Providing a Tight Tolerance on Large Parts
Tolerancing is a critical part of designing a product that needs to be top of its line in quality and durability. While each material has its ability to withstand certain machining and milling techniques, it’s important to keep the manufacturing tolerances tight where needed so you have a reliable product.
Not only does this extra step of quality assurance go above and beyond to keep your end users happy, but it ensures a higher level of reliability in the product. Tight tolerances ensure that your part performs optimally so that no retooling or overhauling is necessary. Our knowledgeable process engineers will advise you on what this means for your project, working with you to optimize your product with properly tightened tolerances and product durability.
Typically, Mountain Machine Works can hold a machining tolerance on large parts of + .0005” + .01mm. It is recommended that part features are thicker than 0.020” (0.51mm) in all regions to support the high dimensional tolerances possible with milled parts.
How Does CNC Milling Work?
CNC milling is a special manufacturing process that utilizes subtractive methods. First, a block of metal or plastic is inserted into the mill, and the operator creates a G-code program to rapidly mill out parts from the raw materials.
Different types of milling can create different effects on the products, such as vertical or horizontal milling, as well as 3-axis, 4-axis, 5-axis, and 9-axis milling which can handle different angles and balances based on the product specifications.
CNC Hard Milling
Hard milling is an innovative process for creating parts that are resistant to penetration, deformation and other impacts.
It requires special tools, understanding of material hardness, and can be used in a variety of applications from making modifications after heat treatment to producing hardened components independent of any prior processes.
Originally, hard milling was used to apply changes or additional machining to parts that had been reinforced through heat treating. It eventually became an individual process for the following reasons:
- The need for mold and die components that can be made quickly (faster time to market).
- The cost and time commitment required for EDMing, surface grinding, and jig grinding.
- Newer pre-hardened materials such as P20, H13, and 4140 are available.
- CAD/CAM and 3D machining are getting more sophisticated.
- There have been big improvements in machines, machine tools (cutters), and tool holding devices.
- The need to make new or replacement tooling components, reduce lead times, and improve surface finishes is increasing.
Mountain Machine Works has the capability to machine up to 50-55 Rc (Rockwell C) – providing an avenue for manufacturers striving towards high performance parts.
At Mountain Machine Works, we have extensive knowledge of the most common raw materials to help streamline your move from prototype to production.
Below is a sampling of these materials and how they react differently in milled parts applications.
Known for its tough properties like a high melting point and corrosion resistance, titanium is a high-quality material that can be efficiently milled for developing small parts.
As one of the most widely used and available metals for bulk manufacturing, aluminum is always on our CNC machines. This metal is flexible with different machining and milling techniques which means it can be milled, finished, machined, and tooled for just about any product part.
We can provide a range of plastic materials based on your needs from POM to ABS and Nylon. Whether you are looking for a durable plastic part or one with flexibility for temporary usage in the product design, we can supply the most cost-effective and reliable plastics for milling.
Using stainless steel for your parts is the perfect choice for a range of industries due to its versatility and strength. It is also highly resistant to corrosion and oxidation, making it well suited for parts that will be exposed to harsh environments or chemicals.
At Mountain Machine Works, we aren’t limited in the materials we can supply for your production needs. Other materials we offer include carbon steel, cast iron, ductile iron, and molybdenum. To learn more about alloys and other materials we can offer, talk to our team and discuss your project requirements.
Surface Treatments for CNC Milled Parts
We can provide a variety of finishes based on the material type and product need.
As one of the most cost-efficient finishing methods for inner functional components, this does not add any additional corrosion or wear resistance to the part but leaves it as-machined. Typically, as-machined finishing is good for inner functional components that won’t be customer-facing but may function with other products.
This type of finish, named for its smooth matte-black coloration, is common in applications that require corrosion- and wear resistance but may not be suitable for powder coating. This is a common finish to improve the appearance of the milled part where functionality under extreme conditions is a must.
This method heats the milled parts to an extreme temperature and brings them back down under controlled conditions. Depending on the time and temperature of heat treatment, it can provide the part with better harness, strength, and machinability as the chemical composition of the material is altered to benefit the product design. Typically, this method is dependent on the metal used and may not be optimal in all cases.
Type II Anodized
This finish comes in a range of colors and thicknesses. The paint creates a corrosion-resistant finish. Common colors available for anodization are clear, black, red, and blue, though other colors may be available upon request. Type III anodization is also typically available; this adds a layer of wear resistance to the milled parts in addition to the standard benefits of anodization.
One of the most popular methods of finishing CNC milled parts, closely tied with anodization, is powder coating. This method of painting a milled part uses powdered pigment which is then sprayed onto a part and baked in an oven. This oven-baked setting process makes the paint much more durable than standard painting methods, and it can be done relatively inexpensively. This also creates a corrosion- and wear-resistant layer and comes in a wide variety of colors that can be customized to match your company’s branding or customer preferences as needed.
Bead blasting allows for a measure of control in the texture and roughness of the milled parts surface. The bead range runs from 120 to 320 beads, ultimately leaving the product with a matte appearance.
Nickel electroplating is an effective way of creating a smooth, shiny surface that won't rust or stain. It applies a thin layer of nickel to the part's exterior, providing impressive corrosion resistance and extra protection against any adverse environmental conditions.

Precision Tolerances and High-Speed Milling with Mountain Machine Works
At Mountain Machine Works, we provide you with the advantage of high-speed milling without sacrificing precision tolerances. Skilled in a high metal-removal rate, we can reduce the cycle time and increase productivity for faster turnaround time.
Another advantage to this method, when done properly, is precision engineering for thin walls or harder metals that are at risk for greater tool deflection. High speed milling works under a decreased cutting force which creates a more efficient milling process under these conditions.
How Milling Differs from Turning and Boring
While milling is a mechanical process where the material is removed from the immobile stock material, turning and boring follow a different process that requires a lathe. For both turning and boring processes, the lathe’s cutting tool will work against the rotating workpiece, while a milled part stays stationary the whole time.
In short, boring is most used in removing materials from a piece internally, while turning removes materials from the outside; both require a rotating workpiece, while milling is best done with a stationary workpiece and rotating cutting tool.
