Vibratory grinding is an efficient and precise surface treatment process widely used for deburring, polishing and flattening of industrial parts. By optimizing the vibration frequency and media selection, the process can handle complex shapes and multiple materials while ensuring high precision and consistency. Next, I will take you to explore vibration grinding in depth, from basic concepts to practical applications, to understand this important technology from all aspects.
何 Is Vibration Grinding?
Vibration grinding is a common process in our processing . Its principle is to use the vibration force generated by the vibration motor to make the grinding medium and the workpiece rub and collide with each other in the grinding groove, thereby achieving grinding treatment on the workpiece surface. It can remove burrs, oxide scale and other defects on the workpiece, making the workpiece surface smoother and flatter .
What Materials Are Suitable Fまたは Vibration Grinding?
In my long-term practice, I have found that different materials have different adaptability to vibration grinding. This depends not only on whether the material is metal or plastic, or ceramic or composite material , but also on the basic properties of the material such as hardness and toughness, and is closely related to the precision of the processing technology.
Next, I will talk in detail about the performance of various materials in vibration grinding :
Metal Materials
Metal materials such as 6061 aluminum alloy (commonly used in structural parts in the aerospace field and housing frames of electronic equipment, etc.), 45 steel (widely used in shafts, gears and other parts in mechanical manufacturing), etc., have high hardness and can withstand the impact of abrasive media.
After vibration grinding, the surface finish is greatly improved. Metal parts such as the crankshaft of the automobile engine (generally made of high-strength alloy steel) and the automobile wheel hub (commonly made of aluminum alloy) have better performance after this treatment. In the manufacture of automobile engines, metal parts are subjected to vibration grinding to reduce the surface roughness, making the engine run more smoothly and the power output more stable, effectively improving the overall performance of the car.
According to relevant data, the surface roughness of metal engine parts that have undergone vibration grinding can be reduced from the original Ra3.2μm to Ra0.8 – Ra1.6μm, which greatly reduces the friction loss between parts, improves the mechanical efficiency of the engine, and increases the power transmission efficiency by 5% – 8%.
Plastic Material
Some thermoplastics, such as ABS plastic (widely used in home appliance housings, toys, office supplies, etc.), are suitable for vibration grinding. By properly selecting grinding parameters, plastic deformation can be avoided and surface quality can be improved.
For example, the shell parts of some children’s plastic toy cars (usually made of ABS material) feel smoother after vibration grinding. In addition, in the processing of plastic shells of laptop computers (mostly ABS or PC+ABS alloy plastics), vibration grinding can remove defects on the plastic surface, making its appearance more refined without affecting the original performance of the plastic, thus meeting the product’s aesthetic and practical needs.
Let’s take a certain brand of laptop computer shell as an example. After vibration grinding, the glossiness of the shell surface increased by 30% – 40%, and the surface roughness decreased from Ra1.6μm to about Ra0.8μm, which effectively improved the texture and appearance quality of the product, making it more competitive in the market, and reduced the product defective rate by 10% – 15%.
Ceramic Materials
Ceramic materials such as alumina ceramics (commonly used in electronic ceramics, cutting tools, wear-resistant parts, etc.) and zirconia ceramics (used in dental restorations, jewelry, high-end ceramic cutting tools, etc.) are brittle, so the vibration intensity and time must be controlled during grinding to reduce breakage.
Appropriate treatment can improve the precision and glossiness of ceramic products, such as fine ceramic crafts (such as blue and white porcelain bottles, whose bodies are mostly made of ceramic materials such as kaolin). In the production process of high-end ceramic tableware (such as bone china tableware, the main ingredients include bone ash, kaolin, quartz and feldspar, etc.), after carefully controlled vibration grinding, the surface of the tableware is smoother and more delicate, which not only improves the aesthetics, but also enhances the safety and comfort of use.
According to the world’s known experimental data, the surface roughness of ceramic tableware after optimized vibration grinding parameters can reach Ra0.4 – Ra0.8μm, and the glossiness of the glaze is improved by 20% – 30%, greatly improving the quality and market value of the product.
Composites
Composite materials such as carbon fiber reinforced epoxy resin composites (used in the aerospace field for aircraft wings, fuselages and other structural parts, and in the sporting goods field for high-end rackets, bicycle frames, etc.), glass fiber reinforced polyester composites (commonly used in shipbuilding, automobile body parts, building panels, etc.) can effectively improve their surface properties and enhance the bonding strength between different materials by adjusting the grinding process according to their composition.
For example, the performance of carbon fiber reinforced composite materials is more stable after grinding. In the aerospace field, the wings of a certain type of aircraft are made of carbon fiber composite materials. After vibration grinding, the flatness and smoothness of the surface are optimized, reducing air resistance and improving the flight efficiency and safety of the aircraft.
Based on wind tunnel test data , we know that after vibration grinding, the surface drag coefficient of the wing is reduced by 8% – 12%, and the fuel efficiency is increased by 5% – 7%, which effectively improves the performance and economy of the aircraft. At the same time, it enhances the connection reliability between structural parts and extends the fatigue life by 15% – 20%.
Vibration Grinding Core Parameters
In the operation of vibration grinding, the precise control of core parameters is crucial. They influence each other and are closely related, directly determining the grinding effect and quality. Among them, the frequency amplitude and load speed are the key parameters , which promote the grinding process .
Next, I will analyze in detail the importance of each of them and the synergy between them.
The Role Of Frequency Amplitude
Frequency and amplitude directly affect the grinding effect. Generally speaking, higher frequency and moderate amplitude can make the grinding media hit the workpiece more actively and speed up the grinding speed, but too high frequency may cause damage to the workpiece surface.
For example, when processing small precision metal parts, I will control the frequency to 1500-2000 times/minute and the amplitude to 3-5mm, which can ensure both efficiency and quality, and make the surface roughness of the workpiece reach Ra0.8-Ra1.6μm. This fine parameter adjustment makes the metal parts more accurate and reliable in subsequent assembly and use, and improves the stability of the entire product.
効果 Of Load And Speed
Load is the ratio of workpiece to grinding media. Appropriate load can ensure grinding uniformity. Speed is related to grinding efficiency. Too fast speed may cause uneven distribution of media.
I usually control the load at 30% – 50% of the volume of the grinding tank, and adjust the vibration plate speed according to the material and shape of the workpiece to ensure that each workpiece can be fully ground and reduce the scrap rate. When producing large batches of small metal parts, reasonable load and speed settings greatly improve production efficiency and ensure product quality consistency .
Significant Advantages Of Vibration Grinding
In the process of long-term involvement in production practice and in-depth application of vibration grinding technology, I have truly and deeply realized its huge value and influence. It not only qualitatively improves product quality and achieves a substantial leap in production efficiency, but also achieves remarkable results in cost control.
Surface Quality Improvement
After vibration grinding, the surface roughness of our workpieces can be reduced by 30% – 60%, tiny defects are removed, the appearance is more beautiful, and the corrosion resistance and wear resistance of the product can be improved.
For example, a set of stainless steel tableware will become brighter and more durable after being ground . In daily life, it not only increases the service life of the tableware, but also brings a better user experience, making it more popular in the market. Competitive.
効率性 And Cost-Effectiveness
Compared with traditional manual grinding, vibration grinding efficiency can be increased by 5-10 times while reducing labor costs. Moreover, the grinding media can be reused, which reduces material consumption costs and has obvious advantages in large-scale production.
For example, after a hardware processing factory adopts vibration grinding, the output can be greatly increased, the cost is reduced, and the profit margin of the enterprise has been significantly expanded, providing strong support for the sustainable development of the enterprise.
Multifunctional Applicability
We found that vibration grinding can process workpieces of various shapes and sizes, from tiny electronic parts to large mechanical parts. As long as the parameters are adjusted properly, the ideal grinding effect can be achieved, which is difficult to match by many other grinding methods. Metal housings of mobile phones and large engine crankshafts can be optimized through vibration grinding, meeting the diverse needs of different industries for product surface treatment .
