High-Quality CNC Machining & Surface Finishing
Expertly Crafted Parts, On Time, Every Time.
Delivering precision-machined parts with expert CNC milling, finishing, and engineering support, from prototype to production
Allegro Precision simplifies your manufacturing process by handling machining, finishing, and coordination under one roof.
From tight-tolerance milling to plating-ready finishes, we deliver consistent quality without the delays, handoffs, or headaches of managing multiple vendors.
Finishing That Sets You Apart
Precision You Can Trust
Faster, More Reliable Lead Times
True End-to-End Manufacturing
SOME OF
OUR PARTNERS
Full-Service Machining and manufacturing
3 and 4 axis
milling
We will offer on-demand CNC machining services to startups, product design firms, and R&D departments that need high-quality prototypes quickly and reliably. Services include CNC milling and turning of metal and lasered parts, from CAD to delivery.
o Our parts tolerances are held to +-.004 inch, with +/- .001 achievable where necessary.
o Quick-turn prototyping (1–20 parts)
o Low-volume production (up to 500 units)
o Material capabilities: Aluminum, Stainless Steel, Plastics (Delrin, ABS, Nylon), Brass, and Titanium.
Design, development
and optimization
Our experienced team specializes in mechanical design, drawing creation, specification development, and process documentation. We can use your CAD file, or create one for you.
Bright Dip and
Plating Processes
Bright Dip line specifically designed for brass parts that demand a vibrant and bright appearance. Additionally, our tarnish inhibitor ensures the long-lasting brightness of brass components. Our strategic partnerships with local vendors enable us to offer a wide range of plating processes to meet your unique requirements.
Ultrasonic cleaning services: Our three ultrasonic cleaning baths enable us to thoroughly and efficiently clean your precision components. High-frequency sound waves will effectively remove contaminants and achieve a pristine, debris-free surface.
Deburring and
Polishing
Finishing: Deburring, bead blasting, anodizing, powder coating. Hardening is available.
40 years of experience in Engineering,
machining and manufacturing
We have broad and deep experience in both prototype development and high-volume machining. Our experience uniquely positions us as an excellent supplier of small, high volume parts requiring a highly aesthetic surface finish. If supply chain issues are motivating you to "reshore" production back here to the USA look no further than Allegro Precision. We are your trusted local shop, dedicated to delivering exceptional quality and keeping your sources close to home.

We Make product creation Easy!
1
Initial Contact & Project Review
The customer reaches out with drawings, CAD files, specs, quantities, and timeline requirements. Allegro reviews part geometry, tolerances, materials, and finishing needs to ensure manufacturability.
2
Engineering & Design Support
If drawings need refinement, Allegro provides mechanical engineering input, design optimization, and process recommendations to reduce cost, improve quality, or streamline production.
3
Quoting & Lead Time Confirmation
A detailed quote is provided outlining machining, finishing, plating coordination (if required), quantities, and confirmed lead times including expedited options if needed.
4
CNC Machining
Parts are precision-machined using 3-axis and 4-axis CNC milling equipment. Tight tolerances and repeatability are maintained across prototype, low-volume, and high-volume runs.
5
Deburring & Surface Finishing
Machined parts move into in-house finishing processes including deburring, polishing, vibratory finishing, or mass finishing to achieve the required aesthetic and functional surface quality.
6
Cleaning & Preparation
Parts are ultrasonically cleaned to remove oils, debris, and contaminants, ensuring they are clean, consistent, and ready for plating, assembly, or final use.
7
Plating & Surface Treatments (If Required)
For plated or anodized parts, Allegro performs in-house bright dip processing for brass and coordinates nickel, chrome, or anodized finishes through trusted local partners.
8
Final Inspection & Quality Check
Parts are inspected to confirm tolerances, surface finish, and overall quality meet specifications before final approval.
9
Packaging & Delivery
Parts are packaged appropriately (including retail packaging if required) and shipped according to the agreed timeline, with expedited options available when needed.
FAQS
Commonly Asked CNC MILLING AND FINISHING Questions
Have questions about CNC milling, tolerances, materials, or finishing options? We’ve got answers.
What tolerance can you hold?
Typically tolerances are held to +-.004 inch, with +/- .001 achievable where necessary.
What is your average Lead Time?
Contact us with details of your components, and we will be happy to quote a lead time and deliver the parts on time. With a new machine added in May of 2023, we have available capacity!
What materials can you machine?
We routinely work with Mild Steel, Tool Steel, Stainless Steel, Aluminum, Brass, and plastics.
What size stock can your machines accommodate?
Our Haas VF2 machines can handle stock up to 30 x 16 inches. Workholding issues sometimes lead to an effective work area that is less, depending on the part.
What plating options do you offer?
We do not have plating in-house. We have a Brite-Dip process for Brass components in-house. We are happy to manage plating needs for you through our local partnerships. Available finishes are Electroless Nickel, Bright Nickel, and Chrome. We can also handle heat treat processing for you through a local vendor-partner.
