How To Make a Perfect Surface Finishing Process For Products

 

A surface finish adds that authentic touch to an end product. Industries use the technique to boost their sales as it attracts more customers. Customers opt for surface finished products as their durability is higher. Such a trait cuts any additional maintenance fees. Both manufacturers and customers benefit from low price consumption. At Cncteck, we offer in-depth knowledge of the surface finishing process. Below are some of the services and intel that we offer.

What’s The Definition of Surface Finish?

The layout of a surface is known as a surface finish. Stemming to the level at which a polishing application is necessary. Surface roughness is one of the surface texture limitations. Furthermore, such parameters get rectified via the procedure. Later on, the project’s lifespan elongates, improving its quality and efficiency.

Factors Affecting Surface Finishing Process in Manufacturing Industry

• Cutting Tools

The metallic blades are ever helpful in the machinery process. As time advances, lasers replace metal blades as cutting instruments. High-pressure water assumes such a role. The modern age brings about new technology. All are leading to an advancement that comes with remarkable outcomes. One of them being smooth surface finishes. Laser cutting is greater than conventional. The high precision cutting reduces surface roughness. Also, a water jet cutter offers such benefits.

• Cutting Rate and Depth

The cutting depth is the ability of a cutting tool to venture a machined surface perpendicularly. Cutting rates differ depending on the material in use. The friction formed generates unwanted heat. A tool’s edge becomes blunt due to excessive heat rendering it ineffective.

• Temperature

Temperature hinders the volume production of workpieces. That leads to the expansion of metals and distorts polymers. It results in uneven surfaces, increasing the roughness. As a result, It is vital for temperatures not to exceed that of metal’s optimum. We get an even surface and also a higher volume production rate.

• Material Removal Rate and Feed

The material removed in a duration of time is known as the material removal rate. Such an aspect shows how long it takes for the removal to occur. Meanwhile, the total distance covered by a tool along a workpiece per unit of time is known as a feed. So, these two aspects affect the quality of the surface finishes heavily.

How To Measure Surface Roughness?

The roughness of a surface quantifies the amount of unevenness on a surface. The RA parameter represents all surface heights in a given area. Hence, all these are into three aspects; waviness, roughness, and form. Also, there are various ways of measuring surface roughness. They include; comparison measurement, non-contact measurement, direct measurement, and in-process measurement.

• Using Compare The Block

Usually, our customers ask for better product surface finishing after machining. The common level such as Ra0.8, Ra1.6, Ra3.2, and more. Like these common standards, we are able to make them with our CNC machining center, then using compare the block to compare.

Furthermore, if customers ask for the best finishing like Ra0.4 or Mirror finishing, how do we need to do them?  As usual, we will have to do an additional polishing process to meet the requirements. Also, we can use the precision grinding machine for outside surface to complete, of course, and we will use honing for hole finishing. our engineering team always makes a much better solutions for your products, in order to make your product’s precision and appearance perfect.

• Comparison Measurement

A surface finishing process uses the same equipment and material. Since the surface evaluation uses comparison techniques—senses like tactile and visual share the same sample with surface roughness. The method is best suited for non-critical applications since it is subjective during the process.

• Non-Contact Measurement

in place of stylus contact methods, we use non-contact techniques. The procedure involves sound or light as the medium. Optical tools divide into various categories, including white light and confocal interference. Also, electron microscopy is under the category but offers a small field of view.

• Direct Measurement

The evaluation of a surface finish is by drawing a stylus perpendicular. We measure from the surface following across its plane. Magnetic materials also measure surface roughness. An inductance picks up electromagnetic radiations measuring distances to the surface. Which later yielding to parametric values comparable to roughness level.

• In-Process Measurement

This technique allows constant monitoring of the surface. The machining process and other methods use the method extensively. The reason is that obtaining valuable feedback is easy. Also, more precise results compared to other methods. Thus, making in-process measurement better measurement.

Equipment Types That Inspect Surface Finish

• Microscopy Method

The main aim is to contrast and compare two different items. Results obtained are helpful concerning the un-evens found on the surface.

• Area Method

Such a technique measures the limited surface area provided. For instance; optical scattering, ultrasonic scattering, and capacitance probes.

• Profiling Method

A High-resolution probe measures the surface. Its sensitivity is much like a photograph needle. While that of the CNC probe isn’t that effective.

Selecting a Suitable Surface Finishing Process for CNC Machining

With the aid of CNC machining, accurate measurements are possible. Some of the readings may range as low as 0.025mm. Hence, we follow the necessary steps to obtain a specific outcome. A standard RA value usually is ideal; as it gets lower, the quality control increases. Most industries tend to use such an option. As the results, obtained are admirable and long-lasting.

In conclusion, it’s possible to obtain a suitable surface finish. At Cncteck, our years of expertise enable us to weigh the pros and cons of this method. Thus, making us good advisors on what technique to apply for desirable results. Kindly choose Cncteck if your project requires any finishing process.
