Glossly polished SS304 CNC machining prototypes used for electric appliances

At Metalstar, here are the key steps we follow to produce perfect-looking stainless steel parts through our rapid prototype CNC machining process:

Material Selection:
We start by carefully selecting the optimal stainless steel alloy for your application, taking into account factors like corrosion resistance, strength, machinability, and surface finish requirements. Our team of materials experts ensures we use the right grade of stainless steel to meet your specifications.

CAD Design and Programming:
Our in-house engineering team works closely with you to review the CAD model and optimize the part design for CNC machining. We then develop detailed toolpaths and G-code programs to ensure precise, efficient material removal and the desired surface finish.

Workholding and Fixturing:
Proper workholding is crucial for maintaining tight tolerances and achieving a perfect surface finish. We utilize a range of advanced clamping and fixturing solutions, including vacuum chucks and custom-engineered fixtures, to securely hold the stainless steel workpiece in place during machining.

Cutting Tool Selection:
Selecting the right cutting tools for stainless steel is key to producing parts with a flawless appearance. We use carbide and high-speed steel tools with specialized coatings and geometries that are optimized for stainless steel machining, minimizing tool wear and ensuring a consistent, high-quality finish.

Machining Optimization:
Our experienced CNC machinists fine-tune the machining parameters, such as spindle speed, feed rate, and depth of cut, to achieve the optimal balance between material removal, surface finish, and part accuracy. We also employ in-process monitoring and adjustments to maintain tight tolerances throughout the machining cycle.

Post-Processing:
After machining, we carefully inspect the parts and perform any necessary deburring, polishing, or secondary operations to ensure a perfect, blemish-free surface. Our attention to detail in this final stage is what truly elevates the quality of our stainless steel prototype parts.

By following these meticulous steps, Metalstar is able to deliver stainless steel prototype parts that meet the most demanding aesthetic and functional requirements of our customers, consistently and efficiently. Contact us today to learn more about our rapid prototyping capabilities.
