Easiahome provides custom CNC machining services for OEM metal parts made to customer drawings. We review the material, geometry, critical tolerances, finishing, and expected order quantities to define the machining and inspection scope before quoting.
If you are sourcing a new component or qualifying a supplier for repeat orders, send the drawing revision, first-order quantity, and estimated annual demand. These details help us quote the initial order and evaluate how subsequent batches could be supplied.

CNC Machining Capabilities and Materials
We review CNC milling and turning requirements for parts such as housings, mounting blocks, brackets, and other components with machined faces, bores, slots, or threads. The machining route depends on the features, datum relationships, tool access, material, and inspection requirements.
For aluminum, carbon steel, and stainless steel projects, specify the material grade on the drawing or RFQ. If an alternate grade is acceptable, identify the properties and documentation it must meet. We can then review the proposed material against your requirements before it is used.
Tolerances, Finishing, and Inspection
Identify the features that control fit or function, such as a locating bore, a mounting slot, or the relationship between mating surfaces. Mark the relevant datums and include any gauging or reporting requirements with your RFQ. This helps us agree on which characteristics to check during sample review and which to monitor on repeat orders.
If the drawing specifies a coating or other finish, identify the dimensions that must meet tolerance after finishing. For threaded or close-fitting features, confirm any masking, gauging, or acceptance requirements during the drawing review. Let us know if the project calls for a dimensional report, CMM measurements, or material documentation so the quotation can include the agreed scope.
From Samples to Repeat Production
Sample review establishes the drawing revision and acceptance criteria for later orders. Before moving to repeat production, confirm the approved material and finish, any open drawing questions, and the inspection records required with shipments. Share the expected release quantity and schedule so we can review the production plan against your annual forecast.
Project Example: Zinc-Finished Steel Components
A steel component sampling project included machined bores, slots, and threaded features, along with a zinc finish. For this type of part, the sample review should identify which features govern assembly, how they will be checked, and which dimensions must meet drawing requirements after finishing. The approved drawing revision and inspection criteria can then serve as the basis for planning repeat orders.
Investment Casting and CNC Machining
For parts that begin as investment castings, we review the casting and machining requirements together. Identifying the machined surfaces early helps determine where to leave machining allowance, which features can remain as cast, and how the part will be located for finishing operations. If you already have a casting, send the casting drawing or model as well as the finished-part requirements.
What to Send for a CNC Machining Quote
- A dimensioned 2D drawing with the current revision and critical tolerances
- A 3D STEP file, if available
- Material grade and surface finish or coating requirements
- Sample or first-order quantity, estimated annual demand, and any planned release quantities
- Inspection records, material documentation, and target delivery date
Include the intended fit or function if it affects how we should review a feature. If the 2D drawing and 3D model differ, point out the discrepancy and identify the controlling revision.

Frequently Asked Questions
Can I request a sample before placing a production order?
Yes. Include the sample quantity, the checks needed for approval, and your expected production quantities so we can review both stages.
What if I only have a 3D model?
Send it for a preliminary review. Include any known material, finish, and quantity requirements. A dimensioned drawing helps confirm critical tolerances and acceptance criteria before production.
Can I request inspection documentation with my order?
Include the required records and the characteristics to be measured in your RFQ. We can review the reporting scope with the drawing and quote it as part of the project.
