Custom Stainless Steel CNC Parts Manufacturer for Non-Standard Projects
Prototeque manufactures stainless steel CNC parts with CNC milling and turning.
We machine 304/316 stainless steel. Tight tolerances. Fast quotes.
Stainless Steel Materials We Machine for CNC Parts
Every day, we machine 304, 316, 316L, and 17-4 PH stainless steel, along with their US and European equivalents.
Because we work with these grades daily, we have a proven method for each one.
We know how each grade cuts, so we choose the right tooling, speeds, feeds, and cooling.
As a result, you get higher efficiency, lower cost, and a better surface finish.
316L Stainless Steel Bushings for Continuous Galvanizing Lines
The three bushings shown here were custom-made from 316L stainless steel for a customer’s continuous galvanizing line.
They work under high temperature and highly corrosive conditions.
316L offers excellent corrosion resistance and stable performance.
We control the CNC machining process to ensure precision, fit, and long service life.
These are examples of our custom stainless steel CNC parts for demanding industrial applications.
How We Lower the Cost of Custom Stainless Steel CNC Parts
We don’t cut corners on quality. We cut costs by choosing the right process.
First, for hollow parts, we use hollow seamless tubes instead of solid bar. We have strong relationships with competitive raw material suppliers, so our purchase cost is about 10% lower than that of our peers. This saves material and machining time.
Second, for parts with a height or thickness up to 100 mm, we use CNC laser cutting for roughing and then CNC machining for finishing. As a result, we remove material faster and shorten cycle time.
Third, if no standard tube is available, we use cast rough blanks and then finish them with CNC machining. This avoids material waste and keeps the cost under control.
In short, we match the right material, the right roughing method, and the right finishing process to your part. That is how we make stainless steel CNC parts more cost-effective.
