Start with the 3D model
A STEP file lets the team inspect the geometry directly. It is the best starting point for the holes, pockets, profiles, and overall envelope that determine whether the part fits the cell.
RAPID CNC MACHINING · SAN FRANCISCO
Rapid CNC Machining for Hardware Teams
Move from a STEP file to a real machining plan without a long email chain. twentyfour26 checks whether your part fits the cell, surfaces the details that matter, and machines accepted jobs in our San Francisco shop.
BUILT FOR THE PROTOTYPE LOOP
Small runs should not turn into a slow procurement project.
Hardware teams need parts while the design is still moving. A prototype is not a repeat-production purchase order, and a generic request-for-quote process often treats it like one. You send the model, wait for questions, explain the intent, and then wait again for a price that may not tell you what is actually possible.
Rapid CNC machining works when the path from geometry to a machinable plan is short and honest. That is the job twentyfour26 is built around. We focus on a defined machining envelope, then use software to read the part, identify its features, and check the choices that affect whether it can be held and cut.
The result is not a vague promise. It is a clearer next move: a part that fits can move toward a quote and machining plan. A part that needs changes comes back with the feature that is causing trouble, before you spend time waiting for a job that cannot run as drawn.
FROM CAD TO CHIP
How rapid CNC machining works here
The cell is deliberately narrow so the handoff can be faster, clearer, and easier to repeat.
- 01
Send the model
Upload a STEP file and include a drawing when tolerance, finish, threads, or inspection callouts matter. The file is the starting point, not an invitation to rewrite the same part in an inbox.
- 02
Check the part against the cell
The geometry is read for the faces, holes, pockets, and profiles that determine whether the part can be held and machined. The standard machine, stock, tools, and workholding keep the review focused on what affects your part.
- 03
Turn an accepted design into a plan
For a part that fits, the job can be mapped to stock, setup, and tooling, with a machining plan that supports a useful quote. This is where rapid work becomes more than a rush request: the choices are made before the spindle starts.
- 04
Cut and inspect in San Francisco
Accepted work is machined in the twentyfour26 shop. Keeping production and inspection close to the software loop helps preserve context when a prototype changes, a drawing adds a constraint, or the next revision needs a different answer.
A DEFINED BOX, NOT A BLACK BOX
What to send for the fastest review
The useful details are the ones that change how a machinist holds, cuts, or checks the part.
Add the drawing when details matter
Use a PDF drawing for tolerances, thread notes, finish callouts, and dimensions that are important to function. This gives the review a clear target beyond the shape alone.
Name the material and the job
6061-T6 aluminum is stocked. Brass, machining plastics, and mild steel can be reviewed on request. A sentence about what the part does helps the team understand which details deserve the most attention.
THE PARTS WE ARE SET UP TO MOVE
Rapid does not mean careless.
Fast machining is useful only when the part that arrives is the part you intended to test. The team plans around material, workholding, tool access, and the tolerances that are actually called out. That is why a defined operating range matters.
Standard tolerance is ±0.005 inches, or ±0.13 mm. With drawing review, twentyfour26 can plan to tolerances down to ±0.001 inches when the geometry and inspection requirements support it. There is no benefit in claiming every tolerance on every design. The right answer depends on the part, and the drawing is where you tell us what cannot move.
The same applies to materials and features. A simple aluminum bracket, a pocketed enclosure component, and a turned feature may all be candidates, but the machining plan comes from the actual geometry. Uploading the file is the fastest way to get an answer grounded in the work rather than a generic capability sheet.
WHEN THIS IS THE RIGHT PATH
Built around the work between revisions.
The goal is not to make every kind of part. It is to make the right parts easier to get moving.
Functional prototypes
When a design needs to become a testable metal part, the important question is whether the geometry can move into the cell cleanly. Send the model early enough to catch workholding or feature constraints before they become a delay in the build. It is especially useful when fit, feel, strength, or assembly cannot be answered with a render alone. It also gives the team a clear basis for the next design decision.
Design iterations
A revised prototype should not require re-explaining the same project from scratch. Keeping the review close to the machining plan helps the team focus on what changed in the geometry, the drawing, or the material callout. The clearer that change is in the file and drawing, the more directly the next review can start with the work that is actually new.
Small, engineering-led runs
For a limited set of parts that fit the operating range, a defined process is more useful than a broad capability claim. It gives the team a direct way to decide whether the work belongs in the cell and what it will take to cut it well.
FREQUENTLY ASKED QUESTIONS
Before you upload
What files should I send for rapid CNC machining?
Start with a STEP file. Add a drawing when tolerances, thread callouts, finishes, or inspection requirements matter. The drawing gives the shop the details it needs to plan the work and check the finished part.
What happens after I upload a part?
The geometry is checked against the cell, including the features that affect workholding and machining. When the part fits, the job can move into quoting and machining planning. When it does not, you get a useful explanation of the feature that needs attention.
What materials can you machine?
6061-T6 aluminum is stocked. Brass, machining plastics, and mild steel can be considered on request. If your alloy is not listed, send the part and material callout so the team can assess it against the cell.
Can you work to tight tolerances?
The standard tolerance is ±0.005 inches, or ±0.13 mm. With drawing review, the team can plan to tolerances down to ±0.001 inches when the part and inspection requirements support it.
