Other Stainless Steel Grades
Machmaster can review customer‑specified stainless steel materials based on project requirements.
Finishing solutions to meet appearance and functional requirements.
As Machined
The part is left as-is from CNC machining, offering a cost-effective solution with visible tool marks and a standard roughness of 3.2 μm (126 μin), plus deburring for safe handling.
Bead Blasting
Bead blasting produces a uniform matte finish by removing surface imperfections. Commonly used to improve appearance before anodizing, plating, or coating.
This dry finishing process applies powder to metal parts, then cures it into a tough, uniform coating. It offers excellent durability and is available in many colors and textures.
Polishing removes surface flaws and creates a reflective, smooth finish. It’s used to improve aesthetics, reduce friction, and prepare parts for secondary coatings.
Brushing applies a fine, directional texture using abrasive belts or pads. Often used for decorative metal finishes or to visually mask minor surface defects.
Passivation
Chemical treatment to enhance the corrosion resistance of metals by removing free iron from the surface.
Stainless Steel Production Capability
From prototype to production parts — support throughout product development.
Stainless Steel Prototypes
Design validation, functional testing, engineering samples.
Small Batch Production
Product launch, market testing, customized applications.
Repeat OEM Manufacturing
Long‑term supply, production components, replacement parts.
Tolerances
Standard machining toleranc：±0.05 mm
Precision features：±0.01 mm (depending on part design)
Actual tolerance depends on part geometry, material properties, machining requirements, and inspection method.

FAQs About CNC Stainless Steel Machining
What Stainless Grades Do You Offer?
We commonly machine SS 303, 304, 316, and 416. If you need custom grades, we can evaluate them based on your design.
Is Stainless Steel Hard To Machine?
Some grades like 304 or 316 are tougher to cut, but with proper tools and speeds, we achieve excellent results. For better machinability, SS 303 and SS 416 are ideal.
Can You Polish Or Passivate Stainless Steel?
Yes. We offer polishing, passivation, bead blasting, and custom surface treatments depending on your application.
Do You Offer Food-Grade Or Medical-Grade Stainless Parts?
Absolutely. SS 304 and SS 316 are both widely used in food, beverage, and medical industries, and we follow relevant standards.
What Is Your Typical Lead Time For Stainless Parts?
Rapid prototypes can be delivered in 5–7 business days. Mass production timing depends on quantity and complexity.
Do You Support Tight Tolerances On Stainless Steel?
Yes. We can hold tolerances as tight as ±0.01mm, with full QA documentation upon request.
