CNC Hard Milling
Hard milling is a process that can be used to create parts that have a certain Rockwell hardness. This represents how resistant the part is to penetration and permanent deformation from another material.
The hard milling process differs from normal machining because it requires special equipment and understanding of material hardness.
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 reasons below:
- 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).
Thin Wall Turning
Thin wall turning is one of the most challenging processes in CNC prototype and production machining.
One of the most common difficulties when machining a product that must be turned is inaccuracy in the final product. Most of these products, like thin-wall tubing or pressure vessels, require a different machining approach that few shops have the know-how to machine. Because of the difficulty of manufacturing this type of product, costs from product loss and production time can be high.
Fortunately, Mountain Machine Works has a thin wall turning process that enables us to achieve higher degrees of precision and speed the production time up, reducing loss in the overall product run. We accomplish this through specialty tooling and fixturing proprietary to our process that we have developed over the last 40 years.
Accurate thin wall CNC machining is accomplished at Mountain Machine Works through specialty tooling and fixturing proprietary to our process.
Shaft machining is a critical part of several industry sectors such as aerospace, pharmaceutical, power generation, military, mining, and heavy equipment services.
This manufacturing process can be difficult to manage as these shafts must be able to withstand demanding tolerances no matter the metal type.
Types of shaft machining our shop is capable of producing include: eccentric, impeller, journal, main, output, pump, roll, and rotor shafts.

Reduce Costs Before Production
While prototyping is considered an up-front expense when creating or re-engineering product lines, it greatly reduces the long-term costs of the project and keeps overall turnaround short.
CNC prototyping features a range of benefits, such as ensuring no quality issues arise during manufacturing that would otherwise delay production. By preventing delays and quality control issues that arise during manufacturing, product lines can be re-established in short order.
Parts can also be customized completely to OEM specifications within a fine range of precision, preventing the need for additional, post-production quality assurance and product loss from low-precision manufacturing practices.
Savings from these associated costs are not commonly calculated into the final ROI, but make the manufacturing process faster and more cost-effective, improving the company’s bottom line per unit.
Dependable Turnaround Time: Machined Parts on Your Schedule
Your company is on a timeline. Every moment that a product line is delayed is another moment that your company is losing profits and your bottom line is shrinking.
