Principle

How Titanium CNC Turning and Milling Work
Titanium CNC turning and milling use computer-controlled machinery for high-precision operations. The processes deliver quality titanium parts as follows:

1. CNC Turning

Rotates titanium workpieces on a spindle while cutting tools remove material

Shapes cylindrical forms like shafts and tubes

Achieves tight tolerances and smooth finishes through continuous rotation during precision cutting

2. CNC Milling

Employs rotating tools that cut stationary titanium workpieces

Tools move along multiple axes (unlike turning)

Creates complex multi-dimensional shapes: slots, holes, intricate contours

Ensures high precision and minimal material waste

Requires specialized tools/techniques for titanium's hardness

Maintains accuracy in complex designs

Types

Aluminum Polishing Techniques in CNC Processing
Different abrasive tools and techniques achieve varied finishes while maintaining the core objective of creating smooth, high-quality aluminum surfaces. Key CNC polishing methods include:

Mechanical Polishing
Uses high-speed rotating abrasive pads, belts, or wheels against aluminum surfaces. This most common method delivers smooth, shiny finishes for both decorative applications and functional parts requiring minimal friction.

Electrolytic Polishing (Electropolishing)
Immerse aluminum parts in an electrolytic solution under electric current to remove surface irregularities. Achieves smooth, bright finishes critical for industries like medical device manufacturing where hygiene and surface smoothness are paramount.

Vibratory Polishing
Places parts in a vibrating container with abrasive media. The resulting rubbing action polishes surfaces uniformly, making this method ideal for small parts and mass production with efficient processing times.

Buffing
A final-stage process using polishing compound-impregnated soft cotton wheels. Delivers high-gloss finishes for aesthetically critical applications like aluminum trim, automotive components, and kitchen appliances.

Challenges

Challenges in Machining 304 Stainless Steel
While offering significant benefits, 304 stainless steel presents these machining challenges:

Work Hardening: Tends to harden during cutting, accelerating tool wear if unmanaged.

Tool Wear: Demands sharp, wear-resistant carbide or coated tools.

Heat Buildup: Requires efficient cooling and controlled cutting speeds to prevent distortion.

Slower Cutting Speeds: Necessitate reduced speeds versus softer metals (e.g., aluminum, brass) to maintain tool life and accuracy.

Experienced CNC providers overcome these challenges using specialized tooling, optimized feed rates, and advanced coolant systems.

PACKING

Packing Process
Our packing method combines EPE foam and Kraft paper:

Inside: EPE foam protects aluminum profiles from impacts

Outside: Kraft paper shields against moisture and ensures a tight package

FAQ

• Q: How do you control quality?
• A: (1) Material Inspection - Check material surfaces and approximate dimensions.

(2) First inspection of production - ensure critical dimensions in mass production.

(3) Sampling inspection - check the quality before delivery to the warehouse.

(4) Preshipment inspection - 100% inspection by QC assistant before shipment.

• Q: Are the products of all the colors the same with the same surface treatment?
• A: No. About powder coating, the bright color will be higher than white or gray. About the Anodizing, colorful will be higher than silver, and black will be higher than colorful.

• Q: Can I get a quotation without drawings?
• A: Can your engineering team draw for my creativity? Of course, we are also glad to receive your samples, pictures or detailed size drafts for accurate quotation.

• Q: What’s your MOQ?
• A: We have no MOQ for our new customers, we are accepting small order to support your trial order, new design, and marketing development.

• Q: I want to keep our design a secret. Can we sign NDA?
• A: Sure, we can sign NDA before you send the drawing.
