At Wisconsin Metal Parts, we provide precision CNC machining services designed to produce high-quality components with tight tolerances and repeatable accuracy. Our scalable machining processes support everything from prototype development to high-volume production, ensuring consistent part performance across every run. This department not only does stand-alone CNC work for our customers but also works in conjunction with our stamping and fabrication departments to do secondary operations and contributes to our assembly services. With both CNC milling and CNC turning capabilities in-house, we deliver comprehensive machining solutions that reduce lead times and simplify your supply chain.
Our CNC machining services cover a wide range of part geometries, materials, and production volumes. From castings and extrusions to bar stock and billet, we can help find a customized solution to your production needs regardless of volumes. This department supports a variety of applications including tooling, production, and fixture components as well as replacement and reverse-engineered parts. Deburring, leak testing and part washing are secondary operations we can perform in-house if your project requires them. Our experience in the aerospace, defense, automotive and medical industries means we know how to make parts up to your industry’s standards.
Our core CNC machining capabilities include:
Each project is supported by skilled machinists, advanced equipment, and detailed process control to meet your exact specifications.
Quality is built into every aspect of our CNC machining process. As an ISO 9001:2015 certified and ITAR registered manufacturer, we maintain strict quality and security standards. Our systems comply with NIST SP800-171, ensuring secure handling of sensitive and export-controlled data.
Partnering with Wisconsin Metal Parts ensures precision, efficiency, and consistency across every project.
What sets us apart:
We are here to serve you and help solve your manufacturing challenges.
WMP is an experienced supplier of custom metal parts for a variety of industries including aerospace, agriculture, medical and food and beverage.
CNC (Computer Numerical Control) Machining is when pre-programmed computer software controls the movement of tools in machinery. There are many tools available for CNC machines, allowing for a wide range of processes, features and finishes for any given project. These tools remove layers of a material from a stock piece and produces a uniquely designed part. This includes processes like drilling, milling, turning, grinding and more. The CNC process is effective for a wide range of materials and can be automated, allowing for high precision and accuracy. CNC Machining is considered a subtractive manufacturing process, since material is removed from the stock piece. CNC is a great option for many manufacturers looking for consistency and quality.
Typically, we work with castings like aluminum, zinc, steel, and stainless steel. We also work from billet in aluminum, steel, stainless, copper, brass, bronze, tool steels, extrusions and machine some plastics.
Our lead time is an average of 3-4 weeks, but times depend on the complexity of the parts, subcontracting and material availability. We can give you a better delivery estimate if we can see a part drawing first.
Blanket orders are also an option that allow us to plan and work ahead so we can get the parts to you exactly when you need them. Blanket orders can also cut costs by reducing setup times and material costs.
Production orders can range from 10 -10,000 pieces. Smaller prototyping orders can be made in our tool room if it is a good fit for both parties.
Depending on the application, we can machine to part tolerances of +- .0005 inch
There are many ways to make a single part. Send us your drawings and Wisconsin Metal Parts can find you the most cost-effective way to make your part with our many capabilities.
Our variety of machines include Vertical and Horizontal CNC mills, Sub-Spindle and CNC turning centers with live tooling.
We have up to 5-axis capabilities
Milling – Our largest machine travel is 34 x 64”
Turning – 3” through spindle capacity
The main cost driver is setup time. Having blanket orders in place that allow us to minimize setups is one way to help control those costs. Proper tolerancing is another factor. Asking for tight tolerances to be held only where they are needed will also help control costing.
