What Are The Surface Treatment Processes For Precision Parts?

Precision Parts Have High Requirements For Strength Toughness In Actual Work. Its Working Performance Service Life Are Closely Related To Its Surface Performance. The Improvement Of Surface Performance Cannot Be Achieved By Simply Relying On Materials, It Is Also A Very Uneconomical Approach. However, In Actual Processing, Its Performance Must Meet The Standard. At This Time, Surface Treatment Technology Is Needed, Which Can Often Achieve Twice The Result With Half The Effort. This Technology Has Also Developed Rapidly In Recent Years. In The Field Of Mold Surface Treatment, Mold Polishing Technology Is A Very Important Link An Important Process In The Workpiece Processing Process.

Strictly Speaking, Surface Treatment Heat Treatment Are Machining Processes, But In A Broad Sense, They Are Indeed Machining Processes, But Most Of Them Are Additive Machining. Some Friends May Understand The Difference Between Additive Subtractive Machining. Let Me Explain. The Cutting Machining We Usually Refer To Is Subtractive Machining, Because The Original Material Is Larger Than The Size We Want. After Machining, Its Volume Quality Are Reduced, Some Materials Become Powder, Such As Grinding Machines. The Surface Treatment Process Of Precision Parts Is Very Important In The Machining Process, So What Are The Surface Treatment Processes For Precision Parts?

Here I Will Tell You What I Know, I Hope You Can Clearly Understand That Surface Treatment Is Related To Materials. Let's Talk About Steel First! After All, The Most Commonly Used Material On Equipment Is Steel. Steel Can Be Treated By Electroplating Painting , Some Can Also Be Polished Brushed . Next, Let's Talk About Aluminum ! Most Of Them Are Oxidized .

1. Electroplating Is Generally Used To Plate Materials With Relatively Hardness Strong Anti-Rust Ability, Such As Chrome Plating, Nickel Plating, Titanium Plating, Gold Plating, Silver Plating, Etc. It Is A Chemical Method To Add Another Material To The Surface Of The Material, So That The Appearance, It Is No Different The Plated Material. Generally, The Materials To Be Electroplated Are Usually Better Than Ordinary Steel Materials. Some Are Harder, Some Have Good Conductivity, Some Have Bright Surfaces, Some Are Stainless, Some Are Corrosion-Resistant. In Short, The Materials That Can Be Used For Plating Are Ordinary Materials, They Must Have Unique Features.

2. The Other Is Baking Varnish, Which Is For Some Steels That Are Convenient To Plate Cannot Be Plated. The Most Typical Ones Are Q235 After Welding, A3 Steel. This Surface Treatment Is Generally Thicker As Precise As Electroplating. The Electroplating Layer Is Generally About 0.003mm, While Spray Painting Can Sometimes Reach 0.2mm, Which Are Completely Different Things. Therefore, Baking Varnish Cannot Be Used On Precision Parts, The Parts That Require Precision Cannot Be Painted.

3. Wire Drawing Polishing Are Actually Subtractive Surface Treatments Of Materials, Mainly For Stainless Steel. It Uses Some Fine Sand Wool Felt To Rub The Surface Of The Material At High Speed. Wire Drawing Polishing Are Both Needed Because The Surface Is Scratched Affects The Appearance, So This Process Is Needed.

4. Aluminum Precision Parts Are Usually Anodized. This Treatment Can Be Processed Into A Variety Of Colors, But Most Colors Are Recommended For Use On Equipment Because The Equipment Is Relatively Heavy. Try To Make It Colorful Too Gaudy. It Is Recommended To Oxidize It In Its Original Color. Anodizing Is Very Good For Aluminum, Which Can Make Soft Aluminum The Second Most Widely Used Material After Steel.

5. Although The Processing Technology To Improve The Surface Performance Of Precision Parts Is Constantly Innovating Upgrading, The Most Widely Used Technologies In The Processing Of Precision Parts Are Still Hardened Film Deposition, Nitriding, Carburizing. Because Nitriding Technology Can Obtain A Very High Level Of Surface Performance, The Process Of Nitriding Technology Is Highly Consistent With The Quenching Process Of Steel In Precision Parts, The Nitriding Temperature Is Very Low, So After Nitriding Technology Treatment, No Intense Cooling Process Is Required, So The Deformation Of Precision Parts Will Be Very Small, So Nitriding Technology Is Also One Of The Earliest Technologies Used To Enhance The Surface Performance In The Processing Of Precision Parts, It Is Also The Most Widely Used Technology At Present.
