5 Axis Machining Services for Aluminum and Stainless Parts

Why Trust Our 5-Axis Machining Services?

Are you tired of receiving parts that are slightly out of spec? Worried that your complex designs will result in massive delays or exorbitant costs? We understand the frustration of dealing with shops that can’t handle intricate features. Our 5 axis machining services for complex aluminum and stainless parts are designed to eliminate these headaches, delivering precision and reliability for the global market.

Solving Complex Geometry Challenges

Standard 3-axis machines often hit a wall when facing undercuts, deep cavities, or organic shapes. We utilize simultaneous 5-axis milling to move the cutting tool along five different axes at once. This allows us to machine complex geometry components—like impellers and turbine blades—without the need for multiple heavy fixtures. If you can design it, we can likely machine it.

Achieving Tighter Tolerances (±0.01 mm)

Precision is non-negotiable in aerospace and medical sectors. Every time a part is moved from one machine to another, accuracy is lost. By keeping the workpiece stationary while the tool moves, we achieve superior tight tolerance machining. We consistently hold tolerances as tight as ±0.01 mm, ensuring your parts fit perfectly every time.

Faster Turnaround with Single-Setup Machining

Time is your most valuable asset. Our process relies on single-setup machining, meaning we machine all sides of a part in one go. This approach offers significant benefits:

• Reduced Lead Times: No waiting for multiple setups or fixture changes.

Our facility is equipped to handle the increased cutting forces required for these dense materials without compromising on speed or precision.

Handling Tough Alloys (304, 316, 17-4 PH)

Machining stainless steel requires rigid setups and advanced tooling strategies. We process a wide range of grades to meet specific mechanical properties:

• 304/304L: The standard for general enclosures and structural components.
• 316/316L: Essential for environments requiring high corrosion resistance.
• 17-4 PH: A precipitation-hardening grade used when high strength and hardness are non-negotiable.

We have optimized our processes for machining stainless steel to ensure consistent quality, whether you need a single prototype or a full production run.

Medical and Marine Industry Applications

Industries like medical and marine demand tight tolerance machining and superior surface finishes. In the medical field, we produce surgical instruments and implants that require bio-compatibility and intricate, organic shapes. For marine and harsh industrial environments, our Stainless steel 316 machining capabilities ensure parts resist saltwater corrosion and oxidation while maintaining structural integrity.

Combating Work-Hardening and Tool Wear

One of the biggest challenges with stainless steel is its tendency to work-harden if cut improperly. Our simultaneous 5-axis machines allow for multi-axis contouring that maintains optimal cutter engagement angles. This approach reduces heat buildup and prevents the material from hardening during the cut.

• Extended Tool Life: Proper engagement reduces wear, keeping costs down.
• Thermal Stability: Minimizing heat ensures complex geometry components stay within ±0.01 mm tolerance.
• Surface Integrity: Prevents surface micro-cracking and ensures a smooth finish ready for passivation or electropolishing.

We invest heavily in advanced technology to deliver top-tier 5 axis machining services for complex aluminum and stainless parts. Our facility is equipped to handle the most demanding geometries, ensuring that your designs are manufactured exactly as intended without compromise.

Simultaneous 5-Axis vs. 3+2 Machining

Understanding the difference between these methods helps us optimize your production costs and lead times. We utilize both strategies depending on the complexity of your complex geometry components.

• Simultaneous 5-Axis Milling: The cutting tool and the workpiece move along all five axes at the same time. This is critical for multi-axis contouring, such as machining impellers, turbine blades, and organic shapes where smooth curves are non-negotiable.
• 3+2 Machining (Positional 5-Axis): The machine locks the part at a specific angle before cutting. This provides extreme rigidity and is ideal for features like angled holes or pockets on flat surfaces. It allows us to produce CNC production parts faster by utilizing shorter, stiffer tools.

FAQs About 5-Axis CNC Services

Difference Between 5-Axis and 3-Axis?

The core difference lies in movement and efficiency. While 3-axis machines move linearly along the X, Y, and Z axes, simultaneous 5-axis milling adds two rotational axes (A and B). This allows the cutting tool to approach the workpiece from virtually any direction.

For you, this means single-setup machining. We don’t need to manually flip the part multiple times, which drastically reduces errors and improves precision for complex geometry components like turbines or medical implants.

Can You Machine Hardened Stainless Steel?

Yes, we routinely handle tough materials. Our 5 axis machining services for complex aluminum and stainless parts are optimized for rigidity. We excel at stainless steel 316 machining for corrosion-resistant applications and handle hardened alloys like 17-4 PH without compromising surface finish. We also process aerospace grade aluminum 7075 for high-stress, lightweight components.

What Is the Lead Time for 5-Axis Parts?

Because 5-axis machining completes parts in fewer operations, we often deliver faster than shops using conventional methods. Typical lead times range from 1 to 2 weeks depending on complexity. If you are looking to optimize your schedule, we have specific strategies for reducing the delivery time of CNC components to get your products to market sooner.

Do You Handle Prototypes and Production Runs?

We support your project from concept to mass production. We offer rapid prototyping services to verify designs quickly using CNC turn-mill services.
