Drawing review
Geometry, tolerances, datums, and acceptance criteria.
Build-to-print metalworking
CNC machining services in Tijuana, Mexico
Industrial components manufactured to drawing and agreed criteria, from manufacturability review through final inspection.
Representative image. Final capability is confirmed against drawing, material, tolerance, and volume.
Capabilities
Quotation based on the actual requirement
Every component is evaluated according to geometry, material, tolerances, finish, volume, and inspection method. This review prevents unsupported capability claims.
MJC can integrate machining into a wider subcontract-manufacturing flow including assembly, coating, packaging, or logistics, subject to defined scope.
Process route
Machining sequence and complementary operations.
Agreed inspection
Dimensional controls based on criticality.
B2B delivery
Integration with assembly, packaging, and owned logistics.
Required information
A complete request accelerates technical and commercial review.
- 2D drawing and, when available, a 3D model.
- Material and supply condition.
- General tolerances and critical characteristics.
- Required finish, treatment, or coating.
- Lot quantity and estimated demand.
Part control
The control plan is defined according to risk, the drawing, and customer requirements.
- First-piece approval.
- In-process verification.
- Final inspection and agreed records.
- Identification and packaging to specification.
Frequently asked questions
Which materials can MJC machine?
Materials are confirmed per project after reviewing grade, condition, geometry, and drawing requirements.
Which tolerances can MJC hold?
We do not publish a generic tolerance. Capability is validated by characteristic, process, equipment, and inspection method.
Can I send STEP or DXF files?
Yes. They can be shared during review; the controlled drawing remains the acceptance reference.
Process
From technical review to delivery
A clear workflow for integrating processes without losing visibility.
Review
We analyze drawings, materials, volume, acceptance criteria, and risk.
Proposal
We define scope, responsibilities, process route, and control points.
Validation
We release a sample or first piece before recurring production.
Production
We execute, inspect, report, and continuously improve the process.
