Titanium is a kind of light metal. The cutting force of CNC machining titanium parts is higher than that of steel of the same hardness. It is commonly used in the fields of aerospace, electronics and other fields in CNC machining. After a period of time, CNC machined titanium parts will lose their luster and surface scratches. Titanium polishing can restore the original metallic luster, such as mirror surface. This article will describe how to clean titanium and CNC machining titanium parts polishing knowledge.
The polishing process of CNC machining titanium parts is not difficult. It needs to be polished according to the different conditions of the titanium parts, such as scratches and stains that cannot be cleaned.
How to clean CNC machining titanium parts?
Straightness is a form tolerance introduced in GD&T, which is used to indicate that the linear elements on the CNC lathe parts maintain an ideal straight line state, which is commonly referred to as the degree of straightness. Straightness tolerance is the maximum amount of variation allowed by the actual line to the ideal straight line, and there is no benchmark requirement. The standard form of straightness is used to ensure uniform two-dimensional tolerances on the surface of CNC lathe parts, as well as the axis straightness used to control the central axis of the part.
Step 2: Take out the CNC machined titanium parts and rinse them with clean water. Take a dry soft towel or cotton cloth and gently try the titanium to wipe in circular motions.
Note: Do not rub non-ferrous CNC-machined titanium parts.
After finishing the above two steps, the CNC machining titanium parts have been cleaned up, and the next step is the polishing process of the CNC machining titanium parts.
According to different processing requirements and applications, the methods and tools used in the polishing of CNC machining titanium parts will be different. The following is a brief introduction to the different levels of polishing.
1) Rough polishing: Use titanium alloy special hemp wheel or wool wheel and special titanium wax to polish the CNC machined titanium parts to achieve a smooth surface. Pay attention to polishing strength and direction.
2) Medium polishing: Use titanium alloy special polishing coarse cloth wheel or fine wool wheel and titanium alloy special polishing wax for polishing to remove the lines left by rough polishing until the surface of the product is bright.
3) Fine polishing: The titanium alloy special cotton wheel and titanium alloy fine polishing wax are used to make the CNC processed titanium parts achieve high brightness. There are also some slight textures on the surface of titanium products.
4) Mirror polishing: Use titanium alloy special bleached cotton cloth wheel and titanium alloy special mirror polishing wax to remove the slight texture on the metal surface.
Summarize
It should be noted that the above-mentioned process of polishing of CNC machining titanium parts requires professional polishing technology and proficiency in order to meet the polishing requirements, which is mainly manifested in the details of polishing force, speed, direction and so on. CNCMF provides professional polishing services for CNC machining titanium parts, as well as sandblasting, anodizing, painting, powder coating, passivation and more metal finishing surface treatment services.
