Efficient, High-Quality Processing Solutions for Titanium Integral Blades


Article Title: "Efficient, High-Quality Processing Solutions for Titanium Integral Blades"

In the aerospace industry, the overall blade of the low temperature compressor side is made from titanium alloy, while the overall blade of the high temperature turbine side needs to be made from high temperature alloys. In this article, we will explain how to successfully process these challenging materials using WOTEK's technology and knowledge.

Several key factors ensure successful machining. Three of the most important are:

• A five-axis machine with good dynamic characteristics.
• A set of CAM software featuring a five-axis processing turbocharger function.
• Tools and technology knowledge optimized for high temperature alloys and titanium alloys.

In the case of high-feed side milling, we use our own end mills, which are an effective method for machining challenging materials. Using a small cutting width, we can achieve higher cutting speeds and larger feeds and cut depths due to reduced heat, chip thickness, and radial forces.

When side milling titanium alloy with higher reach requirements, we use a medium-size replaceable milling head. This milling head has an optimized core, capable of achieving high rigidity in long overhangs, and performs excellently in mid-process situations that require good surface quality.

We face many challenges when machining parts with grooves and cavities. We use unique milling cutters designed specifically for slot milling to optimize both time and cost efficiency when machining small deep slots and cavities.

In terms of non-standard milling tools, we use reliable solutions designed based on specific models, suitable for rough milling in titanium integral blade slots. These non-standard milling tools can achieve excellent metal removal rates in these difficult rough machining processes, thus ensuring cost effectiveness.

For the semi-precision and precision machining of blades, we recommend using a point milling method due to the double-curved surface. This machining process ensures a controlled allowance and residual height for the precision machining process.

In terms of drilling, we use carbide drill bits. Their robust design, high-quality cutting edges, and wear-resistant top coating meet several key considerations (namely safety, consistency, hole tolerance, and quality) when machining tough materials like titanium alloys.
