on the material, structure, clamping, temperature and detection methods.

Can castings or forging blanks be evaluated?

Yes, but you need to provide rough drawings, machining allowances, benchmarks, defect standards and material status.

Is the equipment deviation shown on the page equal to the part tolerance?

Not equal to. The repeated positioning deviation of the equipment is only used for preliminary capability description. The final tolerance of the parts must be confirmed in combination with the drawings, materials, span, clamping, temperature, processing process and inspection methods.

Start evaluation with drawings and project boundaries

Please submit drawings, materials, quantities, critical tolerances, quality document requirements, destination country and expected delivery date.
