Stainless Steel CNC Machining Service

Why Choose Stainless Steel for Your Parts?

Stainless steel is popular for many good reasons:

• It is Strong: It can handle tough jobs and heavy loads.
• It Fights Rust: Great for parts used outdoors or around liquids (corrosion resistance).
• It Looks Good: Shiny and clean appearance, easy to maintain through mirror polishing.
• It is Clean: Easy to sterilize, making it perfect for medical devices and food processing machinery.
• Handles Heat and Cold: Works well in heat-resistant alloys applications and even very cold places (cryogenic hardening can improve it).

We understand stainless steel deeply, including popular types like:

• 304 stainless steel: A common, versatile choice.
• 316 stainless steel: Even better at fighting rust, great for salty air (marine hardware) or chemicals. We often use 316L Surgical-Grade for medical parts.
• 17-4 PH stainless steel: Very strong and hardenable.
• Duplex stainless steel: A mix that is strong and fights rust well.
• Martensitic stainless steel: Can be made very hard, good for tools.
• 440C stainless steel: Often used for blades and bearings.
• 15-5 PH stainless steel: Strong, good for aerospace components.

Istar Machining can help you pick the best type for your project. We source quality materials from trusted suppliers like Outokumpu and Sandvik Materials, ensuring material traceability.

• Fast Turnaround: We work quickly to get your parts made, offering lead time optimization. Prototypes can often be ready in just a few days!
• Helpful Service: We offer Design for manufacturability (DFM) advice to make your parts easier and cheaper to produce. We use CAD/CAM integration with software like Mastercam, SolidWorks, Siemens NX, and Fusion 360.

Our Stainless Steel CNC Machining Capabilities

Istar Machining uses advanced machines and techniques to create your parts. Our Precision Engineering approach means we focus on every detail.

Core Machining Processes:

• CNC Milling: Using rotating cutters to remove material. We offer vertical milling and complex shapes with our 5-axis machining services. We also do CNC pocket milling and arbor CNC milling.
• CNC Turning: Spinning the metal part while cutting tools shape it, perfect for round parts like shafts. Explore our CNC Turning capabilities. We also offer multi-axis turning.
• Swiss Machining: Ideal for very small, complex parts often used in medical devices or consumer electronics. Check out our Swiss Machining solutions. This includes CNC swiss turning and swiss milling.
• Precision Drilling: Making very accurate holes, including deep-hole drilling.
• EDM (Electrical Discharge Machining): Using sparks to shape metal, great for hard materials or complex shapes. This includes sinker EDM machining.
• Laser Cutting & Waterjet Cutting: Cutting shapes out of flat sheets of stainless steel. We also offer CNC plasma cutting.
• Precision Grinding: Making surfaces extremely smooth and flat. This includes cylindrical grinding services and surface grinding services.
• Threading Services: Creating screw threads inside or outside parts (CNC threading).

Other Services:

• Sheet Metal Bending (CNC sheet metal bending)
• Custom Fabrication
• Assembly Services
• Reverse Engineering (making a part based on an existing one)
• Die-casting support (CNC die casting)
• Micro-machining for tiny parts.
• CNC Boring & CNC Carving
• CNC Welding integration

Advanced Technology:

We use modern machines from makers like Haas Automation, Mazak, DMG MORI, and Okuma. Our shop includes Vertical CNC mills, Horizontal lathes, and specialized Swiss-type machines. We use high-speed spindles, toolholders & fixtures, and robotic automation to improve speed and quality. We embrace Multi-axis capabilities and Hybrid Additive-Subtractive Systems for complex jobs.

Technical Specifications & Finishing Touches

We pay close attention to the details that matter:

Other Finishing Options:

• Bead blasting for a matte look
• Anodizing (mostly for aluminum, but sometimes requested)
• Laser engraving for part numbers or logos
• Cryogenic treatment for extra hardness
• Ensuring burr-free edges for safety and function
• Stress-relieving processes
• Non-destructive testing to check part quality without damage

We use GD&T (Geometric Dimensioning) principles and can perform Finite element analysis (FEA) to check designs. We focus on chip load optimization and correct feeds and speeds for the best results.
