Custom CNC Machined Mounting Plates
Custom machined mounting plates and base plates made to your drawings for industrial equipment and automation. One-off and low-volume orders; send CAD, material, quantity and inspection requirements for a quote.
Custom machined mounting plates connect your components to the rest of the machine. YSBK manufactures mounting plates and base plates from approved drawings and CAD files for industrial equipment, automation, tooling and custom machinery, including prototypes, one-off parts and low-volume batches.
Specify the hole pattern, locating features, mounting faces, material and finish your assembly needs. We review the defined component for manufacturability and quotation; the released drawing remains the basis for production.
Send the drawing and matching STEP file, quantity, material and finish. Highlight the features that control assembly and tell us which inspection records you need.

| What you need | What to specify for your RFQ |
|---|---|
| Materials | Aluminum 6061 or 7075, carbon or alloy steel, or stainless steel. State the exact grade and required condition; suitability is reviewed per project. |
| Machined features | Clearance and locating holes, counterbores, countersinks, threads, slots, pockets, steps and mounting surfaces, as defined on your drawing. |
| Surface finish | Anodizing or hard anodizing for applicable aluminum projects; plating, black oxide or other specified treatments subject to material compatibility and RFQ review. |
| Order type | Prototype, one-off or low-volume batch. Include the quantity for each part number and drawing revision. |
| Fit and inspection | Identify critical hole locations, locating diameters, flatness and datum requirements. Agree the inspection method and records before placing the order. |
| Delivery requirement | State your required arrival date and destination. Manufacturing and finishing timing must be confirmed after review; arrival and dispatch dates are different requirements. |
Which Features Matter for Assembly?
A bolt clearance hole, a locating hole and a mounting face serve different purposes. Show which features locate the mating component and which simply provide clearance. Where several holes locate one component, define their relationship to the drawing datums rather than relying on a chain of unrelated dimensions.
For a more detailed file checklist, see the mounting plate drawing guide. YSBK may flag unclear or conflicting requirements during review; changes to the locating strategy or approved tolerances require customer approval.
What Changes the Price of a Machined Mounting Plate?
There is no useful single price for every custom plate. Compare quotations against the same drawing revision and scope. The following details help explain why two similar-looking plates can receive different quotes:
- Material and blank size: alloy, condition, plate thickness and the starting stock required.
- Machining work: pockets, deep features, machining on multiple faces and the number of setups.
- Functional tolerances: locating-hole fits, hole-pattern position and mounting-face flatness, together with the agreed inspection method.
- Finish: treatment, masking and whether critical features must meet requirements after finishing.
- Quantity and documentation: batch size, first-part checks and required dimensional records.
Illustrative RFQ example: for a batch of 10 aluminum mounting plates, send the exact alloy, overall size and thickness, drawing revision, hole and thread definitions, finish and required delivery date. If two holes locate a mating component while the remaining holes are for bolt clearance, identify that distinction. This is an example of RFQ preparation, not a price, tolerance capability or completed customer project.
Use the CNC quote comparison checklist to compare machining, finishing, inspection and delivery scope together.
Materials, Finishing and Critical Fits
Existing project options include aluminum 6061 and 7075, carbon and alloy steels, and drawing-specified stainless steels. Specify the exact grade and condition rather than only writing “aluminum” or “steel.” The application and approved drawing determine the choice.
Identify any locating hole, thread or mounting surface affected by anodizing, plating or another finish. State whether acceptance applies before or after finishing, and show required masking. See the anodizing drawing callout guide for aluminum parts.
Agree Inspection Before You Order
Basic dimensional verification uses calipers, micrometers, depth gauges and height gauges. YSBK does not have in-house CMM or optical measuring equipment. If your drawing requires those methods, detailed positional verification or other specific measurement evidence, raise the requirement during RFQ review so inspection feasibility can be assessed before an order is accepted.
First-part photographs, key-dimension records and project-specific reports must be agreed during the RFQ stage; they are not included by default. Identify the characteristics to be checked, the method and the required record format. A photograph alone is not evidence that every drawing tolerance has been verified.
Ready to Request a Quote?
Send one RFQ package containing:
- The released 2D drawing and matching CAD or STEP file, with the same revision.
- Material grade and condition, quantity for each part number, and surface finish.
- Critical hole fits, positions, mounting-face requirements and relevant mating information.
- Inspection methods, records and any first-part approval requirement.
- Your required arrival date and delivery destination.
YSBK manufactures customer-defined components; approval of the complete machine, fixture or automation-system design remains with the customer. If you are preparing your first order, the first-time custom parts walkthrough explains the purchasing steps.
Frequently Asked Questions
Can I order just one custom mounting plate?
Yes. Drawing-defined one-off parts, prototypes and low-volume projects can be reviewed. Send the files and quantity so the manufacturing scope can be evaluated.
I only have a STEP file. What should I send?
Send the model with the known material, quantity and finish, and identify any missing requirements. A STEP file describes nominal geometry; it may not define thread specifications, fits, datums, tolerances or inspection needs. These requirements must be resolved in approved manufacturing documentation before production.
Can you quote a plate without a material or finish specification?
Tell us what is still undecided and how the plate will be used. Unresolved material, finish or inspection requirements must be identified during review; they should not be silently assumed in a final production scope.
How long will manufacturing take?
Timing depends on the reviewed drawing, material, quantity, finishing and inspection scope. Include the required arrival date with your RFQ. Confirm the schedule against the approved scope before ordering; this page does not promise a fixed lead time.
