The tightest tolerance in the city, held run after run. Lathes and machining centers on two shifts for monthly, quarterly and annual contracts, with repeatable parts down to 0.00007 in where the geometry allows it.
PDF, STEP, IGES, DXF or DWG. An engineer reviews the geometry, defines the machining route and answers with a real lead time — not an optimistic one.
We design and build the whole die set: punches, wire-EDM cut and ground die plates, fully mounted. You receive tooling that goes straight into the press.
We sit twenty minutes from the Otay Mesa port of entry. We handle shipments to plants in San Diego, Arizona and Texas with the export paperwork sorted from the first order.
No part leaves without going through the quality department. Calibrated instruments, a dimensional report and a certificate of conformance whenever your system requires one.
We are not a shop that does a little of everything. Each of these ten services has its own machines, its own procedure and the people who own it. However you search for it — a CNC parts manufacturer, a nearshore machining supplier, or an offshore alternative that happens to be twenty minutes from San Diego — it is all under one roof here. Pick the one that looks like your problem.
Runs of hundreds or thousands of parts under monthly, quarterly or annual contract, delivered in Mexico and the United States.

Gauges, core pins, molds, punches and die plates held to 0.00007 in depending on part geometry.

We design and build the complete die: punches, wire-EDM die plates, grinding and assembly, delivered ready for the press.

We build exactly what your drawing says — and if there is no drawing, we create one from the physical part.

We design, machine and assemble the fixture that lets the part load only one way: the right one.

Part numbers, lot codes, logos, barcodes and data matrix on metal and plastic, still readable after years in service.
View this serviceNot brochure promises: these are the six things our customers name when we ask why they keep sending us prints.
Grinding and fine machining for gauges, core pins, punches and die plates where 0.01 mm is already too much.
An engineer reviews the print, not a salesperson. You get the machining route, the proposed material and a real delivery date.
Every lot goes through dimensional inspection with calibrated instruments. Certificate of conformance available on request.
Twenty minutes from the Otay Mesa crossing. We ship to your plant or to your warehouse north of the border.
Turning, milling, wire EDM, grinding, welding, heat treatment and laser marking. Your part does not tour three suppliers.
On production projects we machine the sample part before you release the order. If it does not meet print, you pay nothing.
Sixteen years of audits, PPAP packages and on-time deliveries, summarized in one row of logos.
RD Maquinados began operating in early 2002. We are twenty-five people in a shop in Colinas de la Mesa, Tijuana, and we have spent more than two decades doing the same thing: machining parts that have to come out exact.
What changed over twenty-four years was the scale, not the standard. Today we are twenty-five people with CNC centers, wire EDM, precision grinding and a quality department with calibrated instruments — but the rule is the same one: if the part is not to print, it does not leave the shop.
This is the full route of a project. We publish it because most machining problems originate in the first two steps, and that is exactly where we spend the most care.
The drawing arrives as PDF, STEP, IGES, DXF or DWG. If all you have is the physical part, we scan it and draft the print ourselves.
Engineering reviews tolerances, material and workholding. If a dimension makes the part expensive for no reason, we tell you before quoting.
You get unit price, volume pricing, the proposed material and a committed delivery date. No fine print.
For production we machine the first article, measure it and send it over with its dimensional report for your approval.
We run the lot. If the part needs heat treatment, anodizing or laser marking, it happens here without leaving the shop.
Quality measures against the print, releases the lot and it ships to your plant in Mexico or your warehouse in the United States.
An automotive fixture and a medical core pin have nothing in common except that both have to come out exact. Here is what we build for each sector.
Assembly fixtures, stamping dies, shafts and line components for harness, seating and safety-system plants across Tijuana and Tecate.
Stainless, titanium and PEEK parts for medical devices, with fine finishes, controlled burr and material traceability.
Shop-floor tooling, gauges and components in aerospace aluminum and superalloys for suppliers in the Baja California aerospace cluster.
Precision-machined plates, bases and test nests, plus laser marking of part numbers and traceability codes.
Stainless spare parts and structures with sanitary finish for processing, filling and packaging lines.
Heavy work: shafts, bushings, pulleys, gears and plant machinery spares that cannot wait three weeks for an import.
Precision components under controlled drawings, with confidentiality, material control and part-by-part dimensional reporting.
No customer names, because nearly all are under NDA — but with the material, the tolerance and the outcome exactly as they happened.
Automotive
Complete four-station die for a copper terminal. Wire-EDM cut die plates, ground and mounted in the die shoe. Delivered assembled and tried out with the first thousand pieces run on our press.
Automotive
6061 aluminum base with interchangeable posts and ground locating pins. Cuts harness verification time from 90 to 35 seconds and removes operator reading error.
Medical
A run of H13 core pins holding diameter within 0.002 mm across the whole batch. Cylindrical grinding and final polish so the part releases from the mold without a witness mark.
We sent the print on a Tuesday afternoon and by Wednesday morning we had price and date. The fixture arrived exactly as drawn and needed no rework on the floor.
They solved a run of core pins another supplier could not hold in tolerance. Three years buying from them and we have not had a single rejection.
A shaft broke on a Friday with the line running. They machined it on Saturday and we were producing again by Monday. Not everyone does that.
Working with them removed the border from our problem list. They invoice, they ship, and the part shows up in our warehouse on this side without us touching it.
What buyers and manufacturing engineers ask us most before they send the first print.
Under 24 business hours from the moment the print arrives. If the project has several parts or needs specialty material sourcing, we tell you the same day and give you a firm date for the complete proposal.
Down to 0.00007 in (0.002 mm), depending on part geometry and material. We reach that with grinding rather than milling, and we reserve it for gauges, core pins, punches and die plates. Most production parts run between 0.0005 and 0.001 in, which is where cost and function balance out.
Both. We keep manual machines precisely for the one-off part and the urgent spare, and CNC centers with bar feed for runs of hundreds or thousands. There is no minimum order.
PDF, STEP, IGES, DXF or DWG. STEP leaves the least room for error because it carries the full 3D geometry. If all you have is the physical part and no drawing, we measure it here and draft it ourselves.
Yes, on request. Every part goes through dimensional inspection before shipping; the certificate of conformance and the dimensional report are issued whenever your system requires them, at no extra cost.
Yes. We deliver throughout Mexico and ship into the United States. We are twenty minutes from the Otay Mesa crossing and already serve customers with warehouses in San Diego, Arizona and Texas.
Send us the drawing in PDF, STEP, IGES or DXF. You get a technical proposal and pricing in under 24 business hours — and a free sample part when the project calls for it.
