How To Do Polishing Titanium Machining Parts Stepwise

 

A major process in improving the surface quality of titanium is polishing. The procedure involves removing part of the material surface to smoothen it. By polishing, titanium acquires improved aspects like corrosion resistance, strength, high-temperature resistance, and biocompatibility. At Creatingway, we follow a stepwise procedure to reduce errors and avoidable mistakes. Also, our experts have perfected how to polish the material using the correct process. Here is a guide on the surface finish and how it helps improve your product.

How To Define Titanium Parts Polishing?

The surface finish uses a polishing wax and buffing wheel to reduce the roughness of the surface. The titanium machining parts surface’s physical look, feel and touch increase upon application. It is always important to polish the part to add surface protection. Also, titanium polishing allows you to control the degree of polishing on small and complex titanium parts. The texture and color may vary according to the sandpaper grade used and the condition of the unpolished titanium.

How To Use a Mirror Finish in Polishing Titanium?

Stage 1: Cleaning and Degreasing Procedure

The titanium manufacturing method leaves a residue of grease and oil that acts as dirt in a titanium machining part. Therefore, it is vital to ready the surface by cleaning it as follows;

• Terminate oil residues by applying degreasing agents like spray rinsing
• Fill a container with bountiful clean water
• Immerse the titanium machining part into the clean water
• Add a small amount of your preferred cleanser; ammonia, glass cleaner, or mild soap
• Let the item soak for a few minutes
• Later rinse the part with warm water and let it dry

The use of bleach or chlorine is prohibited as it alters the aesthetical properties of the titanium machining part.

Stage 2: Sanding Procedure

Sandpaper aids in smoothening the surface part. There is a similarity between the precision grinding and sanding processes. We can eradicate the oxidized layer and a thin titanium coating with sanding. You need to adhere to these steps while practicing sanding;

• On the titanium machining part surface, apply the preferred lubricant.
• Place sandpaper of varying degrees at the hook pad attached to the drill. One starts with the rougher grades advancing to the softer ones.
• Then, a lubricant covers the sandpaper.
• With the sandpaper on the edge of the metal part, move it horizontally to the other edge.

Repeat the procedure till the entire surface gets polished. Also, it is crucial to maintain even pressure in all areas to avoid uneven patterns.

Stage 3: Buffing Procedure

To achieve the shiny glass-like appearance, we use the buffing process. one needs to;

• Cleanse the surface with an alcohol-cleaning agent
• A buffing wheel and a metal polish help in polishing the titanium machining parts’ surface
• The friction while rubbing increases the heat on the surface; thus, applying water cools it off

Stage 4: Ultimate Finishing

There may be visible marks on the titanium machining parts’ surface even after the buffing process. To hide the marks, you’ll have to;

• Take a clean towel and apply paint polish on it
• Gently rub the towel onto the surface, applying even pressure on all sides
• Spray water onto the surface and let it dry
• Use another towel and apply a sealant to it
• Rub the sealant towel onto the metal part and let it dry
• Finally, use a clean towel to wipe off the excess liquids

Various Methods of Surface Finish for Titanium Polishing

• Fine Polish

The fine polishing procedure gives the surface a more reflective look. One uses mirror wax and soft cotton buffing while exerting more pressure on the surface while polishing.

• Rough Polish

To achieve a rough polish, you use an abrasive buffing wheel. The wheel is made of titanium polish wax and silicon oxide. Apply a minimal polish force to the surface part. Such a procedure is best suited for corners of a titanium machining part.

• Mirror Polish

Titanium machining parts using mirror polish have a mirror-like surface appearance. One achieves the look by joining both polished wax and a soft buffing cotton wheel.

• Medium Polish

With rough polishing, visible marks are visible on the surface. We use polish wax and matting abrasive aluminum oxide wheels onto the part to avoid such lines—also, the smoothness and brightness of the surface increase.

Importance of Polishing Titanium Surfaces

• Improves the Lifespan

A titanium machining part with a superb finish tends to last longer because it is durable. Also, the parts are resistant to corroding environmental factors. With such aspects, the titanium machining part guarantees a greater lifespan.

• Improves Electrical Conductivity

for any metallic part, electrical conductivity is a crucial factor. Titanium materials could be a better conductor; polishing its surface improves its conductivity. There is little resistance in the metal as the electricity passes through it.

• Improves Beauty of The Part

Upon polishing the titanium, its functionality enhances, bettering its usability. Also, we improve the texture of the part, leaving it with a glossy look.

• Improves Wear Resistance

By polishing titanium, the frictional force on the surface reduces. Therefore, as the metal part comes into contact with a different surface, the wear is minimal. Such a feature improves the item’s lifespan, especially when there is friction involved.

In any metal structure, a good surface finish is key. The end-user and the manufacturer benefit from the features titanium polishing offers. However, the process requires caution as one practices it.
